• Three Flow Configurations to Choose From
• Biocompatible Flow Paths

With three versions to choose from, Upchurch Scientific® Switching Valves offer several flow distribution options. Each valve has a low swept volume, can withstand pressures to 500 psi (34 bar) and is chemically inert and biocompatible. The PEEK and PTFE resin construction results in a valve as durable as it is economical. Each V-100 Series Switching Valve has 0.040"" thru-holes and is supplied with Flangeless Fittings for use with 1/16"" OD tubing. To use these valves with 1/8"" OD tubing, simply replace the supplied fittings with 1/4-28 Flangeless Fittings(You may notice a slight back pressure at higher flow rates, due to the 0.040"" thru-holes in these valves).
To operate, all ports must be either connected to a line of your system or plugged. Built-in positioning detents allow these valves to snap into place, ensuring the thru-hole is properly aligned.
Standard manual valves (V-100D, V-100L and V100T) measure 1.80"" (45.7 mm) in length. Bulkhead versions (V-101D, V-101L and V-101T) are 2.18"" (55.4 mm) long.
Each of the Upchurch Scientific 4-Port Switching Valves is available in standard manual and bulkhead mountable manual configurations. Bulkhead mounting specifications are included and are also available. The bulkhead mountable manual configuration can also be mounted on our M-615-1 Valve Bracket. DC gear motor actuated versions are also available. The bulkhead mountable manual configuration can also be mounted on our M-615-1 Valve Bracket. DC gear motor actuated versions are also available.
Please contact Upchurch Scientific for custom configurations for instrument manufacturers. High pressure switching valve options are available.
Protect sensitive system components (such as a column) during a cleaning cycle with our Diagonal Flow Switching Valve (""D""). This valve eliminates the need to remove, plug and reconnect a low pressure column.
A typical application for a Right Angle Flow Switching Valve (""L"") is column switching, allowing two columns to use one detector. Detector switching is another common application for this valve. Plug off the extra port with the included plug.
Your detector switching application may require the flexibility of routing the column effluent to both detectors simultaneously while retaining the ability to isolate each detector. Use our 3-Way Flow Switching Valve (""T""), plugging off the fourth port with the included plug."

"Choose from our line of Biocompatible and Stainless Steel BPR Assemblies, each complete with a replaceable, factory preset cartridge.
Upchurch Scientific BPR Assemblies create incremental back pressures ranging from 5 to 1000 psi (0.3 to 69 bar). Our Biocompatible BPR Assemblies feature a PEEK holder; polymer-based fittings; and our biocompatible BPR cartridges (manufactured from inert polymers and gold-plated stainless steel components). Our Stainless Steel BPR Assemblies feature the same biocompatible BPR cartridges with a 316 stainless steel holder and polymer fittings."

• Prevent System Over-Pressurization

Upchurch Scientific Pressure Relief Valves are ideal for preventing system over-pressurization. These products protect system components by diverting fluid flow automatically when pressure exceeds the set limit. Choose between our preset 100 psi (7 bar) and 5 psi (0.3 bar) assemblies, both shipped with our Flangeless Fittings. The 100 psi version is a good, general purpose valve, while the 5 psi version is perfect for protecting syringe and peristaltic pump systems. The void volume of both relief valves is low due to the small 0.020"" (0.50 mm) thru-holes in the valve tee body.
If you wish to have the Pressure Relief Valve open at a different pressure than 5 or 100 psi, simply combine one of the other replacement Back Pressure Regulator Assemblies with the P-612 Pressure Relief Valve Tee. Choose the P-612S for larger bore tubing and higher flow applications."

• Nonmetallic and Biocompatible
• Low Cracking Pressure of 1 psi (0.07 bar)
• Excellent Chemical Resistance

