Engineered where standard media fails
Conventional 0.22 µm–filtered RPMI passes mycoplasma-sized organisms and subvisible particulates that accumulate in microchannel geometries and confound immune cell assays. FluxMPS™ is built to a finer standard.
Microchannel-safe purity
0.04 µm final filtration with USP <788> Method 1 (light obscuration) particulate compliance — suited to suspension immune cell OoC and flow cytometry workflows.
Complete metabolic profile
High Glucose (4500 mg/L), L-Glutamine (300 mg/L), and Sodium Pyruvate (110 mg/L) are all present as standard, supporting a full range of glycolytic and oxidative metabolic assays.
Ultrapure-grade water
Formulated with Type 1 water (18.2 MΩ·cm) — low trace-metal and organic-carbon (TOC) background supports consistent formulation quality lot to lot.
Low background for imaging
Quadruple-stage filtration reduces particulate baseline relative to 0.22 µm media, supporting confocal microscopy and biosensor readouts where subvisible particulates raise background signal. Contains phenol red; not recommended for red/PE-channel fluorescence work.
Rich, stable nutrient profile
RPMI 1640’s balanced amino acid and vitamin profile, plus reduced glutathione (1.0 mg/L), supports demanding lymphocyte, hematopoietic, and cancer cell line culture.
Customization on demand
pH, glucose concentration, salts, HEPES, and nutrient composition available on request — contact support@diagnocine.com.
Quadruple-stage filtration system
Four serial filtration stages — two dedicated 0.1 µm/0.04 µm prefilter-and-final-filter pairs in series — reach a validated 0.04 µm final pore size. Each 0.04 µm final filter is protected by its own dedicated 0.1 µm prefilter, giving full redundancy across the train.
-
1
0.1 µm Prefiltration I
Removes large particulate, cell debris, and protein aggregates; protects the first 0.04 µm cartridge.
-
2
0.04 µm Final filtration I
First 0.04 µm pass; retains mycoplasma-sized organisms (0.2–0.3 µm) and sub-micron particulates that pass a standard 0.22 µm filter.
-
3
0.1 µm Prefiltration II
Second dedicated prefilter, protecting the second 0.04 µm cartridge.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill in a validated ISO Class 5 (Class 100) environment.
Purity architecture 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.
