47 mm Filter Holder
GVS offers a selection of filtration holders and apparatus that are designed to ensure precise filtration work with GVS membranes.
In most applications, the filter holder is just as important as the filter for accurate results every time. Filter holders are available for a wide variety of applications including air analysis, chemotaxis, tissue culturing and general aqueous and solvent filtration.
Available products are: 13, 25, and 47 mm Filter Holder, and 47 mm Gravi-Seal.
The GVS polypropylene 47 mm filter holder is designed especially for ultra cleaning and sterilizing liquids under positive pressure. In addition this holder can be used for aseptic sampling of liquids or gases at point-of-use or when samples must be collected and processed on-site.
The polypropylene material allows these holders to be used over a wide temperature range with excellent chemical compatibility.
Sealing is achieved by simple hand tightening of the locking ring.
The 47 mm In-Line holder has dual support screens, which allow for flow in either direction. The inlet cap design and exterior locking ring allow the unit to be assembled quickly and efficiently without tearing the membrane. 3 O-rings help to prevent leaks with all membranes.
The 47 mm can filter up to 1 liter depending upon the viscosity of the sample. The polypropylene holder can withstand temperatures up to 121°C and be autoclaved.
