FluxMPS™ Dulbecco's Modified Eagle Medium (DMEM), Low Glucose, 25mM HEPES w/o Sodium Bicarbonate: 1X Liquid
FluxMPS™ DCP-DMEMLH-B1X 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. The formulation is bicarbonate-free and buffered entirely by 25 mM HEPES (pKa 7.3 at 37°C), giving stable, CO₂-independent pH control for open-top chip architectures. 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.

Engineered where standard media fails
Conventional 0.22 µm–filtered media passes mycoplasma-sized organisms, subvisible particulates, and protein aggregates that clog microfluidic channels and interfere with optical and electrical sensors. FluxMPS™ addresses these failure modes with a four-stage 0.1 µm / 0.04 µm filtration train. HEPES buffering removes CO₂ dependency, supporting open-top chip architectures and atmospheric incubation.
Microchannel-safe purity
0.04 µm final filtration with USP <788> Method 1 (light obscuration) particulate compliance supports safe perfusion through narrow chip geometries.
Total metabolic control
Selective inclusion of low glucose, glutamine, sodium pyruvate and HEPES, with sodium bicarbonate excluded, for precise nutrient and buffer definition.
Ultrapure-grade water
Ultrapure Type 1 water (18.2 MΩ·cm) processed with rigorous trace-metal and total organic carbon (TOC) control, minimizing background chemical interference.
Low background for imaging
Ultra-low particulate baseline (USP <788> compliant) supports confocal microscopy and biosensor-based assays that require a clean optical field.
Rich, stable nutrient profile
33 ingredients verified per lot; micro-batch production with full raw-material traceability.
Customization on demand
pH, glucose, salts, HEPES, and nutrients adjustable per protocol. Contact support@diagnocine.com.
Quadruple-stage filtration system
Four serial filtration stages reaching a final 0.04 µm polish under ISO Class 5 aseptic fill conditions, delivering ultra-low particulate and mycoplasma-retentive purity for microfluidic-channel applications.