Upchurch Scientific® Inline Check Valves provide excellent backflow protection for sensitive equipment along with outstanding chemical resistance only available from PEEK polymer and perfluoroelastomer. Metal-free composition makes these check valves perfect for use with corrosive fluids or biological samples.
These check valves function well in both low and high pressure applications. Low internal volume also allows them to be used in areas where flow path volume is important; however, higher flow rates can pass through with minimal pressure drop. All six Nonmetallic Inline Check Valves have a 0.020"" thru-hole [We also offer 0.040"" and 0.060"" thru-hole versions of CV-3320 and CV-3321 (CV-3322, CV-3324, CV-3323 and CV-3325, respectively)]. All six also feature a springless design with 1 psi (0.07 bar) cracking pressure.
Direct-connect the CV-3320 or CV-3321 to any 1/4-28 flat-bottom port for trouble-free back flow protection. If you are using a pump after your analytical column, consider placing a CV-3330 Check Valve after the column to prevent fluid from the post-column pump from flowing backwards through the column. This product also serves as an excellent nonmetallic alternative to our CV-3010 in sparging applications where the mobile phase may be corrosive to the stainless steel or ethylene propylene components inside the CV-3010 assembly.
The configuration of the CV-3335 Inlet and CV-3336 Outlet Check Valves allows tubing larger than 1/16"" OD (up to 1/8"") to be connected into a 10-32 coned internal port. Use both of these check valves when attaching a larger-volume sample loop to an analytical-scale injection valve. This setup limits the flow of the sample into the loop to one direction, minimizing back flow and sample carry-over. The CV-3340 is useful in virtually any high pressure fluid pathway using 1/16"" or smaller OD tubing, where limiting the direction of flow is desirable.
The Nonmetallic Inline Check Valves with 1/4-28 flat bottom internal ports can accommodate 1/32"", 1/16"", 1/8"" and metric (1.0 - 3.0 mm) OD tubing, depending on the fittings used. Select from the broad line of Upchurch Scientific Flangeless, Super Flangeless and VacuTight fittings.
The Nonmetallic Inline Check Valves with 10-32 coned internal ports are compatible with standard 10-32 threaded polymer Fingertight and SealTight Fittings - metal fittings are not recommended as they may damage the ports. These ports can also accommodate NanoTight Fittings and Tubing Sleeves to connect capillary tubing.

In addition, the unique design of this product eliminates the additional tubing cuts and connections required to install conventional inline check valves.
At a low cracking pressure of only 3 psi (0.21 bar), our CV-3315 and CV-3316 Check Valves are well suited for syringe-pump and vacuum systems. The cracking pressure of our CV-3301 and CV-3302 Check Valves is 15 psi (1.0 bar). All four of these valves are constructed of materials offering excellent chemical resistance: PEEK, Kel-F®, PTFE (CV-3301 and CV-3302 only), stainless steel or gold-plated stainless steel springs, and perfluoroelastomer.

Upchurch Scientific® cartridge - style Inline Check Valves are designed to limit flow to one direction. These assemblies withstand system pressures of 1000 psi (69 bar). If the accompanying Flangeless Fittings are replaced with Super Flangeless Fittings, the Check Valve Assemblies will hold to higher pressures in the reverse direction. [These Inline Check Valve Assemblies should not be subjected to pressures above 3000 psi (207 bar)]. If you prefer Fingertight Fittings, try an Inline Check Valve Cartridge with the U-469 Stainless Steel High Pressure Holder.
Try our CV-3010 Assembly and CV-3011 Cartridge, designed specifically for degassing (sparging) lines to prevent solvent backup if the sparging gas runs out. This check valve will help prevent potential solvent cross-contamination and damage to the gas regulating valve.

• For Interfacing LC-MS Systems
• Adjustable Split Stream Flow Rates
• Medium and High Pressure Versions

Upchurch Scientific® offers a line of Micro-Splitter Valves designed to accurately split and control a low-flow stream off a single incoming supply.
The biocompatible Medium Pressure Micro-Splitter Valves are perfect for LC-MS and other multidetector systems and fraction collectors. The ideal placement of these valves is on the effluent side of the detector flow cell, at a maximum pressure of 800 psi (55 bar). Choose between 1/4-28 and 10-32 threaded versions. A valve is also available to accommodate applications involving capillary tubing.
The High Pressure Micro-Splitter Valves are designed to operate successfully up to 4,000 psi (276 bar). These products are well suited for running two analytical devices in parallel. The High Pressure Capillary Micro-Splitter Valves may also be used to adapt an analytical HPLC system to handle microbore applications.
Our Graduated Valves offer many of the benefits and features of our original Micro-Splitter Valves, plus the ability to adjust and set the split flow to repeatable settings. This allows documentation of settings and the resulting flow rates for easier method development. The graduations also make it easier to employ the valve in a system used to run multiple analyses that require different split flow rates. Choose from regular High Pressure and Capillary versions.
All Micro-Splitter Valves have been tested at flow rates to 100 mL/min., with a maximum resulting pressure drop of only 45 psi (3.1 bar).
Micro-Splitter Valve Applications & Notes
Back Pressure Considerations
Our Micro-Splitter Valves are designed to work when both effluent flow path pressures are nearly identical. However, the split flow path will often have higher back pressure than the waste flow path, making it hard to achieve any split flow at all. There are two possible solutions. Place a back pressure regulator on the waste flow path that is equal to or slightly greater than the pressure on the split flow path. Or, switch the two effluent pathways such that the split flow pathway is attached to the ""waste"" port on the valve and the waste flow pathway is attached to the ""split"" port on the valve.
Prime/Purge Valve
Air within the pump head can cause noisy pump operation and flow instability. Solve this problem by placing a High Pressure Micro-Splitter Valve or High Pressure Universal Prime/Purge Valve inline between the pump and the injector valve. You can then safely divert pump flow to a waste container at a sufficient rate to dislodge the air. Remove air from the solvent line leading to the pump with a Low Pressure Prime/Purge Valve.

