1. Production Overview
The 50XX-P series is a family of precision piston pumps which provides precise sampling and reagent dispensing. With high aspirating and drainage accuracy, this series pump is a high performance, lost cost and maintenance free precision piston pump and its life time can be more than 5 million cycles without affecting the precision and accuracy. Piston pump has already been widely used in medical and laboratory analytical instruments.
1.1. Characteristics Of 50XX-P Piston Pump
Nominal dispense volume:100ul~5ml, multiple models for option.
Within the life cycle of pump, they have a high stability liquid quantitative precision. When testing medium is deionized water, the CV value as the following table: Percentage of liquid aspiration among total capacity CV (Coefficient of variation)
2%
<1.5%
>10%
<0.5%
A full remove for cylinder:12.7mm
Advanced technology to process zirconia ceramics cylinder, strict inspection program, unique sealing solution, all these guarantee pump's life time above 5 million cycles without maintenance.
Wetted material has a high chemical resistance.
1. Multiple materials for option, ensure chemical compatibility.
2. It has different sealing structure to suit different working conditions.
Optical detection is at the end position. Photoelectric sensor can ensure whether pump is at the primary position.
