Andrews Glass is offering 47mm Lab-Crest glass filter holders designed for HPLC, particulate and microbiological contamination filtration.
With discount programmes available for high-volume customers, the filters are suited for small to medium volumes of liquid and are currently being used for a variety of laboratory analyses.
Manufactured in the company's facility, these high-performance filter holders consist of a borosilicate glass funnel (300ml, graduated) and base, with a fused-in coarse porosity fritted support, anodised aluminum clamp and a silicone stopper to fit 1,000ml filter flasks.
Mating surfaces are precisely ground flat to assure a leak-resistant seal.
The glass parts and the clamp are designed to work together to prevent any wrinkling or tearing of the filter membrane.
Lab-Crest glass filter holders are also being offered in 25mm size.
A 47mm base with a stainless-steel screen is available.
All Lab-Crest glass filters can be easily cleaned to prevent cross-contamination.
They are autoclavable; can be sterilised in a UV steriliser or immersed briefly in sulfuric or hydrochloric acid for sanitising.
