What is the difference between pipette tips and filter tips?

Pipette tips” and “filter tips” are terms often used interchangeably, but they can have different meanings depending on the context. Here are the distinctions between the two:

  1. Pipette Tips:
    • Definition: “Pipette tips” is a broad term referring to the small, disposable attachments used with pipettes for measuring and transferring liquids in laboratories.
    • Varieties: Pipette tips come in various types, including regular tips for general use, extended-length tips for accessing deep or narrow containers, low-retention tips to minimize sample loss, and sterile tips for maintaining aseptic conditions.
    • Common Use: Pipette tips are the general category of disposable tips used with pipettes. They may or may not have additional features like filters.
  2. Filter Tips:
    • Definition: “Filter tips” specifically refer to pipette tips that include a built-in filter at the top or within the tip.
    • Function: The filter in a filter tip serves to prevent aerosols and liquids from entering the pipette during aspiration, acting as a barrier to protect the pipette and maintain sample integrity.
    • Applications: Filter tips are commonly used in applications where preventing contamination of sensitive samples is crucial, such as in PCR (polymerase chain reaction) and other molecular biology techniques.

In summary, all filter tips are a type of pipette tip, but not all pipette tips are filter tips. Pipette tips, in a general sense, can refer to a variety of disposable tips used with pipettes, while filter tips specifically have a built-in filter to provide additional protection against contamination in certain applications. When selecting pipette tips, it’s important to consider the specific requirements of the experiment or procedure and choose the appropriate type of tip, whether it includes a filter or not.
