FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES: 1X Liquid

FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES: 1X Liquid

FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES: 1X Liquid is a Microfluidics Suitable, ultra-filtered 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.

• Quadruple-stage nano-filtration: 0.1 µm (Prefiltration I & II) + 0.04 µm (Final filtration I & II), reaching a validated 0.04 µm final pore size
• Endotoxin release specification: < 0.05 EU/mL (USP <85> BET), tested per manufacturing batch
• MEM base formulation; low glucose (1.0 g/L) with 25 mM HEPES; pH 7.4 (USP <791>)
• Prepared with Ultrapure Type 1 water (18.2 MΩ·cm) for trace-metal and organic-carbon control
• ISO Class 5 aseptic fill & finish; manufactured under an ISO 13485:2016 quality management system
• Mycoplasma risk controlled by 0.1 µm mycoplasma-retentive filtration (not tested per lot)
• Custom formulations available — pH, glucose, salts, HEPES, and nutrient composition on request

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 and shortening device lifetimes. FluxMPS™ is built to address these failure modes at the filtration stage.

Quadruple-stage filtration system

FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES: 1X Liquid is processed through a four-stage serial filtration sequence pairing 0.1 µm prefilters with 0.04 µm final filters, reaching a validated 0.04 µm final pore size — well below the 0.2–0.3 µm size range of mycoplasma and below the subvisible particulate load typical of single-pass 0.22 µm filtration.

1. 1

   0.1 µm Prefiltration I

   Removes large particulates, cell debris and protein aggregates; protects the first 0.04 µm final filter cartridge.

2. 2

   0.04 µm Final filtration I

   First 0.04 µm pass; retains sub-micron particulates and microaggregates, including material in the 0.2–0.3 µm mycoplasma size range, that pass through a standard 0.22 µm filter.

3. 3

   0.1 µm Prefiltration II

   Second dedicated prefilter, protecting the second 0.04 µm final filter cartridge from particulate loading.

4. 4

   0.04 µm Final filtration II — Polish

   Ultimate polishing filter; aseptic fill and finish in a validated ISO Class 5 laminar-flow workstation.

Designed for next-generation cell culture platforms

FluxMPS™ Minimum Essential Medium (MEM), Low Glucose & 25mM HEPES: 1X Liquid is validated for organ-on-a-chip, metabolic research, live-cell imaging, and primary cell models where particulate contamination and endotoxin variation are unacceptable.

Automated Bioreactors & Robotics

An optional 0.01 µm (10 nm) ultra-filtered MPS Grade variant is available for automated bioreactor and robotic perfusion systems requiring the ultimate particulate exclusion.

• Total Particulate Exclusion: 10 nm filtration for nanoscale valve and sensor protection
• Valve & Sensor Protection: prevents particulate-induced blockage in precision fluidic systems
• Extended Perfusion Stability: maintains flow rate consistency across multi-week automated runs
