ALWSCI 1OZ Glass Vials 30 ml Pack of 100 - Durable Clear Borosilicate

Our review of the ALWSCI 1OZ Glass Vials finds them best suited for labs, makers, and hobbyists who need a reliable, reusable container for small liquid samples and specimens. The single biggest reason to buy is the clear borosilicate glass construction that withstands refrigeration, heating and boiling without clouding, making these vials a practical choice when thermal stability and chemical resistance matter.

Key Features

• Material: Clear borosilicate glass offers thermal resistance and chemical durability for repeated use.
• Capacity: 7.5 dram (1 fl oz) provides a convenient small sample volume for testing, storage, or craft applications.
• Dimensions: Diameter 1.08in and height 3.3in give a narrow, tall profile that fits standard racks and storage tubes.
• Sealing: Each vial ships with a black 24-400 screw cap with PE liner to limit air exposure and reduce deterioration of contents.
• Pack size: The set of 100 vials and 100 caps supplies ample replacement stock for routine lab use or bulk storage projects.

Who It's For

These vials are aimed at laboratory technicians, researchers, and educators who need consistent, thermally stable sample containers for liquids, powders and small specimens. The durable borosilicate construction means they can be cycled through refrigeration or boiling as part of sample preparation.

Hobbyists making small-batch cosmetics or craft oils will also find the quantity and included caps convenient. Those who require pre-sterilized, single-use disposables or specialized closures should look elsewhere, since these vials are supplied loose with standard screw caps and are presented as reusable glassware.