• Nonmetallic and Biocompatible
• Low Cracking Pressure of 1 psi (0.07 bar)
• Excellent Chemical Resistance

Upchurch Scientific® Inline Check Valves provide excellent backflow protection for sensitive equipment along with outstanding chemical resistance only available from PEEK polymer and perfluoroelastomer. Metal-free composition makes these check valves perfect for use with corrosive fluids or biological samples.
These check valves function well in both low and high pressure applications. Low internal volume also allows them to be used in areas where flow path volume is important; however, higher flow rates can pass through with minimal pressure drop. All six Nonmetallic Inline Check Valves have a 0.020"" thru-hole [We also offer 0.040"" and 0.060"" thru-hole versions of CV-3320 and CV-3321 (CV-3322, CV-3324, CV-3323 and CV-3325, respectively)]. All six also feature a springless design with 1 psi (0.07 bar) cracking pressure.
Direct-connect the CV-3320 or CV-3321 to any 1/4-28 flat-bottom port for trouble-free back flow protection. If you are using a pump after your analytical column, consider placing a CV-3330 Check Valve after the column to prevent fluid from the post-column pump from flowing backwards through the column. This product also serves as an excellent nonmetallic alternative to our CV-3010 in sparging applications where the mobile phase may be corrosive to the stainless steel or ethylene propylene components inside the CV-3010 assembly.
The configuration of the CV-3335 Inlet and CV-3336 Outlet Check Valves allows tubing larger than 1/16"" OD (up to 1/8"") to be connected into a 10-32 coned internal port. Use both of these check valves when attaching a larger-volume sample loop to an analytical-scale injection valve. This setup limits the flow of the sample into the loop to one direction, minimizing back flow and sample carry-over. The CV-3340 is useful in virtually any high pressure fluid pathway using 1/16"" or smaller OD tubing, where limiting the direction of flow is desirable.
The Nonmetallic Inline Check Valves with 1/4-28 flat bottom internal ports can accommodate 1/32"", 1/16"", 1/8"" and metric (1.0 - 3.0 mm) OD tubing, depending on the fittings used. Select from the broad line of Upchurch Scientific Flangeless, Super Flangeless and VacuTight fittings.
The Nonmetallic Inline Check Valves with 10-32 coned internal ports are compatible with standard 10-32 threaded polymer Fingertight and SealTight Fittings - metal fittings are not recommended as they may damage the ports. These ports can also accommodate NanoTight Fittings and Tubing Sleeves to connect capillary tubing.
Tighten check valves with external threads into the appropriate receiving port using a 9/16"" wrench (1/4 turn past finger tight) before connecting tubing and fittings into the internally threaded end."

• Prevent System Over-Pressurization

Upchurch Scientific Pressure Relief Valves are ideal for preventing system over-pressurization. These products protect system components by diverting fluid flow automatically when pressure exceeds the set limit. Choose between our preset 100 psi (7 bar) and 5 psi (0.3 bar) assemblies, both shipped with our Flangeless Fittings. The 100 psi version is a good, general purpose valve, while the 5 psi version is perfect for protecting syringe and peristaltic pump systems. The void volume of both relief valves is low due to the small 0.020"" (0.50 mm) thru-holes in the valve tee body.
If you wish to have the Pressure Relief Valve open at a different pressure than 5 or 100 psi, simply combine one of the other replacement Back Pressure Regulator Assemblies with the P-612 Pressure Relief Valve Tee. Choose the P-612S for larger bore tubing and higher flow applications."

"Reduce odors from solvent waste containers by installing a VaplockTM carbon filter, which may be adapted to a number of low pressure emission sources. Dispose of spent cartridges in accordance with local safety codes."

"Evaporation control units contain check valves that reduce the flow of vapor in and out of a solvent supply bottle. During a system run, as liquid solvent travels out of the supply bottle to the system, air must enter the bottle to displace the solvent removed. DV-115 and DV-201allow air to enter the bottle, but not to escape. Part numbers DV-118 and DV-202 operate in the reverse, allowing pressure relief. DV-201 and DV-202 are constructed of PEEK and perfluoroelastomer and are our most chemically resistant option, while DV-115 and DV-118 are constructed from PTFE with Viton seals."
