4.0 mL Freestanding Round-Bottom Autoanalyzer Sample Cups — HDPE, Natural, Hitachi/Roche Compatible (127-0017-020)
These 4.0 mL freestanding autoanalyzer sample cups are precision-molded from virgin High-Density Polyethylene (HDPE) for direct placement in clinical chemistry analyzer rack systems, supplied non-sterile in sealed bags of 1,000. The round-bottom geometry ensures complete probe aspiration down to dead-volume minimums, reducing partial-sample errors during high-throughput clinical chemistry panels. HDPE construction offers superior chemical resistance compared to polystyrene, making these cups the preferred choice for aggressive reagent chemistries, elevated-temperature incubations, and extended sample hold times.

Applications
- Clinical chemistry autoanalyzer sample loading in open-system cup positions
- High-throughput reference laboratory panels requiring minimal dead-volume aspiration
- Hospital and clinical laboratory chemistry analyzers running routine metabolic, lipid, hepatic, and renal panels
- Biotech and research workflows requiring freestanding HDPE sample cups compatible with standard autoanalyzer racks
- Extended sample hold and incubation workflows where polystyrene cup integrity may be a concern
Compatibility
The round-bottom freestanding geometry of these cups is designed for open-system sample cup positions across a broad range of clinical chemistry analyzers. Validated deployment configurations include Hitachi/Roche 717, 736, 737, 747, 911, and 917 analyzers (round-bottom standard rack) — the most common deployment for this cup style. Additional compatible platforms include the Roche Diagnostics COBAS MIRA and COBAS Integra 400/700/800 (open-system configuration), Olympus/Beckman AU400, AU600, AU640, and AU2700, Beckman Coulter CX3, CX4, CX5 Delta, and DxC 600i/700i/800, Siemens Dimension RxL, XL, and Vista 1500/3000, Abbott Diagnostics Architect c4000, c8000, and c16000, and Mindray BS-200, BS-300, and BS-400 series. Because rack configurations and aspiration-depth specifications vary by instrument model and site configuration, always validate cup seating, rack fit, and aspiration depth against your specific instrument setup before placing a bulk order.

Chemical Resistance
| Reagent / Condition | Compatibility |
|---|---|
| Aqueous buffers and saline | Excellent |
| Dilute acids and bases | Excellent |
| Alcohols (methanol, ethanol, isopropanol) | Good — suitable for most clinical concentrations |
| Serum, plasma, and whole blood | Excellent |
| Clinical chemistry reagent chemistries | Excellent — superior to polystyrene for aggressive reagents |
| Chlorinated solvents (chloroform, DCM) | Not recommended |
| Aromatic solvents (toluene, xylene) | Not recommended |
| Elevated-temperature incubation | Good — more stable than polystyrene under heat |
Quality & Procurement
Made in USA at Caplugs® Evergreen's California manufacturing facility, these cups are molded from virgin HDPE resin under strict dimensional quality control protocols that deliver consistent seating tolerance and wall-thickness lot after lot — the reliability that procurement teams at reference laboratories and hospital systems require for uninterrupted high-throughput operations. Every cup is BPA-free and free of phthalate plasticizers. The sealed 1,000-count bag format maintains cleanliness from stockroom to point of use without secondary packaging, and the freestanding base integrates directly into existing autoanalyzer rack systems without additional holders or inserts. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping from USA inventory, with tiered pricing available for institutional and high-volume accounts.
Frequently Asked Questions
Are these autoanalyzer cups sterile?
No — they are supplied non-sterile in sealed 1,000/Bag packaging, which is standard for open-system clinical chemistry autoanalyzer sample cups used on instrument platforms that do not require sterile consumables.
Why choose HDPE over polystyrene for autoanalyzer sample cups?
HDPE offers superior chemical resistance compared to polystyrene, making these cups better suited for analyzers running aggressive reagent chemistries, elevated-temperature incubations, or workflows with extended sample hold times where PS cup integrity may be compromised. For applications where polystyrene is preferred, other members of the 127-0017 family are available in PS in multiple colors.
How do I confirm these cups will fit my specific analyzer?
The round-bottom freestanding geometry is compatible with open-system cup positions on a wide range of platforms including Hitachi/Roche, Roche COBAS, Olympus/Beckman, Siemens Dimension, Abbott Architect, and Mindray BS series analyzers — but rack configurations and aspiration depths vary by model and site setup. Always validate cup seating, rack fit, and aspiration depth on your specific instrument before bulk ordering. Contact LabSupplies.com to request validation samples.
What is the dead volume of these cups?
The round-bottom geometry is specifically designed to minimize dead volume and ensure complete probe aspiration, which reduces costly partial-sample errors in high-throughput panels. Exact dead-volume figures are instrument-dependent and should be confirmed during your validation run.
