Vacuum Filtration

For Volumes < 50 mL

Sample Preparation
96-well filter plates for sample isolation and purification
At every stage of the drug discovery process samples must be isolated, purified and prepared prior to testing. In today's fast paced environment, rapid, automated and simple sample preparation is a must. MultiScreen plates offer diverse and versatile formats for a variety of preparative methods.

Glass Microanalysis Filter Holders
For 25 mm disc filters
Use to vacuum filter small volumes of liquids for particulate or biological contamination analysis. Filter support is available in fritted glass or stainless steel. Thick prefilters or laminated filters will not seal in this holder. Durapore (PVDF) or unlaminated PTFE are recommended for solvent applications.

Sterifil® Aseptic System and Holder
For 47 mm disc filters
Used for general filtration applications and filtration of samples for particulate or biological contamination analysis. The closed unit protects sample and filtrate from environmental contamination. Sterifil holder and funnel available separately (without receiver flask and cover) to use with standard 1 L vacuum filtering flask or multiple place manifold.

Stericup™ Filter Units
Vacuum-driven filtration and storage devices
The Stericup vacuum filtration system combines a Steritop filter unit with a receiver flask for processing and storing volumes from 150 mL to 1,000 mL. Its new no tip/easy grip flask design and compact profile improve stability during filtration, make gripping the receiver easier, and make the Stericup ideal for use in laminar flow hoods.

Steritop™ Filter Units
Vacuum-driven bottle-top devices
Steritop bottle top filter units provide a large filter area for rapid sterile filtration of aqueous fluids into narrow-mouth (33 mm) or wide-mouth (45 mm) bottles. A small tab inside the funnel secures an optional prefilter in-place during filtration. For added protection against contamination, the threads for bottle attachment have been slightly recessed in case the funnel accidentally touches a work surface.
