Millipore® Glass 47mm Vacuum Filter Holder Assemblies

Millipore glass filter holders are designed for bacteriological analysis of water using 47mm sterile membrane filters. These glass filter holders are also ideal for analysis of suspended solids in water using 47mm depth filters. Autoclaving for twenty minutes at 121°C or by a UV sterilizer for two to three minutes is all that's needed for sterile filtration applications. Filter holder assembly includes 300mL borosilicate glass funnel and base, perforated neoprene stopper and an anodized aluminum spring-action clamp. Choose from models with either a fritted glass base or a stainless steel mesh membrane support.
