Glass Test Tubes
Glass tubes are made of borosilicate glass that withstands thermal shock and chemical attack, reduces pH
changes and contaminants leached from soda lime glass tubes. The tubes are uniform bottoms, fire-polished
rims, consistent lengths, and convenient packaged in shrink-wrapped shelf inner box. They can be used for
mixing heating and/or holding small quantities of chemicals for assays, as well as tissue culture, blood banks,
and other laboratory experiments.

Disposable Glass Test Tubes
Made of borosilicate glass, suitable for general mixing, simple laboratory work, as well for use with samples
hich are susceptible to pH change, will withstand moderate warming (e.g. in a water bath) Meets ASTM E 890
Specification, Standard specification for Disposable Glass Culture Tubes
