Crafted from high-purity borosilicate 4.2 material, this round glass sheet combines superior thermal resistance with excellent chemical stability, making it an essential component for various laboratory setups. Each unit is manufactured to precise dimensional standards, ensuring compatibility with a wide range of laboratory equipment. With a minimum order quantity of 1 unit, it caters to the diverse needs of research labs, educational institutions, and industrial testing facilities.

Extreme High-Temperature Resistance: The borosilicate 4.2 material enables the glass sheet to withstand temperatures far beyond standard glass, making it suitable for use in high-heat laboratory applications such as heating baths, distillation equipment, and furnace observation ports.
Chemical Corrosion Resistance: The glass exhibits strong resistance to most acids, bases, and organic solvents commonly used in laboratory experiments, ensuring durability and reliability even with prolonged chemical exposure.
Precision Round Design: The round shape and accurate dimensional tolerances allow for easy integration with laboratory equipment such as reaction vessels, beakers, and observation windows, ensuring a secure fit and optimal functionality.
In laboratory heating equipment, such as electric heating mantles or oil baths, the High-Temperature Round Borosilicate 4.2 Glass Sheet serves as a safe and durable observation window. Its high-temperature resistance prevents breakage or deformation when exposed to the heat generated by heating equipment, while its transparency allows researchers to monitor reaction processes in real time without opening the equipment, reducing the risk of contamination and ensuring experiment safety.
For chemical reaction vessels used in organic synthesis or material science research, this round glass sheet provides a reliable sealing and observation component. Its chemical corrosion resistance ensures that the glass remains intact when in contact with reactive chemicals, while the round design enables easy installation on vessel lids or ports, facilitating sample addition and reaction monitoring without compromising the vessel’s integrity.
The glass sheet is engineered to withstand extreme high temperatures, making it suitable for use in laboratory applications where temperatures reach up to several hundred degrees Celsius, far exceeding the capabilities of standard laboratory glass.
The glass sheet features a standard round design and precise dimensions, ensuring compatibility with most common laboratory equipment. For custom or specialized equipment, dimensional adjustments can be discussed to meet specific requirements.
While the glass sheet is manufactured to standard dimensions, it can be professionally cut or modified by qualified glass technicians to fit custom laboratory setups. We recommend consulting with a professional to avoid damaging the glass or compromising its performance.
