Particles size analysis of small and precious samples with the wet disperser CUVETTE inserted in the measuring zone of HELOS, shown is the 50ml cuvette module with the ultrasonic finger with adjustable power on top.

Technical specifications and dimensions.

The CUVETTE is a wet dispersing system for HELOS and is specially designed for particle size analysis of suspensions and emulsions with small sample volumes of less than 50 ml (CUV-50ML/US) or 6 ml (CUV-6ML/SM).

Its cuvette is only made out of high quality optical glass and no glue has been used for its construction, so any contamination of the suspension or emulsion is strictly avoided. The sample is completely conserved for future use, which makes this device to an ideal choice for expensive and/or pharmaceutical samples.

The CUVETTE consists out of three modules:

CUV-CHASSIS:	This is the basis for the subsequent units containing the electronics and the drive for the magnetic stirrer.
CUV-50ML/US:	This add-on to CUV-CHASSIS has a 50 ml cuvette and a software controlled magnetic stirrer coated with PTFE. An integrated sonication finger made from Titanium can be lowered manually into the cuvette. Its power can be adjusted by software from 0 to 60W in steps of 1%. The recommended measuring range is R2 to R7 (0.25 µm to 3500 µm).
CUV-6ML/SM:	This add-on to CUV-CHASSIS has a 6 ml cuvette and manual operated stirrer frame coated with PTFE. The recommended measuring range is R1 to R2 (0.1 µm to 87.5 µm).
