Pipette Tips and filter tips
  1. Filter Tips:

Filter tips feature built-in filters, usually made of hydrophobic material such as polyethylene (PE), polypropylene (PP), or porous materials like porous polytetrafluoroethylene (PTFE). These filters prevent aerosols, contaminants, and liquids from entering the pipette shaft, reducing the risk of sample cross-contamination and pipette contamination. Filter tips are ideal for applications involving sensitive samples, such as PCR, RNA/DNA isolation, and cell culture.

  1. Low-Retention Tips:

Low-retention tips are designed to minimize liquid adhesion to the inner surface of the tip, thereby reducing sample loss and ensuring maximum sample recovery. These tips are particularly useful when working with viscous or low-volume samples, where sample retention can lead to inaccurate volume measurements. Low-retention tips are commonly used in molecular biology, genomics, and proteomics applications.

  1. Extended Length Tips:

Extended length tips feature a longer tip shaft compared to standard tips, allowing for easier access to deep or narrow containers, such as tubes and microplates. They are often used in applications where precise dispensing into small vessels or wells is required, such as high-throughput screening, microarray spotting, and liquid handling automation.

  1. Specialty Tips:

Specialty disposable pipette tips are designed for specific laboratory applications or unique sample types. Examples include tips with conductive properties for electrostatically sensitive samples, tips with ultrafine points for precise dispensing, and tips with beveled or tapered ends for cell manipulation and microinjection techniques.

  1. Low-Retention Filter Tips:

Combining the features of low-retention and filter tips, low-retention filter tips offer enhanced sample protection and minimal sample loss. They are ideal for applications requiring both reduced sample adhesion and contamination prevention, such as PCR, qPCR, and Next-Generation Sequencing (NGS).

These are just a few examples of the types of disposable pipette tips available in the market. When selecting the appropriate type of pipette tip for your laboratory needs, consider factors such as sample type, application requirements, and compatibility with your pipettes.

How to Use Disposable Pipette Tips?

Mastering the proper use of disposable pipette tips is essential for obtaining accurate and reproducible results in the laboratory. Follow these guidelines for optimal performance:

Best Practices for Using Disposable Pipette Tips

Using disposable pipette tips correctly is crucial for obtaining accurate and reproducible results in laboratory experiments. Here are some best practices for using disposable pipette tips:

  1. Selecting the Right Tip: Ensure that the pipette tip you choose is compatible with your pipette model and suitable for the volume you intend to pipette. Using the correct tip size and type minimizes the risk of inaccuracies and ensures optimal performance.
  2. Proper Tip Attachment: Before pipetting, ensure that the pipette tip is securely attached to the pipette shaft. Press the tip firmly onto the pipette until it clicks into place to prevent leaks and ensure a tight seal.
  3. Priming the Pipette: Prime the pipette tip by aspirating and dispensing the liquid once or twice before transferring samples. This helps ensure that the pipette tip is filled with the liquid and eliminates any air bubbles, resulting in accurate volume delivery.
  4. Avoiding Over-Pipetting: Do not pipette liquid beyond the tip’s maximum volume capacity. Over-pipetting can lead to liquid getting into the pipette shaft, contaminating the pipette and affecting subsequent measurements. Always check the volume markings on the pipette and adjust accordingly.
  5. Maintaining Proper Technique: Maintain a steady hand and consistent pipetting technique throughout the procedure. Hold the pipette vertically when aspirating and dispensing to ensure accurate volume measurement and minimize liquid splashing or dripping.
  6. Preventing Tip Touch Contamination: Avoid touching the pipette tip to any surface, including the inside of the container or the walls of the receiving vessel, as this can lead to contamination. Instead, hold the pipette tip slightly above the liquid surface to aspirate and dispense samples.
  7. Changing Tips Between Samples: Change pipette tips between samples to prevent cross-contamination. Discard used tips promptly into a designated waste container and use a new, sterile tip for each sample or reagent transfer.
  8. Avoiding Aerosol Formation: To minimize the risk of aerosol formation, especially when pipetting volatile or hazardous liquids, pipette slowly and gently. Additionally, use filter tips or low-retention tips to prevent liquid aerosols from entering the pipette shaft.
  9. Storage and Handling: Store disposable pipette tips in their original packaging or in a clean, dry environment to prevent contamination. Handle tips carefully to avoid damage or deformation, which can affect their performance and accuracy.
  10. Regular Maintenance and Calibration: Regularly inspect the pipette and tips for any signs of damage or wear. Calibrate the pipette according to manufacturer guidelines to ensure accurate volume measurement.

By following these best practices for using disposable pipette tips, laboratory personnel can minimize errors, ensure sample integrity, and achieve reliable and reproducible results in their experiments.
