Automatic Burettes

Automatic Burettes These burettes have easy to read blue graduations against a white background. The delivery end is fitted into a plastic push button stopcock which permits drop by drop delivery. A small screw clamp presets drop speed for repeat titration. A polyethylene filling tube extends from the top of the burette into the bottle reservoir. Bottle, screw cap, and round base are polyethylene. Graduation accuracy is Class B. Plastic-coated burette 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 stopcock of the burette is made of high quality plastic. Its PTFE plug turns easily and allows fine titration. available in the following variants: - cap. 25 ml/ o.05 ml, tolerance + / - 0.05 ml, cap. bottle 1000 ml cat. 106599 - cap. 50 ml/ 0.10 ml, tolerance + / - 0.10 ml, cap. bottle 1000 ml cat. 106699 Special protection against breakage if the symbiotic gets knocked over: -The temperature-resilient plastic coating helps the entire device to resist breakage and glass fragments are confined within the sheath. -A small bumper has been attached to the upper end of the upright measuring tube. This feature reduces the change of breakage.
