Configuration Options
Different laboratories and distributors may require different combinations of tube volume, citrate concentration and packaging. We can discuss the required configuration before production to avoid unnecessary changes after ordering.
Available options can include:
- 3.2% or 3.8% sodium citrate
- Different tube volumes according to product configuration
- Different labeling and carton requirements
- OEM / private label packaging
- Customized quantities for distributor orders
Please contact us with your target market, required specification and estimated order quantity. We can check the available configuration before quotation.
Quality & Production Control
Blood collection tubes require consistent production conditions because tube performance depends on several factors, including the tube, additive, vacuum and packaging.
Our production process is managed under an ISO 13485 quality management system. Batch traceability is maintained for production and quality control, supporting routine supply for medical distributors and laboratory product suppliers.
Before bulk orders, customers can request samples to evaluate the tube configuration and packaging with their own laboratory or purchasing team.
Built for Distributor Supply
For distributors, the advantage is not only the individual tube specification but also the ability to source related blood collection consumables from one manufacturer.
Along with ESR tubes, our product range includes EDTA, serum, gel & clot activator, heparin and other routine blood collection tubes, as well as straight needles and butterfly needles.
This allows distributors to combine several related consumables in one sourcing program instead of managing multiple suppliers.

| Slender ESR Tube (4:1) |
The ESR tube uses a 4:1 blood-to-anticoagulant ratio. Sodium citrate tubes for coagulation testing use a different 9:1 ratio and are supplied as a separate product series.
