Schellbach Automatic Zero Burettes are each mounted on a graduated reservoir bottle. Solution rises to the top of burette by squeezing the rubber bulb. The burette is automatically set to zero releasing the air pressure from the valve. Unique features of Schellbach design include a vertical white stripe with central blue ribbon to facilitate accurate reading of the meniscus, and an intermediate PTFE stopcock which facilitates the complete drainage of excess liquid back into the reservoir. Both burette and reservoir are made of precisely-bore, high quality, heavy-duty borosilicate 3.3 glass with excellent durability and chemical resistance. Both Class A and Class B versions conform with DIN ISO 385 standards for accuracy. Calibrated to deliver. All components are packed in custom foam inserts for safe transport and storage.
