PATIKIL 60mm/70mm/90mm/100mm Diameter Watch Glass, 1 Set Beaker Cover Smooth Edges Chamfered Arc for Laboratory, Transparent

Description

Product Overview

The PATIKIL watch glass collection is engineered for precision and durability, offering four standard diameters—60 mm, 70 mm, 90 mm, and 100 mm—to accommodate a wide range of laboratory vessels. Each glass is fabricated from high‑quality table glass with exceptional chemical resistance, ensuring that corrosive reagents, acids, and solvents do not degrade the surface. The smooth, chamfered edges reduce the risk of accidental cuts while providing a comfortable grip for easy handling. Transparent construction allows clear visual monitoring of reactions, crystallization, and evaporation processes without the need to remove the cover.

Dimensions are carefully calibrated: the 60 mm glass fits standard 100 ml beakers, the 70 mm glass pairs with 250 ml containers, the 90 mm glass is ideal for 500 ml flasks, and the 100 mm glass comfortably covers 1 L beakers. Each piece weighs less than 2 grams, making them lightweight yet robust enough to withstand routine laboratory handling. The set is packaged in a compact, recyclable box measuring 6.06 × 5.87 × 2.01 inches, facilitating storage and transport while protecting the glass from breakage.

Usage

These watch glasses are versatile tools for both academic and industrial environments. In chemistry labs, they serve as beaker covers to minimize evaporation, prevent contamination from airborne particles, and reduce the risk of splashes during heating (provided the glass is not directly exposed to open flame). In biological research, the transparent surface enables easy observation of cell cultures, agar plates, and micro‑titer plate preparations. Hobbyists and home experimenters benefit from the same protective qualities, using the glasses for small‑scale synthesis, paint mixing, or even culinary applications such as covering sauces while simmering.

Before each use, it is recommended to rinse the glass with distilled water and allow it to air dry, eliminating residues that could interfere with experimental outcomes. After use, the glass should be cleaned with a mild detergent, rinsed thoroughly, and dried before storage. The set is not intended for direct flame heating; instead, it can be placed over a beaker that is heated indirectly, ensuring safety and preserving the integrity of the glass.

FAQ

Can I use the watch glass directly over an open flame?

No. The watch glass is not designed for direct flame exposure. Use it as a cover over a beaker that is heated indirectly to avoid thermal shock and potential rupture.

How should I clean the watch glasses after use?

Rinse the glass with distilled water, wash with a mild laboratory detergent, rinse thoroughly, and allow it to air dry. Avoid abrasive cleaners that could scratch the surface.

Are the glasses compatible with all types of laboratory chemicals?

Yes. The glass is made from high‑quality table glass with excellent chemical resistance, making it suitable for most acids, bases, solvents, and organic reagents commonly used in labs.
