Engineered where standard media fails
Conventional 0.22 µm filtered media allows mycoplasma (0.1–0.3 µm), sub-visible particulates, and microaggregates to pass freely — clogging microchannels, corrupting biosensors, and invalidating metabolic assays. FluxMPS™ closes that gap.
Microchannel-safe purity
0.04 µm final filter and USP <788> particulate compliance ensure unobstructed flow in channels as narrow as 50 µm.
Total metabolic control
Precisely defined carbon sources enable Warburg-effect studies, glycolysis inhibition, and ¹³C metabolic tracing without background noise.
Ultrapure-grade water
Prepared with Ultrapure Type 1 water (18.2 MΩ·cm, USP <85>) — eliminating ionic interference in TEER and electrochemical biosensors.
Low background for imaging
Ultra-low particulate baseline for pristine confocal live-cell imaging, fluorescent biosensors, and automated high-content analysis on chip.
Rich, stable nutrient profile
4× BME amino acid and vitamin concentrations with micro-batch precision — tight lot-to-lot consistency for long-duration MPS perfusion.
Customization on demand
pH, glucose, HEPES, salts, and nutrients adjusted on request. Contact support@diagnocine.com.
Quadruple-stage filtration system
The only ready-to-use cell culture medium with a validated four-stage sequential filtration reaching a final pore size of 0.04 µm — capturing what 0.22 µm filtration misses entirely.
-
1
0.1 µm Pre-filtration I
Removes large particulates, cell debris, and protein aggregates. Protects downstream fine filters and preserves microchannel chip geometries.
-
2
0.04 µm Pre-filtration II
Retains fine particulates, bacteria, and mycoplasma (typical diameter 0.1–0.3 µm) — entirely absent from standard 0.22 µm media.
-
3
0.1 µm Sterile-filtration I
Second-pass redundant sterile filtration for validated double bioburden clearance.
-
4
0.04 µm Sterile-filtration II — Final Polish
Ultimate polishing filter; aseptic fill in validated ISO Class 5 (Class 100) laminar-flow workstation.
Performance vs. conventional media
By USP <788> Method 2, FluxMPS™ delivers ~5× fewer particles ≥10 µm vs standard 0.22 µm filtered media — the difference between successful long-duration perfusion and channel occlusion within 48 h.
