FluxMPS™ Dulbecco's Modified Eagle Medium (DMEM) w/o Glucose, L-Glutamine: 1X Liquid
FluxMPS™ Dulbecco's Modified Eagle Medium (DMEM) w/o Glucose, L-Glutamine: 1X Liquid
Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) 1X liquid cell culture medium engineered for microfluidic channels, organ-on-a-chip (OoC), and microphysiological systems (MPS). Manufactured under ISO 13485:2016 in an ISO Class 5 fill environment using Ultrapure Type 1 water (18.2 MΩ·cm). 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.
- Quadruple-stage filtration to a 0.04 µm final pore size (0.1 µm ×2 + 0.04 µm ×2) — mycoplasma-retentive, sub-micron particulate control
- Endotoxin release specification: < 0.05 EU/mL (LAL, USP <85>)
- Glucose- and L-glutamine-free formulation supplemented with 110 mg/L sodium pyruvate as the defined carbon/energy source — suited to Warburg-effect and metabolic flux studies

Engineered where standard media fails
Conventional 0.22 µm filtered media allows mycoplasma (0.2–0.3 µm), sub-visible particulates, and microaggregates to pass freely — clogging microchannels, corrupting biosensors, and invalidating metabolic assays. FluxMPS™ closes that gap.
Microchannel-safe purity
0.04 µm final filtration supports unobstructed flow in narrow microfluidic channels; USP <788> Method 1 light-obscuration testing confirms sub-visible particulate control.
Total metabolic control
Defined carbon-source formulation (glucose- and glutamine-free, pyruvate-supplemented) enables Warburg-effect studies, glycolysis inhibition, and 13C metabolic tracing.
Ultrapure-grade water
Prepared with Ultrapure Type 1 water (18.2 MΩ·cm) for tight trace-metal and organic-carbon (TOC) control.
Low background for imaging
Low particulate baseline supports confocal live-cell imaging, fluorescent biosensors, and automated high-content analysis on chip.
Rich, stable nutrient profile
4× BME amino acid and vitamin concentrations with micro-batch precision — tight lot-to-lot consistency for long-duration MPS perfusion.
Customization on demand
pH, glucose, HEPES, salts, and nutrients adjusted on request. Contact support@diagnocine.com.
Quadruple-stage filtration system
FluxMPS™ runs a validated four-stage sequential filtration reaching a final pore size of 0.04 µm — two repeated prefilter-plus-final-filter pairs, capturing sub-micron particulates and mycoplasma that standard 0.22 µm filtration passes through.
-
1
0.1 µm Prefiltration I
Removes large particulates, cell debris, and protein aggregates. Protects the first 0.04 µm final filter and preserves microchannel chip geometries.
-
2
0.04 µm Final filtration I
Retains fine particulates, bacteria, and mycoplasma-sized organisms (typical diameter 0.2–0.3 µm) missed entirely by standard 0.22 µm media.
-
3
0.1 µm Prefiltration II
A second, dedicated prefilter protecting the second 0.04 µm cartridge in the redundant filtration pair.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill in a validated ISO Class 5 (Class 100) laminar-flow workstation.
Performance vs. conventional media
FluxMPS™ delivers approximately 5× fewer particles ≥10 µm compared with standard 0.22 µm filtered media — the difference between successful long-duration perfusion and channel occlusion.
