The tethered cap design is the key differentiator: the cap remains physically attached to the cup body at all times — eliminating cap-loss events during high-throughput rack loading and unloading that cause delays, sample identification errors, and contamination risks on busy clinical chemistry processing benches.\u003c\/p\u003e \u003cp\u003eHDPE construction provides superior chemical resistance over Polystyrene for aggressive reagent applications, with excellent compatibility across saline buffers, dilute acids, EDTA, and standard clinical chemistry preservatives. The blue color-coding integrates into color-sorted specimen staging and processing-lane identification on busy clinical chemistry benches. HDPE's natural rigidity maintains the tapered flat-bottom geometry under centrifugation and rack handling forces, ensuring consistent aspiration depth and dead-volume minimization across all 1,000 cups in the bag.\u003c\/p\u003e \u003cp\u003eAt $51.92 per 1,000-count Bag — $0.0520 per cup — the delivers Roche\/Hitachi-compatible tethered-cap cup quality at bulk procurement pricing.
