Funnels

Solid addition funnels (angle: 60°), with NS cone, made of DURAN^® tubing.

With short stem and NS cone.

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
• For funnels with Ø 90 mm or more

PP holder mounted on a stand with 12.7 x 595 mm aluminium rod and heavy cast base plate.
Choice of stands to hold 2 or 4 funnels with a top diameter of 50 to 120 mm. The holder height is adjustable.

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

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.

Rubber Spacers, made of natural rubber (NR). Conical, to fit filter funnels or crucibles into suction flasks. Durometer 40 Shore A

Straight tube outlet.

Borosilicate glass with acrylic support plate for filter paper. Can be dismantled quickly for cleaning. Dimension given is the filter paper size required.

• funnel volume 60 ml
• for filter 25 mm diameter

Designed specifically for analytical chemistry. Each size takes a standard size filter paper. Body of funnel is exactly 60° angle. Provided with external and internal ribs. Autoclavable. Food-safe.

With suspension eyelet. Tough, robust, general purpose funnels suitable for a wide range of liquids. Upstand on rim to reduce possible overflow. Ribbed on outside to eliminate back pressure.

Funnels with smooth surfaces and short stem. 60° angle. DIN 12445.

• For rapid filtration
• Angled at 60°
• External ribs allow air to escape during filtration
• With short, wide stem

Suitable to hold all types of laboratory funnels and also separatory funnels with diameter from 60 up to 150 mm. Two tapered wedges are provided to ensure firm grip.

This compact funnel with lid is optimally suited for restricted space conditions in the laboratory. The hinged lid closes the funnel clean and safely. The removable sieve collects magnetic stirrers and solid substances during fluid discharge.

• With removable sieve for easy cleaning
• Different thread sizes with free rotatable cap
• Safety lance ensures clean outflow without contaminating the container opening
• Lance length: 200 mm
• Also available without safety lance
• Chromatography vials can be disposed completely when the sieve is removed
• Black Safety funnels are made of electrostatic conductive HDPE and have a grounding connection to avoid ignition risks. Grounding cable (1.5 m) and grounding clamp are included

• Funnel diameter: 140 mm

Diameter refers to the filter plates.
