Filtering & Dispensers

MinisartNML 0.2um, 28mm FX eo-ster, 50pc

Wet-strengthened filter papers are manufactured from a majority of alpha-cellulose. The smooth surface allows for fibre free filtration. They feature a high wet strength and can also be used in the filtration of strong alkaline or acid solutions. Due to their high mechanical strength, they are suited to applications where the residue is removed from the filter, for example with a spatula or a jet of water.

What is Grade 304? This grade covers a wide range of laboratory applications and is used for clarifying liquids and for the rapid filtration of coarser precipitates such as lead sulfate, lead chromate, calcium oxalate, calcium carbonate, aluminum phosphate, barium carbonate and beryllium hydroxide.

Grade 304 can be found in soil analysis, seed testing and in air pollution to collect dust-laden air and is also commonly used in the food industry to separate foodstuffs from associated extracting liquid.

Grade 352 high purity filters from Johnson Test Papers are general-purpose papers for quantitative analysis. This grade has medium flow rate and good particle retention and is the most commonly used acid-washed filter. High-purity filters support accurate analysis in applications sensitive to very low levels of background contamination and in gravimetric analysis where ash content might affect weight measurements of combusted samples.

GVS Mixed Cellulose Esters (MCE) Filtration Membrane is an unsupported, hydrophilic membrane. Its rapid flow rate and high throughput make it ideal for use in bioburden and sterility testing.

GVS MCE Filtration Membranes are composed of a mixture of inert cellulose nitrate and cellulose acetate polymers. The uniform microporous structure of these filters provides the fastest flow rates and highest throughputs available in a membrane filter. They are hydrophilic with a noncytotoxic wetting agent and yield extractable levels of less than 4% of their weight. These membranes are autoclavable at 121∞C (250∞F) for 20 minutes. Sterilised product lifetime is 24 months from sterilisation date.

High flow rate: fast filtration rates

Uniform pore structure: consistent flow and diffusion rates
