BNT-GP60 Automatic polarimeter

BNT-GP series polarimeter is an instrument for measuring the optical rotation of substances. Through the determination of optical rotation, the concentration, content and purity of substances can be analyzed and determined. It is widely used in medicine, petroleum, food, chemical, flavor, fragrance, sugar and other industries and related universities and research institutes.

Product Detail



1: Built-in Peltier temperature control to improve accuracy and stability;

2: There are optical rotation/specific rotation/concentration/sugar degree and custom mode;

3: LED cold light source replaces traditional sodium lamp and halogen tungsten lamp;

4: Complies with 21CFR Part 11 audit trail, complies with Pharmacopoeia 2020 and electronic signature;

5: Comply with GBT14454.5-2008/GBT35887-2018, etc.;

6: Multi-level authority management, authority can be configured freely;

7: 8-inch touch color screen, humanized operation interface;

8: The system comes with an automatic calibration system.


Software function:

Audit trail: full version audit trail and user hierarchical authority management, super administrator can modify
all passwords and user names and traceable, super administrator can modify all operator permissions, user
account has two functions of disable and enable, personnel replacement There is no need to delete the
account temporarily, it can be locked, and it can be unblocked when using it. The U disk exports PDF and Excel
data with tamper-proof function.

A relatively complete audit trail, there should be relevant records for login, logout, data modification, time,
operation steps, export to U disk, etc.


User management: hierarchical management, super administrators assign permissions, administrators can create
multiple users, each user can use their own user name, enter the user name and password when logging in, the
user account has two functions: disable and enable

The highest authority can modify the username and password of others, and can be tracked.


Data retrieval function: convenient for users to quickly find the data they want in a large number of databases


Graph function: real-time display of graphs during the test, which is convenient for analysis


Memory: expandable to 64G


Software upgrade: support U disk automatic upgrade, no need to return to the factory
