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
