Hitachi sample cup

The primary material used should be medical-grade ultra-clear polystyrene (PS). This ensures high transparency for accurate optical testing and chemical resistance to common reagents. The cups must be free of burrs, bubbles, and impurities to prevent interference with the analyzer's sensors.

You must verify that the dimensions strictly adhere to the standard 2ml or 1.5ml specifications used by Hitachi 7060/7150/7600 series. Ensure the conical bottom design is optimized for low dead volume, allowing the probe to aspirate the maximum amount of sample without air bubbles.

Suppliers should ideally hold ISO 13485 certification for medical device quality management. For international trade, ensure the products are CE marked and comply with FDA regulations if shipping to the US. Request a Certificate of Analysis (CoA) for each batch to confirm sterility and material purity.

Key benchmarks include centrifugal stability (ability to withstand high speeds without cracking) and thermal stability during refrigerated storage. The rim design must be precise to allow for secure sealing with caps or film to prevent evaporation and cross-contamination.

Sample cups are lightweight but brittle. Insist on double-corrugated export cartons and internal polybag lining to prevent dust contamination. For large volumes, palletization with shrink wrap is essential to minimize manual handling shocks during transit.

Focus on mold precision and consistency. Ask for the cavity number of the mold; high-quality suppliers use multi-cavity molds that ensure uniformity across millions of units. Negotiate based on annual volume rather than single orders to secure a 10-15% price reduction.

Prioritize Audited Suppliers who have undergone on-site inspections by third parties like SGS or Intertek. Check their export history to your specific region and request actual production photos of the cleanroom facilities (Class 100,000 cleanroom is preferred).

Use Secured Trading services provided by Made-in-China.com to ensure payment is only released upon confirmation of shipment. Always request a pre-shipment sample from the mass production batch to verify that the quality matches the initial prototype.
