What Do We Need to Consider when Choosing a Laboratory Syringe Pump?

Laboratory syringe pumps are widely used in biological and chemical reaction injection experiments, long time animal drug injection experiments, electrostatic spinning, microfluidic field applications and other laboratory microinjection experiments, etc. Through mechanical devices to push the syringe, it can achieve high precision and smooth liquid transfer.

I. Working Principle of Laboratory Syringe Pump

The laboratory syringe pump is generally used for micro or "short time" fluid feeding. According to the number of channels and structure, they are common: single channel, double channel, multi-channel, bi-directional continuous, split syringe pump, etc. The general user can choose the syringe pump according to the use environment (such as whether there is a magnetic field or high pressure) and experimental needs.

When the laboratory syringe pump works, the microcontroller system sends out control pulses to make the stepper motor rotate, and the stepper motor drives the screw to turn the rotational motion into linear motion to push the piston of the syringe for injection and infusion to achieve high precision, smooth and pulsation-free liquid transfer. The injection speed can be set by the operator through keyboard operation.

II. What Aspects Need to be Considered When Choosing a Laboratory Syringe Pump?

As a professional syringe pump supplier, we provide different types of syringe pumps. When choosing a syringe pump, you can consider the following factors.

1. Laboratory syringe pump specifications and material requirements. There is a wide variety of syringe types, such as plastic, glass, stainless steel, etc. Syringe interface screw and conventional syringes with needles. Different syringe specifications for different syringe pumps are not the same, and different syringe specifications correspond to different flow rates.

2. Laboratory syringe pump function and appearance selection. Different brands and models of syringe pumps also differ in function. Such as chemical reaction injection experiments, electrostatic spinning, prolonged animal drug injection experiments and other laboratory microinjection. Conventional syringe pumps only have the function of propulsion, that is, only the injection of liquid, part of the experimental scenario requires the extraction of fluid. Syringe pumps are also divided into horizontal syringe pumps and vertical syringe pumps.

3.Laboratory syringe pump channel selection. According to the use of scenarios and other current and subsequent experimental requirements to choose a reasonable number of channels of the pump. Channel can be divided into independent and separate control of the syringe pump, a common push block of the pump. Shared push block syringe pump flow rate generally can not be adjusted and the need for different syringe flow rate scenarios will be less practical. Some users may need the syringe pump to achieve continuous feeding, continuous syringe pump can be considered. But continuous syringe pump switching will have a break in the flow, not seamless or real-time switching.

4. The price of laboratory syringe pumps. Different brands, configurations and parameters mean a wide range of prices. According to our own budget, we can choose the product with a proprt price and to make sure the function of it meet the needs of the syringe pump.
