1.0 mL Conical Flat-Bottom Sample Cups — Alfa Wassermann® ACE Analyzer Replacement, PP, Natural (127-5300-030)
These 1.0 mL polypropylene sample cups feature a conical flat-bottom geometry dimensioned for the sample-cup carrier positions on Alfa Wassermann® clinical chemistry analyzers, providing a consistent aspiration geometry that minimizes positional error across a full carousel load. Supplied non-sterile in 1000/Bag packaging, they serve as a direct OEM-format replacement for labs running Alfa Wassermann® ACE-platform instruments in routine chemistry, therapeutic drug monitoring, and reference-testing workflows. The natural (translucent) color allows visual confirmation of sample presence and volume without removing the cup from the carrier.

Applications
- Routine clinical chemistry on Alfa Wassermann® ACE-platform analyzers (serum, plasma, and urine panels)
- Therapeutic drug monitoring (TDM) workflows requiring precise small-volume aspiration
- Reference laboratory and send-out testing where consistent sample cup geometry is critical
- Manual bench aliquoting in standard 13 mm cup rack positions
- Enzyme-substrate and protein-chemistry assays benefiting from low-protein-binding PP surfaces
Compatibility
These cups are dimensioned as a direct OEM-format replacement for the sample-cup carrier positions on Alfa Wassermann® clinical chemistry platforms, including the ACE, ACE Alera, ACE Clinical, and ACE Axcel analyzer families. The conical flat-bottom profile seats precisely in the analyzer carrier, presenting a repeatable aspiration point to the probe across an entire carousel run. Labs evaluating use on the Alfa Wassermann® Viva-E Drug Testing System or on compatible 13 mm cup positions across various Hitachi/Roche-lineage instruments should verify dimensional fit against their specific carrier configuration before standardizing. Confirm cup position geometry on any non-standard carrier before placing a full institutional order.
Chemical Resistance
| Reagent / Sample Type | Compatibility | Notes |
|---|---|---|
| Saline (0.9% NaCl) | Excellent | Routine diluent; no observed effect |
| Aqueous buffers (PBS, Tris, HEPES) | Excellent | Compatible across pH 4–10 |
| Dilute acids (HCl, H₂SO₄, <10%) | Good | Suitable for routine analyzer wash cycles |
| Dilute bases (NaOH, KOH, <10%) | Excellent | PP outperforms PS for caustic exposure |
| Ethanol / Methanol (<70%) | Excellent | Compatible for short-contact applications |
| ISE diluents and enzyme-substrate reagents | Excellent | PP is inert to standard ACE-platform chemistry reagents |
| Acetone / chlorinated solvents | Not recommended | May cause crazing or dimensional change |
Quality & Procurement
Made in USA, these Caplugs® Evergreen sample cups are manufactured from FDA-compliant, food-contact-grade polypropylene under ISO 9001 quality management, and are certified BPA-free, phthalate-free, and latex-free. The low-protein-binding PP resin preserves analyte recovery in small-volume sample applications, and the material is thermally stable under typical analyzer incubation deck conditions. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping directly from USA inventory, with same-business-day dispatch typical for stocking SKUs; volume pricing and institutional account terms are available for multi-bag orders.
Frequently Asked Questions
Are these sample cups sterile?
No — they are supplied non-sterile. For routine clinical chemistry and TDM workflows on closed analyzers, sterility is not required; if your protocol mandates sterile consumables, please contact us for guidance on available options.
Will these cups fit Alfa Wassermann® analyzers other than the ACE series?
The conical flat-bottom geometry is dimensioned for the ACE, ACE Alera, ACE Clinical, and ACE Axcel carrier positions. Fit on the Viva-E Drug Testing System and on Hitachi/Roche-lineage instruments with compatible 13 mm positions should be verified dimensionally before standardizing to these cups across your fleet.
Why is polypropylene the preferred material for these analyzer cups?
Polypropylene is inert to the aqueous buffers, ISE diluents, protein-chemistry reagents, and enzyme-substrate systems typically run on ACE-platform analyzers. Its low protein-binding surface helps preserve analyte recovery in small-volume cups, and it withstands the thermal environment of the analyzer incubation deck better than polystyrene alternatives.
What quantity should I order for high-volume laboratory operations?
Each bag contains 1,000 cups. Laboratories running multiple analyzer shifts or high daily sample volumes should consider multi-bag orders to take advantage of volume pricing and reduce per-cup cost; institutional account terms are available — contact our procurement team for a quote.
