Funnels

LABSOLUTE® short-stem funnels are made of high-quality borosilicate glass 3.3. They can also be used to decant and filter hot liquids. LABSOLUTE® funnels with diameter from 35 - 150 mm fit to almost every application. All funnels are manufactured on the basis of ISO 4798.

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® 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® 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.

With short stem. With a cone angle of 60° offers an optimum fit for all filter sizes. Ideal for easy filling of laboratory bottles and filtration of liquids. High temperature and chemical resistance.

Made of transparent polypropylene. Ideal for easy filling of laboratory bottles and filtration of liquids.

• Good temperature and chemical resistance
• Autoclavable at 121 °C and 1.1 bar for 30 minutes

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.

These funnel holders are suitable to hold all types of funnels with a diameter up to 150mm. They can also accommodate separating funnels (up to 1000ml). With or without bosshead.
