FluxMPS™ Dulbecco's Modified Eagle Medium (DMEM), Low Glucose, 25mM HEPES w/o L-Glutamine, Phenol Red: 1X Liquid
FluxMPS™ DCP-DMEMLH-QR1X is a Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) 1X liquid DMEM Low Glucose + 25 mM HEPES formulation, engineered for microphysiological systems (MPS), organ-on-a-chip (OoC), and microfluidic tissue models. The formulation omits L-glutamine and phenol red for fresh-supplementation and imaging-clean workflows, and combines 44 mM sodium bicarbonate with 25 mM HEPES for buffering flexibility across incubator and open-bench handling. 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.
- Formulated with low glucose (1.0 g/L; 5.55 mM), 110 mg/L sodium pyruvate, and 3700 mg/L sodium bicarbonate, plus 25 mM HEPES (pKa 7.3 at 37°C) for dual-buffer flexibility
- Manufactured without L-glutamine (add fresh at time of use) and without phenol red, for imaging-clean, autofluorescence-conscious workflows
- Quadruple-stage filtration train — 0.1 µm → 0.04 µm → 0.1 µm → 0.04 µm — reaching a 0.04 µm final cut-off validated for microfluidic channel geometries
- Endotoxin release specification < 0.05 EU/mL (LAL, USP <85>), controlled per manufacturing batch
- Sterility confirmed by 14-day USP <71> incubation with no growth
- Manufactured under an ISO 13485:2016 quality management system; final QC and release at Diagnocine, Totowa, NJ

Engineered where standard media fails
Conventional 0.22 µm–filtered media passes mycoplasma, subvisible particulates, and endotoxin fragments that clog microfluidic channels and corrupt sensor signals. FluxMPS™ targets these failure modes with four-stage sub-0.04 µm filtration. The dual bicarbonate/HEPES buffer system supports both closed-incubator and open-top chip handling.
Microchannel-safe purity
0.04 µm final filtration; USP <788> Method 1 (light obscuration) particulate compliance supports safe perfusion across chip geometries.
Total metabolic control
Selective inclusion/exclusion of glutamine, pyruvate, bicarbonate, and HEPES for precise nutrient and buffer definition. Cross-check the composition table before supplementing.
Ultrapure-grade water
Ultrapure Type 1 water (18.2 MΩ·cm) minimizes trace-metal and total organic carbon (TOC) background introduced during formulation.
Low background for imaging
Ultra-low particulate baseline supports confocal microscopy and biosensor applications requiring minimal scatter background.
Rich, stable nutrient profile
32 ingredients verified per lot; micro-batch production with full raw-material traceability.
Customization on demand
pH, glucose, salts, HEPES, and nutrients adjustable per your protocol. Contact support@diagnocine.com.
Quadruple-stage filtration system
Four serial filtration stages — two dedicated prefilter/final-filter pairs — reaching a final 0.04 µm polish, delivering purity levels not achieved by conventional single-pass 0.22 µm filtered media.
