High-Precision Dispensing at Low Cost A "flow channel extraction" type dispensing system quantifies the amount dispensed by the flow channel volume. Typically, the determined dispensing volume is 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. Therefore, the air is sent from the pump (P2), and the liquid is dispensed by pneumatic pressure. The dispensing volume can be changed into steps by switching the detecting sensors (S1~S5). Using a buffer instead of air is possible. The quantity and distance of sensors are customizable. Note: There may be fluids that liquid-level sensors may not detect. Please feel free to contact us with inquiries. High precision and repeatability with the fluid path volume determine the liquid volume, always constant. The selection of different pump options is possible to meet customer needs. For example, using a high-pressure pump to inject samples or tubing pumps reduces cost. The example image shows an arm-mounted type, which is compact and lightweight. Note: Details such as specifications, etc., may be changed without notice.
