990 8. Liquid Handling Titration/Burettes GENERAL CATALOGUE EDITION 20 E & OE. Burette with straight standard ground stopcock, DURAN ® , class AS 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. From now on the approved DURAN ® burettes are also available with PTFE keys. Unlike the glass keys, the PTFE keys need not be greased, which makes work in the laboratory easier. - Available in three sizes, the right burette for each application - Proven DURAN ® properties - With Schellbach stripe and main graduations as circular divisions - Conforms to ISO 385 - Autoclavable - Corresponds to USP/EP and JP guidelines 1 DURAN Group 1 Capacity Grad.
