Description
Class B burette 5 ml clear glass with lateral valve stopcock and PTFE spindle is engineered for controlled reagent delivery in titration applications. The 5 ml capacity with 0,02 ml graduations allows accurate dispensing of small volumes while the lateral valve stopcock fitted with a PTFE spindle offers smooth, chemically resistant flow adjustment and excellent sealing properties. Clear-glass construction ensures optimal visibility of the liquid column and meniscus. Class B tolerance makes the burette appropriate for routine analytical work, quality control and educational laboratories. The PTFE spindle resists many aggressive chemicals, extending the instrument’s versatility beyond simple aqueous systems. Supplied in packs of 2 pieces from manufacturer Witeg, this burette is well matched to micro-scale titrations and methods that demand fine control of titrant addition. The lateral valve geometry facilitates convenient operation on crowded benches, while the overall glass-and-PTFE design supports straightforward cleaning and long-term reliability under standard laboratory conditions.

Questions about BURETTES, DIN-B,5 ML:0,02 LATERAL NEEDLE
What is this article?
BURETTES, DIN-B,5 ML:0,02 LATERAL NEEDLE is the article on this page. Luminix Health distributes Witeg 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.
