Both standard and low-retention pipette tips are used in laboratory settings to dispense liquids; however, their ability to lower liquid retention varies.
The common, affordable, and durable plastic used to make standard pipette tips is polypropylene. However, because of its slight hydrophobicity, polypropylene can draw in and hold onto certain liquids, especially those that are sticky or viscous. This liquid retention could affect pipetting accuracy, especially when working with small volumes.
Reducing liquid retention is the aim of low-retention pipette tips. They are typically made of a particular kind of polypropylene and have a silicone lubricant covering them. The surface of the tip is now more hydrophilic as a result of these modifications; liquids are repelled from the tip and are prevented from sticking to its interior. This results in more accurate and dependable pipetting, especially when working with pricey or sensitive reagents.
When handling tiny amounts or delicate chemicals, for example, low-retention pipette tips are typically recommended. Standard pipette tips work well for routine laboratory use when liquid retention is not a major concern. For more information, please click:https://www.cqscopelab.com/pipette-tips
