Processes and instruments used to prepare and analyze wet chemical samples in a laboratory.
Sample Preparation and Liquid Handling Categories

Autosamplers

Autosamplers are automated sample loaders, usually robotic, used with chromatography and other analytical technologies.

Capillary Electrophoresis Equipment

Capillary electrophoresis (CE) is a family of related separation techniques that use narrow-bore fused-silica capillaries to separate a complex array of large and small molecules.

Desiccators

Desiccators are enclosures used for preserving moisture-sensitive items.

Digesters

Digesters are used to break samples down into their basic constituents for further analysis.

Diluters

Diluters are used to dilute samples to standard concentration ratios.

Gas Chromatographs

Gas chromatographs separate organic chemical mixtures according to physical properties.

GC Columns

Gas chromatography columns (GC columns) are of two types: packed and capillary. Solutes to be measured travel through the column at a rate primarily determined by their physical properties, and the temperature and composition of the column.

GC Detectors

Gas chromatography detectors (GC detectors) identify solutes as they exit the chromatographic column. A chromatogram is generated plotting the signal versus time.

Gel Electrophoresis Equipment

Gel electrophoresis equipment, instruments and supplies are used to separate macromolecules, either nucleic acids or proteins, on the basis of size, electric charge, and other physical properties.

High Performance Liquid Chromatographs (HPLC)

High performance liquid chromatographs (HPLC) use a liquid mobile phase to separate the components of a mixture. The components are dissolved in a solvent and forced to flow through a chromatographic column under high pressure.

HPLC Columns

High performance liquid chromatography (HPLC) columns use a liquid mobile phase to separate the components of a mixture.

HPLC Detectors

High performance liquid chromatograph (HPLC) detectors pass a beam of light through a column effluent as the fluid passes through a low-volume flow cell. Variations in light intensity are recorded and a chromatograph is generated.

Laboratory Balances

Laboratory balances are used to measure an object’s mass to a very high degree of precision.

Laboratory Centrifuges

Laboratory centrifuges are used to separate particles from a solution according to their size, shape, density, and viscosity of the medium and rotor speed.

Laboratory Degassers

Laboratory degassers are used to filter or remove gases from solvents and samples.

Laboratory Dispensers

Dispensers feed measured amounts of materials, either manually or automatically. The most common types of dispensers are bottle top and burette.

Laboratory Filters

Laboratory filters are used to remove particulates from samples in laboratory-scale applications. They consist of a filter medium and housing or holder that constrains and supports the filter media in the sample’s path.

Laboratory Freeze Dryers

Laboratory freeze dryers preserve samples by freezing the material and then allowing sublimation to occur. This water-removal process is also known as lyophilization.

Laboratory Homogenizers

Laboratory homogenizers are high-speed, high-shear mixers that reduce samples to uniformed-sized molecules through maceration, cutting, and blending. They are used to process liquids, slurries, or granular substances.

Laboratory Mixers

Laboratory mixers are used to mix, emulsify, homogenize, disintegrate and dissolve samples.

Laboratory Reactors

Laboratory reactors are used to grow cells and contain reactions. They are designed for small-scale experiments in fields such as kinetics and yield studies. This product area includes shake flasks, small bioreactors, and other products that can be used to complete a preliminary economic evaluation.

Laboratory Shakers

Laboratory shakers and rotators are used to blend or agitate samples within flasks or tubes. These devices consist of a housing containing the motor and control panels, upon which an agitation platform is attached.

Pipettes and Tips

Pipettes and tips are used to deliver a known quantity of solution to a vessel. They are either of the classical style (glass) or digital.

Sample Dryers

Sample dryers are used to remove liquids from a sample through techniques such as freeze drying, spray drying, and evaporation.

Solid Phase Extraction Cartridges and Disks

Solid phase extraction (SPE) cartridges and disks 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.

Solvent Extractors

Solvent Extractors use carbon dioxide or water in a supercritical fluid state to dissolve and extract materials.

Sonicators

Sonicators apply sound energy, (usually ultrasound) to agitate particles from a sample for multiple purposes. Other names for Sonicators are Ultrasonic Processors, Ultrasonic Sonicators, Cell Disrupter, Ultrasonic Homogenizer, Sonifier.

Syringes and Needles

Syringes utilize a cylinder and plunger for precise delivery of liquids or gases in analytical, medical, pharmaceutical or biotechnology applications. Many times needles are included with the syringe.

Titration Instruments

Titration instruments are used to determine the concentration of dissolved substances. Titration is based on a complete chemical reaction between the specific substance, the analyte, and a reagent or titrant of known concentration that is added to the sample.

Vacuum Chambers and Components

Vacuum chambers and components are specialized vessels that can maintain a high vacuum process environment for manufacturing thin films, microelectronics, optics and materials.
