Types of test tubes
What are the different types of test tubes?
There are several types of test tube materials: glass, plastic, metal, and ceramic. Glass and plastic are the most common, some are designed to be reused, while others are disposable.
How many types of laboratory tube are there?
Blood Collection Tubes
| Tube cap color | Additive |
|---|---|
| Red or gold (mottled or “tiger” top used with some tubes) | Serum tube with or without clot activator or gel |
| Green | Sodium or lithium heparin with or without gel |
| Lavender or pink | Potassium EDTA |
| Gray | Sodium fluoride, and sodium or potassium oxalate |
What is standard test tube?
A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom. Test tube. Two small test tubes held in spring clamps.
What are the three uses of test tube?
What is the use of a test tube? Test tubes are very important laboratory tools in the biological, chemical, and medical sciences. In general, they are used to mix chemicals, hold liquids, heat liquids, grow bacteria, and collect or store bodily fluids, like blood and semen.
What is EDTA tube used for?
EDTA acts as an anticoagulant, binding the calcium ions and interrupting the clotting of the blood sample. EDTA is used for most hematology procedures, assessing complete blood count, preparing EDTA plasma, whole blood collection and bone marrow specimens.
What color is a EDTA tube?
Lavender
EDTA whole blood = Lavender (purple) top tube Label this tube with owner name, animal ID, and as EDTA whole blood.
What are lab test tubes called?
They are open at the top and rounded at the bottom, and usually made of glass or plastic materials. Some are designed to be reused, while others are disposable. A type of labware, test tubes are sometimes called culture or sample tubes, depending upon the application.
What is test tube and its function?
Test tubes are widely used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents.
What is test tube method?
Widal test (tube method) helps to detect typhoid fever and paratyphoid fever which are collectively known as enteric fever. Enteric fever is caused by the ingestion of food or water which is contaminated by bacteria. This test is performed through the tube method.
What are lab tubes called?
Culture tubes, sample tubes or test tubes are an important part of laboratory glassware or plasticware which is open at the top and closed at the bottom. Glass is the preferred choice of material for test tubes used in scientific laboratories because they’re well resistant to heat.
What are lab test tubes called?

The following tests may be drawn in the same Lavender (Purple) top tube: CBC, SED Rate (ESR), Reticulocyte. Draw an extra lavender for each Glycohemoglobin and BNP. EDTA Sodium fluoride (serum tube) For glucose determinations.
What are centrifuge tubes called?
Centrifuge tubes, also called centrifuge tips, are placed within the centrifuge and spun at very high velocity for a set amount of time.
What are test tubes in microbiology?
Test tubes are widely used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents.
