FluxMPS™ Dulbecco's Modified Eagle Medium (DMEM), High Glucose & 25mM HEPES w/o L-Glutamine, Sodium Bicarbonate: 1X Liquid

Contains Phenol Red Contains 25mM HEPES Contains Calcium Contains Magnesium Contains High Glucose (4500 mg/L) Contains Sodium Pyruvate Without L-Glutamine Without Sodium Bicarbonate

FluxMPS™ DCP-DMEMH-QB1X is a Microfluidics Suitable, ultra-filtered DMEM High Glucose (4.5 g/L) formulation with 25 mM HEPES buffer, engineered for organ-on-a-chip (OoC), microphysiological systems (MPS), and CO₂-independent or open-top microfluidic 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. HEPES (25 mM, pKa 7.3 at 37°C) provides robust CO2-independent pH buffering.

Why FluxMPS™

Engineered where standard media fails

Conventional 0.22 µm–filtered DMEM passes mycoplasma-sized organisms, subvisible particulates, and protein aggregates that clog microfluidic channels. Standard DMEM also lacks HEPES buffering, causing pH instability whenever chips are handled outside incubators. FluxMPS™ addresses both failure modes simultaneously.

Microchannel-safe purity

0.04 µm final filtration and USP <788> particulate compliance support safe perfusion across a wide range of chip geometries, including sub-100 µm channels.

High-energy cell support

4.5 g/L glucose sustains energy-demanding cell types — primary neurons, iPSC-derived cardiomyocytes, Warburg-active cancer lines — in long-duration perfusion.

HEPES: CO2-stable pH

25 mM HEPES (pKa 7.3 at 37°C) maintains pH 7.2–7.4 regardless of CO2 fluctuation — useful for open-top chips, point-of-care devices, and atmospheric incubation.

Low background for imaging

Ultra-low particulate baseline supports confocal microscopy and biosensor platforms on chip; particulate control is independent of phenol red content, which is present in this formulation.

FAQ

Frequently asked questions

Common questions about FluxMPS™ DCP-DMEMH-QB1X DMEM High Glucose + 25mM HEPES.

Yes. DCP-DMEMH-QB1X combines Quadruple-stage 0.04 µm filtration for a low-particulate baseline in microfluidic channels with 25 mM HEPES buffering for CO2-stable pH. High glucose (4.5 g/L) supports energy-demanding cell types — neurons, cardiomyocytes, and cancer lines — in long-duration chip perfusion. The HEPES component is particularly valuable for open-top chips where CO2 concentration fluctuates.
 
This formulation is CO2-independent (HEPES alone buffers pH without bicarbonate) and is intended for fresh L-glutamine addition at the time of use (typically 2 mM), since glutamine degrades in liquid storage over time. It is ideal for atmospheric-incubation, open-top chip platforms requiring precise nitrogen control and no CO2 dependency — a common requirement for multi-compartment body-on-a-chip devices.
No. This medium is CO2-independent — HEPES (25 mM) alone maintains pH 7.2–7.4 at 37°C without gas supplementation. HEPES (pKa 7.3 at 37°C) maintains stable pH across a broad CO2 range, making this medium suitable for open-top chips, point-of-care platforms, and atmospheric incubation where CO2 control is impractical.
Yes. FBS (typically 5–10%), serum-free supplements, growth factors, antibiotics, or custom nutrients may be added as required. Filter serum-containing or protein-containing additions through a 0.2 µm low-protein-binding PES or PVDF membrane before use; defined, protein-free additions may use a 0.1 µm membrane. Never use a 0.04 µm membrane for supplement filtration — it will strip serum proteins and clog rapidly. Contact support@diagnocine.com for custom co-formulation.
Endotoxin is controlled per manufacturing batch, not per individual unit. Every batch is tested by LAL assay (USP <85>, Bacterial Endotoxins Test; assay sensitivity 0.005 EU/mL) before release and must meet the release specification of < 0.05 EU/mL. A Certificate of Analysis is available on request.
Yes. A full CoA per lot covers: appearance, pH (USP <791>), osmolality (USP <785>), sterility (USP <71>), endotoxin (USP <85>), mycoplasma filtration status, particulate count (USP <788> Method 1), and raw-material traceability. Request at support@diagnocine.com.
