LWW 20 water flow monitor
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.

NS-Glass stoppers, hollow borosilicate glass 3.3
Manufactured from borosilicate glass 3.3 which is resistant to heat and almost all chemicals. They meet the highest quality standards according to DIN 12252. Lower closed end of stopper features a "drip-tip" to ensure adhered liquid is returned to the flask. Hexagonal flat head prevents the stopper from rolling and allows stopper to be stood on end preventing contamination of the ground surface.
