Gravimetric Dilutor, Jumbo kit

Supplier: VWR Collection

Gravimetric dilutors are used for the dilution of a sample before microbiological analysis.

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.

DiluFlow® is a gravimetric dilutor for the dilution of the sample before its microbiological analysis.

Supplier: IUL Instruments SA

Equipment specifically designed to facilitate the controlled addition of media into a homogeniser/lab blender bag using a load cell. The Pinch Dilutor constantly monitors the weight in the homogeniser bag and consequently distributes the precise quantity of diluent into the bag.

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: 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: 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.

Supplier: VWR Chemicals

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: MACHEREY-NAGEL

MN 85/70 BF is the binder free alternative to MN 85/70. Suitable for gravimetric analysis with heat stability up to 500 °C.

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: ROBU GLASFILTER
