Item Description
STI501 Isocratic Liquid Chromatograph System is designed by the Research and development team of Surwit Technology Inc.
STI 501 provides the Piston rod automatic cleaning device, the unique technology in the world, which can reduce the piston rod damage, operate costly and be easily operated. Patent design "float type double piston rod and sealing ring" technology can prolong the service life of the sealing ring.
Self-suction check valve to ensure the stability of the pump flow, which is one of the world's most excellent one-way valve. STI 501 owns the smallest pressure fluctuation pump in domestic and foreign (pressure fluctuations are far less than 10 Psi or 0.5 kgf/cm2).
STI 501 Isocratic Liquid Chromatograph System can be easily updated to Gradient Liquid Chromatograph System. In either case, the system incorporates several key features which make it truly one of a kind in the world of HPLC Systems. It can be widely used in the field of medicine, food, chemical industry and environment.
STI PT501 Features
Dual piston series reciprocating pump
Automatic pulse inhibits system
Power-on Self-checker
Automatic check
Automatic to check the pump head type, which easy to detect the inspection parameters settings.
Self-washing Function
Pump head can infusion without manual emptying pipeline.
Solvent compressibility compensation
Improve the precision of the pump by compensating solvent loss caused by different solvent pressure.
Pressure automatic alarm and protect function
Infusion pump can be timely alarmed in accordance with the high and low pressure to protect the pump in advance.
Internal gradient control software
Software can edit and storage of 60 gradient methods, which run and control by itself.
Easy maintenance
All components of pump head are easy to disassemble and wash.
STI UV501 UV-VIS can be connected to any sort of liquid pump, accuracy wavelength, high sensitivity, widely linear rage. This is a cost-effective and reliable, practical, economic testing unit.
Unique pool structure
Efficient optical system and signal processing technology greatly ensure the accuracy and sensitivity of the instrument, repeatability and keep the advantage noise level.
N2000 WorkStation
The detector can be connected to the computer directly through the RS-232 interface for adopting digital signal output. This is very easy to operate for the clients.
Wavelength regulating function:
STI UV501 can be set by the keyboard control panel or program software, it can be choose and
Change wavelength without any mechanical parts.
