FluxMPS™ Basal Medium Eagle (BME), 1X Liquid
FluxMPS™ Basal Medium Eagle (BME), 1X Liquid is a Microfluidics Suitable, ultra-filtered cell culture medium manufactured through a validated Quadruple-stage filtration system (0.1 µm ×2 + 0.04 µm ×2) reaching a 0.04 µm final cut-off — five times finer than the 0.22 µm membranes used for conventional sterile filtration. Engineered for microfluidic channels, organ-on-a-chip (OoC), and microphysiological system (MPS) platforms where sub-micron particulates cause sensor drift, microchannel occlusion, and compromised cell viability.

Engineered where standard media fails
Conventional 0.22 µm-filtered Basal Medium Eagle passes mycoplasma-scale particles (0.2–0.3 µm), sub-visible aggregates, and endotoxin fragments that clog microfluidic channels and corrupt downstream biosensor or TEER signals. FluxMPS™ BME addresses these failure modes with a four-stage nanofiltration train and an ISO 13485:2016 quality system.[1,2]
Microchannel-Safe Purity
0.04 µm final filtration removes particles that 0.22 µm membranes miss. USP <788> Method 1 (light obscuration) particulate testing confirms every batch meets its sub-visible particulate release specification, supporting use in microchannel geometries below 100 µm.
Total Metabolic Control
The complete Eagle’s Basal Medium base, with defined D-Glucose and L-Glutamine content, provides a stable carbon and nitrogen source that supports Warburg-effect studies, metabolic flux analysis, and amino acid drop-in experiments.[3]
Ultrapure-Grade Water
Prepared with Ultrapure Type 1 water (18.2 MΩ·cm), minimizing trace-metal ions and organic carbon that can interfere with sensitive metabolomics and electrophysiology readouts.
Low Background for Imaging
The quadruple-stage nanofiltration train keeps the sub-visible particulate baseline low, supporting confocal live-cell imaging, TEER biosensors, and optical microfluidic platforms.[4]
Rich, Stable Nutrient Profile
A complete inorganic salt matrix (NaCl 6,800 mg/L, NaHCO3 2,200 mg/L), 13 amino acids, and 11 vitamin and other components — 30 defined components in total — are micro-batch manufactured for lot-to-lot consistency critical in perfusion-based MPS experiments.
Customization on Demand
pH, glucose concentration, HEPES buffering, salt balance, and nutrient composition are available as custom modifications. Contact support@diagnocine.com for bespoke formulations.
Quadruple-stage filtration system
FluxMPS™ BME is manufactured through a validated four-stage nanofiltration train terminating at a 0.04 µm final cut-off — five times finer than the 0.22 µm membranes used in conventional single-pass filtration. The train runs two dedicated 0.1 µm prefilter + 0.04 µm final-filter pairs in series, each pair providing full redundancy for the one behind it.
-
1
0.1 µm Prefiltration I
First-pass removal of large aggregates, cell debris, and macro-particulates. Extends downstream membrane life and reduces bioburden load ahead of the first 0.04 µm final filter.
-
2
0.04 µm Final Filtration I
First 0.04 µm pass, retaining sub-micron particulates and microaggregates that pass through a 0.22 µm membrane.
-
3
0.1 µm Prefiltration II
Second dedicated 0.1 µm prefilter, protecting the second 0.04 µm cartridge and providing full process redundancy ahead of final filtration.
-
4
0.04 µm Final Filtration II — Polish
Ultimate 0.04 µm polishing pass immediately prior to aseptic fill and finish, reducing sub-visible particulate load before container closure.
Performance vs. conventional media
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. In microfluidic chip experiments with ≤100 µm channels, a finer final pore size supports extended channel patency relative to conventional 0.22 µm-filtered media.

Optimized for next-generation cell platforms
FluxMPS™ BME’s clean formulation, defined ionic balance, and microchannel-safe particulate profile make it a suitable basal medium for demanding research platforms — from organ-on-a-chip perfusion systems to metabolomics and live-cell optical sensing.[1,4,6]
Automated Bioreactors & Robotics
For automated perfusion bioreactors, robotic liquid-handling platforms, and high-throughput microfluidic screening systems, an optional MPS Grade 0.01 µm (10 nm) ultra nano-filtered variant of FluxMPS™ BME is available, adding two further filtration stages beyond this Microfluidics Suitable product’s 0.04 µm cut-off. This grade provides near-absolute exclusion of nanoparticulates, protecting precision valves, flow sensors, and sub-micron microchannels from fouling during extended automated runs.
- Total Particulate Exclusion: 0.01 µm filtration removes nanoparticulates that transit standard 0.04 µm membranes, reducing cumulative fouling in long-duration perfusion experiments
- Valve & Sensor Protection: Ultra-clean media extends the operational lifetime of microfluidic valves, pressure transducers, and optical flow sensors in automated bioreactor systems
- Extended Perfusion Stability: Reduced particulate load supports stable TEER, impedance, and biosensor readings across multi-week perfusion protocols
Inquiry Required: The 0.01 µm (10 nm) MPS Grade is produced on a project basis. To request this specification, contact support@diagnocine.com.
Micro Physiological System (MPS) & Chip
FluxMPS™ BME’s low particulate count and mycoplasma-retentive filtration make it a suitable basal medium for organ-on-a-chip, tissue-on-a-chip, and body-on-a-chip platforms requiring sustained channel patency.[1]
Warburg Effect & Metabolic Research
Defined carbon source and low-endotoxin background support metabolic flux analysis and Warburg effect studies.
iPSC-Derived Models
Low-endotoxin BME base supports defined iPSC differentiation protocols where media impurities can confound epigenetic and transcriptional outcomes in neuronal, cardiomyocyte, and hepatocyte models.[7]
Endothelial & Primary Cells
Defined salt matrix (NaCl 6,800 mg/L, KCl 400 mg/L) supports endothelial monolayer integrity in perfused vascular-chip and tube-formation assays with primary cell cultures.[2]
Metabolic Flux Analysis
A defined, stable nutrient composition provides a clean metabolic background for ¹³C isotope tracing and NMR-based metabolomics. This bicarbonate-buffered formulation is not compatible with Agilent Seahorse XF assays, which require bicarbonate-free, phenol red-free medium.[3,8]
Microscopy & Optical Sensing
Its low particulate baseline supports confocal live-cell imaging, fluorescence-based biosensors, and TEER transepithelial resistance monitoring in transparent microfluidic chips.[4]
