Questron Teflon - Model CT-562-101 -25mL Vial

Low expansion Borosilicate 3.3 Laboratory Glassware as per ASTM E-438 Type –I. We use Borosilicate 3.3 is highly resistant to almost all Chemicals, salt solutions and other organic solvents. The labware are highly heat resistant, high resistance to thermal shock & high mechanical strength. Thermal expansion between 0-300/°C is 33 x 10-7/°C and thermal conductivity 0.0027 cal/cm³/°C/Sec. Borosilicate 3.3 can handle temperature up to 240 degree Celsius for continuous usage under general laboratory conditions , whereas it can withstanding temperature around 400-450 degree Celsius for short term usage.
