Test Tube Labels Test tube labels are small adhesive labels that are used to identify the contents of test tubes. They are typically made of a durable, waterproof material and are designed to withstand the conditions of a laboratory environment. Test tube labels can be used to identify a variety of different types of samples, including biological, chemical, and environmental samples. Our test tube labels track samples in the fields of chemistry, hematology, virology, genetics, DNA sequencing, forensics and drug discovery for a variety of purposes ranging from diagnostic testing to disease prevention testing.
