PHÂN CỰC KẾ CHO NGÀNH DƯỢC & HÓA CHẤT
Model: Unipol L Series
NSX: Schmidt Haensch - Đức
Phân cực kế tự động, thiết kế đặc biệt cho ngành dược phẩm, thực phẩm, hóa chất
NEW: Polarimeter UniPol L series now without separate electronic unit for T-Cells! All models of the UniPol L “P” series are now completely ready to be used with our peltier tubes! The other standard models (Unipol 589, UniPol 1000 and UniPol 2000) can also be easily upgraded to a Peltier version. To upgrade an existing UniPol a peltier main board has to be purchased and built into the standard UniPol by a technician at the costumer’s site.
The entire measuring range of ± 360° is divided in several measuring ranges which can easy be selected by the menu.
The user friendly menu structure of the instrument is easily operated with the splash-proof alphanumerical keyboard. Software design close to the practise enables the user to input sample ID-numbers, calculate statistical evaluation and configure user defined printout of the measuring results. The measuring values are shown on the large LCD display.
The standard model is equipped with the 589 nm wavelength. Other wavelengths on request.
Various polarimeter tubes are available for different applications. With the use of micro tubes smallest sample volumes are sufficient. The polarimeters Unipol L series are equipped with plug in connector for the temperature sensor of the SCHMIDT + HAENSCH polarimetric tubes. If polarimeter tubes or quartz control plates with integrated temperature sensor are used the current sample or quartz temperature is indicated at the display. All models of Unipol L series are available as so-called “P version“ for using polarimeter tubes fitted with Peltier elements.
The resolution and precision of Unipol L 1000 and L 2000 polarimeters are higher than the standard model Unipol L. They meets all requirement of quality laboratories. Additional features are:
- Automatic adjustment of beam diameter, necessary for the use of micro tubes
- AWC (Automatic Wavelength Control) – automatic calibration routine
The resolution of all Unipol L models is in complete conformity to the European and American Pharmacopeia. GLP/GMP conform data can be transferred to printer or PC. In addition to 1 parallel and 2 serial interfaces these polarimeters are equipped with PS2 interface for connecting a barcode reader or keyboard.
