Description
Trapezoidal volumetric flask 1 ml class A TC with NS 7/16 ground joint and PE stopper is a precision laboratory vessel for accurate volumetric measurements. Manufactured from borosilicate glass 3.3, it features brown Diffico markings and is conformity certified. Every flask carries a batch number and is supplied with an accompanying batch certificate per original packaging, ensuring full traceability for quality systems. The trapezoidal body provides excellent bench stability and comfortable handling during solution preparation and dilution work. This model from manufacturer Witeg combines the NS 7/16 joint with a polyethylene stopper to give a secure, contamination-resistant closure. Calibrated to contain (TC) at class A tolerance, the 1 ml capacity supports reliable preparation of standards and quantitative analysis in analytical chemistry, pharmaceutical QC and research laboratories. Borosilicate glass 3.3 offers high resistance to thermal shock and chemical attack. Net weight is 0,008 kg per flask. The flasks are packed in units of 10 pieces, making them practical for routine laboratory supply and multi-user environments that demand reproducible volumetric performance.

Questions about Trapezoidal volumetric flasks 1 ml A CC ST 7/16
What is this article?
Trapezoidal volumetric flasks 1 ml A CC ST 7/16 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
A volumetric flask is calibrated to contain one volume at a reference temperature, with a single mark on a narrow neck. Class A is the tight tolerance. It is not a storage bottle and it is not for heating. The stopper is part of the calibrated article.
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.
