Lab Glassware Manufacturer manufactures and exports the Volumetric Flask With Polyethylene Stopper, Unserialized, Class A from its production facility in Ambala, Haryana, for Class-A volumetric measurement in laboratories in India and to export buyers that have recently included Mozambique, Malawi and Zambia — part of a wider base of enquiries from across Southern Africa.
Quick answer: This is a Class-A tolerance borosilicate volumetric flask with a polyethylene stopper, supplied across the same extended capacity range as the penny head glass stopper version — 1ml up to 6000ml — each capacity matched to a specific tolerance and stopper size.

Polyethylene Versus Glass Stopper on the Same Flask Range
This flask shares its capacity, tolerance and stopper-size structure with the penny head glass stopper version of the same range, differing only in the stopper material: polyethylene is lighter, will not chip like a ground-glass stopper, and is often preferred for routine daily use, while a glass stopper can offer better resistance to certain solvents that may swell or degrade plastic over time. Choose based on which trade-off matters more for the specific reagents in use.
Frequently Asked Questions
How does this differ from the glass stopper version?
It shares the same capacity and tolerance structure but uses a polyethylene stopper instead of a glass penny head stopper.
What is the largest capacity available?
The range extends up to 6000ml, alongside a 4000ml size.
When should I choose glass over polyethylene stoppers?
Glass stoppers can offer better resistance to solvents that may swell or degrade plastic; polyethylene is lighter and resists chipping.
