FluxMPS™ Dulbecco's Modified Eagle Medium (DMEM), Low Glucose, 25mM HEPES w/o L-Glutamine, Sodium Pyruvate, Phenol Red: 1X Liquid
FluxMPS™ DCP-DMEMLH-QPR1X is a Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) DMEM Low Glucose + HEPES formulation engineered for microphysiological systems (MPS), organ-on-a-chip (OoC), and microfluidic tissue models. 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. Formulation: [+] Low Glucose, [+] Sodium Bicarbonate, [+] 25mM HEPES, [+] Calcium, [+] Magnesium | [-] L-Glutamine, [-] Sodium Pyruvate, [-] Phenol Red. The 25 mM HEPES (pKa 7.3 at 37°C) supplements the standard sodium bicarbonate buffer system, adding bench-top pH stability during handling outside the CO₂ incubator.
- Formulated as DMEM Low Glucose (1000 mg/L D-Glucose) with 25 mM HEPES; sodium bicarbonate present at the standard 3700 mg/L DMEM concentration for a dual-buffer pH system
- L-Glutamine, sodium pyruvate and phenol red are not added — full researcher control over nitrogen source, pyruvate supplementation, and colorimetric background
- Processed through a Quadruple-stage filtration train — 0.1 µm prefilter + 0.04 µm final filter, repeated twice — reaching a 0.04 µm final pore size validated for microfluidic channel geometries
- Endotoxin release specification < 0.05 EU/mL per batch (LAL assay, USP <85>); controlled at the manufacturing-batch level
- Manufactured under an ISO 13485:2016 quality management system with a per-lot Certificate of Analysis; final QC performed at Diagnocine, Totowa, NJ

Engineered where standard media fails
Conventional 0.22 µm–filtered media passes mycoplasma-sized particles, subvisible particulates, and aggregate fragments that clog microfluidic channels and interfere with sensor signals. FluxMPS™ DCP-DMEMLH-QPR1X mitigates these failure modes with a four-stage filtration train reaching a 0.04 µm final pore size, and pairs 25 mM HEPES with the standard bicarbonate buffer system for added bench-top pH stability.
Microchannel-safe purity
0.04 µm final filtration; USP <788> Method 1 (light obscuration) particulate compliance supports safe perfusion across a range of chip geometries.
Total metabolic control
Selective inclusion/exclusion of glutamine, pyruvate, bicarbonate, and HEPES gives precise, researcher-defined nutrient and buffer definition for downstream supplementation.
Ultrapure-grade water
Ultrapure Type 1 water (18.2 MΩ·cm) with rigorous trace-metal and total organic carbon (TOC) control, supporting sensitive cell-signaling and biosensor work.
Low background for imaging
An ultra-low particulate baseline (0.04 µm final filtration) reduces particulate-driven optical interference for confocal microscopy and biosensor measurements. Note: riboflavin in the vitamin mix retains its native fluorescence.
Rich, stable nutrient profile
31 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 prefilter + final-filter pairs — reach a final 0.04 µm polish, delivering low-particulate, mycoplasma-retentive purity for microfluidic channel geometries.
