Measure cell fluorescence without a
microscope
Newly developed coverslip holder allows standard coverslips to be located in a fluorescence cuvette in a defined orientation to the excitation beam
One way of measuring the fluorescence of cultured cells often described in the literature is on a coverslip inserted into a conventional fluorescence cuvette However the practical difficulties of securely and accurately aligning the coverslip combine to make the technique difficult and imprecise

CRMs for far-UV validation
Certified reference materials extend the instrument qualification range to 200nm, unlike most commercially-available UV CRMs which have lower limits around 240nm
It is also virtually impossible to mix the cell contents because the coverslip is resting on the bottom of the cell.
A newly developed coverslip holder from Starna overcomes these problems.
With this device, standard (11x22mm) coverslips can be easily and reproducibly located in a fluorescence cuvette in a defined orientation of 45deg to the excitation beam.
The coverslip is mounted so that it is located centrally in the optical beam, typically at 15mm from the base of the cuvette.
In this position there is space below the coverslip for a small stirrer bar to facilitate mixing the cell contents.
In addition the design allows for solution introduction using a syringe injection port or media exchange for perifusion experiments.
The holder is manufactured in inert black PET (polyethethylene terephthalate).
