Burettes

• Manufactured from pre-vacuum calibrated borosilicate glass. They meet the highest quality standards according to DIN EN ISO 385
• Permanent quality control through all steps eliminates possible deviations from nominal values
• Calibrated to deliver (Ex) and the tolerances are according to DIN/ISO Class "AS" standards
• Conformity ("DE-M") certified, with a batch number printed on the body. Batch certificate can be downloaded from the suppliers website
• Supplied with an automatic zeroing system, VALVE stopcock and also an intermediate PTFE stopcock to recirculate the remaining liquid
• Clear burettes are manufactured with schellbach stripe
• Inscriptions and graduations are printed with special blue enamel. For amber burettes, white enamel is used to maximise visibility and durability

Glass bottle - Please order separately.

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 protection
• Adjusted to Ex
• Shatterproof, resistant to chemicals
• Exact spout tip, fine droplet formation
• Parts in contact with the medium: PE, natural rubber, PP, Borosilicate glass

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 divisions
• Conforms to ISO 385
• Autoclavable
• Corresponds to USP / EP and JP guidelines

All BLAUBRAND^® burettes are supplied with batch number and an accompanying batch certificate in the original packaging. On request, they are also available with an individual certificate, USP individual certificate or DAkkS calibration certificate. Batch and individual certificates can also be downloaded at the supplier"s website.

For quickly and reliably titration with highest precision, even in close quarters, with no mains supply needed - in the lab, in production, or in the field! The Titrette^® bottle-top burette has an innovative new measuring system which matches the Class A accuracy of glass burettes and, if needed, can offer the precision of 3 decimal places below 20ml. This is an important feature for users who need to work within the Class A error limits as with glass burettes according to DIN EN ISO 385 (e.g., pharmaceutical work). The titrating tube can be adjusted horizontally and vertically. This provides flexibility when positioning the instrument, e.g., when using a magnetic stirrer or different bottle sizes.

• High accuracy
• Smooth-running operation for sensitive, drop-wise titration and fast filling of the device
• Compact design
• Light and stable, easy handling
• No switching between fill and titrate
• Simple maintenance
• Cleaning and parts replacement right in the lab
• Titrette^® SH to determinate the acid content of milk and liquid dairy according to Soxhlet-Henkel (4 °SH = 1ml)
