Clear Tall Jar Thomas Scientific GLC01656 8 oz PP Cap PTFE Disc

Description

Product Overview

The Thomas Scientific Clear Tall Jar, model GLC01656, is a precision‑engineered glass container that meets the rigorous demands of modern laboratory environments. Constructed from high‑quality clear glass, the jar offers excellent chemical resistance, allowing it to safely hold a wide range of solvents, reagents, and samples without risk of degradation or leaching. The jar holds 8 fluid ounces (approximately 237 milliliters) of material, making it an ideal size for routine drying, storage, and small‑scale reactions. Its straight‑sided, tall profile maximizes internal volume while maintaining a compact footprint that fits easily into standard lab racks, shelves, and drying ovens.

One of the standout features of this jar is the secure closure system. The included polypropylene (PP) cap is engineered for durability and resistance to most chemicals, while the integrated PTFE (polytetrafluoroethylene) disc provides an additional barrier against moisture ingress and vapor loss. This dual‑seal design ensures a tight, leak‑proof seal that preserves sample integrity over extended periods. The cap threads are precisely machined to match the jar mouth, delivering a consistent torque and preventing over‑tightening that could damage the glass. The PTFE disc, known for its low friction and high temperature tolerance, further enhances the seal performance, especially in applications requiring repeated opening and closing.

Dimensions of the jar are carefully calibrated: the overall height measures 5.39 inches (13.7 cm) with a diameter of 2.24 inches (5.7 cm), resulting in a stable base that resists tipping during handling. The jar weighs 12.19 pounds when filled, providing a solid feel that reduces the likelihood of accidental spills. The product is certified by Thomas Scientific, a trusted name in laboratory supplies, and carries the ASIN B00UCRMG4O for easy reference in online catalogs. Its best‑seller rank of #24 in Lab Drying Jars underscores its popularity among professionals who value reliability and performance.

Usage

This clear tall jar is versatile across a broad spectrum of laboratory tasks. In analytical chemistry, it serves as an ideal vessel for drying solvents, reagents, and solid samples prior to weighing or further processing. The transparent glass allows technicians to visually monitor the drying progress, ensuring that moisture levels are reduced to the desired threshold before proceeding. In microbiology, the jar can be used to store culture media or dried bacterial pellets, with the PP cap and PTFE disc preventing contamination from ambient humidity.

Because the jar is compatible with standard laboratory equipment, it can be placed directly into drying ovens, desiccators, or vacuum chambers without the need for adapters. The robust PP cap tolerates temperatures up to 120 °C, while the PTFE disc remains stable at even higher temperatures, making the jar suitable for heat‑sensitive protocols that require repeated heating cycles. Researchers working in pharmaceutical development often employ this jar to dry active pharmaceutical ingredients (APIs) before granulation, ensuring consistent particle size and purity.

Field work and on‑site testing also benefit from the jar’s secure sealing system. Environmental scientists collecting soil or water samples can transport the jar in rugged conditions, confident that the PTFE disc will maintain sample integrity despite fluctuations in temperature and humidity. The clear glass construction also facilitates quick visual checks without opening the container, saving valuable time during field campaigns.

Overall, the jar’s design addresses the practical needs of chemists, biologists, material scientists, and quality control personnel who require a dependable, easy‑to‑use container for drying, storage, and transport of laboratory materials.

FAQ

Can the jar be used with aggressive solvents such as acids or bases?

Yes, the clear glass body is chemically inert to most acids, bases, and organic solvents. The polypropylene cap is resistant to many chemicals, but for highly aggressive reagents, verify compatibility with the specific solvent.

Is the PTFE disc replaceable if it becomes worn?

The PTFE disc is designed for long‑term use and is not intended to be removed. If the seal performance degrades, we recommend replacing the entire cap assembly to maintain optimal sealing.

What temperature range can the cap and disc withstand?

The polypropylene cap is rated up to 120 °C, while the PTFE disc can tolerate temperatures up to 260 °C, making the jar suitable for most laboratory drying and heating applications.

How do I clean the jar after use?

Rinse the jar with deionized water, followed by a mild detergent if needed. Rinse thoroughly and allow to air dry. The cap and PTFE disc can be cleaned with the same procedure, avoiding abrasive scrubbers that could damage the PTFE surface.

Is the jar compatible with standard laboratory racks?

Yes, the jar’s dimensions are designed to fit common rack sizes and shelf configurations, allowing easy organization alongside other standard lab glassware.
