High-quality reusable test tube made from ASTM E-438 Type I Class A borosilicate 3.3 glass, compliant with EN ISO 4142.
Straight rim ensures uniform wall thickness and mechanical strength.
Ideal for general lab use, heating, or sample storage.
Chemically inert, autoclavable, and reusable.
What is the VT.DB31 tube used for?
It is designed for routine laboratory work, including sample preparation, heating, mixing, and the analysis of liquid or solid materials. The AllChimie test tube category presents this family as suitable for those standard applications.
Is the VT.DB31 reusable?
Yes. The category page clearly identifies VT.DB31 as a reusable test tube, unlike the disposable references in the same family.
What type of rim does this tube have?
VT.DB31 is specified as a straight rim test tube, which corresponds to a standard open tube format without screw finish.
What glass quality is used?
The product is described as made from borosilicate glass 3.3, with ASTM E-438 Type I Class A glass quality, which is suitable for repeated laboratory use.
Which standard does this tube comply with?
VT.DB31 is stated as compliant with EN ISO 4142.
What laboratory environments is this tube suitable for?
AllChimie describes test tubes as suitable for research, quality control, chemistry, cosmetics, and food laboratories, with standard geometry compatible with racks, heating systems, and routine handling.
Why is borosilicate 3.3 useful for a reusable test tube?
Because AllChimie describes borosilicate 3.3 test tubes as offering good thermal resistance, high chemical inertness, and dimensional stability, which are important advantages for repeated use.
How does VT.DB31 fit into the AllChimie test tube range?
Within the AllChimie test tube family, VT.DB31 is the reusable borosilicate 3.3 model, while VT.VR51 is presented as a disposable screw-cap culture tube and VT.DU71 as a disposable straight-rim tube.
