FluxMPS™ RPMI 1640 Medium, High Glucose & 25mM HEPES w/o Sodium Pyruvate, Sodium Bicarbonate, Phenol Red: 1X Liquid
FluxMPS™ DCP-RPMIGH-PBR1X is a Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) 1X liquid cell culture medium engineered for organ-on-a-chip (OoC) and microphysiological system (MPS) platforms. 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.
- High glucose (4500 mg/L / 4.5 g/L) with 300 mg/L L-glutamine for robust energetic and biosynthetic support
- 25 mM HEPES buffering (5958 mg/L) enables stable pH outside a CO₂ incubator — suited to open microfluidic and OoC perfusion systems
- Formulated without sodium pyruvate, sodium bicarbonate, or phenol red for direct control of carbon-source and buffer inputs, plus low-background optical readouts
- Quadruple-stage filtration (0.1 µm ×2 + 0.04 µm ×2) reaching a validated 0.04 µm final polish
- Endotoxin release specification < 0.05 EU/mL (LAL, USP <85>), controlled per manufacturing batch
- 38 verified ingredients per lot with full CAS traceability across inorganic salts, amino acids, vitamins and other components
- Manufactured under an ISO 13485:2016 quality management system with full lot traceability

Engineered where standard media fails
Conventional 0.22 µm–filtered media passes mycoplasma-scale particles, subvisible particulates, and endotoxin fragments that confound sensitive on-chip assays.
Microchannel-safe purity
0.04 µm final filtration; USP <788> Method 1 (light obscuration) particulate compliance. Low-particulate media for OoC microfluidic chips.
Total metabolic control
Supplied without sodium pyruvate and sodium bicarbonate, so glucose and HEPES buffering are the defined carbon and pH inputs — giving you direct control over metabolic conditions.
Ultrapure-grade water
Type 1 water, 18.2 MΩ·cm resistivity, controlled for trace metals and total organic carbon (TOC) at the manufacturing source.
Low background for imaging
Ultra-low particulate baseline for confocal, biosensor, and live-cell imaging applications on-chip.
Rich, stable nutrient profile
38 verified ingredients per lot. Full CAS traceability. Micro-batch precision 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-and-final-filter pairs — reach a final 0.04 µm polish, delivering a substantially cleaner particulate baseline than single-pass 0.22 µm–filtered media.
-
1
0.1 µm Prefiltration I
Removes large aggregates and debris; protects the first 0.04 µm final-filter cartridge downstream.
-
2
0.04 µm Final filtration I
First 0.04 µm pass; retains sub-micron particulates and microaggregates that pass a standard 0.22 µm filter.
-
3
0.1 µm Prefiltration II
A second, dedicated prefilter protecting the second 0.04 µm cartridge — not a polish of the first pass, but redundant protection for the next.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill under ISO Class 5 (Class 100) conditions. Final product QC release gate.
