Product Code : EL-VF-10276
Lab Glassware Manufacturer manufactures and exports the Volumetric Flasks Clear Glass with PE Stopper, Class-B from its production facility in Ambala, Haryana, for routine volumetric measurement in laboratories in India and to export buyers that have recently included Togo, Benin and Ghana — part of a wider base of enquiries from across West Africa.
Quick answer: This is a Class-B tolerance clear borosilicate volumetric flask with a polyethylene (PE) stopper, supplied across 13 capacity/neck-size combinations from 5ml to 2000ml, with tolerances roughly double the equivalent Class-A flask at every capacity.

Class-B Tolerance at the Same Neck Sizes as Class-A
This clear-glass flask uses the same neck-size (N/S) structure as its amber Class-A counterpart, which means accessories and stoppers are interchangeable between the two, but the Class-B tolerance is roughly double the Class-A figure at every matching capacity — for example ±1.2ml at 2000ml here against ±0.6ml on the Class-A equivalent. Class-B suits routine mixing, dilution and teaching-lab use where the tighter Class-A tolerance is not required.

Why are two neck sizes listed for the 50ml and 100ml capacities?
These capacities are offered in two neck-size variants; confirm which N/S size matches your existing stoppers or accessories.
