Direct Attach Cuvette Holders – CUV-DA

Avantes provides a variety of direct-attached cuvette holders to mount a cuvette holder directly to one’s light source. The CUV-DA connects to the AvaLight-DHc, -XE and -LED light sources, the CUV-DA-DHS connects to the AvaLight-DHS and AvaLight-DHS-BAL, and the CUV-DA-HAL-Mini connects to the AvaLight-HAL-Mini. These devices can be used for either fluorescence or absorbance measurements.

All CUV-DA cuvette holders have two 90-degree and one 180-degree threads that allow the COL-UV/VIS collimating lens to be connected for fluorescence or absorbance arrangements. Each of CUV-DA series cuvette holders includes two SiO2 aluminum mirrors to additionally enhance fluorescence signals. These are mounted at 90 degrees to the excitation source and emission output. The CUV-DA consists of a 5 mm wide filter slot.

For the AvaLight-HAL and the AvaLight-DHS, the direct-attached cuvette holders can be mounted straight onto the front panel of the light source by taking off the standard filter holder.
