Description
The DURAN® burette class B, 25:0,05 ml is a clear glass volumetric instrument designed for accurate titration and controlled liquid delivery. Black graduations and fine line division ensure excellent visibility of the meniscus throughout analytical procedures. Constructed from borosilicate glass 3.3, the burette combines mechanical strength with resistance to common laboratory reagents and moderate thermal stress. It features a straight valve stopcock with PTFE spindle for smooth, grease-free operation and dependable sealing. Manufactured to DIN EN ISO 385 requirements, this class B model satisfies standard accuracy limits for routine quantitative work. The 25 ml nominal capacity with 0,05 ml scale intervals enables precise titrant addition in a wide range of analytical methods. Available as a pack of 2 pieces from manufacturer Hirschmann, these burettes fit conventional titration setups in educational, industrial and research laboratories. Their durable clear-glass design supports reliable long-term use under everyday laboratory conditions.

Questions about BURETTES CL. B 25:0,05 ML, STR.VALVE STOPC., PTFE SPINDLE
What is this article?
BURETTES CL. B 25:0,05 ML, STR.VALVE STOPC., PTFE SPINDLE is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
A burette delivers a measured volume through a stopcock, which is how a titration is read. Class A and class AS state the tolerance. The stopcock, glass or PTFE, and the volume of the burette are the choices. A dirty bore changes the delivered volume.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
