Watch Glass Beaker Cover Set 10PCS 100mm VOVCIG High Temp Lab Lids

Description

Product Overview

The VOVCIG Watch Glass Beaker Cover Set is engineered to meet the rigorous demands of modern scientific laboratories. Each set contains ten identical 100 mm glass lids that are crafted from high‑quality borosilicate glass, offering superior resistance to thermal shock and chemical corrosion. The transparent nature of the glass allows researchers to monitor reactions without removing the cover, preserving the integrity of the experiment while reducing the risk of contamination. Dimensions of each lid are precisely calibrated to fit standard beakers and evaporating dishes, ensuring a snug seal that prevents dust, debris, and airborne particles from entering the vessel. The set is packaged in a compact box measuring 4.37 x 4.33 x 2.01 inches, weighing just over one pound, making it easy to store and transport within laboratory environments.

Usage

These watch glass covers are versatile tools suitable for a wide range of laboratory procedures. In chemistry labs, they are commonly used to cover beakers during heating, stirring, or evaporation processes, providing a barrier against splashes and condensation while allowing visual access to the contents. In biology and environmental science settings, the lids protect culture plates and petri dishes from airborne contaminants, supporting sterile conditions essential for accurate results. The high temperature resistance enables safe use in ovens, hot plates, and autoclaves up to 300°C, making them ideal for protocols that require prolonged heating or rapid temperature changes. Additionally, the lids can be repurposed as protective covers for small containers such as test tubes, flasks, or reagent bottles, extending their utility beyond the primary application.

FAQ

Can these lids be used on containers larger than 100 mm?

While the lids are optimized for 100 mm openings, they can safely cover slightly larger vessels as long as the fit remains snug enough to prevent gaps. For significantly larger containers, we recommend selecting a size that matches the opening to maintain optimal protection.

Are the glass lids safe for use in an autoclave?

Yes, the borosilicate glass composition is designed to withstand autoclave temperatures up to 300 °C, making them suitable for sterilization cycles without cracking or deforming.

What should I do if a lid arrives broken?

Contact VOVCIG customer service within 24 hours of receipt, providing the order number and a photo of the damage. The support team will arrange a replacement shipment at no additional cost.

Do the lids interfere with heating efficiency?

No, the thin glass design allows heat to transfer efficiently while still providing a protective barrier. Experiments that require rapid heating will not be adversely affected.

Can the lids be reused after cleaning?

Absolutely. The glass can be cleaned with standard laboratory detergents and rinsed thoroughly. Because the material is chemically inert, it will retain its clarity and performance after multiple cleaning cycles.
