PATIKIL 80 mm Diameter Watch Glass Transparent Lab Beaker Cover 6 Pack

Description

Product Overview

The PATIKIL 80 mm transparent watch glass is engineered for precision and durability in both professional laboratory environments and home science projects. Constructed from high‑quality table glass with a thickness of 2 mm, each disc offers a smooth, chamfered edge that reduces the risk of breakage while providing a reliable seal for beakers, flasks, and other containers. The glass is chemically inert, ensuring that it will not react with acids, bases, or solvents, which preserves sample purity and prevents contamination. With a weight of 109 g per disc, the watch glasses are easy to handle yet sturdy enough to support routine handling, weighing of corrosive substances, and temporary storage of liquids or solids. The six‑pack packaging delivers consistent performance across multiple experiments, reducing the need for frequent re‑ordering and supporting efficient workflow in busy labs.

Key specifications include an 80 mm (3.15″) diameter, 2 mm thickness, and a transparent finish that allows clear visual monitoring of reactions. The product dimensions of the package are 5.98 x 3.98 x 1.54 inches, weighing 6.38 ounces, making it compact and easy to store on laboratory shelves or in safety cabinets. The watch glass is ranked #60 in the Lab Watch Glasses category on Amazon, reflecting its popularity among researchers who value its balance of cost‑effectiveness and performance.

Usage

Designed for versatility, the PATIKIL watch glass serves a wide range of applications. In a typical laboratory setting, it can be used as a beaker cover to minimize evaporation, protect samples from airborne contaminants, and prevent splashes during stirring or heating (provided the heating method does not involve direct flame). The smooth, chamfered edge makes it ideal for weighing corrosive substances, as the glass can be placed on a balance without scratching the surface. Researchers also employ these watch glasses for suspension drop culture tests, temporary storage of solid samples, and as a convenient platform for mixing small volumes of reagents.

Beyond the laboratory, the transparent watch glass is useful in educational settings, hobbyist chemistry kits, and even in home kitchens for tasks such as covering bowls during fermentation or protecting food items while microwaving (again, avoiding direct flame). The clear material allows users to monitor the progress of reactions, crystallization, or drying processes without removing the cover, thereby maintaining a controlled environment.

Before each use, it is recommended to wash the glass with mild detergent and dry it thoroughly to eliminate any residues that could interfere with experimental results. After use, the glass should be cleaned promptly, avoiding abrasive scrubbers that could damage the chamfered edge. Proper cleaning extends the lifespan of each disc and ensures consistent performance across the entire six‑pack.

FAQ

Can the watch glass be used for heating?

The watch glass is not designed for direct flame heating. It can tolerate moderate temperature increases when placed in a water bath or incubator, but direct exposure to open flame may cause rupture.

Is the glass compatible with all chemicals?

Yes, the glass is chemically inert and compatible with most laboratory reagents, including strong acids, bases, and organic solvents. However, extremely aggressive mixtures should be tested for compatibility before prolonged exposure.

How should I clean the watch glass after use?

Rinse the glass with distilled water, wash with a mild detergent, and dry with a lint‑free cloth. Avoid abrasive pads that could damage the chamfered edge.

What size beakers does the 80 mm watch glass fit?

The 80 mm diameter is ideal for standard 250 ml to 500 ml beakers and flasks that have a matching opening. It also works well with smaller containers that have a similar rim size.
