To filter or not to filter... that is the question!
๐Ÿ‘‰ Few people have heard about the advantages of filtering their research peptides. Yes, while it may add an additional step to your routine, it is an important step that provides additional protection for researchers and peace of mind. They are relatively cheap and easy to use. We use them and HIGHLY recommend them!
โ‡๏ธ Benefits of filtering:
Syringe filters offer benefits like quick, convenient, and reliable removal of particles and contaminants from small liquid samples, ensuring sample purity for accurate results, and enabling sterile filtration for media or solutions, all while being cost-effective for general lab use and diverse applications from environmental testing to pharmaceuticals.
  • Protect Analytical Instruments: Prevents particulates from clogging or damaging expensive chromatography columns (HPLC, GC), reducing downtime and extending instrument life.
  • Ensure Sample Purity & Accuracy: Removes impurities, bacteria, and debris, leading to cleaner, more reliable data for analysis.
  • Fast & Efficient: Provides quick filtration for small volumes (under 100 mL) compared to other methods, saving time.
  • Versatile Applications: Used for pre-filtration, clarification, sterilization, and purification in various fields like biotech, pharma, environmental, and food safety.
  • Sterilization: Sterile filters remove microorganisms, making them vital for sterile media, IV solutions, and injectable drugs.
  • Cost-Effective: Inexpensive and disposable, making them practical for everyday lab tasks.
  • Wide Material Options: Available with different membranes (PTFE, PVDF, PES) for compatibility with aqueous, organic solvents, or biological samples.ย 
What you will need:
How to:
  1. Reconstitute peptide and transfer all the contents to syringe.
  2. Remove needle.
  3. Install filter on Luer Lock syringe with the peptide.
  4. Attach needle to filter, no need to screw it on it just goes on top of filter.
  5. Transfer contents of syringe by filtering through to a sterile glass vial. Use as you normally would a peptide vial. NOTE: you should not reuse the original vial to store filtered peptide.
