DURAN^® borosilicate glass. Modified, with NS 14.5/23 cone for direct mounting onto apparatus assemblies, screw neck and cap for filling with oil and tubing connector.

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

In accordance with Drechsel. Ground joint 29/32. DIN 12463. Flask height 200 mm, working height 250 mm.

With 230 V/60 Hz/16 A/3,2 kW (max.), on / off relay and coolant water sensor made of 3.3 borosilicate glass with dual platinum electrode. Switches connected apparatus (e.g. a heater for a solvent distillation system) off permanently if it detects a shortage of cooling water. An optical and acoustic alarm signal is emitted simultaneously. The relay is connected to the power supply cable of the electrical device and the sensor is connected into the outlet line of the cooling water (10 mm bore tubing connectors are provided). Switch cable length: 5 metres.
Note: Supplied without the stand and accessories shown.

Solvent circulation apparatus, long form with Dimroth condenser made from stainless steel, cone NS 29/32, cone NS 29/32, socket NS 29/32, PTFE-valve 0 to 3 mm , vapor tube outside, borosilicate glass 3.3.
Type 1: with double oblique bore stopcock, PTFE-plug NS 18.8/6.0 mm bore, with hose connection 8 mm.
Type 2: with 2-way PTFE valve with fine thread for return flow and removal.

Enables effective cleaning of chemicals and substances that turn from solids to vapours directly without liquidifying first and solidifying again on cooling. The cleaned sublimate can be fully recovered from the conical cooler without difficulty once the sublimation process is complete.
