This simple fitting screws into one of the accessory holders on the side of the qpod. Insert the end of a probe into the fitting, place it the desired distance from the face of the cuvette, and gently tighten set screws to hold it in place. To use this fitting, the length of the cylindrical active end of the probe plus the distance from the end of the probe to the cuvette must be at least 2 inches. This is sometimes not the case for the commonly used InPhotonics probe. Regardless, we can accommodate nearly any Raman probe, although some will require significant modifications to the qpod.
