Feature Comparision

Compared with Traditional Peristaltic Pump

WSP Peristaltic Pump
Traditional Peristaltic Pump
Filling Accuracy
high accuracy,high repeatability, filling 10μl error<±0.1μl, 100μl error<±0.5μl
don’t suitable for filling less than 100 ul,200μl error<±3μl
Filling Efficiency
high efficiency, productivity up to 120 bottles/min
average efficiency, productivity<40 bottles/min
Attenuation
12 hours continuous operation, attenuatio<1%, work one day without calibration
12 hours continuous operation,attentuation>5%, need to calibrate every 2 hours
Tube Life
continuous operation, service life>1000 hours
fail after 70-100 hours of continuous operation
Pulsation
no pulse, small impact, no splash
large pulse, easy to splash

Compared with Plunger 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
