VariPol – Polarimeter
Modular Polarimeter for Pharma & more
The SCHMIDT + HAENSCH VariPol is the newest and fastest generation of precision polarimetry. It is especially designed for pharmaceutic applications, but it can be adapted to further uses. Its unrivaled precision in measurement is paired with modularity, flexibility, and rapidity. State-of-the-art connectivity allows for seamless integration into your extended network of devices and permits monitoring your measuring results using our Aquisys Software on your phone or tablet.
ID-N° 31009 (multiple variations in specifications below)

Easy to use
Our sample tubes’ tension-free design allows fast cleaning and permits exchange of cover glasses without birefringence. The seamless sample chamber has no dead space allowing fast rinsing without deposits. The rotatable sample tubes and quartz standards allow you to check quickly and easily their cleanliness and correct performance. The instrument, as well as tubes, quartz plates, and accessories are all made in Germany to ensure the quality and performance you are expecting from SCHMIDT + HAENSCH. Together with a gear-free polarization detection you have the constant SCHMIDT + HAENSCH precision over the whole measurement range.
Applications
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. Documenting GLP and GMP is possible with the VariPol. The VariPol is adaptable in numerous medical, chemical, and sugar applications as wavelength modules can be exchanged to allow a flexible operation
Product in detail
The new, sophisticated design is nearly half the size of our earlier models and is packed with new features and highly integrated hardware. The SCHMIDT + HAENSCH expertise of over more than 150 years in polarimetry is reflected in all components like the fortified aluminum core, the built-in quality indicator of samples, as well as the check of calibration standards. The new integrated peltier system can change 10 °C in 30 seconds to highest precision. After stabilization of the temperature the measurement itself takes only 6 seconds. Optimized electronic components result in a low power consumption and, together with a modern standby mode, the VariPol delivers fast reaction times and helps to preserve resources.
Thanks to our LED light technology the light source is maintenance free during the instrument’s lifetime, saving you maintenance costs and downtime.
