Transfer Pipette Purchase Method

In the study of the analysis of the test, the general use of pipettes to take a small amount or a small amount of liquid. For the proper use of pipettes and some of its details, many people will be ignored.

How to buy

1. Product performance, that is, the accuracy and repeatability of the pipette for the vast majority of users, the performance of the product before the purchase of both difficult and unnecessary. Therefore, mainly based on the technical data provided by the manufacturer. But here is to explain two points: First, do not easily believe that the seller's verbal commitment, we must consult the manufacturer to provide written materials; Second, in the global pipette market impact on the larger brand, its technology Data is more reliable.

2. The reliability of the product is dependent on the material used in the pipette. For the shell, there should be a high impact resistance, corrosion resistance and low thermal conductivity (such as PVDF material); for the piston, the current market mainly stainless steel, ceramic and plastic three materials. Stainless steel mechanical properties, long life, but not suitable for strong acid and alkali of the pipetting; ceramic is a high corrosion resistance, but poor mechanical properties. Of course, high-quality materials often mean higher prices, so the need to consider the purchase price and life factors.

3. Ergonomic design of the product can be considered the following points:

First, to complete a pipetting cycle thumb short moving distance, which means higher comfort;

Second, compare the same range of pipettes to complete a discharge (must press in the end) required thumb force, which is the key to the impact of comfort, the less the means that long-term use of the risk of injury caused by the smaller finger;

Third, loading and unloading suction head, the same is the more effort the better;

Fourth, the weight of the pipette is moderate, too heavy will increase the burden of the hand, but too often also means that the material may be unsatisfactory;

Fifth, other ancillary design, such as the frosted design of the shell and finger hook design, help to further improve comfort. SOCOREX in ergonomics, in the global pipette market are in a leading position in the above points have a perfect performance.
