Laboratory Test Tubes

Key Features and Benefits

• Heat Resistant Material: Constructed from borosilicate glass, which has a very low coefficient of thermal expansion, allowing it to withstand high temperatures and rapid temperature changes (thermal shock) without breaking.
• Round Bottom Design: The round bottom allows for uniform heating over a Bunsen burner flame or in a heating block and facilitates easy mixing of contents.
• Chemical Resistance: Borosilicate glass is highly resistant to a wide range of chemicals, preventing unwanted reactions between the tube material and the chemicals being used.
• Transparency and Observation: The high clarity of the glass allows for clear observation of reactions, color changes, and sample analysis.
• Reusability and Easy Cleaning: These tubes can be sterilized by boiling or autoclaving and are easy to clean by hand or in a dishwasher due to the non-porous glass surface.
• Plain/Rimless Design: The specific “1236” code likely refers to a model without a rim, designed for easy liquid pouring and reducing the risk of contaminants leaching from the glass.
