The NEW VariPol C

The new VariPol C from Schmidt + Haensch is a basic Polarimeter which is especially designed for pharmaceutical applications. It offers a high quality build-in peltier system for automatic temperature control.

Furthermore it is very easy to calibrate with the integrated Automatic Wavelength Control (AWC+), permits energy saving durable LED’s and wireless automatic identification of sample tubes via RFID.

The VariPol C is 21 CFR part 11 ready and the appropriate Software Aquisys 2008 could be purchased optionally.

Applications often used
  • Determination of concentration
  • Purity analysis
  • Quality control
  • Scientific analysis
  • Pharmaceuticals (alkaloids / amino acids / organic compounds / vitamins / essential oils / antibiotics / serums)
  • Chemicals (organic fluids / biopolymers / synthetic and organic polymers / benzene / acids / esters etc.)
  • Research (analysis of molecular structure / investigation of kinetic reactions as function of time / distinction of optical isomers / monitoring changes in concentration of an optically active component in a reaction mixture as in enzymatic scission)
