Description

Product Overview

The JG Finneran 91802 wide mouth jar is engineered from high‑quality clear borosilicate glass, a material renowned for its thermal stability, chemical resistance, and optical clarity. Each jar holds precisely 60 mL, making it an optimal size for a variety of laboratory applications, from drying reagents to storing small samples. The jar features a straight‑sided, short, wide‑mouth design that facilitates rapid filling, easy inspection of contents, and straightforward cleaning. The accompanying closure is a white polypropylene cap with a PTFE‑lined seal, delivering a reliable, leak‑free barrier that resists aggressive solvents and prevents moisture ingress.

Usage

Designed for the demanding environment of research laboratories, this jar excels in tasks such as drying organic solvents, preserving hygroscopic powders, and holding reference standards. Its wide mouth allows quick access for adding or removing materials, while the PTFE‑lined cap ensures that volatile compounds remain contained during storage. The jar’s robust glass construction tolerates repeated heating and cooling cycles, making it suitable for use in ovens, desiccators, and refrigerated storage. Whether you are a chemist, biologist, or quality‑control technician, the 60 mL capacity fits comfortably on standard lab benches and can be stacked efficiently to maximize space.

FAQ

What temperature range can the jar withstand?

The borosilicate glass is rated for continuous use from -40 °C up to 350 °C, making it suitable for most laboratory heating and cooling applications.

Is the PTFE lining compatible with aggressive solvents?

Yes, the PTFE lining provides excellent resistance to most organic solvents, acids, and bases, ensuring the cap remains intact and leak‑free.

Can the jars be autoclaved?

While the glass itself can tolerate autoclave conditions, the polypropylene cap should be removed before autoclaving to avoid deformation.

How many jars are included in the pack?

The product is supplied as a pack of 24 individual jars, each with its own PTFE‑lined closure.

What is the best way to clean the jars after use?

Rinse the jar with distilled water, then use a mild laboratory detergent if needed. The smooth interior surface of borosilicate glass allows for easy removal of residues, and the PTFE‑lined cap can be cleaned separately with compatible solvents.
