Wheaton 216639 Clear Glass Round 16oz Safety Coated Jar, without 70-400 Screw Cap (Pack of 12)

Description

Product Overview

The Wheaton 216639 clear glass round jar is engineered for laboratory environments where reliability, safety, and precision are paramount. Constructed from high‑quality soda‑lime glass that meets USP Type III standards, each 16 oz (473 ml) jar provides a clear view of its contents, enabling easy visual inspection without compromising chemical integrity. The exterior is treated with a PVC‑based plastisol safety coating that adheres firmly to the glass surface. This coating serves a dual purpose: it retains any liquid or powder that might escape if the jar were to fracture, and it creates a textured, non‑slip surface that enhances handling confidence, even when the jar is wet or covered in residue. The jar dimensions—approximately 2.5 inches in diameter and 4 inches tall—fit comfortably within standard laboratory storage racks and autoclave trays, though autoclaving is not recommended due to the coating composition. The product ships in a sturdy cardboard case containing twelve individual jars, each protected by a thin internal sleeve to prevent chipping during transport.

Usage

Designed for a broad range of scientific and industrial applications, these jars excel in drying, storage, and sample preparation tasks. In a chemistry lab, technicians often use the clear glass to monitor solvent evaporation rates, while the safety coating ensures that any accidental breakage does not result in hazardous spills. The non‑slip exterior is especially valuable in wet environments such as microbiology workstations, where jars may be rinsed repeatedly or filled with aqueous solutions. The 16 oz capacity strikes a balance between sufficient volume for bulk reagents and manageable size for precise weighing. Users in quality‑control facilities appreciate the jars for holding reference standards, where the clear glass allows for quick verification of label integrity without opening the container. Additionally, the jars are suitable for educational settings, providing students with a safe, reusable vessel for experiments involving solids, liquids, or mixed phases.

FAQ

Can the safety coating be removed for cleaning?

The safety coating is permanently bonded to the glass surface and is not intended to be removed. Cleaning should be performed with mild detergents and a soft cloth; abrasive cleaners may damage the coating.

Is the jar compatible with all types of chemicals?

The clear soda‑lime glass is suitable for most aqueous solutions, solvents, and solid reagents. However, highly corrosive acids such as hydrofluoric acid should be avoided, as they can etch the glass.

Can the jar be autoclaved for sterilization?

Autoclaving is not recommended because the high temperature and steam can degrade the plastisol safety coating, reducing its effectiveness.

What is the recommended method for sealing the jar?

While this listing does not include screw caps, Wheaton offers compatible caps that thread onto the jar mouth, providing a secure seal for long‑term storage.

How does the non‑slip coating improve safety?

The textured coating increases friction between the jar and the user’s hand, reducing the likelihood of accidental drops, especially when the jar is wet or covered in residue.
