Brand Cuvets PMMA 45 x 12.5mm 759105

Macro and semi micro cuvettes
Sorted by mould cavity number. PMMA or PS.
What does *sorted by mould cavity number* mean? Injection moulds which produce 8 cells in one cycle have 8 cavities. For serial analysis only cells with the same cavity number should be used, to minimise cell-to-cell variation.
Quality characteristics:
-Minimal extinction value variation.
-Optically perfect transmission range
-Recessed window, to protect against scratches
-Arrow head marking shows the direction of transmission.

Advantages to user:
-Ideal for kinetics measurements
-1000 cells from the same cavity in each pack
-Practical packaging: clear, re-closable.

Polymethylmethacrylate (PMMA) cuvettes
Typical operating range: from 300nm to 900nm.
Standard deviation at 320nm ± 0.004 extinction units.

Polystyrene (PS) cuvettes
Typical operative range: from 340nm to 900nm.
Standard deviation at 360nm ≤ ± 0.005 extinction units.

Macro cell with 4 optical windows, PS / UV-transparent
