Watch Glass PATIKIL Multi‑Size Set 50mm 90mm 120mm 150mm Transparent

Description

Product Overview

Patikil’s watch glass collection offers four precisely engineered glass discs with diameters of 50 mm, 90 mm, 120 mm, and 150 mm. Each disc is fabricated from high‑quality table glass that provides excellent chemical durability, ensuring resistance to acids, bases, and solvents commonly used in laboratory environments. The glass thickness of 2 mm delivers a balance between rigidity and flexibility, while the smooth chamfered edges reduce the risk of breakage and make handling safer. The transparent nature of the glass allows clear observation of reactions, and the uniform surface area promotes consistent evaporation rates, which is essential for analytical procedures.

Usage

These watch glasses are suited for a wide range of laboratory and home‑based scientific activities. In research labs, they serve as beaker covers to prevent contamination, as temporary containers for solid or liquid samples, and as evaporation dishes for concentrating solutions. In educational settings, they are perfect for demonstrating crystallization, precipitation, and drying techniques. Hobbyists engaged in small‑scale chemistry, paint mixing, or botanical extractions also benefit from the reliable performance of these glasses. The set’s varied sizes allow users to select the appropriate diameter for the specific vessel or experiment, ensuring optimal fit and efficiency.

FAQ

Can these watch glasses be used for heating?

They are not designed for direct flame or high‑temperature heating. Use a hot plate or oven only if the temperature stays below the glass’s tolerance, typically around 200 °C.

How should I clean the watch glasses after use?

Rinse with distilled water, then wash with a mild detergent. Rinse again thoroughly and allow to air‑dry. Avoid abrasive pads that could scratch the surface.

Are the glasses suitable for storing corrosive chemicals?

Yes, the glass’s chemical durability makes it appropriate for short‑term storage of acids and bases, but always label containers and store them in a safe environment.

What is the recommended way to dispose of broken glass?

Collect fragments in a puncture‑resistant container, label it as broken glass, and follow your institution’s hazardous waste disposal guidelines.

Can I use the watch glasses for evaporation of solvents?

They are ideal for gentle evaporation of low‑boiling solvents. For high‑boiling solvents, consider a dedicated evaporation dish to avoid prolonged exposure.
