FluxMPS™ RPMI 1640 Medium, High Glucose w/o Sodium Bicarbonate: 1X Liquid
FluxMPS™ RPMI 1640 Medium, High Glucose w/o Sodium Bicarbonate: 1X Liquid
FluxMPS™ RPMI 1640 Medium, High Glucose w/o 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.

Engineered where standard media fails
Conventional 0.22 µm-filtered media carry mycoplasma-sized particulates (0.2–0.3 µm), subvisible debris, and endotoxin variability that accumulate inside microchannels — corrupting biosensor readings and shortening device lifetimes. FluxMPS™ is built to address these failure modes with a validated four-stage filtration train.
Microchannel-safe purity
0.04 µm final filter retains particulate down to sub-mycoplasma size; USP <788> Method 1 (light obscuration) particulate compliance verified per batch.
Total metabolic control
High glucose (4.5 g/L), defined L-glutamine and sodium pyruvate levels support precise metabolic flux experiments, including Warburg-effect studies.
Ultrapure-grade water
Prepared with Type 1 water (18.2 MΩ·cm) under trace-metal and total-organic-carbon (TOC) control, minimizing extraneous contaminant load from the feed water itself.
Low background for imaging
Quadruple-stage filtration reduces the particulate baseline entering the culture system, supporting confocal microscopy, live-cell biosensors, and TEER-based assays.
Rich, stable nutrient profile
Micro-batch precision manufacturing locks in amino acid and vitamin concentrations, supporting lot-to-lot reproducibility for long-term perfusion studies.
Customization on demand

Quadruple-stage filtration system
FluxMPS™ RPMI 1640 Medium, High Glucose w/o Sodium Bicarbonate: 1X Liquid is processed through a validated four-pass filtration train — two paired prefilter + final-filter stages — reaching a 0.04 µm final pore size. This addresses mycoplasma-sized particulates and subvisible debris 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 cartridge.
-
2
0.04 µm Final filtration I
First 0.04 µm pass; retains sub-micron particulates and microaggregates, including mycoplasma-sized material (0.2–0.3 µm), that pass through a 0.22 µm filter.
-
3
0.1 µm Prefiltration II
Second dedicated prefilter, protecting the second 0.04 µm cartridge and providing full-train redundancy.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill & finish under ISO Class 5 (Class 100) laminar-flow conditions.
Performance vs. conventional media
Two prefilter + final-filter pairs run in series — four passes total — reaching a 0.04 µm final pore size and delivering approximately 5× cleaner media by particulate count compared to single-pass 0.22 µm filtration.

Micro Physiological System (MPS) & Chip
Ultra-filtered formulation reduces the risk of microchannel clogging and helps maintain laminar flow integrity.
Warburg Effect & Metabolic Research
High glucose (4.5 g/L) and a defined nutrient background support metabolic flux analysis in glycolytic cell models.
iPSC-Derived Models
Ultra-filtered formulation supports sensitive iPSC differentiation protocols requiring low particulate and endotoxin background.
Endothelial & Primary Cells
Microchannel-safe purity supports endothelial barrier integrity and TEER-based monitoring in perfused culture systems.
Metabolic Flux Analysis
Defined glucose, glutamine, and pyruvate levels support isotope tracing and NMR-based metabolomics workflows. Not compatible with Agilent Seahorse XF assays, which require bicarbonate-free, phenol red-free medium — this formulation contains phenol red.
