What is the Sartorius Minisart SRP 15 Syringe Filter?

This is a lab-grade syringe filter made by Sartorius in Germany. It has a 0.45 micron pore size, which means it catches bacteria, particles, and other unwanted debris from liquids. It's a standard piece of kit used when preparing sterile solutions in a lab or homebrew setting.

Quick Facts

How Does It Work?

You attach the filter to the end of a syringe and push your liquid through it. The 0.45 micron membrane traps bacteria, undissolved particles, and other contaminants. What comes out the other side is a clean, filtered liquid ready for use.

What It's Used For

• Sterilising homebrew oils and solutions before use
• Filtering raw powder solutions during preparation
• General lab filtration where a sterile, particle-free liquid is needed

What to Expect

These filters are reliable and flow well with most oil-based and water-based solutions. The SRP 15 membrane is low-binding, so it won't absorb or strip your solution as it passes through. One filter is typically good for a single batch use.

Possible Side Effects

• Filter may clog if liquid is heavily particulate — pre-filter if needed
• Not suitable for repeated use — single use only
• Incompatible with some aggressive solvents — check chemical compatibility before use

Cycle & Dosage Notes

This is a piece of equipment, not a compound, so there are no cycle or dosage guidelines. Use one filter per preparation session for best results. Always follow proper sterile technique when working with solutions intended for injection.

Storage

Keep at room temperature (15–25°C), away from light and moisture. Leave in the original packaging.
