Frequently Asked Questions
Which analyzers are these cuvettes compatible with?
These PMMA cuvettes are designed for the Cobas Mira, Mira S, and Mira Plus clinical chemistry analyzers, fitting their reaction rotor format.
Why are the cuvettes individually wrapped?
Individual wrapping protects the optical surfaces from dust, fingerprints, and scratches, helping ensure consistent absorbance readings until the moment of use.
What is the difference between SKU 5121 and SKU 5120?
The difference is pack quantity only: SKU 5121 contains 300 cuvettes per case, while SKU 5120 contains 500 cuvettes per case. Both share identical PMMA construction.
Are these cuvettes supplied sterile?
No. The cuvettes are non-sterile disposable consumables intended for in vitro clinical chemistry applications and are used once before disposal.
