The sterile plastic funnels with 47 mm diameter allow quick performance of the filtrations required in the routine testing of water, food and beverages, pharmaceutical and cosmetic products. A Sartorius Stedim Biotech gridded membrane is placed on a stainless steel filter support and a Microsart^® Funnel is simply and practically fitted on and the sample is filtered by vacuum.

• Click-Fit closure for optimum sealing
• Graduation with markings for exact volume dosing

The stand for sedimentation funnels is used to keep, hold or store Imhoff funnels safely and reliably during sedimentation. Two funnel holders ensure that Imhoff funnels will be held safely and securely and can be placed in an absolutely vertical position. Stand with two holders for sedimentation funnels, suitable for funnels 90 mm or more in diameter. Thanks to an innovative magnet concept no clamping screws are necessary. The height of the funnel holder can be adjusted easily and flexibly with one hand. With the corresponding accessory the holders for Imhoff funnels can also be replaced by holders for all-purpose funnels.

• PP, chrome-plated steel
• Adjustable height up to 450 mm

Dispensing funnel for powdered substances. With cone NS 29/32, NS 29/32 socket, NS 14,5/23 side socket.

Cylindrical shape. With interchangeable PE stopper and stopcock with key as indicated, incl. retaining device.
Graduated for reading the approx. volume.
Two types are available:

• With solid glass key stopcock
• With PTFE key stopcock

This filter funnel, which is designed for normal and low pressure, is made of PTFE and PFA, making it resistant to almost all chemicals. It does not leave any trace elements in the medium to be filtered. The vacuum connection is a multi-stepped tubing ferrule with sealing screw, adjustable to suit the most common vacuum tubing bores (6 and 8 mm). The NS 29/32 socket provides a perfectly tight seal onto a similarly socketed, round-bottom flask made of PTFE, PFA or glass (please note vacuum compatibility). Supplied without membrane filter. Suitable for 47 mm diameter membranes, filter area 13.8 cm², sample funnel volume: 125 ml.
