Specimen Collection Tubes 5ml Lab Vacuum EDTA K2
Product type: 5 mL EDTA K2 tubes with purple cap, 100 pieces per wrap package. Interior coating of EDTA K2 supports hematology workflows by ensuring consistent anticoagulation during sample handling. Best for veterinary clinics and small- to mid-sized labs that need rapid, reliable blood draws in routine diagnostics. A potential limitation is that non-vacuum tubes may require a separate draw method in some settings. Suitable for clinics prioritizing ready-to-use packs and straightforward inventory.
Blood Collection Tubes 5mL – K2 EDTA Vacuum Tubes
Product type: 5 mL EDTA vacuum tubes designed for veterinary blood sampling used in clinics, hospitals, and diagnostic labs. Commonly used in hematology workflows requiring anticoagulated samples. Best for labs that rely on standard 5 mL EDTA tubes and need consistent compatibility with phlebotomy procedures. Caution: verify tube compatibility with your existing analyzers and ensure proper handling to prevent hemolysis during collection.
Meterbox Micro Blood Collection Tubes 0.5mL EDTA K2
Product type: Non-vacuum 0.5 mL EDTA K2 tubes with purple screw caps. Premium polypropylene construction and a leakproof cap provide durability and safe transport. Best for small animals, poultry, or field work where compact tubes are advantageous. Limitation: non-vacuum design may require more direct handling during blood draw in some setups.
BD Sterile Venous Blood Collection Tube, Lavender
Product type: Lavender-top EDTA tubes, standard choice for complete blood counts and differential testing. Widely used in clinical laboratories for routine hematology assays. Best for labs seeking a widely accepted, ready-to-use EDTA tube with predictable performance. Limitation: may be more expensive per unit than bulk veterinary-specific options in some markets.
VNisenllc Pet Animals Lab Vacuum Blood Collection Tubes EDTA K2
Product type: Vacuum blood collection tubes designed for veterinary use with EDTA K2 as anticoagulant, aimed at accurate and reliable results in clotting tests in pets. Best for veterinary clinics and diagnostic labs needing robust vacuum tubes for coagulation-oriented workflows. Limitation: 10 mL capacity may be larger than some small-animal draw needs; ensure volume matches intended tests.
Buying Guide
What should you consider when buying EDTA tubes for veterinary or lab use?
- Volume needs: Choose 0.5 mL for small animals or pediatric cases, 5 mL for standard hematology, and 10 mL for larger animals or specific assays.
- Vacuum vs non-vacuum: Vacuum tubes support consistent draws and avoid overfilling; non-vacuum tubes offer flexibility for varied collection methods.
- Anticoagulant type: EDTA (K2 or K3) is standard for hematology; ensure the correct formulation for your analyzer and tests.
- Cap design and labeling: Purple or lavender caps indicate EDTA; ensure caps seal securely and packaging matches your workflow.
- Compatibility: Check tube dimensions, stopper material, and compatibility with your laboratory instruments and processing protocols.
- Durability and handling: For field or transport use, opt for leakproof caps and durable polypropylene tubes.
- Ventilation and safety: Consider biohazard handling needs and compliance with local regulations for storage and transport.
Frequently Asked Questions
- What is EDTA and why is it used in these tubes?
EDTA is an anticoagulant that prevents blood from clotting, preserving cellular components for accurate hematology testing.
- Which tube size should I choose for small animals?
- Are vacuum tubes better than non-vacuum tubes?
- Is lavender-top the same as EDTA K2 tubes?
- Can these tubes be used for coagulation testing?
0.5 mL tubes are often suitable for small animals or pediatric samples, while 5 mL is common for standard hematology panels.
Vacuum tubes provide consistent blood draws and reduce the risk of under- or over-filling, which improves test consistency.
Lavender-top typically indicates EDTA as the anticoagulant, commonly K2 EDTA, but verify the exact formulation with the manufacturer.
Some EDTA tubes (including certain 10 mL variants) are used in select coagulation protocols, but confirm compatibility with your coagulation assays.
