FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES w/o L-Glutamine, Sodium Pyruvate, Sodium Bicarbonate, Phenol Red: 1X Liquid
FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES w/o L-Glutamine, Sodium Pyruvate, Sodium Bicarbonate, Phenol Red: 1X Liquid is a Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) 1X liquid 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 lot-to-lot endotoxin variability that accumulate inside microchannels — corrupting biosensor readings, triggering inflammation in primary cultures, and shortening device lifetimes. FluxMPS™ is built to address these failure modes at the filtration stage.
Microchannel-safe purity
0.04 µm final filter retains particles to sub-mycoplasma size; USP <788> particulate compliance verified per lot.
Total metabolic control
A defined low-glucose carbon source (1000 mg/L) with L-glutamine, sodium pyruvate, and bicarbonate withheld gives precise control for metabolic flux experiments and Warburg-effect studies.
Ultrapure-grade water
Prepared with Type 1 water (18.2 MΩ·cm) under strict trace-metal and organic-carbon (TOC) control, supporting sensitive downstream assays.
Low background for imaging
Quadruple-stage filtration delivers an ultra-low particulate baseline for confocal microscopy, live-cell biosensors, and TEER measurements. Note: riboflavin in this formulation contributes inherent autofluorescence near 525 nm.
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

Quadruple-stage filtration system
FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES w/o L-Glutamine, Sodium Pyruvate, Sodium Bicarbonate, Phenol Red: 1X Liquid is processed through a validated four-stage serial filtration train reaching a 0.04 µm final cut-off — two paired prefilter-plus-final-filter passes, addressing particulates and mycoplasma-sized organisms that a single 0.22 µm pass cannot retain.
-
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, including mycoplasma-sized organisms (0.2–0.3 µm), that pass through 0.22 µm filtration.
-
3
0.1 µm Prefiltration II
Second dedicated prefilter protecting the second 0.04 µm cartridge; guards against breakthrough reaching the final polish.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill and finish in a validated 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> compliance verified on every lot.
