These bottle top digital burettes are hand operated. Turning the hand wheel affect the delivery of liquid, the dispensed amount is shown on the display. Small dimensions and a low weight prevent a top-heavy system.

ISO 9001 and the GLP guidelines require routine regular checking (approx. every 3-12 months) and recalibration of measuring instruments. In order to facilitate and simplify this task, the Contiburettes® µ10 C and µ20 C are equipped with a calibration function.
 

Rotating the hand wheel enables these Contiburettes® to deliver dispensed liquid with an accuracy of 0.1%. The volume is displayed in the LCD with a resolution of 10 µl for the Contiburette® µ10 C and 20 µl for the Contiburette® µ20 C. The instruments work without any valves. They are powered by two 1.5 volt AA batteries, which give more than 500 hours continuous operation. Rechargeable batteries may also be used.
Small dimensions and a low weight prevent a top-heavy system. A variety of reservoir adaptors allow for mounting to every laboratory bottle.

All wetted parts are made of Al2O3 and ETFE (Tefzel), both provided with an excellent chemical resistance to almost all liquids in the lab. ISO 9001 and the GLP guidelines require regular checking (approx. every 3-12 months) and recalibration of measuring instruments. In order to facilitate and simplify this task, the Contiburettes® µ10 C and µ20 C are equipped with a calibration function.
