Precipitation reagent for Cs and titrimetric reagent for nonionic surfactants

Supplier: Merck

This assay determines the total dietary fiber content of food using a combination of enzymatic and gravimetric methods. Samples of dried, fat-free foods are gelatinised with heat stable α-amylase and then enzymatically digested with protease and amyloglucosidase to remove the protein and starch present in the sample.

Supplier: Whatman products (Cytiva)

Cytiva's Whatman Grade 41 environmental pollution papers are among the fastest filter papers in the Whatman ashless range. This gravimetric filter is well suited for quantitative analysis of soil and air.

Supplier: IUL Instruments SA

The Smart Dilutor W automates and facilitates the precise gravimetric dilution of samples, that is a key process stage in microbiology laboratories.The system incorporates a peristaltic pump linked with a load cell to rapidly and accurately dilute the sample to a preset dilution factor. The sample bag, typically a pre-sterilised 400 ml blender bag is attached to a bag holder which effectively serves as the weighing platform, making the process simple to operate, disassemble and clean.

Supplier: Merck

The filters without binder resin retain their structural integrity without weight loss when heated up to 500 °C and can therefore be used in gravimetric analysis as well as for the filtration of hot gases.

Supplier: INTERSCIENCE

Gravimetric dilutor, Printer

Supplier: LGC Standards PROMOCHEM

These standards are intended for use in the determination of fuel (diesel fuel or gasoline) in used engine oils by GC, IR, fuel dilution meter (fuel sniffer), or flash point analyser. They are prepared gravimetrically from well-characterised fuels and hydrocarbon oils, and are verified by GC-FID in accordance with ASTM Method D3524 or D3525.

Supplier: Whatman products (Cytiva)

These filter papers made from high quality cotton linters have the finest retention of all ashless filter paper grades. Grade 42 is designed for gravimetric analysis and sample preparation for instrumental analysis.

Supplier: Whatman products (Cytiva)

Cytiva's Whatman Grade 43 filters support inorganic analysis and other forms of instrumental analyses. The low ash content also makes Grade 43 appropriate for gravimetric analyses requiring sample combustion.

Supplier: Whatman products (Cytiva)

Cytiva's Whatman Grade 540 is a high-purity, acid-treated cellulose lab filter paper. Mechanically strong Grade 540 is well suited for quantitative or gravimetric analysis of strongly acidic or alkaline samples.

Ready to use colour solutions that are prepared gravimetrically on a weight/weight basis that are designed for grading the colour of similarly coloured liquids, such as resins, varnishes, lacquers, drying oils, fatty acids, lecithin's, sunflower and linseed oil.

Supplier: Sartorius

Binder free glass microfibre filters are made of 100% borosilicate, are highly pure and extremely white. They are recommended for analytical and gravimetric analyses and also as prefilters. These filters combine fast flow rates with high load capacity and the retention of very fine particles.

Supplier: bioMérieux

The Dilumat™ series of gravimetric diluters feature a detachable control unit with a modern, user friendly and intuitive interface, that enables remote operation. The EXPERT and EXPERT EVO come with two pumps that can be used in DUAL pump mode (pumps used together on the same broth) but with the possibility of enlarging the operation with up to four external pumps. The Dilumat™ START has a more reduced range of operation and the possibility of only one external pump.
