This type 46 semi-micro cuvette is a reduced-volume screw cap cell. The open SEPTA screw cap enables researchers to make sterile injections into the cuvette without compromising the experiment. Contains a 10 mm lightpath with various inner widths available ranging from 1 to 5 mm. This enables the researcher to choose different volumes. Screw cap and silicon/PTFE septa provide the tightest seal available so gases and liquids will not leak out. Suitable for anaerobic work.
