Characteristics Comparison

Microliter Peristaltic Pump Traditional Peristaltic Pump
Filling accuracy When filling 10 μ L ,error less than ± 0.15 μ L. When filling 100 μ L, error less than 1 μ L. Accuracy error less than ± 0.3% not suitable for filling less than 100μL, the error of 200μL is less than ±3μL
Filling efficiency Can reach 120 bottles/minute. the output is less than 40 bottles per minute.
Volume decrease Run continuously for 12 hours with less than 1% attenuation, and no calibration is required for a day’s work. The continuous running time is 12 hours, and the attenuation is more than 5%; usually it needs to be calibrated every 2 hours.
Tube life More than 1000 hours when it runs continuously. Between 70 to 100 hours.
Characteristics Perfect combination of special mechanical structure and tube kits realizes zero hanging liquid. Traditional structure,it’s easy to hang liquid at the tip of the needle

 

Compared with Plunger Pump

WSP3000 Peristaltic Pump Plunger Pump
Cleanliness no dead volume,no effusion,material only contact with clean pipeline,no pollution dead volume, effusion,material contact with the pump head cavity, clean not thoroughly
Ease of Use filling different material,only replace the pipeline to avoid cross contamination, low cost,simple maintenance One pump can only fill one material, complicated maintenance
Universality the material may contain particles such as magnetic beads material must be clean and free of impurities
Filling range 1μl~3000μl replace the pump tube adjustable range＜5 times
Dripping retractable without dripping easy to drip
Cavity Shedding low extrusion strength,no mechanical friction,smooth cavity wall without shedding continuous mechanical friction,the cavity is easy to fall off particles

 

Microliter Peristaltic Pum Ceramic Plunger Pump
Cleanliness No blind area, no accumulation of liquid, materials only contact with clean tube, no pollution. Blind area, liquid accumulation, contact between material and pump head cavity, and insufficient cleaning.
Usability Filling different materials requires only replacement of tubes to avoid cross contamination, simple maintenance, and low cost A pump can only fill one material, and the maintenance is complex.
Universal The liquid may contain magnetic beads and other particles. The liquid must be clean and free of impurities.
Filling range 1μL~3000μL(single channel) 0.3~100mL,0.5~500mL(single channel)
Liquid drop No dropping Easily Dropping
Fallen objects Low extrusion strength, no mechanical friction, and smooth inner wall of the cavity without shedding objects Mechanical continuous friction, easy detachment of particles from the cavity

1.Test condition for the above data:
At normal temperature and pressure, with the level of water unchanged, silicone hose is used for transmission. The inlet end is 1 meter and the outlet end is 1 meter. All weighing data are measured by Sartorius high-precision balance with accuracy of one hundred thousandth.
2.The error value and accuracy data are based on 50 sets of continuous measurements, and this data does not include the
influence of the last drop.
3.12-hour decay rate：
Under the condition of 60 bottles/minute, after the equipment is installed and debugged, run for 3 hours first, then record 10 sets of filling data every 12 hours, run continuously for 5 days and take the maximum value.
4.During the filling process, the precipitation of dissolved gases in the liquid will produce bubbles, which will have a great impact on the accuracy of filling below 1000μl. Pay attention to bubble removal during use.
