Test Tube, 12x75 mm, Neutral Hard Glass, Pack Of 100

A neutral hard glass test tube, size 12x75 mm, is a versatile laboratory glassware item used for mixing, heating, and storing liquids or samples. It is cylindrical with an open top and rounded bottom, made of neutral (soda-lime) hard glass that does not interfere with chemical reactions and provides excellent resistance to thermal and chemical stress. These test tubes typically have a wall thickness of about 1 mm, ensuring durability and the ability to withstand repeated heating and cooling cycles. They are commonly sold in packs of 100 and are widely used in research, industrial, educational, and pharmaceutical laboratories for various experimental and testing purposes. The transparency and chemical inertness of neutral glass make these tubes suitable for precise scientific measurements and observations.
