THORLABS 4P20 Cuvette Holder Port Insert
General Information
Description
Thorlabs’ 4P20 cuvette port insert holds cuvettes inside our 4P3 and 4P4 Ø100 mm Modular Integrating Spheres. The cuvette port insert is designed to hold a 12.5 mm x 12.5 mm cuvette with a 10 mm path length (sold separately). Cuvettes with or without caps can be used to analyze liquid samples with the cuvette in an upright position.
Operation
The 4P20 insert consists of two parts: a cuvette holder and a base to secure the cuvette holder into the integrating sphere.
Mounting the Insert on the Integrating Sphere
To mount the 4P20 cuvette port insert on the top side of the 4P4 or 4P3
integrating spheres, remove the 4P10 port plug from the top position of the
sphere and replace it with the 4P20 cuvette port insert. Secure the 4P20
insert to the integrating sphere using the two included M3 x 0.5, 8 mm long
cap screws.
Cuvette Holder
The cuvette is inserted into the cuvette holder from below by following the
steps illustrated in Figure 2. First, lift the cuvette holder from the base.
With the cuvette holder in one hand, pull and hold the safety catch with your
index finger like a trigger. Then, push the release button down with your
thumb and slide the cuvette up into the holder. Release both buttons to secure
the cuvette. The holder can now be placed back into the base.
Rotating the Cuvette
Use the release button on the cuvette holder to coarsely rotate the cuvette to
any angle. The rotational position can be fixed with the 8-32 locking set
screw on the side of the cuvette holder. Please do not fasten the set screw
too tight to avoid deformation of the soft holder material.
Height Adjustment of the Cuvette Inside the Integrating Sphere
The height at which the cuvette is positioned in the integrating sphere can be adjusted at the base of the insert. Hold the top part of the base while loosening the M4 setscrew shown below. Carefully slide the cuvette holder and top part of the base down. The vertical scale on the insert base will adjust. Once the desired position is reached, tighten the M4 setscrew lightly.
Attention
Do not loosen any screws other than those indicated as this will damage the
4P20 cuvette port insert and the integrating sphere.
Cuvette Replacement
The base of the 4P20 insert can remain attached to the Integrating sphere while the cuvette holder is removed and reinserted. The cuvette height and rotation inside the integrating sphere will stay the same. Slide the cuvette holder upwards out of the 4P20 base. To remove the cuvette, first push the safety catch and then the release button as described above. With both pushed in, the cuvette can be removed from the cuvette holder. To insert a new cuvette, please follow the instructions above. If a cuvette with a cap is used, it is recommended to use cuvettes with airtight stoppers, since PTFE top caps tend to get stuck in the port Insert. A cuvette without a cap is held in place by eight Ø3 mm glass balls. If a cap with a maximum height of 10 mm is used, the cuvette will still be held in place with four of the glass balls.
