PRODUCT INFORMATION
About this product
This pack contains two 18 × 150 mm rimmed, round-bottom test tubes made from borosilicate glass. The medium-size laboratory tubes provide a clear vessel for holding, mixing, observing and suitably heating small samples.
Buyers may search for these as 18 × 150 mm test tubes, borosilicate chemistry tubes, heat-resistant glass test tubes or a laboratory test-tube pack of two. The smaller pack suits individual requirements, replacement stock and limited practical work.
Inspect both tubes for chips, cracks or scratches before use. Apply temperature changes gradually, use a compatible test-tube holder and never point a tube being heated toward any person.
