FluxMPS™ Minimum Essential Medium (MEM), Low Glucose w/o Phenol Red: 1X Liquid
FluxMPS™ Minimum Essential Medium (MEM), Low Glucose w/o Phenol Red: 1X Liquid is a Microfluidics Suitable, quadruple-stage ultra-filtered cell culture medium engineered for organ-on-a-chip (OoC), tissue-on-a-chip (ToC), and microphysiological system (MPS) applications. A quadruple-stage train (0.1 µm ×2 + 0.04 µm ×2) reaches a 0.04 µm final cut-off, five times finer than the 0.22 µm membranes used for conventional sterile filtration.

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 with a validated four-stage filtration architecture.
Microchannel-safe purity
0.04 µm final filter retains particulates to sub-mycoplasma size; USP <788> Method 1 (light obscuration) particulate compliance verified per lot.
Total metabolic control
Defined glucose, L-glutamine, and sodium pyruvate levels give precise control over carbon source and metabolic flux experiments.
Ultrapure-grade water
Prepared with Type 1 water (18.2 MΩ·cm), formulated under trace-metal and organic-carbon (TOC) controlled conditions.
Low background for imaging
Phenol red-free formulation with reduced particulate baseline supports confocal microscopy, live-cell biosensors, and TEER measurements.
Rich, stable nutrient profile
Micro-batch precision locks in amino acid and vitamin concentrations for lot-to-lot reproducibility in long-term perfusion studies.
Customization on demand
pH, glucose, salts, HEPES, and full nutrient composition available on request. Contact support@diagnocine.com.
Quadruple-stage filtration system
FluxMPS™ Minimum Essential Medium (MEM), Low Glucose w/o Phenol Red: 1X Liquid is processed through a four-stage serial filtration sequence — two dedicated 0.1 µm/0.04 µm prefilter-and-final-filter pairs in series — reaching a 0.04 µm final pore size that addresses particulate loads standard 0.22 µm filtration cannot.
-
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 through a 0.22 µm filter, including mycoplasma-sized particles (0.2–0.3 µm).
-
3
0.1 µm Prefiltration II
Second dedicated prefilter, protecting the second 0.04 µm final filter cartridge from breakthrough.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill & finish in an ISO Class 5 laminar-flow workstation.
Performance vs. conventional media
Four sequential stages reaching 0.04 µm deliver approximately 5× cleaner media by particulate count compared to single-pass 0.22 µm filtration, with USP <788> Method 1 compliance verified on every lot.
