Engineered where standard media fails
Conventional 0.22 µm-filtered media carry mycoplasma-sized particulates (0.2–0.3 µm), subvisible debris, and inconsistent endotoxin levels that accumulate inside microchannels — corrupting biosensor readings, triggering inflammation in primary cultures, and shortening device lifetimes. FluxMPS™ is engineered to address these failure modes at the source.
Microchannel-safe purity
0.04 µm final filter retains particles to sub-mycoplasma size; USP <788> particulate compliance verified per lot.
High-glucose metabolic support
4.5 g/L glucose supports high-energy-demand cell types including HeLa, MCF-7, fibroblasts, and iPSC-derived models in perfusion devices.
Ultrapure-grade water
Prepared with Type 1 water (18.2 MΩ·cm) under controlled trace-metal and organic-carbon (TOC) specifications for consistent, reproducible formulations.
Low background for imaging
Low particulate baseline from 0.04 µm final filtration supports confocal microscopy, live-cell biosensors, and TEER measurements with minimal particulate interference.
Rich, stable nutrient profile
13 amino acids and 8 B-vitamins at MEM Eagle basal concentrations, produced under micro-batch precision for consistent nutrient profile across lots.
Customization on demand
pH, glucose, salts, HEPES, and full nutrient composition available on request. Contact support@diagnocine.com.
Quadruple-stage filtration system
FluxMPS™ Minimum Essential Medium (MEM), High Glucose & 25mM HEPES w/o Sodium Pyruvate, Sodium Bicarbonate, Phenol Red: 1X Liquid is processed through a four-stage serial filtration train reaching a 0.04 µm final pore size — two dedicated prefilter + final-filter pairs run in series, addressing mycoplasma-sized particulates and subvisible debris that 0.22 µm filtration cannot retain.
-
1
0.1 µm Prefiltration I
Removes large particulates, cell debris and protein aggregates; protects the first 0.04 µm final-filter cartridge.
-
2
0.04 µm Final filtration I
First 0.04 µm pass; retains sub-micron particulates and microaggregates that pass through a 0.22 µm filter.
-
3
0.1 µm Prefiltration II
Second dedicated prefilter, protecting the second 0.04 µm final-filter cartridge and providing full train redundancy.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill and finish performed in a validated ISO Class 5 laminar-flow workstation.
Performance vs. conventional media
Four sequential stages reaching a 0.04 µm final pore size deliver approximately 5× cleaner media by particulate count compared to single-pass 0.22 µm filtration, with USP <788> compliance verified on every production lot.
