Test Tube, 12x100 mm, Borosilicate Glass, Pack of 100

Test Tubes 12x100 mm Borosilicate Glass

These test tubes are made from borosilicate 3.3 glass, known for its outstanding thermal resistance, optical clarity, and chemical durability—making them ideal for laboratory, research, and teaching use. Each tube has an outer diameter of 12 mm and a length of 100 mm, with a capacity typically ranging from 7 to 12 mL depending on wall thickness and design. Tubes feature either rimless or reinforced beaded rims for safe, smooth sample transfer and compatibility with rubber stoppers.

With uniform, thin walls (generally about 1 mm thick), these test tubes are well suited to repeated heating, autoclaving, and a broad variety of sample handling procedures. Supplied in packs of 100, they are commonly used for multi-sample processing, chemical reactions, culture work, and specimen storage in labs and industrial settings.
