Import Blood Collection Tube — Buy in wholesale FOB from Supplier in China

Laiwu Yaohua Pharmaceutical Packing Co. Ltd. manufactures vacuum blood collection tubes across nine additive configurations, covering the full diagnostic panel from basic serum chemistry to specialised coagulation and erythrocyte sedimentation testing. The tube range includes: plain serum (red cap), clot activator (orange cap), SST gel separator (yellow cap), glucose preservative (grey cap), sodium citrate 1:9 (blue cap), sodium or lithium heparin (green cap), EDTA K2/K3/Na2 (lavender cap), ESR 1:4 (black cap) and a dedicated 1.28ml glass ESR tube (black cap). Material options are PET plastic or borosilicate glass, with more than fifteen years of manufacturing experience claimed. The supplier holds ISO 13485 and CE certification for this product line.

The sodium citrate 1:9 ratio (typically 3.2% trisodium citrate) in the blue-capped tube is critical for coagulation assays including prothrombin time and activated partial thromboplastin time, where anticoagulant-to-blood ratio must remain exact to prevent false prolongation or shortening. Heparin tubes (green cap) contain either sodium or lithium heparin as anticoagulant for plasma chemistry, with lithium heparin preferred for certain ionised calcium and enzyme assays to avoid sodium interference. The EDTA formulations (lavender cap) use dipotassium, tripotassium or disodium salts for haematology, with K2EDTA now preferred over K3 due to reduced osmotic effect on cellular morphology. The 1.28ml glass ESR tube follows the Westergren method specification with 1:4 citrate-to-blood dilution, distinct from the standard black-capped 1:4 ESR tube in volume and material.

Export markets listed include Europe, Russia, Middle East, South East Asia, East Asia, South Asia and South America, indicating broad regulatory familiarity across IVD directive and emerging market frameworks. Laboratories, hospital systems, diagnostic reagent distributors and pharmaceutical clinical trial suppliers are typical buyers. The supplier does not state MOQ, price bands, lead times or Incoterms in the source material, so buyers must confirm these commercially sensitive terms directly with Laiwu Yaohua Pharmaceutical Packing Co. Ltd. Packaging configuration for international shipment is also unspecified and should form part of initial technical and commercial discussions.

Laiwu Yaohua Pharmaceutical Packing Co. Ltd. is located at East First of Canglongquan Street, Laiwu, Shandong 271100, China. The company holds a 'harbor' trust tier with a 0.00% response rate and zero recorded average response hours, suggesting limited or unmonitored platform messaging. Buyers should not rely on rapid digital response and should establish direct contact channels early in the sourcing process. The Shandong location places the supplier within a province with established pharmaceutical and medical device manufacturing infrastructure, though this does not by itself confer quality assurance.

The source material states over fifteen years of product development and manufacturing experience, ISO 13485 and CE certification, and export activity across multiple continents. No information is provided about factory floor area, employee count, annual production capacity, named OEM clients or revenue figures. The company name references pharmaceutical packing, which may indicate broader primary packaging capabilities beyond blood collection tubes. Buyers should request a facility overview, quality manual summary, regulatory registration list and customer reference letters to substantiate the experience and certification claims before committing to volume orders.
