Learn about our technology and solutions in precision microfluid control fields for your unique challenge.
Programmable Syringe Pumps Series, we also call Integrated sampling precision system is a precision sample addition component independently developed by Keyto. Its main function is to realize accurate and quantitative liquid aspiration and dispense and switch between different liquid path channels. The sample addition system integrates a glass tube syringe and a rotary cutting valve, and comes with a control module. It has extremely high aspiration and dispense accuracy and liquid aspiration and dispense accuracy. Users can select and switch the liquid path according to different application scenarios. It is a precision sample addition system with high integration, small size and high flexibility.

Note: Please kindly reach out to our sales team for design and specification final clarification and confirmation.
Various syringes can be used, the accuracy can be from 5ul to 5ml; the length of the screw rod of the stepping motor can be 30mm/60mm.
The number of channel holes of different valves can be customized; the materials of different valve heads and syringes.
The valve head and syringe have extremely high and stable quantitative aspiration and dispense accuracy during the life cycle; replacement and maintenance operations outside the life cycle are also very simple.
