Description
Product Overview
The Ywhome flat watch glass is engineered to meet the rigorous demands of modern scientific laboratories. Crafted from high‑grade borosilicate glass, the dish offers exceptional chemical resistance, thermal stability, and optical clarity. Its precise 34.5 mm diameter and 1.5 mm thickness create a flat, uniform surface that minimizes distortion and enables accurate visual inspection of samples. The glass is manufactured under strict quality‑control protocols, ensuring each piece meets exact dimensional tolerances and is free from micro‑scratches that could compromise experimental results.
Designed for versatility, this watch glass can be used in a wide range of applications, from simple evaporation tasks to more complex analytical procedures. The thin profile reduces the volume of liquid required for reactions, while the sturdy construction prevents breakage during routine handling. The product dimensions—1.97 × 1.97 × 0.2 inches and a weight of 1.76 ounces—make it easy to store, transport, and integrate into existing lab workflows.

Usage
In laboratory environments, the flat watch glass serves as an essential tool for tasks such as sample drying, crystallization, and microscopic observation. Its flat surface provides a stable platform for placing small quantities of liquids, powders, or solid samples, allowing researchers to monitor reactions without interference from curvature or unevenness. The glass is compatible with standard laboratory equipment, including heating plates, centrifuges, and microscope stages, making it a flexible addition to any bench.
Because the glass is chemically inert, it can safely accommodate a broad spectrum of reagents, from acidic solutions to organic solvents, without leaching contaminants. This property is particularly valuable in analytical chemistry, where purity and reproducibility are paramount. The watch glass also excels in educational settings, offering students a reliable, low‑cost option for hands‑on experiments that demonstrate fundamental principles of evaporation, solubility, and crystallization.

FAQ
Can the flat watch glass be autoclaved for sterilization?
Yes, the Ywhome flat watch glass is made from borosilicate glass that can withstand standard autoclave cycles (121 °C for 15‑30 minutes) without cracking or losing its optical clarity.
Is the glass compatible with organic solvents such as acetone or ethanol?
Absolutely. Borosilicate glass is chemically inert to most organic solvents, including acetone, ethanol, methanol, and chloroform, making it safe for a wide variety of laboratory procedures.
What is the recommended method for cleaning the watch glass after use?
Rinse the glass with distilled water to remove residues, then wash with a mild laboratory detergent. For stubborn deposits, soak in a dilute acid solution (e.g., 10 % nitric acid) followed by thorough rinsing and drying with lint‑free tissue.
How does the flat watch glass differ from traditional curved watch glasses?
The flat design eliminates curvature‑induced optical distortion, providing a true‑to‑scale view of samples. This is especially beneficial for microscopy and precise measurement tasks where flatness is critical.
Can I purchase this product in bulk for large‑scale research projects?
