FluxMPS™ RPMI 1640 Medium (ATCC Modification) w/o Phenol Red: 1X Liquid

Contains L-Glutamine Contains Sodium Bicarbonate Contains HEPES Contains Calcium Contains Magnesium Contains Glucose Contains Sodium Pyruvate Without Phenol Red

FluxMPS™ DCP-RPMIA-R1X is a Microfluidics Suitable cell culture medium engineered for organ-on-a-chip (OoC) and microphysiological system (MPS) platforms. 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.

  • High-glucose (4.5 g/L) RPMI 1640 Medium, ATCC Modification, formulated without phenol red for autofluorescence-sensitive imaging and biosensor assays
  • Contains L-glutamine (300 mg/L), sodium pyruvate (110 mg/L) and 10 mM HEPES (2383 mg/L) for buffered nutrient support
  • Sodium bicarbonate (1.5 g/L) buffering system, consistent with a CO2 incubator requirement near 5% to hold pH 7.4
  • Quadruple-stage filtration (0.1 µm ×2 + 0.04 µm ×2) reaching a 0.04 µm final polish, engineered for microfluidic channel compatibility
  • Endotoxin release specification < 0.05 EU/mL (LAL, USP <85>), tested per manufacturing batch
  • Manufactured under an ISO 13485:2016 quality management system with full lot traceability

Purity Architecture

Quadruple-stage filtration system

Four serial filtration stages, run as two dedicated prefilter-plus-final-filter pairs, reaching a final 0.04 µm polish under ISO Class 5 aseptic conditions.

  1. 1

    0.1 µm Prefiltration I — Large Particulate Removal

    Removes large aggregates and debris; protects the first 0.04 µm cartridge and extends its service life.

  2. 2

    0.04 µm Final filtration I — Mycoplasma-Retentive Barrier

    Retains mycoplasma (0.2–0.3 µm) — a class of contaminant that passes standard 0.22 µm filtration unhindered. First sub-mycoplasma polishing stage.

  3. 3

    0.1 µm Prefiltration II — Second-Pass Redundancy

    A second, dedicated prefilter protecting the second 0.04 µm cartridge from fouling.

  4. 4

    0.04 µm Final filtration II — Polish

    Ultimate polishing filter ahead of ISO Class 5 aseptic fill & finish. Final product QC release gate.

µm Final pore size — sub-mycoplasma polishing
Sterility & Mycoplasma: No growth after 14-day incubation (USP <71>). Mycoplasma risk is controlled by 0.1/0.04 µm mycoplasma-retentive filtration at every stage (not individually tested per lot by USP <63>).
Grade: This product is Microfluidics Suitable, filtered to a 0.04 µm final cut-off. It is not an MPS Grade product — that designation is reserved for the 0.01 µm ultra nano-filtered line, which adds 0.02 µm and 0.01 µm stages after the 0.04 µm polish.

FAQ

Frequently asked questions

Common questions about FluxMPS™ DCP-RPMIA-R1X and its use in OoC and MPS applications.

Yes. DCP-RPMIA-R1X is a Microfluidics Suitable medium engineered for MPS and OoC platforms. The 0.04 µm final filtration reduces microfluidic channel fouling, making it suitable for OoC, ToC, BoC, and LoC applications with sensitivity to particulate contamination.
FluxMPS uses a Quadruple-stage system (0.1 µm ×2 + 0.04 µm ×2), run as two prefilter-plus-final-filter pairs, providing approximately 5× lower particulate counts and a mycoplasma-retentive barrier (0.04 µm) that standard 0.22 µm filtration does not include.
This product uses a specific formulation: [+] 4.5g/L Glucose, [+] L-Glutamine, [+] 1mM Sodium Pyruvate, [+] 1.5g/L Sodium Bicarbonate, [+] 10mM HEPES, [+] Calcium, [+] Magnesium, [-] Phenol Red — formulated without phenol red for assays sensitive to autofluorescence and absorbance interference.
Yes. The sodium bicarbonate buffering system (1.5 g/L NaHCO3) is consistent with a 5% CO2 incubator to maintain the target pH of 7.4. Incubate at 37°C with 5% CO2 unless your protocol specifies otherwise.
Yes. This is a basal medium formulation. Supplement with FBS, serum replacements (e.g., B27, N2), or growth factors as required by your cell type and experimental protocol. When filtering serum-containing supplements, use a 0.2 µm low-protein-binding PES or PVDF filter — never 0.04 µm, which strips serum of the lipoprotein and immunoglobulin fractions it needs to function.
The release specification is < 0.05 EU/mL, verified by the Limulus Amebocyte Lysate (LAL) Bacterial Endotoxin Test (BET) per USP <85> on every manufacturing batch prior to release, not on the individual unit you receive.
Yes. CoA is available per lot upon request at support@diagnocine.com. It includes pH, osmolality, endotoxin, sterility, particulate (USP <788>) data, appearance, and full raw material lot traceability.
