Product overview
What This Product Is And Who It Is For
Blood collection tubes used to collect, preserve and transport blood samples, made from glass or plastic with pre-added additives that keep blood components stable. Colour coding identifies the additive and the intended test: purple tubes with EDTA anticoagulant for complete blood count and blood typing, green tubes with heparin for biochemical and immunological tests, blue tubes with sodium citrate for coagulation function tests, grey tubes with sodium fluoride and potassium oxalate for blood glucose and lactate, and red tubes without additive for serum work.
Problems It Solves
- Wrong additive for a test invalidates the result, which colour coding prevents at the draw
- Manually added anticoagulant is imprecise, so tubes are pre-dosed
- Serum contaminated by cells distorts biochemistry, which separation gel tubes address
- Mixed suppliers give inconsistent additive quality across a laboratory
- Glass breakage in transport is a risk in some workflows, so plastic tubes are available
Who It Is For
- Hospital and laboratory procurement departments
- Diagnostic laboratory chains
- Medical consumable importers and distributors
- Community health and screening buyers
- Private clinic groups
Key benefits
Why Buyers Choose It
- Colour coding prevents the wrong additive reaching the wrong test, which is a common pre-analytical error
- A full colour range from one supplier keeps additive quality consistent across a laboratory
- Glass and plastic options let a laboratory match cost and breakage risk to its workflow
- Separation gel tubes shorten processing by holding the clot away from the serum after centrifugation
- Pre-added additives remove manual dosing at the point of draw

Quality and compliance
Quality Control And Certification
Quality Control
- Draw volume is verified against the tube specification
- Additive dosing is checked per batch
- Cap seal and vacuum retention are tested
- Colour coding is verified against the additive at packing
- Batch and expiry data are printed on each carton
Customisation and comparison
Options And Alternatives
Customisation Options
- Tube size, material and additive mix per carton
- Label artwork and barcode format
- Rack and carton packing configuration
- Label language
- Export carton marks and palletising
Compared With Other Options
- Syringe and manual transfer
- Vacuum tubes with pre-dosed additive remove the manual transfer and dosing steps
- Glass versus plastic tubes
- Plastic reduces breakage risk in transport, while glass suits workflows that require it
- Plain tubes without separation gel
- Gel tubes hold the clot away from the serum after centrifugation, which shortens processing
Use guide
How To Use It Correctly
Step
Select the tube colour that matches the requested test
Step
Draw to the indicated fill line so the additive to blood ratio is correct
Step
Invert the tube gently the number of times stated for that additive
Step
Label the tube at the patient side before transport
Step
Store and transport according to the additive requirement and the laboratory protocol
