FluxMPS™ MEM, Low Glucose with Earle's Salts w/o L-Glutamine
FluxMPS™ MEM, Low Glucose with Earle's Salts (DCP-MEM-QN1X) is a Microfluidics Suitable Minimum Essential Medium engineered for microphysiological system (MPS), organ-on-a-chip (OoC), and microfluidic applications where conventional 0.22 µm-filtered media fall short. A quadruple-stage filtration 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 — protecting narrow microchannels from blockage while preserving the full nutrient composition needed for demanding cell models.

Engineered where standard media fails
Conventional 0.22 µm-filtered MEM does not exclude mycoplasma-sized organisms (0.2–0.3 µm), subvisible particulates, or ionic impurities that can accumulate in microchannels and compromise morphology in long-duration perfusion cultures. FluxMPS™ adds two additional filtration passes—including a second 0.04 µm final polish—to deliver a medium that is microchannel-safe, ultra-clean, and fully traceable from raw material to fill.[1]
Microchannel-Safe Purity
A 0.04 µm final filter is evaluated for USP <788> Method 1 (Light Obscuration) particulate compliance, reducing the risk of channel blockage and flow resistance drift in organ-on-a-chip devices.[2]
Total Metabolic Control
Low-glucose (1 g/L), L-glutamine-free formulation lets researchers define the amino-acid supply precisely—useful for Warburg-effect, metabolomics, and flux-analysis experiments.
Ultrapure-Grade Water
Prepared with Type 1 Ultrapure water at 18.2 MΩ·cm (ASTM D1193 / ISO 3696), minimizing trace-metal and organic-carbon contribution from the water source.[3]
Low Background for Imaging
A low particulate baseline reduces background scatter in confocal live-cell imaging and integrated biosensor read-outs on chip. Note: this formulation contains phenol red, which itself contributes optical absorbance — select a phenol-red-free variant for fluorescence-sensitive assays.
Rich, Stable Nutrient Profile
Full MEM amino-acid and vitamin suite—including arginine, isoleucine, leucine, lysine, and essential B-vitamins—micro-batch formulated for lot-to-lot consistency and long perfusion stability.
Customization on Demand
pH, glucose concentration, Earle's or Hank's salts, HEPES, NEAA, and calcium level are all adjustable. Request a custom formulation at support@diagnocine.com.
Quadruple-stage filtration system
DCP-MEM-QN1X is filtered through two dedicated 0.1 µm/0.04 µm prefilter-plus-final-filter pairs in series, run in the order 0.1 µm → 0.04 µm → 0.1 µm → 0.04 µm, before an aseptic fill. This paired, redundant architecture reaches a 0.04 µm final cut-off — five times finer than the 0.22 µm membranes used in conventional single-pass sterile filtration.
-
1
0.1 µm Prefiltration I
Removes large particulates, cell debris, and protein aggregates ahead of the first 0.04 µm final filter, protecting downstream membrane capacity and extending filter service life.
-
2
0.04 µm Final Filtration I
First 0.04 µm pass retains sub-micron particulates and mycoplasma-sized organisms (0.2–0.3 µm) that pass unimpeded through a standard 0.22 µm membrane.
-
3
0.1 µm Prefiltration II
A second, dedicated 0.1 µm prefilter protects the final 0.04 µm cartridge from fouling, maintaining consistent flow through the polishing stage.
-
4
0.04 µm Final Filtration II — Polish
Ultimate 0.04 µm polishing filter completes the redundant pair train. Aseptic fill and finish is performed under ISO Class 5 (Class 100) cleanroom conditions.
Performance vs. conventional media
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, helping protect microfluidic channels and sensor surfaces throughout extended perfusion runs.[2]

Designed for next-generation cell models
FluxMPS™ MEM (DCP-MEM-QN1X) supports a broad range of cell types including HeLa, BHK-21, HEK-293, HEP-2, HT-1080, MCF-7, fibroblasts, and primary rat astrocytes.[4] Its low-particulate profile is well suited to microfluidic perfusion systems, metabolic research, and live-cell optical platforms where media purity affects data quality.
Automated Bioreactors & Robotics
For high-throughput automated bioreactor platforms and liquid-handling robotics, an optional 0.01 µm (10 nm) ultra nano-filtered MPS Grade variant of DCP-MEM-QN1X is available on inquiry — a distinct product line from this 0.04 µm Microfluidics Suitable medium. This grade further reduces nanoscale particulates that can foul micro-valves, optical flow sensors, and pressure transducers during continuous perfusion cycles.
- Extended Particulate Exclusion: 0.01 µm filtration retains nano-aggregates that pass standard 0.22 µm and 0.04 µm membranes, protecting sensitive fluidic components.
- Valve & Sensor Protection: Low-particulate media helps reduce fouling of micro-valves, flow meters, and optical windows over long-duration automated runs.
- Extended Perfusion Stability: Reduced particle load supports stable flow resistance and nutrient delivery throughout multi-week automated culture cycles.
Inquiry Required: The 0.01 µm MPS Grade variant is produced on request. Contact support@diagnocine.com to discuss specifications, volume requirements, and lead time.
