Model L.TEX8522 Syringe Pump 
The distinct advantage of the syringe pump is that the pump is able to deliver mobile phase at low flow rate with very low pulsation. The model 8522 Syringe Pump can be used for the measurement to require precise flow rate, low pulsation and delivery of high viscosity solvents.


Model L.TEX8523 Syringe Pump 
The model 8523 has been developed for the application in the low flow rate range, so it covers the flow rate range from 0.5 ~ 500μl/min. In order to increase resolution, the long narrow cylinder is designed. Motor drive high pressure valves are employed to aspirate and discharge the solvent automatically. When all solvent in the cylinder is discharged, the valve is automatically switched to aspirate the solvent.

Model L.TEX 8500 Nano Flow Pump 
Recent development of analytical technologies for bio technologies field demands larger and more accurate information from very minute sample amounts. For those applications, the mass spectrometers have been used as detectors. The pump which introduces the samples to the mass spectrometer requires very accurate delivery of minute samples. Therefore, the syringe pumps have been widely used. However, there was a problem that commercial available pumps had been very costly and large. L.Tex has developed the model 8500 with a compact body and attractive price including all necessary functions. The operation is easy even for a novice to learn. And the model 8500 can be operated through the key pads as a stand-alone model as well as through the PC.
