Funnels

LABSOLUTE® powder funnels made of transparent PP are unbreakable and very economic. They can be autoclaved at 121 °C. The funnels are suitable to transfer powders, granulated materials and highly viscous liquids. The parallel stem prevents blockage in the funnel. There are also ribs on the inside for fast filtration and ribs on the outside to prevent air blockage.

LABSOLUTE® funnels made of transparent PP are autoclavable at 121 °C. Compared to glass funnels, the shatterproof PP funnels are a good and cheap alternative for almost every filtration of low-viscosity liquids. Standard filter paper fits into the funnels. Ribs on the inside ensure fast filtration. Ribs on the outside avoid air bubbles between the filter paper and the funnel's surface.

LABSOLUTE® funnel holders made of PP are suitable for funnels with a diameter from 25 up to 150 mm. Without adapter they can be used for powder funnels with stem diameters not exceeding 35 mm. A clamp adapter is provided for use with rods from 8 to 12 mm.

Clear, virgin polypropylene, autoclavable at 121°C and 1.1 bar for 30 minutes.
The external ribs prevent airlock and back pressure. The internal helicoidal rib prevents filter papers from sticking and increases filtration speed.

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.
