Engineered where standard media fails
Conventional 0.22 µm-filtered media carry mycoplasma-sized particulates (0.2–0.3 µm), subvisible debris, and particulate loads that accumulate inside microchannels — corrupting biosensor readings and shortening device lifetimes. FluxMPS™ addresses these failure modes at the source.
Microchannel-safe purity
0.04 µm final filter stage retains particles down to sub-mycoplasma size; USP <788> Method 1 (light obscuration) particulate compliance verified per batch.
Total metabolic control
User-defined carbon source and precise, lot-controlled nutrient concentrations support metabolic flux and isotope-tracing experiments.
Ultrapure-grade water
Prepared with Ultrapure Type 1 water (18.2 MΩ·cm, ASTM D1193 / ISO 3696) under trace-metal and organic-carbon (TOC) control standards.
Low background for imaging
Low particulate baseline supports confocal microscopy, live-cell biosensors, and TEER measurements without interference from subvisible debris.
Rich, stable nutrient profile
Micro-batch precision manufacturing locks in amino acid and vitamin concentrations, ensuring lot-to-lot reproducibility critical for long-term perfusion studies.
Customization on demand
pH, glucose concentration, salts, HEPES, and full nutrient composition available on request. Contact support@diagnocine.com.
Quadruple-stage filtration system
FluxMPS™ Basal Medium Eagle (BME), 25mM HEPES: 1X Liquid is a ready-to-use formulation processed through a four-stage serial filtration sequence that reaches 0.04 µm — addressing mycoplasma-sized particulates, subvisible debris, and bioburden that 0.22 µm filtration alone cannot address.
-
1
0.1 µm Prefiltration I
Removes large particulates, cell debris and protein aggregates; protects the first 0.04 µm final-filter cartridge.
-
2
0.04 µm Final filtration I
First 0.04 µm pass; retains sub-micron particulates and microaggregates that pass a 0.22 µm filter, including mycoplasma-sized (0.2–0.3 µm) organisms.
-
3
0.1 µm Prefiltration II
Second dedicated prefilter, protecting the second 0.04 µm final-filter cartridge from residual particulate load.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill & finish performed in a validated laminar-flow (ISO Class 5 / Class 100) workstation.
Performance vs. conventional media
By reaching a 0.04 µm final pore size across four sequential stages, FluxMPS™ delivers approximately 5× cleaner media by particulate count compared to single-pass 0.22 µm filtration, with USP <788> Method 1 compliance verified on every production batch.
