Automatic burettes with splinter protection, Schilling pattern, borosilicate glass 3.3
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.With splinter protectionAdjusted to ExShatterproof, resistant to chemicalsExact spout tip, fine droplet formationParts in contact with the medium: PE, natural rubber, PP, Borosilicate glass

Burette with straight standard ground stopcock, DURAN®, class AS, with glass key
The original DURAN® burettes are manufactured from chemically highly resistant borosilicate glass 3.3. Thanks to the precise scale, they are ideal for titration. Calibration is based on the released volume ("Ex") at a + 20°C reference temperature. This means the fluid quantity released can be taken exactly from the scale, as the liquid adhesion to the glass is taken into account in the calibration. Volume content tolerances conform to DIN and ISO accuracy limits.With Schellbach stripe and main graduations as circular divisionsConforms to ISO 385AutoclavableCorresponds to USP / EP and JP guidelines
