Cylinder, Measuring, With Screw Cap

Quick Answer: This graduated Measuring Cylinder is fitted with a threaded screw cap for a leak-proof closure, making it easy to seal, carry and briefly store liquid samples – including volatile ones – without spillage. It uses a different closure method from LabEquip’s ground-glass-stoppered measuring cylinder, which is better suited to careful mixing with a precision glass-on-glass seal.

Product Description

This borosilicate glass measuring cylinder combines a graduated scale for accurate volume measurement with a screw-on cap that threads securely onto the neck. Once capped, the cylinder can be tilted, carried or briefly stored without the risk of the sample leaking out, which is particularly useful when handling volatile liquids that would otherwise evaporate or spill from an open or loosely capped container.

What Makes This Instrument Distinct

LabEquip offers measuring cylinders with different closure types to suit different working needs. This screw-cap version threads on and off quickly and gives a reliably leak-proof seal for carrying or briefly storing a capped sample, which makes it convenient for routine repeated use. Our ground-glass-stoppered measuring cylinder instead uses a precision-ground glass joint, which is generally preferred where a very tight, chemical-resistant seal for mixing is the priority. Choosing between them depends on whether quick, repeated leak-proof access (this screw-cap version) or a precision ground-glass mixing seal matters more for your application.

Specifications

Care & Maintenance

• Rinse thoroughly after use and dry before storage to prevent residue building up on the graduated scale or in the cap threads.
• Check the cap seats fully and evenly before carrying a capped sample, to confirm the leak-proof seal is properly engaged.
• Avoid overtightening the cap, which can strain the threads over repeated use; hand-tight is normally sufficient for a secure seal.
• Store upright and protected from impact, since borosilicate glass resists heat and chemicals well but can still chip or crack from a hard knock.

Frequently Asked Questions

What is the screw cap for?
It threads securely onto the cylinder’s neck to create a leak-proof closure, making the cylinder safe to tilt, carry or briefly store once capped, including for volatile liquids.

How is this different from the ground-glass-stoppered measuring cylinder?
The screw cap threads on and off quickly and gives a reliable leak-proof seal for carrying, while the ground-glass stopper gives a tighter, more chemical-resistant glass-on-glass seal generally preferred for mixing.

What is this cylinder made from?
It is made from borosilicate glass, which offers good heat and chemical resistance for laboratory use.

What capacity and graduation interval does this cylinder have?
Exact capacity and graduation intervals vary by size; please confirm your requirement with our sales team.

Is this cylinder suitable for volatile liquids?
Yes, the leak-proof screw cap helps contain volatile samples once capped; confirm your specific liquid and application with our sales team.

How should I care for the screw cap and threads?
Keep the threads clean and dry, avoid overtightening, and check the cap seats fully before carrying a capped sample.
