Used to filter under vacuum/small volumes for particulate or biological contamination analysis and for general filter application.

Glass components of this unit are manufactured from borosilicate 3.3 glass.

This unit is supplied with a 300 ml graduated funnel, an anodized aluminum clamp, and a 1000 ml flask.

Filter holder, VWR® Base Support with Glass Frit, VWR®

Polysulfone filter holder with funnel can be used with any filtering flask or manifold that accepts a suitable stopper with hole.

Single filter holder accepts Thermo Scientific double open-end prefilters or final filters.

These vacuum operated filter holders feature a glass cylinder, PP base and sealing plug with anodised aluminum closing cap.

These 25 mm in-line filter holders are ideal for liquid or gas filtration.

Use the SolVac® filter holder to remove contaminating particulates and degas mobile phase solvents.

The 13 mm Swinney filter holders are economical for small volume (1 to 10 ml) filtration.

Stainless steel closed filter holder for microbiological, analytical sampling and testing of gas in pressurized lines.

The 47 mm filter holders are designed for in-line liquid or gas filtration. They open and close easily without disturbing the filter disc.

Stainless steel holders are widely used in laboratories for particle removal and for sterile filtration of several liters of volume and can hold filter discs up to a diameter of 142 mm.

These filter holders are designed for microfiltration and ultra cleaning of small volumes of liquids using positive pressure.

Gasket is for use with the VWR* 25mm Filter Holder.

These filter holders are used with Barnstead™ B-Pure™ 1/2 size filters to pre-treat feed water or for a final filter to help ensure consistently pure water.

The open-face filter holders are lightweight and corrosion-resistant.

Polypropylene Base for Glass/polypropylene filter holder

Filter holder, VWR® Glass Base for Stainless Steel Support, VWR®

Syringe Filter Holder made of polysulfone is useful in clarification and sterile filtration of liquids and gases under pressure.

Complete glass filter holder set for particulate contamination analyzes and HPLC solvent filtration.

WPI’s filter holder for particulate absorption measurements is specially designed for field use. It is rugged and portable. It performs as well as a laboratory based spectrophotometer. It can be directly connected to WPI’s line of fiber optic spectrometers and light sources.

Made of transparent polysulfone. Break-resistant and withstands repeated autoclaving (before autoclaving, set cover on filter unit without engaging threads).

300mL graduated glass funnel is for use with the VWR* 47mm Filter Holders, Standard Taper (26316-724, -728) and VWR 47mm Filter Holders, Number 8 Stopper (26316-708, -718).

High-quality, corrosion-resistant in-line filter holder is designed for stack sampling.

This all-glass filter holder is used in particulate contamination analysis for filtering aqueous, organic, or corrosive liquids. It is also recommended for HPLC solvent filtration.

Designed for bacteriological analysis where it is necessary to sterilize the filter holder with the membrane filter in place. The glass surface is coated with PTFE to avoid filter damage and membrane adhesion during autoclaving.

High quality, corrosion-resistant holders for stack sampling. Stainless steel construction offers excellent chemical resistance. Holder opens and closes easily. Filter remains undisturbed for particulate analysis.

The disc filter holders are durable and of convenient size for filtration of virtually all laboratory samples.

These syringe filter holders are made from stainless steel. The holders with Luer lock fittings connected to a standard syringe offer quick and easy clarification, sterilisation and removal of particulates from small volume samples, typically for HPLC applications.
