Burettes

• Described as automatic burettes with fast titration and practical usage
• Especially suitable for field analysis where there is a risk of breaking
• The entire system consists of a burette tubing with automatic zeroing system together with a valve stopcock, a reservoir bottle and a bottle stand
• Rapid filling by squeezing the bottle and fast titration by valve stopcock
• Inscriptions and graduations are printed with blue enamel which is specially designed for glass use
• Clear burettes are manufactured with schellbach stripe
• 10 ml burette has a polyethylene reservoir bottle of 500 ml volume whereas 25 and 50 ml burettes are used with bottles of 1000 ml volume

• 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
• With schellbach stripe
• Inscriptions and graduations are printed with special blue enamel

With Schellbach stripe. EX (TD) calibrated. With dated batch identification. Declaration of conformity acc. to DIN 12600. High-contrast blue graduation for easier reading. Main point ring graduation, DIN EN ISO 385. Scale length 500 mm. For those products, batch calibration reports, which are free of charge, can be generated and printed on www.hirschmannlab.com. Additional single calibration reports or DAkkS certificates (former DKD calibration reports) are available.

Silberbrand. Tolerances to class B, DIN EN ISO 385. Borosilicate glass 3.3 burette. PVC filling tube and silicone outlet tubing. LDPE reservoir bottle with HDPE base. Brass / PP micrometer screw. Graduations and inscriptions are in highly contrasting black enamel. With Schellbach stripes. Squeezing of bottle allows rapid filling. Fine titration is easy using the micrometer screw. Coarse titration is achieved by removal of the micrometer screw and using the push button. Calibrated to deliver (EX).

Polypropylene. Bosshead supplied with two adapters so that the clamp can fit on to support rods having diameters 8 to 14mm. Stainless steel spring loaded centre arm holds burette firmly against the two outer arms and is protected by rubber grips. Graduations and meniscus are visible at all times. Suitable for all burettes.

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.
