About Okulab Glass Test Tubes,16ml Test Tube With Round
In the test tube kit, the test tubes are made of 3.3 borosilicate and the stoppers are made of cork. These test tubes have good chemical stability, light weight, durability and robustness. They can meet basic experimental needs and are suitable for storing items that need to be kept dry or some liquids, and are widely used in a variety of applications. Tips: No more than 1/2 of the capacity of the test tube when used to contain the solution and no more than 1/3 of the tube when heated. The outside of the test tube should be wiped dry before heating, and should be clamped by test tube clamp when heating. When heating liquid, the mouth of the tube should not be pointed at people, and the test tube should be tilted to 45 degrees from the desktop, while constantly oscillating, and the upper end of the flame should not exceed the surface of the liquid in the tube. When heating solids, the mouth of the tube is slightly tilted downward.
