1、 The industry's urgent need for long-term repetitive liquid separation

In precision experimental scenarios such as drug development, food microbiological testing, and immunoassay, the repeatability of liquid separation operations directly determines the reliability of data. Especially when faced with batch sample processing or long-term liquid separation tasks lasting more than 12 hours, traditional instruments often encounter problems such as accuracy drift and decreased channel consistency - for example, the human error of manual pipettes can reach ± 2% or more, and the coefficient of variation (CV) of ordinary automatic liquid separators significantly increases after continuous operation, seriously affecting the traceability of experimental results. Therefore, it has stable long-term repeatabilityLiquid analyzerInstruments have become the core support for the efficient operation of laboratories. ​

2、 The core influencing factors and technological breakthroughs of repeatability in liquid separation

Key technical bottlenecks

Mechanical structural stability: During long-term operation, pipeline wear and aging of seals can lead to leakage or flow fluctuations; ​

Calibration system accuracy: Accumulated errors between channels and changes in environmental temperature and humidity can disrupt the consistency of liquid separation. ​
