Easy to use

The sample tubes’ tension-free design allows fast cleaning. Cover glasses can be exchanged without causing birefringence. The seamless sample chamber has no dead space, which allows for quick rinsing without leaving any deposits.

The rotatable sample tubes and quartz standards let you quickly check their cleanliness and proper performance. The instrument, tubes, quartz plates, and accessories are all made in Germany to ensure expected SCHMIDT + HAENSCH quality.

Applications

The VariPol has a 100 mm sample chamber and is ideal for pharmacological applications. It complies with the International Pharmacopoeia, 21 CFR Part 11 and OIML. The VariPol is adaptable for medical, chemical, and sugar applications. Its wavelength modules is exchangable to enable flexible operation.

The modular polarimeter in detail

SCHMIDT + HAENSCH’s 150+ years of polarimetry expertise is evident in every detail: from the reinforced aluminium core to the built-in sample quality indicator and calibration standard check.

The new integrated Peltier system adjusts temperature by 10 °C in just 30 seconds with high precision. Once stabilized, the measurement takes only 6 seconds. Optimized electronic components and a modern standby mode reduce power consumption, enable fast reaction times, and support resource conservation.
