Using the cuvette holders
Square cuvettes
- simply slide the square cuvette into the square cuvette holder.
If the cuvette has frosted sides these should face the front and rear of the instrument.
The beam passes through the sample compartment from right to left so the clear faces
of the cuvette must be on the right and left sides.
Test-tube cuvettes
- The screw clamp only needs to be adjusted once for a particular size of
test tube.
1. Loosen the thumb-screw and place the test tube cuvette in the holder.
Home: Takes the user directly to the Home menu from any point in the
software.
Print: Prints an exact copy of current screen.
Wavelength knob: Set the wavelength by rotating the wavelength knob.
Turning the knob without pressing down changes the wavelength in 10 nm
increments. For fine wavelength control (1 nm increments) press the
λ
knob
down and rotate.
