High-Precision Dispensing at Low Cost
- A “flow channel extraction” type dispensing system quantifies the amount dispensed by the flow channel volume. Typically, the dispensing volume is determined by the sample loop's length, but this dispensing system uses liquid-level sensors inside the sample loop, to freely adjust the volume.
- In the example image, the liquid pump (P1) delivers the liquid until it reaches sensor 4 (S4), filling the flow channel with liquid. The air is then sent from the pump (P2), and the liquid is dispensed by pneumatic pressure. Dispensing volume can be made in steps by switching the detecting sensors (S1~S5). Buffer can be used instead of air. The quantity and distance of sensors are customizable.
*Note: There may be fluids that may not be detected by liquid-level sensors. Please feel free to contact us with inquiries.
- High precision and repeatability with the fluid path volume determine the liquid volume, which is always constant.
- Different pump options can be selected to meet customer needs. For example, using a high-pressure pump to inject samples or tubing pumps to reduce cost. The example image shows an arm-mounted type, which is compact and lightweight.
