Solid Phase Extraction (SPE) Disks

Solid phase extraction (SPE) disks are used commonly in large-volume sample preparation. These disks resemble the membranes used for filtration, but differ in that sorbent particles are embedded in an expanded PTFE network or fiberglass matrix. Solid phase extraction (SPE) disks are flat (usually 1-mm or less in thickness) with diameters ranging from 4 to 96 mm. Generally, the packing material comprises 60 to 90% of the total membrane weight. The small length-to-diameter ratio of and SPE disk enables higher flow rates and faster extractions than can be achieved with cartridges. For example, 1 liter of relatively clean water can pass through a 45-mm SPE disk in approximately 20 minutes, but may require one to two hours when using a 15 mm x 18 mm cartridge bed.

 


Products & Services
Solid phase extraction (SPE) cartridges and discs are used to clean up a sample before using a chromatographic or other analytical method to quantify the amount of analyte(s) in the sample.
Data storage systems are used to store, protect and manage computer data. Many types of disk drives and tape drives are available.
Fillers and reinforcements are additives used to extend, strengthen and/or modify plastics, composites, adhesives, coatings and other materials.
Optical choppers are mechanical or electronic devices that pass and then interrupt a beam of light for a known brief interval.  Optical shutters are used to control the amount of time that a light sensitive material is exposed to radiation. 
Hard drives are integral, non-volatile, electronic data storage units inside computers. Traditionally, hard drives were hard-wired into computers. Removeable hard disks and drives are also available.
