Sartorius 16309 is the all glass vacuum filter holder, appropriate for membrane filters with a dia. of 50 mm (or 47 mm). The 16309 come complete with vacuum-resistant glass flasks, that can be utilized to retain the filtration.
A 6 mm wide, non-ground glassy rim, located above the ground glassy neck of the filtrating flask, prevents contamination of the filtrates by contact with the ground glassy area (e.g., by grease) while it is being poured out. The filter supports consist of a glassy frit in a PTFE ring. All other parts of the holders that come in contact with filtrating medium are made of glassworks.
The glassy funnel and the base are held together securely by a metal clamp. A centering rim on the filter support makes it easy to position the funnel and prevents the inserted/infused membrane filters from being displaced.
The device is ideal for analytical determinations, degassing and particle removal from solvents.
