FluxMPS™ RPMI 1640 Medium, High Glucose & 25mM HEPES w/o L-Glutamine, Phenol Red: 1X Liquid
FluxMPS™ DCP-RPMIGH-QR1X is a Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) 1X liquid RPMI 1640 formulation engineered for organ-on-a-chip (OoC) and microphysiological system (MPS) platforms. High glucose (4500 mg/L) and a dual sodium bicarbonate/25 mM HEPES buffer system deliver stable pH 7.4 performance, while the 0.04 µm final polish reduces sub-micron particulate carryover relative to conventional 0.22 µm–filtered media.
- High glucose (4500 mg/L) RPMI 1640 base with 25 mM HEPES and 23.8 mM sodium bicarbonate for dual-buffer pH stability at 7.4
- L-Glutamine and phenol red excluded from the base formulation — supplement L-Glutamine or GlutaMAX™ per your cell line's requirements
- Quadruple-stage filtration (0.1 µm ×2 + 0.04 µm ×2) reaching a 0.04 µm final polish for microfluidic and OoC channel safety

Engineered where standard media fails
Conventional 0.22 µm–filtered media passes mycoplasma-sized organisms, subvisible particulates, and lot-to-lot endotoxin variability that confound sensitive cell assays.
Microchannel-safe purity
0.04 µm final filtration paired with USP <788> particulate compliance, reducing subvisible particulate load for OoC microfluidic chips.
Total metabolic control
High glucose plus sodium pyruvate gives a defined carbon-source base, while L-Glutamine is left out so you can dose it precisely for your cell line.
Ultrapure-grade water
Type 1 water, 18.2 MΩ·cm resistivity, produced with rigorous trace-metal and organic-carbon (TOC) control at the point of manufacture.
Low background for imaging
Ultra-low particulate baseline supports confocal, biosensor, and live-cell imaging applications on-chip.
Rich, stable nutrient profile
39 verified ingredients per lot across inorganic salts, amino acids, vitamins and other supplements. Full CAS traceability, micro-batch manufacturing.
Customization on demand
pH, nutrient concentrations, HEPES, and component modifications available. Contact support@diagnocine.com.
Quadruple-stage filtration system
Four serial filtration stages — two dedicated prefilter/final-filter pairs — reach a final 0.04 µm polish, giving full redundancy against sub-micron particulate and mycoplasma-sized organisms.
-
1
0.1 µm Prefiltration I — Large Particulate Removal
Removes large aggregates and debris; protects the first 0.04 µm final-filter cartridge and extends its service life.
-
2
0.04 µm Final filtration I — Mycoplasma-Retentive Polish
First 0.04 µm pass; retains sub-micron particulates and organisms in the mycoplasma size range (0.2–0.3 µm) that a standard 0.22 µm filter does not.
-
3
0.1 µm Prefiltration II — Second-Pass Protection
A second, dedicated prefilter protecting the second 0.04 µm 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 & finish in an ISO Class 5 (Class 100) environment. Final product QC release gate.
Performance vs. conventional media
FluxMPS™ DCP-RPMIGH-QR1X runs two 0.1 µm/0.04 µm prefilter/final-filter pairs in series, a train that standard single-pass 0.22 µm–filtered media does not use.

OoC and MPS Applications
FluxMPS™ DCP-RPMIGH-QR1X delivers 0.04 µm-filtered purity for organ-on-a-chip, tissue-on-a-chip, and microfluidic cell culture applications.
Automated Bioreactors & Robotics
An optional 0.01 µm (10 nm) ultra nano-filtered MPS Grade variant of this formulation is available on request for automated bioreactors and robotic perfusion systems where valve and sensor fouling is a limiting factor.
- Total Particulate Exclusion: 0.01 µm filtration removes nanoparticulate aggregates that foul automated systems
- Valve & Sensor Protection: Reduces micro-fouling risk in automated perfusion and recirculation systems
- Extended Perfusion Stability: Consistent nutrient delivery over long-duration culture runs
Inquiry Required: Contact support@diagnocine.com to request the 0.01 µm MPS Grade variant.
