Description
Pellet burette 10 ml class AS with Schellbach stripe is a precision titration instrument designed for rapid, reliable volumetric work in analytical laboratories. Graduated 10 ml with 0,02 ml divisions, it meets class AS tolerances and is conformity-certified to ISO 385. The unit incorporates an NS intermediate stopcock together with a lateral valve stopcock fitted with a PTFE spindle, enabling smooth, controlled delivery without a pressure ball. A Schellbach stripe runs the length of the burette tube to sharpen meniscus reading and reduce parallax error during endpoint determination. Supplied complete with a 2 l reservoir bottle, the assembly supports continuous reagent feed for serial titrations. Manufactured by Witeg, this pellet-style burette is intended for routine acid–base, redox and complexometric procedures where class AS accuracy and clear readability are required. The compact configuration suits both teaching and quality-control environments that demand repeatable dispensing from a dedicated stock bottle. Pack size is 2 pc(s).

Questions about Autom. burettes, Pellet, class AS, 10 ml
What is this article?
Autom. burettes, Pellet, class AS, 10 ml 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.
