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

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® Pro automatically dilutes in seconds a solid sample with the appropriate weight of diluent with traceability. With its robotic arm and high speed process, it offers an efficient and traceable solution for the dilution process of microbiological analyses.

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: 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: 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: ROBU GLASFILTER

ROBU® Filter Crucibles with integrated VitraPOR® filter provide efficient filtration for laboratory applications. Made from durable materials, these crucibles are designed for high-performance filtration, offering reliable separation of solids and liquids. Ideal for gravimetric analysis and other precise filtration processes.

Supplier: THERMO FISHER DIAGNOSTICS

ReadyBags™ are designed for use in food testing by laboratories with large numbers of samples requiring large volumes of broth media or diluent. Each ReadyBag™ contains 3 liters and is intended for use with an automatic dispenser. The ReadyBag™ is connected to tubing for standard laboratory equipment, such as gravimetric diluters or peristaltic pumps, by means of a connector. Connectors are available in two formats: autoclavable, re-usable stainless steel connectors or sterile, plastic, single-use connectors.

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: MILLIPORE

MF-Millipore™ filters without Triton® surfactant contain minimum amounts of wetting agent and have a lower water extractable content than standard MF-Millipore™ filters.

Pipetting accuracy is critical for successful experiments: A small inaccuracy in pipetting can result in important variations in results. The pipette check function of these touchscreen balances allows the user to check if the pipette is still accurate, as per directive ISO 8655 'Piston-operated volumetric apparatus - Gravimetric methods for the determination of measurement error' and customisable methods.

Supplier: Sartorius

These qualitative filter papers are essentially used for analytical purposes and routine analyses, whenever no gravimetric analyses are required. They are wet-strengthened and can be used for pressure and vacuum filtration. They are made of refined pulp and linters with an >95% alpha-cellulose content, are very pure with an ash content <0,1%.

Supplier: MILLIPORE

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: MACHEREY-NAGEL

These quantitative filter papers are made from refined pulp and linters. They are purified in a highly developed clean-up process to remove organic and inorganic impurities. This ensures a low ash content of <0,01 %. They are consistent performance and give safe results in gravimetric analyses.

Supplier: Ahlstrom-Munksjö

Ahlstrom-Munksjö manufactures a series of extremely high purity, acid washed filter papers designed for use in analytical and gravimetric analysis. The quantitative grades are manufactured from top quality cotton linters using ultra-pure, deionised water and are further treated with dilute acid to remove any remaining organic and inorganic impurities. All quantitative grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter.
