VariPol Series
Digital Polarimeter
The VariPol Series is the newest and fastest generation of precision digital polarimetry, especially designed for pharmaceutical applications and 21 CFR Part 11 ready. Its integrated Peltier system changes temperature by 10°C in just 30 seconds, with measurement itself taking only 6-8 seconds once stabilised.
Digital Polarimeter
The SCHMIDT + HAENSCH VariPol is the newest and fastest generation of precision polarimetry. Especially designed for pharmaceutic applications, it can be adapted to further uses. Its unrivalled precision in measurement is paired with modularity, flexibility and rapidity. State-of-the-art connectivity allows seamless integration into your extended network of devices and permits monitoring your measuring results using the Aquisys Software on your phone or tablet.
With a 100mm sample chamber, the VariPol is designed especially for pharmacological applications and provides compliance with the International Pharmacopoeia, 21 CFR Part 11, OIML and Australian Standard K57. The VariPol is adaptable for numerous medical, chemical and sugar applications as wavelength modules can be exchanged for flexible operation.
