FluxMPS™ RPMI 1640 Medium, High Glucose w/o Sodium Bicarbonate, Phenol Red: 1X Liquid
FluxMPS™ RPMI 1640 Medium, High Glucose w/o Sodium Bicarbonate, Phenol Red: 1X Liquid is a Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) 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. This bicarbonate-free, phenol-red-free, HEPES-free base gives researchers full control of the buffering system for metabolic-flux, imaging, and Seahorse XF workflows.

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 engineered to address these failure modes at the source.
Microchannel-safe purity
0.04 µm final filter retains particles down to sub-mycoplasma size; USP <788> Method 1 (light obscuration) particulate compliance verified per lot.
Total metabolic control
Defined glucose (4500 mg/L), L-glutamine (300 mg/L) and sodium pyruvate (110 mg/L) concentrations support quantitative metabolic flux and Warburg-effect studies referenced to known baseline inputs.
Ultrapure-grade water
Prepared with Type 1 water (18.2 MΩ·cm) meeting ASTM D1193 / ISO 3696 ultrapure standards, with tight control of trace metals and total organic carbon (TOC).
Low background for imaging
Ultra-low particulate baseline supports high-content confocal microscopy, live-cell biosensors, and TEER measurements without particulate interference.
Rich, stable nutrient profile
Micro-batch precision manufacturing locks in amino acid and vitamin concentrations, ensuring lot-to-lot reproducibility critical for long-term perfusion studies.
Customization on demand

Quadruple-stage filtration system
FluxMPS™ RPMI 1640 Medium, High Glucose w/o Sodium Bicarbonate, Phenol Red: 1X Liquid is processed through a four-stage serial filtration sequence — two dedicated prefilter-and-final-filter pairs — reaching a 0.04 µm final cut-off, addressing mycoplasma-sized particulates and subvisible debris that single-pass 0.22 µm filtration cannot.
-
