In long-term liquid delivery experiments conducted at set ow rates from 1 mL/min to 40 mL/min, excluding the initial 1 hour until the tube stabilized, it was conrmed that very stable ow control is possible with a CV value of 1.07%. Additionally, upon evaluating the effects of liquid temperature, it was demonstrated that stable liquid delivery can be achieved under consistent temperatures. These results indicate that the peristaQuantumPump can achieve high precision and stable liquid delivery across a broad range of ow rates.Correlation between pump rotation speed and ow rateFlow stability Eect of liquid temp.Setting 1 mL/min 10 mL/min 20 mL/min 30 mL/min 40 mL/minConditionMeasurement time：１～ 24 hours　　　　Interval：5 minutesLure-attached Olen tube　4/6Average 1.0 mL/min 9.9 mL/min 20.0 mL/min 30.0 mL/min 40.2 mL/minSD 0.007 0.106 0.206 0.220 0.241CV(%) 0.75% 1.07% 1.03% 0.73% 0.60%2

CalibrationPeristaltQuantumPump, likes other tube-based pumps, utilize the elasticity of the tube to transport uids. The core mechanism of this pump involves the continuous compression of the tube by rollers moving along it. This action, combined with the pressure exerted and the tube’s restorative force, propels the uid. PeristaltQuantumPump employs self-propelled rollers. When the main shaft (A) rotates, the surrounding rollers (B) move in the direction of the shaft’s rotation. Upon contacting the tube, rollers (B) rotate in the opposite direction of the main shaft (A) while compressing the tube. As the tube passes through the compression section, a negative pressure is created inside, drawing in liquid, and the rotational motion expels the liquid on the outlet side. Since the liquid only travels inside the tube and does not come into contact with other parts of the pump, the risk of contamination is extremely low. Additionally, simply replacing the tube allows for easy cleaning and maintenance. The elasticity of the tube also enables the transport of viscous liquids or liquids containing particles.PeristaltQuantumPump offers precise ow control and high reproducibility, making them suitable for a wide range of applications in the medical, research, and industrial elds.DirectionABBBBBBInnovative technologyFluid control with PeristaQuantumPumpSimple calibration with semi-automatic operationDirection10080604026 mL100908070605040302010100mlFlow rateSetting tubeSetting timeWhen you tap the input space for ow rate (%) and liquid delivery time, a numeric keypad will be displayed, so enter the desired values.

It is highly resistant to organic solvents, strong acids, or strong alkaline chemicals and is made from materials with superior durability to physical forces.Chemical resistanceStandards and performance of Olen tube with lureDifference between ChannelsChannel１Channel２1 channel liquid transfer: Liquid transfer using either channel 2-channel liquid transfer: Liquid transfer using both channels *Evaluate each ow path individuallyThe table below shows a comparative evaluation when replacing the pump head of a peristaltic quantum pump, and the results of a comparative evaluation of ow rates using 10 olen tubes with lures of the same standard. Even if the olen tube with luer was replaced or the pump head was replaced, the same ow rate was shown. Both the pump head and the olen tube with luer are strictly standardized and quality controlled, so even after replacement, the ow rate can be controlled with the same accuracy.Difference between Pump head and Olefin tube with luerPump head Olen tube with luerThe table below presents the resulats of a comparative evaluation of ow rates using either one (1 channel) or both (2 channels) of a two-channel PeristaQuantumPump (WSP-3310-2) equipped Olen tubes with lures. The ndings indicate that the ow rate remains consistent irrespective of the channel used. Additionally, there is no variance in the flow rate delivered to each channel, whether one or two channels are operated simultaneously.4

With 12 rollers minimizing the effects of pulsation, it achieves reproducible liquid delivery with high ow rate precision. Proper compression control extends the tube’s lifespan to over two weeks, even with continuous operation at maximum ow rate, while maintaining ow rate precision and stability. Utilizing three ow paths, it allows for the delivery of multiple targets under identical conditions with even ow rates or the delivery of multiple solutions at the same ow rate. Moreover, with the PQP support program, external control can be easily programmed.
