Product description

The material is high borosilicate 3.3. And the working temperature is 450-500C.Borosilicate 3.3 series glass

is a kind of special type glass material with the features of low expansion coefficient,high temperature resistance,
high intensity, high rigidity, transparency 
and chemical stability. It doesn't explode in high temperature, and can 

be forged and drawn to variety of formation when soften.

The features as below :

 

1.)Test tube with round bottom and flat bottom.

2.)Rim: with rim or without rim

3.)Material: borosilicate 3.3 or borosilicate 4.0

 

Products description :

1.) Premium quality glass tubes are produced from borosilicate glass that provides excellent chemical   resistance and durability. Clear Borosilicate glass test tubes can be used for chemical experiments as well as experiments related to density and other physical properties of liquids.

2.) Tubes feature well-rounded bottoms and smooth fire-polished rims.

3.) Our Glass Test Tubes are cost-effective solution for diverse chemical applications.

4.)Production according to ISO standards or as per your specifications.

5.) Standard packaging is shrink wrapped firstly, then put into strong corrugated carton.
