The Amerlex-M system is a magnetic separation system for use in immunoassay. It combines the advantages of second antibody solid phase separation with liquid phase kinetics. Its use eliminates centrifugation during the separation of free and bound ligand. Amerlex-M donkey anti-rabbit reagent consists of magnetisable polymer beads coated with second antibody. The use of this reagent enables phase separation by introduction of a magnetic field. It is used where the primary antibody is of rabbit origin and is particularly suitable for iodine-125 radioimmunoassays as bound counts end up in the pellet.

AdvanceBio Glycan Mapping Columns for fast, reproducible, high resolution glycan characterisation.

Supplier: HAMILTON BONADUZ

This anion column line is designed to meet the special requirements of anion analysis. These four columns cover all aspects of standard anion analysis, separation of all 8 common anions in one run. The unique design of the highly cross-linked porous-packing material, and the strong covalent bonded surface chemistry, ensure excellent durability and high separation efficiency. These columns are designed to be used with carbonate-bicarbonate buffer in any concentration or with hydroxide gradient, and many other mobile phases.

XPert™ balance enclosures provide user protection by keeping powders, particulates and fume contained during weighing procedures. They are well suited for pharmaceutical research and other laboratory applications involving weighing of toxic substances. These vented balance safety enclosures may be ducted to the outside or connected to the FilterMate Portable Exhauster to be exhausted back into the laboratory through HEPA filters, carbon filters, or a combination of both HEPA and carbon filters.

TSKgel® SW size exclusion columns are widely used for aqueous analysis and isolation of proteins, antibodies, enzymes, nucleic acids and other biological macromolecules.

Supplier: LABCONCO

These portable systems provide user protection by keeping powders and particulates contained during weighing procedures. The built-in blower and HEPA filter are mounted in the upper plenum to save space, and the enclosures have low installation costs and require no outside ducting. Systems also provide quiet operation as low as 45 dBA, depending on face velocity.

Supplier: VWR Collection

Semi-micro balances with resolution of 0,01 mg and a built-in ioniser, which ensures accurate sample preparation. Static charges accumulate in different samples that are routinely weighed in the laboratory. These static charges can build up and alter the weighing value. By blowing ions, the built-in ioniser neutralises static electricity and within seconds the sample is ready to be weighed. The balance calibration system automatically calibrates the balance when there is a temperature change or at a set period of time (factory settings), this ensures accurate measurements even if the user has not manually calibrated the balance. All models have a stainless steel top pan.
