FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES w/o Sodium Bicarbonate: 1X Liquid

Contains L-Glutamine Contains Phenol Red Contains HEPES Contains Calcium Contains Magnesium Contains Glucose Contains Sodium Pyruvate Without Sodium Bicarbonate

FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES w/o Sodium Bicarbonate: 1X Liquid 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), tissue-on-a-chip (ToC), and microphysiological system (MPS) applications. 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.

Why FluxMPS™

Engineered where standard media fails

Conventional 0.22 µm-filtered media carry mycoplasma-sized particulates (0.2–0.3 µm), subvisible debris, and endotoxin variability that accumulate inside microchannels — corrupting biosensor readings and shortening device lifetimes. FluxMPS™ is built to reduce these failure modes at the filtration stage.

Purity Architecture

Quadruple-stage filtration system

FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES w/o Sodium Bicarbonate: 1X Liquid is processed through a validated four-stage serial filtration sequence reaching 0.04 µm — addressing mycoplasma-sized particulates and subvisible particles that 0.22 µm filtration does not retain.

  1. 1

    0.1 µm Prefiltration I

    Removes large particulates and protein aggregates; protects the first 0.04 µm final filter cartridge.

  2. 2

    0.04 µm Final filtration I

    First 0.04 µm pass; retains sub-micron particulates and mycoplasma-sized material (0.2–0.3 µm) that pass a 0.22 µm filter.

  3. 3

    0.1 µm Prefiltration II

    Second dedicated prefilter, protecting the second 0.04 µm final-filter cartridge.

  4. 4

    0.04 µm Final filtration II — Polish

    Ultimate polishing filter; aseptic fill in a validated ISO Class 5 laminar-flow workstation.

Performance vs. conventional media

Two prefilter + final-filter pairs reaching 0.04 µm deliver approximately 5× cleaner media by particulate count compared to single-pass 0.22 µm filtration, with USP <788> Method 1 compliance verified on every lot.

FAQ

Frequently asked questions

Common questions about FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES w/o Sodium Bicarbonate: 1X Liquid and Microfluidics Suitable cell culture media.

Yes. DCP-MEMH-BN1X uses our Quadruple-stage filtration (0.1 µm ×2 + 0.04 µm ×2), delivering ultra-low particulate counts that reduce the risk of microchannel clogging in OoC and MPS devices.
Standard 0.22 µm filtration leaves intact mycoplasma-sized material (0.2–0.3 µm) and subvisible particulates that can accumulate in microchannels. FluxMPS™ uses four sequential stages reaching 0.04 µm, delivering approximately 5× lower particulate counts per USP <788> Method 1.
This formulation is buffered with 25 mM HEPES instead of sodium bicarbonate, reducing dependence on a controlled CO2 atmosphere. It retains 1000 mg/L glucose, 292 mg/L L-glutamine, and 110 mg/L sodium pyruvate as supplied. If your protocol requires bicarbonate buffering, contact support@diagnocine.com for a custom formulation.
This formulation is HEPES-buffered, reducing CO2 dependence. Standard 5–10% CO2 incubation remains compatible; validate against your specific cell line.
Yes. This formulation can be supplemented with FBS (5–20%), growth factors, antibiotics, or other additives per standard practice. Add supplements immediately before use. When adding serum or protein-containing components, filter through a 0.2 µm low-protein-binding PES or PVDF membrane if additional sterility assurance is needed — do not use a 0.04 µm membrane, as it will retain serum proteins and lipoproteins.
Endotoxin is controlled per manufacturing batch rather than per unit. Every batch is tested by LAL assay (USP <85> BET; assay sensitivity 0.005 EU/mL) before release and must meet the specification: < 0.05 EU/mL. Lot-specific Certificates of Analysis are available from support@diagnocine.com.
Yes. A lot-specific CoA is available for every shipment and includes: appearance, pH (USP <791>), osmolality (USP <785>), endotoxin (USP <85> BET), sterility (USP <71>), particulate matter (USP <788> Method 1), raw material traceability, manufacturing date, and authorized release signatures.
