Flow cytometers use laser beams to characterize single cells as they pass by at high speed.
Gas chromatographs separate organic chemical mixtures according to physical properties.
Gas generation equipment provides an onsite supply of gas, vapor, or humidity (water vapor). It eliminates the need for delivery in gas cylinders, which can be bulky and may have special storage requirements.
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.
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, instruments and supplies are used to separate macromolecules, either nucleic acids or proteins, on the basis of size, electric charge, and other physical properties.
Gloveboxes and isolators are used to contain hazardous substances or materials that must not come in contact with the outside environment.
Heating mantles are used to heat flasks containing a sample.
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.
Hot plates are used for heating samples and are used as an alternative to a Bunsen burner when an open flame would be dangerous. Hot plate stirrers are used to mix samples, with or without the application of heat.
High performance liquid chromatography (HPLC) columns use a liquid mobile phase to separate the components of a mixture.
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.
Incubators are used in biological experiments to allow growth of organisms in optimal conditions of temperature, carbon dioxide and humidity.
Industrial adhesives consist of hot melt adhesives, epoxy adhesives, polyurethane adhesives, sealants, thermoset adhesives, UV curing adhesives, silicon adhesives, acrylic adhesives and other related industrial products.
Industrial dyes are colorants consisting of single molecules that are able to absorb certain parts of the spectrum of visible light and reflect others. Dyes are soluble in the material in which they are dispersed.
Inorganic chemicals, inorganic salts and inorganic compounds are substances of mineral origin that do not contain carbon in their molecular structure.
Laboratory air handling equipment is used to protect specimens and laboratory staff from environmental contamination. Products include fume hoods, biological safety cabinets, environmentally controlled rooms and clean benches.
Laboratory balances are used to measure an object’s mass to a very high degree of precision.
Laboratory centrifuges are used to separate particles from a solution according to their size, shape, density, and viscosity of the medium and rotor speed.
Dispensers feed measured amounts of materials, either manually or automatically. The most common types of dispensers are bottle top and burette.
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 fume hoods are partially enclosed workspaces that are exhausted to the outside.
Laboratory furnaces provide continuous heating to process samples and materials.
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.
