993 8. Liquid Handling Titration/Burettes GENERAL CATALOGUE EDITION 20 E & OE. Automatic burettes, Schilling pattern, borosilicate glass 3.3, PE-LD, class B Made of borosilicate glass 3.3. Class B. Conformity with DIN ISO 384. With Schellbach stripes (blue/white) and easily readable, black scaling. Calibrated to deliver, EX. Automatic zeroing. The burette stopcock is made of high quality plastic. Its PTFE key turns easily and allows fine titration. Special protection against breakage if the apparatus gets knocked over: A small bumper has been attached to the upper end of the upright measuring tube. This feature reduces the chance of breakage.
