Burettes

The LABSOLUTE® burettes made of borosilicate glass 3.3 comply with DIN EN ISO 385. They are available with straight and lateral stopcock with glass plug or PTFE needle valve. The class AS burettes are a very economic way to get reliable values in volumetric analysis quickly and easily. They are calibrated to "Ex" and have a blue graduation and inscription as well as a Schellbach stripe on the backside to be able to read the meniscus precisely.

The LABSOLUTE® glass keys for burettes made of borosilicate glass 3.3 are compatible with the respective LABSOLUTE® burettes with straight or side stopcock. Delivery includes O-ring and plastic parts.

The automatic LABSOLUTE® burettes according to Dr. Schilling can be used for several applications in many areas, such as electroplating, water treatment or sewage plants. They are impressing through their precise dosing, the possibility of fine titration and an exact draining tip. The class B burettes are justified to "Ex" and come with a LDPE bottle and solid stand. The tolerances comply with DIN EN ISO 385. There is a Schellbach stripe on the backside of the burettes that makes it easier to read the exact filling level. The bottle and the burette are fixed together by the titrating armature.

The burettes are delivered dismantled, but can be easily installed without additional tools.

On request, the burettes can also be offered with a plastic coating for better shatter protection at an extra charge.

The LABSOLUTE® PTFE spindles / PTFE needle valves are compatible with the respective LABSOLUTE® burettes with straight or side stopcock.

Fast flow burette with 500 ml plastic reservoir bottle (up to 10 ml) or 1000 ml (from 15 ml). Schellbach stripe and graduation in high contrast blue enamel.

Burette according to Dr. Schilling with splinter protection, with Schellbach stripes, automatic zero point extraction and Bürkle dosing device. The glass burette is covered with a plastic sheet which increases the tensile strength and serves as splinter protection. The probability that the burette breaks is reduced compared to conventional burettes and even in case the burette breaks, no dangerous splinters will be produced. The dosing device allows precise dosage via the pushbutton or via the micro-screw as well as precise dispensing via a fine spout tip.
