FluxMPS™ RPMI 1640 Medium, High Glucose w/o L-Glutamine, Sodium Bicarbonate, Phenol Red: 1X Liquid
FluxMPS™ RPMI 1640 Medium, High Glucose w/o L-Glutamine, Sodium Bicarbonate, Phenol Red: 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.

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, triggering inflammation in primary cultures, and shortening device lifetimes. FluxMPS™ is built to reduce these failure modes at the filtration stage.
Microchannel-safe purity
0.04 µm final filter targets particles down to sub-mycoplasma size; USP <788> Method 1 (light obscuration) particulate compliance verified per lot.
Total metabolic control
Defined glucose (4.5 g/L) and sodium pyruvate (110 mg/L) concentrations, without L-glutamine or bicarbonate, support user-controlled metabolic flux and carbon-source experiments.
Ultrapure-grade water
Prepared with Type 1 water (18.2 MΩ·cm, ASTM D1193 Type I), supporting a clean, low trace-metal formulation base.
Low background for imaging
Ultra-low particulate baseline supports high-content confocal microscopy, live-cell biosensors, and TEER measurements. Note: this formulation contains riboflavin, which carries intrinsic autofluorescence — validate imaging channels accordingly.
Rich, stable nutrient profile
Micro-batch precision manufacturing locks in amino acid and vitamin concentrations, supporting lot-to-lot reproducibility for long-term perfusion studies.
Customization on demand
pH, glucose, salts, HEPES, and full nutrient composition available on request. Contact support@diagnocine.com.
Quadruple-stage filtration system
FluxMPS™ RPMI 1640 Medium, High Glucose w/o L-Glutamine, Sodium Bicarbonate, Phenol Red: 1X Liquid is processed through a four-stage serial filtration train — two dedicated 0.1 µm/0.04 µm prefilter-and-final-filter pairs in series — reaching a 0.04 µm final pore size.
-
1
0.1 µm Prefiltration I
Removes large particulates and protein aggregates; protects the first 0.04 µm cartridge.
-
2
0.04 µm Final filtration I
First 0.04 µm pass; retains sub-micron particulates and microaggregates that pass a 0.22 µm filter, including mycoplasma-sized particles (0.2–0.3 µm).
-
3
0.1 µm Prefiltration II
Second dedicated prefilter, protecting the second 0.04 µm cartridge from breakthrough particulate.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter ahead of aseptic fill in an ISO Class 5 laminar-flow workstation.
Performance vs. conventional media
Four sequential stages reaching 0.04 µm deliver approximately 5× cleaner media by particulate count compared to single-pass 0.22 µm filtration.
