Plastic Test Tubes Frozen Test Tube Vial Container Storage Screw Cap for Lab Laboratory Science
Application
The plastic test tube is mainly used in laboratories to store samples at low temperatures, to prevent sample volatilization. Plastic test tubes with caps can be used to store powders, liquids, and semi-liquids such as aqueous samples and other reagents.
Advantage
Screw-in and cover pad design seals well and prevents liquid spillage. Test lab tubes are transparent and you can see the remaining amount. Storage tubes, made of durable plastic, are easier to store than glass. Plastic tubes with caps is reusable, low-temperature resistant, and can be frozen for a long time.

They are a good size almost 4 inches tall. I don't need a rack to keep them upright. The screw top is easy to use and stays tight.
