Made of borosilicate glass, the maximum operating temperature can be withstood is 500℃. When the temperature is above 525℃, the glass begins to soften and begin to change from solid state to fluid state. Borosilicate glass 3.3 mean the linear thermal expansion coefficient is 3.3. It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability.
It is recommended that the operating conditions should be within - 70℃. At extreme low temperature, the temperature difference should not exceed 100K. It is also suitable for use in liquid air (about - 192 ℃). When the refrigerant is put into the test tube, the maximum capacity is limited to 3/4, and it is inclined to 45 degree.
Aluminium screw cap with silicon rubber liners or w/o liners. Autoclavable.
