K2025High Performance Liquid Chromatography
With the reliable design and high-quality components, K2025 passes the reliability test performed by authority, ensuring the long-term running in optimum condition.
The precision and accuracy of the results are guaranteed with our unique pumping and sampling technology, high sensitivity detector, and powerful data processing software.
Ease of use
The operation is more convenient and efficient with a variety of user-friendly designs in Wookinglab
Wookinglab fully complies with FDA 21 CFR Part 11 with database mode and data traceability.
K2025 P1/P2/P4 Pump
The precise gradient change and retention time are guaranteed with the reciprocating tandem plunger pump and pressure dynamic suppression algorithm. The repeatability of retention time is less than 0.2%.
The reliable design makes service life longer
The cam is integrally processed from high-hardness alloy steel and combined with high-frequency heat treatment technology, which makes the surface of the cam is more wear-resistant (the hardness is above 55HRC), and the service life is longer.
The high-power customized motor, Japanese NSK bearings, and independent air duct make the power and life even better.
Self-lubricating and wear-resistant materials imported from Germany are used for the piston drive mechanism. Also, the inner wall rifling design prevents the piston from accidentally locking, making the gearing more reliable.
The patented suspended floating plunger(Patent Number: ZL 2020 2 1896102.3 ) can adapt to the working conditions automatically, which is convenient for disassembly and prevents the eccentric wear of the sealing ring effectively. With the special sealing structure and the automatic cleaning of the plunger, the pump seal is more reliable.
Ease of use
Equipped with an online automatic rinsing mechanism
When the pump is working, the rinsing pump is automatically turned on and runs periodically, which can effectively prevent the crystallization of buffer salts and the growth of microorganisms, and prolong the service life of the plunger and plunger sealing.
Intelligent solvent replacement and evacuation to improve work efficiency
Equipped with a 4-channel solvent selection valve, according to the method and sequence used in the mobile phase, to achieve automatic switching.
Independent 4-channel gradient proportioning valve, easy for maintenance
The gradient proportioning valve of the quaternary pump adopts a 4-channel independent design. The intelligent monitoring and diagnosis can realize real-time monitoring and independent replacement of each channel, the whole design can reduce maintenance costs effectively.
Precise injection volume
The K2025AS autosampler adopts unique all-in-one constant pressure sampling needle (Patent Number: ZL 2020 2 1159205.1) and ultra-precision injection pump to ensure accurate injection volume and excellent injection linearity, thus making the quantitative results more accurate.
Low carryover to make results more accurate
The sampling needle is highly polished for the outer surface and passivated for the inner surface, which can effectively reduce the sample residue. The carryover is much lower when needle washing of the outer and inner surfaces are performed.
Ease of use
Patented preloaded sample injection mode(Patent Number: ZL 2020 2 2977790.2), the injection time can be shortened to 5s, which greatly improves the efficiency.
A variety of injection modes combined with sample temperature control technology to satisfy different detection needs such as rare and unstable samples
The dehumidification function is optionally equipped to avoid the generation of condensed water, effectively prevent the sample from being diluted, and ensure accurate results
The maintenance is more convenient and efficient with the in-front injection valve.
Precise temperature control ensures good separation and repeatability
Using fuzzy PID intelligent temperature control algorithm, ban-based air circulation, and multiple insulation layer design, the column temperature is more accurate, stable, and uniform, the temperature stability is±0.1℃, and the temperature for each analysis are constant and consistent.
Triple protection, more safe to use
Real-time liquid leak protection, intelligent monitoring of Peltier and cavity temperature, over-temperature power-off protection, triple safety protection designs, effectively prevents accidental liquid leakage and dangers caused by over-heating.
The patented transmission type deuterium lamp and static light path (Patent Number: ZL 2020 2 0832429.8) allow the light source switching without moving of lamp, which is more reliable.
With the patented design of the optical unit (Patent Number: ZL 2020 2 0832429.8) and the light source module, the service life is much longer.
Maintenance and safety
Diode Array DetectorSpecifications:
Spectral similarity alignment and peak purity determination are performed for precise qualitative and quantitative analysis
