Test Your Samples Efficiently
Milliflex filtration units maximize sample preparation efficiency and reliability. The pre-sterilized and ready-to-use Milliflex filter funnel units eliminate time-consuming washing, bagging, autoclaving, and equipment handling. The Milliflex units are disposable. After filtering your sample, you simply break off the funnel from the membrane-containing part of the unit. Sanitizing the Milliflex PLUS vacuum pump is easy, resulting in minimal disruption to your workflow.

Obtain Reliable Test Results
Milliflex filtration units are safe and easy-to-handle devices that eliminate the risk of extraneous contamination that can lead to non-accurate results. We test and certify each lot of product to match your internal requirements. Each Milliflex filtration unit must pass 100% integrity tests and undergo visual uniformity checks.

We offer a complete range of agar-based media in convenient, pre-filled, ready-to-use cassettes. Our high purity ingredients and ISO-certified manufacturing processes give Milliflex media a longer shelf life than formulations prepared on-site. We extensively test each lot of media for pH, sterility assurance, recovery of ATCC strains typically found in bioburden applications, and product formulation. A Certificate of Quality containing all relevant test data is included in every box. Our media conform to the requirements set forth in the pharmacopeias (European, United States, and Japanese).




Milliflex filtration units contain a sealed integral membrane filter that eliminates membrane handling and transfer steps, minimizing the risk of extraneous contamination that can lead to non-accurate results.

Since the membrane is sealed to the plastic funnel in the Milliflex filtration units, there is no possible risk of bypass phenomenon during filtration and the membrane can be completely rinsed prior to the incubation step. The perfectly flat surface of the pre-filled agar media and the convex shape of the membrane after filtration allow perfect contact between agar media and membrane with no trapped air bubbles.
Implement Your Testing Solution with Peace of Mind
Millipore offers a complete range of method development, validation, and maintenance services to help you quickly implement your testing solution and ensure that your system’s performance remains compliant with validated specifications. Millipore experts can help you develop a microbiological test method for your new products that is compliant with current regulations. Our experienced scientists can help reduce the time and cost to validate your bioburden testing methodologies. You can either use Millipore’s validation protocols or have Millipore experts perform on-site validation. For your continued peace of mind, you can select a maintenance agreement for your filtration equipment.
