1.0 mL Sample Cups, Tethered Caps, HDPE, Natural, Hitachi/Roche Compatible — 127-1758-020 | 1,000/Bag | Caplugs® Evergreen

1.0 mL Tapered Flat Bottom Roche-Compatible Sample Cups with Tethered Caps — HDPE, Natural, 1,000/Bag

Technical Narrative

The Caplugs® Evergreen 127-1758-020 is a 1.0 mL tapered flat bottom sample cup with a permanently tethered hinged cap, precision-molded from virgin High-Density Polyethylene (HDPE) to the dimensional specification of Roche / Hitachi 717, 736, 737, and 747 autoanalyzer flat-bottom cup positions. 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.

HDPE 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.

At $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). Single-vendor procurement across all three colors eliminates compatibility risk when mixing cup batches on the same analyzer.

Technical Specifications — Caplugs® Evergreen

Roche / Hitachi Analyzer Compatibility —

The is engineered to the Roche / Hitachi tapered flat bottom cup specification. Primary compatibility:

The tethered cap must clear the analyzer's cup transport mechanism during rack loading. Validate cap clearance height against your instrument manual before large-volume purchase. Free samples available — see the procurement section below.

Chemical Resistance — High-Density Polyethylene (HDPE)

The is molded from virgin High-Density Polyethylene (HDPE). HDPE provides broader chemical resistance than PS, including better tolerance for concentrated acids and saline preservatives.

Clinical & Research Laboratory Applications

The tethered-cap sample cups serve hospital and reference laboratory Roche and Hitachi clinical chemistry analyzer fleets, STAT and high-throughput core laboratories where cap-loss events cause workflow disruption, clinical chemistry reference labs standardizing on tethered-cap format to eliminate loose cap management, outreach laboratory networks centralizing on Roche/Hitachi-compatible consumables, and biotech and pharmaceutical QC departments running open-system Hitachi-platform assays. The 1,000/Bag bulk format supports high-throughput processing at scale.

Frequently Asked Questions — Caplugs® Evergreen

Why choose a tethered cap cup over a standard open-top sample cup?

Tethered cap cups keep the cap physically attached to the cup body via a flexible hinge — the cap cannot be separated, lost, or mixed up between cups during high-throughput rack loading. On analyzers like the Hitachi 717/736 series where loose caps are a documented source of workflow delays and sample ID errors, tethered-cap formats reduce cap-management labor and contamination risk. The hinged cap closes securely after aspiration for sample archiving without requiring a separate loose cap to track.

Is the a direct replacement for Roche / Hitachi OEM cups?

The is engineered to the tapered flat-bottom cup dimensional specification used on Roche / Hitachi 717, 736, 737, and 747 analyzers and cobas c-series platforms that accept this cup format. As with all OEM-equivalent consumables, validate cup OD, height, tethered-cap clearance, and aspiration depth with your instrument manual and run a trial set before full-volume purchase. Free samples are available — see the procurement section below.

Are the cups BPA-free and phthalate-free?

Yes. Both the cup body and tethered cap are molded from virgin High-Density Polyethylene (HDPE) containing no BPA and no phthalate plasticizers — suitable for clinical chemistry, regulated laboratory, and accredited diagnostic environments.
