Semi-automatic Protein Content Analyzer for Pharmaceutical Excipients with 0.1

Product Specification

ST207BS Semi-automatic protein content analyzer for pharmaceutical excipients

The ST207BS semi-automatic protein content analyzer for pharmaceutical excipients complies with the 2020 Chinese Pharmacopoeia 0704 Nitrogen Determination Method Third Method Nitrogen Meter Method and 0731 Protein Content Determination Method First Method Kjeldahl Nitrogen Determination Method. Suitable for the determination of nitrogen content in nitrogen-containing compounds using constant and semi trace methods, mainly used to detect protein nitrogen content in pharmaceutical excipients, chemicals, grains, dairy products, etc. The process is controlled by a microcomputer, with rich display information, making it easy for users to hold the instrument and complete the distillation of samples in a few minutes. It can be operated in manual and automatic modes, making it convenient for customers to choose.

Performance Characteristics

● Switching between manual and automatic modes, automatic quantitative addition of alkali solution and boric acid absorption solution.

● Automatic mode: One click completion of automatic water addition, automatic water level control, automatic dilution, automatic acid addition, automatic alkali addition, and automatic distillation. Customers can set different automatic working times according to their sample needs. In automatic operation mode, the pause function can be used to increase the usage of each reagent in manual operation mode.

● Manual mode: Customers can choose manual mode for separate operation of four processes: dilution, acid addition, alkali addition, and distillation. Time and dosage can be controlled by oneself.

● Can store 10 sets of experimental programs to meet different user needs.

● The distillation time can be set arbitrarily, and an automatic alarm will be triggered when the distillation ends

● A perfect safety protection system that can measure and protect against overheating and overpressure in distillers and pipelines

● Intelligent design of automatic fault detection and sound light alarm system

● The widespread use of corrosion-resistant materials such as stainless steel can extend the service life of instruments
