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 clear natural HDPE enables direct visual sample volume assessment and optical clarity for photometric autoanalyzer measurement. 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. The 127-1758 family is available in three colors for color-coded workflow integration: 127-1758-B20 (HDPE Blue, $51.92\/Bag); 127-1758-Y20 (HDPE Yellow, $51.92\/Bag).
