The pump can accept different sizes of glass syringes from 25µL to 25mL, enabling syringe replacement. For the syringe replacement procedure and more details, please refer to the follow steps or contact our product specialist for assistance.
Figure 1 ASP-SY0360 Industrial Syringe Pump Configuration
Step 1: Empty the syringe and flow path, and disconnect all fittings and tubing.
Step 2: Unscrew the Thumb Screw using the M4 Allen wrench provided in the original package.
Step 3: Send the following ASCII commands to the pump to initialize the pump and valve: /1ZR, /1I1A6000R (Move the Plunger Seat to the maximum stroke to the bottom of the pump)
Step 4: Unscrew the original glass syringe clockwise in the vertical direction, ensuring no damage to the syringe threads on the switching valve port.
Step 5: Pull the plunger in the new glass syringe to its maximum stroke and align the plunger end with the Plunger Seat by aligning the hole. Ensure the plunger is vertically aligned when threaded counterclockwise into the female ¼”-28 hole on the switching valve.
Step 6: Reinitialize and move the Plunger Seat to the home position.
Step 7: Manually move the syringe plunger to the bottom of the syringe and align the hole with the Plunger Seat. Use the Thumb screw to tighten the Plunger Seat and the Plunger of the glass syringe.
Step 8: After installation, reconnect the tubing to the female threaded ports on the switching valve.
Step 9: Run the following ASCII codes: /1ZR, /1I1A6000R, /1A0R (to aspirate 6000 full steps to Port 1 and dispense all liquid back to the beaker). Check for any leakage during aspirate and dispense.
Step 10: If leakage is observed, inspect the flow path and tighten the fittings to avoid further leakage.

Syringe Pump Flow Rate Calculation
This digital syringe pump (dLSP500) is designed for precision fluid handling laboratory applications. It accepts syringe size from 0.5uL to 60mL. Let's consider the dLSP500 syringe pump to estimate the flow rate range. This pump has a linear translation speed range of 0.0833mm/min to 180mm/min, with a resolution of 0.03255µm/µstep. Table 1, 2, and 3 list commonly used syringe sizes and their inner diameters. The inner diameter of a 5 mL BD plastic syringe is approximately 11.98 mm. Using this information, we can calculate that the flow rate of the syringe pump ranges from 9.389 µL/min to 20.289 mL/min. The flow rates for other syringe sizes can be calculated in a similar manner. In addition, the average pressures for any syringe pump and syringe together can be estimated by dividing the average force applied on the syringe pump and the syringe surface area.
Syringe Pump Selection Guide
A syringe pump is a device that is used to accurately and precisely dispense small amounts of fluid over a period of time. It typically consists of a control unit that is connected to a motorized pump and a syringe. Syringe pumps work by using a motor to drive a plunger that pushes fluid out of a syringe. The control unit of the pump can be programmed to dispense a specific volume of fluid at a specific flow rate over a specified period of time. The motor moves the plunger at a consistent speed, ensuring that the desired volume of fluid is dispensed at the desired rate. Some syringe pumps also have the ability to reverse the direction of the plunger, allowing them to draw fluid back into the syringe. This feature can be useful for tasks such as flushing a line or emptying a syringe. Syringe pumps are highly accurate and precise, making them an essential tool in a variety of applications.

Practical Fluidic Interface Guide for Electric Rotary Valves in Laboratory Automation
The electric rotary or multi-channel switching valve is a stepper motor-driven fluid handling valve designed for automated fluidics applications. This precise rotary valve automates the routing of fluidic volumes, allowing for the handling of aggressive fluids and switching flow directions as needed. For instance, in a multi-channel distribution valve, a common central port connects the stator and rotator, enabling the switching of flow direction between different ports with a rapid response time of less than 120ms for adjacent ports. This switching valve can communicate through RS-232, RS-485, or CAN interfaces, allowing for multi-valve arrangements of up to 15 valves in one group. See Figure 1 for the wiring instruction. It supports group control and individual addressing, making it versatile for various automation needs. The wetted materials in the flow path are PCTFE/Sapphire and can be customized upon request.
Industrial Syringe Pump Basics: Accuracy/Precision, Resolution and Flow Rate Calculation
The resolution of industrial syringe pumps refers to the smallest increment of movement or volume that the pump can achieve. It is typically specified by the manufacturer and is important for applications requiring precise control over fluid delivery. To calculate the resolution of a syringe pump, you need to know the steps per revolution of the motor (if it's a stepper motor-driven pump) or the linear resolution of the pump mechanism. The linear resolution is usually given in units of distance per step (e.g., mm/step or µm/step). In this article, the basics of typical industrial syringe pumps, namely, the accuracy and precision, resolution and flow rate calculation (stepper motor driven), are briefly reviewed.
