FluxMPS™ Dulbecco's Modified Eagle Medium (DMEM), Low Glucose, w/o L-Glutamine, Sodium Bicarbonate: 1X Liquid
FluxMPS™ DCP-DMEML-QB1X is an MPS-grade, ultra-filtered DMEM Low Glucose formulation engineered for microphysiological systems, organ-on-a-chip (OoC), and microfluidic tissue models. Processed through a proprietary Quadruple-stage filtration system (0.1 µm ×2 + 0.04 µm ×2), it delivers particulate counts approximately 5× lower than conventional 0.22 µm–filtered media — ensuring unobstructed microchannel flow, mycoplasma-free media, and low-background optical measurements. Formulation: [+] Low Glucose, [+] Sodium Pyruvate | [-] L-Glutamine, [-] Sodium Bicarbonate.
- 0.04 µm final nano-filtration for sub-mycoplasma particle removal — critical for chip geometries below 100 µm
- Quadruple-stage sequential filtration: 0.1 µm pre-I → 0.04 µm pre-II → 0.1 µm sterile-I → 0.04 µm final polish
- Endotoxin < 0.05 EU/mL (LAL, USP <85>) — 20× below typical cell culture grade
- Formulation: [+] Low Glucose, [+] Sodium Pyruvate | [-] L-Glutamine, [-] Sodium Bicarbonate

Engineered where standard media fails
Conventional 0.22 µm–filtered DMEM passes mycoplasma (0.1–0.3 µm diameter), subvisible particulates, and endotoxin fragments that accumulate inside microfluidic channels, clog chip geometries, and corrupt sensor readings and metabolic signals. FluxMPS™ was designed specifically for these failure modes.
Microchannel-safe purity
0.04 µm final filtration removes sub-micron particles that clog channels below 100 µm. USP <788> particulate compliance ensures safe perfusion in every chip geometry.
Total metabolic control
Low glucose (1.0 g/L) base with user-defined glutamine, pyruvate, and bicarbonate allows precise definition of every carbon and nitrogen source for Warburg-effect and metabolic flux studies.
Ultrapure-grade water
Every batch is prepared using Ultrapure Type 1 water (18.2 MΩ·cm), meeting USP <85> resistivity — eliminating ionic contaminants that interfere with electrophysiology and TEER measurements.
Low background for imaging
Ultra-low particulate count and (in phenol red–free variants) no autofluorescent dye delivers cleaner confocal, widefield, and biosensor baselines on chip.
Rich, stable nutrient profile
4× BME amino acid & vitamin concentrations, micro-batch manufacturing, and lot-to-lot QC ensure reproducible cell growth across multi-day perfusion experiments.
Customization on demand
pH, glucose concentration, salts, HEPES, and nutrient composition are adjustable per your protocol. Contact support@diagnocine.com to specify your formulation.
Quadruple-stage filtration system
The only ready-to-use DMEM at this purity level — four serial filtration stages reaching a final 0.04 µm polish under ISO Class 5 aseptic conditions. No other commercially available DMEM offers this level of particulate exclusion while maintaining full nutrient integrity.
-
1
0.1 µm Pre-filtration I — Large Particulate Removal
Removes large aggregates, cell debris, and contaminants. Extends the service life of downstream 0.04 µm membranes and protects chip geometries from early fouling.
-
2
0.04 µm Pre-filtration II — Mycoplasma Barrier
Retains fine particulates, bacteria, and critically mycoplasma (typical diameter 0.1–0.3 µm) — a key step absent from standard 0.22 µm filtration.
-
3
0.1 µm Sterile-filtration I — Second-pass Redundancy
Second-pass removal of residual contaminants and bioburden. Provides sterility redundancy, ensuring no breakthrough from Stage 1.
-
4
0.04 µm Sterile-filtration II — Final Polish
Ultimate polish for ultra-pure, particle-free, mycoplasma-free media. Final fill performed in a validated ISO Class 5 (Class 100) laminar-flow workstation under aseptic conditions.
Performance vs. conventional media
FluxMPS™ DCP-DMEML-QB1X delivers measurably cleaner media than any standard 0.22 µm–filtered DMEM, addressing the root cause of microchannel fouling, signal noise, and mycoplasma contamination in sensitive MPS workflows.

Endothelial & Primary Cells
Particle-free, endotoxin-controlled DMEM supports HUVEC and primary hepatocyte monolayer integrity, essential for barrier-function assays and TEER monitoring.
Metabolic Flux Analysis
Defined low-glucose formulation with omitted glutamine provides a clean metabolic background for ¹³C isotope tracing and extracellular flux measurement.
