A Complete Guide to Micropipette Tips: Choosing the Right One for Your Lab

Selecting the correct micropipette tips is vital for accuracy, reproducibility, and protecting your valuable samples. In this guide, we’ll walk through the key considerations in choosing tips for your laboratory, including when to go for micropipette filter tips, and introduce a trusted source for high-quality tips.

Why Tip Choice Matters

Micropipettes are only as good as the tips you pair with them. A mismatched or low-quality tip can introduce errors, cause leakage, or lead to contamination. For critical assays—especially molecular biology work—choosing the right tip is essential.

Key Factors in Choosing Micropipette Tips

  1. Compatibility & Fit
    Ensure the tip matches your pipette’s geometry and volume range. Tips that are too loose or too tight can cause inaccuracies.

  2. Material & Purity
    Look for tips made from high-quality, low-binding plastics. Certified “sterile,” “DNase-/RNase-free” or “ultra-clean” options help avoid introducing unwanted nucleic acids or RNases.

  3. Tip Type & Specialty Features

    • Standard / universal tips: suitable for general pipetting tasks.

    • Micropipette filter tips: have built-in barriers that block aerosols and prevent cross-contamination. These are especially beneficial in PCR, qPCR, pathogen handling, or diagnostic assays.

    • Low-retention / hydrophobic-coated tips: useful for viscous or sticky samples to minimize sample loss.

  4. Volume Range & Precision
    Choose tips that cover the full volume range you use frequently. For small volumes (e.g. < 10 µL), precise tips are more critical.

  5. Packaging & Sterility
    Filtered tip boxes, racks, or individually wrapped tips offer differing levels of protection and convenience. Sterile packaging reduces exposure to contaminants.



Best Practices in the Lab

  • Use a fresh tip with each sample to avoid carryover.

  • Pre-wet tips (aspirate/dispense once) to minimize pipetting error.

  • Insert the tip just a few millimeters into the liquid, and hold the pipette vertically.

  • Discard tips carefully and keep tip racks covered to prevent dust or airborne contamination.

  • Always choose micropipette filter tips when contamination risk is high or sample integrity is critical.

For a wide selection of premium, reliable micropipette tips and micropipette filter tips, explore the catalog at Microlit. Their offerings cater to various pipette models and lab requirements, ensuring you get the performance you need.

Selecting the right tip—and using it correctly—can significantly enhance your experimental consistency and protection against contamination.
