1) The speicifaction of  Quartz graduated cylinderis : 10ml--500mm

2). The appearanceof  Quartz graduated cylinder looks beautiful and easy for people to carry with.

3). The quality of Quartz graduated cylinder is also guaranteed.

Main technicaldata:
1Physical, chemical properties target:
1Chemical composition: The aluminum, hard, the calcium, the magnesium, the titanium, copper, the nickel, the cobalt, the manganese, the lithium, the boron, the potassium, the sodium 13 impurity element's total content is not bigger than 0.003%. And: Boron ≤0.1* 10%; Copper ≤0.1* 10%; Iron ≤0.1* 10%.

2Thermostability: The test specimen under 1100 the temperature emergency, experiments three times, does not produce the crack and comes down.

3Anti-crystallinity: The test specimen under 1200 the temperature constant temperature a half hour, does not allow to present the diameter to be bigger than 0.5 millimeter crystallization lemon spot.

 2Divides into three levels according to the outward appearance target. Specification size: (unit: Millimeter)
1The gas builds up the vitreous silica glass tube's specification size to conform to the next table stipulation. 35 40 45 50 55 ±1.0 1.8-2.5 ±0.3
60 65 70 75 ±1.0 1.8-2.5 ±0.3
80 85 90 95 ±1.0 1.8-2.5 ±0.3
100 110 120 130 140 ±1.0 2-3.5 ±0.4

Explanation: Gao Chunqi builds up the vitreous silica glass tube mainly to use in the vitreous silica glassware which, household utensils' manufacture the semiconductor industry and the electron tube industry, the electro-optic light industry use, with other related scientific research, production need.
