Pipette Tip Selection Guide
Pipetting users often have a number of considerations when purchasing pipettes, such as precision, feel, brand, and tip fit. However, when selecting a tip, the user's attention is far less than when the pipette is purchased. There is no shortage of flowers to buy imported pipettes, but it is cheaper to buy consumables. In fact, the quality of the tip will have a significant impact on the accuracy of pipetting. So how do you buy a tip? Listen to Yongyue medical for your way~
As the consumable used with the pipette, the tip can be generally divided into: standard tip, filter tip, and low adsorption tip.
· Standard tips are the most widely used tips, and almost all pipetting operations use regular tips, which is the most economical of the tips.
· Filter tips are a consumable designed to avoid cross-contamination and are often used in experiments in molecular biology, cytology, and virology.
· For experiments with high sensitivity requirements, or precious samples or reagents that are liable to remain, low adsorption tips can be chosen to increase recovery. The surface of the low-adsorption tip is subjected to a hydrophobic treatment to reduce the low surface tension of the liquid leaving more residue in the tip.
[As long as the tip that can be fitted is a usable tip" – this is almost universally known to all users for the fit of the tip. This statement can be said to be partial but not completely correct. The tip that can be attached to the pipette does form a pipetting system with the pipette to achieve the pipetting function. But is this reliable? A question mark is required here. Answering this question requires data to speak. You may wish to match the pipette to the tip for performance testing. After the tip is rinsed, several repeated sample loading operations are performed, the amount of each sample is weighed, and the reading is recorded. The accuracy and accuracy of the pipetting operation are calculated after converting the density of the test liquid into a volume. We have to choose a tip with good precision. If the pipette is not properly matched to the tip, the seal between the tip and the pipette is not guaranteed, so the results of each operation are not reproducible. Never use such a tip! Of course, the most efficient way is to buy the original nozzle directly!
