Qorpak Clear Straight Sided Round Jar GLC-01629 4 oz Lab Bottle

Description

Product Overview

The Qorpak GLC-01629 clear straight sided round jar is engineered for precision laboratory applications where clarity, durability, and reliable sealing are paramount. Constructed from high‑quality borosilicate glass, the jar offers excellent chemical resistance and thermal stability, making it suitable for a wide range of solvents, reagents, and temperature‑sensitive processes. Its 4 oz (approximately 120 ml) capacity provides a balance between sufficient volume for sample handling and a compact footprint that conserves bench space.

The jar features a smooth, straight‑sided design that facilitates easy cleaning, labeling, and stacking. The transparent glass allows users to monitor sample conditions at a glance, reducing the need for opening containers and minimizing exposure to ambient air. The included polypropylene cap, paired with a PTFE (polytetrafluoroethylene) disc, creates a dual‑seal system that effectively prevents moisture ingress and vapor loss, preserving sample integrity over extended storage periods.

Usage

Designed for versatility, this jar excels in a variety of laboratory settings. It is ideal for drying agents, desiccants, and hygroscopic substances that require a hermetic seal to maintain low moisture levels. Researchers in analytical chemistry, organic synthesis, and materials science frequently employ the jar for short‑term sample storage, reagent preparation, and as a vessel for small‑scale reactions that demand clear visual monitoring.

Beyond drying applications, the jar serves well in quality‑control laboratories for holding reference standards, calibration solutions, and test specimens. Its robust cap and PTFE disc ensure that volatile compounds remain contained, while the clear glass body aids in rapid visual verification of sample homogeneity and color changes during experiments.

FAQ

What types of chemicals can be stored in this jar?

The jar is compatible with most non‑aggressive solvents, reagents, and samples. It is not recommended for highly corrosive acids or bases that may attack borosilicate glass.

Can the jar be autoclaved?

Yes, the glass body can withstand standard autoclave cycles. However, the polypropylene cap should be removed before autoclaving to avoid deformation.

Is the PTFE disc replaceable?

The PTFE disc is designed for long‑term use and is not intended to be replaced. If the seal is compromised, the entire cap assembly should be replaced.

How many jars are included in the pack?

The product is sold as a pack of 24 individual jars, each with its own cap and PTFE disc, providing a convenient bulk solution for laboratory inventory needs.

What is the recommended storage temperature range?

The jar performs reliably from -20 °C to 150 °C, covering most laboratory temperature requirements for sample storage and short‑term heating.
