FluxMPS™ Minimum Essential Medium (MEM), High Glucose w/o Sodium Pyruvate, Sodium Bicarbonate: 1X Liquid
FluxMPS™ Minimum Essential Medium (MEM), High Glucose w/o Sodium Pyruvate, Sodium Bicarbonate: 1X Liquid
FluxMPS™ Minimum Essential Medium (MEM), High Glucose w/o Sodium Pyruvate, Sodium Bicarbonate: 1X Liquid is a Microfluidics Suitable, ultra-filtered cell culture medium engineered for organ-on-a-chip (OoC), tissue-on-a-chip (ToC), and microphysiological system (MPS) applications. It is processed through a Quadruple-stage filtration system (0.1 µm ×2 + 0.04 µm ×2) reaching a 0.04 µm final cut-off — well beyond conventional 0.22 µm-filtered media — making it microchannel-safe for precision fluidic systems.
- High-glucose (4.5 g/L) MEM formulation with L-glutamine (292 mg/L) and a phenol red pH indicator — suited to high-energy-demand cell types
- Quadruple-stage filtration train (0.1 µm ×2 + 0.04 µm ×2) reaching a 0.04 µm final cut-off for microchannel-safe purity
- Endotoxin release specification < 0.05 EU/mL, controlled per manufacturing batch via LAL assay (USP <85>)
- pH 7.4 (USP <791>); formulated without sodium pyruvate and without sodium bicarbonate
- Manufactured under an ISO 13485:2016 quality management system, with final QC and packaging at Diagnocine, Totowa, NJ
- Custom formulations available on request — adjust pH, glucose, salts, HEPES, and nutrient composition

Engineered where standard media fails
Conventional 0.22 µm-filtered media carry mycoplasma-sized organisms (0.2–0.3 µm), subvisible debris, and variable endotoxin loads that accumulate inside microchannels — corrupting biosensor readings and shortening device lifetimes. FluxMPS™ is built to address these failure modes.
Microchannel-safe purity
The 0.04 µm final filter removes particulates down to sub-mycoplasma size; particulate levels are evaluated under USP <788> Method 1 (light obscuration) testing.
High-glucose metabolic support
4.5 g/L glucose supports high-energy-demand cell types including HeLa, MCF-7, fibroblasts, and iPSC-derived models in perfusion devices.
Ultrapure-grade water
Prepared with Type 1 water (18.2 MΩ·cm) with controlled trace-metal and total organic carbon (TOC) levels, reducing extraneous contaminants in sensitive culture systems.
Low background for imaging
Quadruple-stage filtration reduces particulate background, supporting confocal microscopy, live-cell biosensors, and TEER measurements. Note: this formulation contains phenol red, which contributes to background absorbance in some optical assays — a phenol-red-free formulation is available on request.
Rich, stable nutrient profile
A comprehensive amino acid and vitamin profile combined with micro-batch precision manufacturing supports lot-to-lot nutrient consistency for demanding cell culture models.
Customization on demand

Quadruple-stage filtration system
FluxMPS™ Minimum Essential Medium (MEM), High Glucose w/o Sodium Pyruvate, Sodium Bicarbonate: 1X Liquid is processed through a four-stage filtration train — two dedicated prefilter/final-filter pairs — reaching a 0.04 µm final cut-off, addressing mycoplasma-sized organisms and subvisible particulates that 0.22 µm filtration does not 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 organisms in the mycoplasma size range (0.2–0.3 µm), that pass a 0.22 µm filter.
-
3
0.1 µm Prefiltration II
A second, dedicated prefilter protecting the second 0.04 µm final-filter cartridge — not a polish of Stage 2 effluent, but redundant protection for Stage 4.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill performed in a validated ISO Class 5 laminar-flow workstation.
Performance vs. conventional media
Two prefilter/final-filter pairs in series (0.1 µm ×2 + 0.04 µm ×2), reaching a 0.04 µm final pore size, provide substantially lower particulate counts than single-pass 0.22 µm filtration, with particulate levels checked under USP <788> Method 1 on every production lot.
