Globe Scientific Cobas Mira Racked Cuvettes — PMMA, 12-Place Segments, 15 Racks/Unit (5123)

Globe Scientific Cobas Mira Racked Cuvettes (5123) are 12-place PMMA cuvette segments designed for use on the Roche Cobas Mira, Mira S, Mira Plus, and Horiba ABX changer clinical chemistry analyzers. Each unit contains 30 racks of 15 cuvette segments — 450 segments total — pre-loaded in rack format for direct placement into the analyzer's cuvette loading bay. This racked format eliminates the individual segment handling that slows throughput during high-volume chemistry runs.

Racked vs. Individual Cuvette Segments

Globe Scientific offers Cobas Mira cuvettes in two formats: individually wrapped segments (5120/5121) and racked segments (this product, 5123). The racked format is designed for laboratories running continuous daily chemistry workloads where the analyzer's cuvette supply must be replenished quickly and without interrupting the run queue. Each rack slides into the analyzer's loading position as a unit — 15 segments loaded in one motion instead of 15 individual insertions. For lower-volume labs that run intermittent batches, the individually wrapped format may be more practical since segments stay sealed until needed.

PMMA Optical Quality

Polymethylmethacrylate (PMMA) provides the UV-visible light transmittance that clinical chemistry photometers require for accurate absorbance measurements. Each cuvette segment is molded to consistent wall thickness and optical path length tolerances, ensuring reproducible readings across the full segment. The PMMA material is compatible with the wavelength ranges used by the Cobas Mira platform for general chemistry, enzyme, substrate, and immunoturbidimetric assays.

Analyzer Compatibility

These cuvettes are manufactured as a third-party alternative to OEM Roche and Horiba ABX consumables. They are dimensionally and optically compatible with the following analyzer models:

• Roche Cobas Mira

• Roche Cobas Mira S

• Roche Cobas Mira Plus

• Horiba ABX changer analyzers

If your laboratory operates a Horiba ABX Mira S Plus or Pentra 400 analyzer, see Globe Scientific 5162 instead — the cuvette segment geometry differs between these platforms, and using the wrong format can cause loading jams or alignment errors.

Third-Party OEM Alternative

Analyzer consumables are a recurring cost that scales directly with test volume. Laboratories processing hundreds of chemistry panels daily consume cuvette segments at a rate that makes per-segment pricing a meaningful line item in the consumables budget. Globe Scientific cuvettes provide the same PMMA material quality and dimensional specifications as OEM segments at below retail pricing — reducing per-test consumable costs without affecting analytical accuracy or analyzer function.
