SAC Temp Controller

Control temperature easily!
Temp Controller 3 Main Points:

Reliability

Stability

Reproducibility

Controlling and stabilizing sample liquid temperature during measurement produces more accurate measurement results in accordnace to Japanese Pharmacopoeia / Food Additives Official Regulations.

The reproducibility of optical rotation measurement results

All samples can be set at and measured at the specified temperature (20 °C).
By controlling and stabilizing the measurement temperature, it is possible to eliminate measurement variations due to temperature variations and improve the reproducibility of optical rotation measurement results.

Improved Reproducibility 95%
