Introduction to common fault analysis of pipettes

Pipette common faults:

If not used, adjust the pipette's range to the maximum value to keep the spring in a relaxed state to protect the spring.

It is best to clean the pipette regularly, either with soapy water or 60% isopropanol, then with distilled water, and air dry.

Before autoclaving, make sure the pipette is suitable for high temperatures.

Calibration can be carried out by repeatedly weighing distilled water in a 20-25 degree environment.

Check for leaks during use. The method is to take the liquid and then hang it vertically for a few seconds to see if the liquid level drops. If there is leakage, the reasons are as follows:

1. Whether the gun heads match;

2. Whether the spring piston is normal;

3. If it is a volatile liquid (as is the case with many organic solvents), it may be a problem of saturated vapor pressure. You can suck up the liquid several times before pipetting.

In 2007, Shanghai Bayu ( ) Industrial Co., Ltd. established an offline supply system for laboratory instruments, MRO industrial products, etc. In 2009, it officially launched an online procurement operation platform.

Health Monitor

Health Monitor (Health Care Monitor) is based on the principle of pulse pressure method, and based on the established theory, the model is divided into compartments, and a series of calculation formulas are deduced by linear correlation algorithm. After these formulas are corrected by nonlinear compensation and clinical experience parameters, a set of reflecting cardiac function, vascular condition, blood state and microcirculation function can be obtained.
