The difference between several common tips

Standard tips have a good fit and leak-proof seal for ideal pipetting accuracy and repeatability

Filter tips have more space between the sample and the filter than traditional filter tips. Greatly eliminates the risk of expensive or infectious samples coming into contact with the filter

The low adsorption filter cartridge is used for experiments with relatively high sensitivity, or precious reagents and samples that are easy to remain, which can reduce the loss

The extended filter tip prevents liquid back suction and avoids cross-contamination in experiments, molecular biology, cytology, virology
