K3 Edta Tube Price — a buyer’s snapshot from the lab floor

I’ve toured more than a few consumables lines in North China, and, to be honest, EDTA microtubes remain one of the quiet workhorses of hematology. The EDTAK3 Tube from 9-1-701 TonfuTown, Shijiahzuang City, Hebei Province, China is pitched squarely at OEM buyers who want private labeling without drama — and yes, the K3 Edta Tube Price can be surprisingly competitive if you know which levers to pull (MOQ, sterilization route, and cap color customization, mainly).

Industry trends (quick take)

Demand for K3 EDTA microtubes tracks with point-of-care and pediatric collections. Post-pandemic logistics nudged buyers toward dual-certified suppliers (ISO 13485 + CE/IVD). Many customers say they’re prioritizing vacuum accuracy and additive consistency over the absolute lowest K3 Edta Tube Price because repeat draws are costlier than a cent saved.

Process and materials (how it’s really made)

Typical build: PET tube body, polypropylene cap (lavender), butyl rubber stopper; tripotassium EDTA (K3) is spray‑dried or liquid‑dosed then dried to ≈1.5–2.2 mg EDTA/mL of nominal blood draw. Vacuum forming ensures fill volume, then tubes are EO-sterilized or gamma-irradiated (suppliers validate to ISO 11135/11137). QC checks: vacuum tolerance (≈±10%), additive mass (gravimetric/UV), closure integrity, and anticoagulation efficacy on control blood. Shelf life is commonly 24 months at 4–25°C, real-world use may vary.

Applications & notes

Use for CBC, HbA1c, and general hematology. Some lab directors prefer K2 EDTA for cell morphology; K3 is still common in micro-collection where immediate anticoagulation is the priority. In pediatric wards and home-testing kits, these tubes reduce redraws. One buyer told me “vacuum stability and clean stoppers” mattered more than shaving 0.003 USD off the K3 Edta Tube Price.

Price factors (what really moves the needle)

• MOQ tiers: 10k, 50k, 200k+ pcs; price can drop ≈15–30% across tiers.
• Sterilization: gamma often adds ≈3–6% vs EO.
• Customization: cap color, private label, pouching; add ≈0.002–0.01 USD/tube.
• FOB North China microtube ballpark: ≈0.025–0.060 USD/tube, depending on spec and volume.

Vendor snapshot (comparative)

Case note: mid-size lab switch

A 300-bed hospital lab moved to OEM microtubes with private labeling. Over six months, unit cost fell ≈18%, while fail rates (underfill/hemolysis linked to stoppers) dropped from 0.9% to 0.4% after tightening incoming QC. Not flashy, but real money. That’s why negotiators watch both QC data and the K3 Edta Tube Price.

What to request before PO

• COA showing additive mass and vacuum tolerance; sample test data across 3 lots.
• Certificates: ISO 13485, CE/IVD DoC; sterilization validation summary (11135/11137).
• Conformance to ISO 6710; user procedures aligned with CLSI GP41.
• Shelf-life study (accelerated/real-time) and packaging transit tests (ISTA/ASTM).
