FluxMPS™ MCDB 105 Medium w/o Sodium Bicarbonate: 1X Liquid

FluxMPS™ MCDB 105 Medium w/o Sodium Bicarbonate: 1X Liquid

FluxMPS™ DCP-M105H-B1X is a Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) MCDB 105 formulation engineered for microphysiological systems (MPS), organ-on-a-chip (OoC), and microfluidic tissue models. The quadruple-stage train reaches a 0.04 µm final cut-off, five times finer than the 0.22 µm membranes used for conventional sterile filtration. Formulation: [+] L-Glutamine, [+] Phenol Red, [+] 25 mM HEPES, [+] Calcium, [+] Magnesium, [+] 0.720 g/L Glucose, [+] Sodium Pyruvate | [-] Sodium Bicarbonate. HEPES (25 mM, pKa 7.3 at 37°C) provides CO₂-independent buffering for open-top chip architectures.

Engineered where standard media fails

Conventional 0.22 µm–filtered media passes mycoplasma-sized organisms, subvisible particulates, and micro-aggregates that clog microfluidic channels and interfere with sensor signals. FluxMPS™ addresses these failure modes with four-stage sub-0.04 µm filtration. HEPES buffering removes the CO₂ dependency of bicarbonate-buffered media for open-top chip architectures and atmospheric incubation.

Quadruple-stage filtration system

Four serial filtration stages reach a final 0.04 µm polish under ISO Class 5 aseptic conditions — a level of purity that is difficult to achieve with conventional 0.22 µm filtered media.

1. 1

   0.1 µm Prefiltration I

   Removes large aggregates and particulates; protects the downstream 0.04 µm cartridge and chip geometries.

2. 2

   0.04 µm Final filtration I

   First 0.04 µm mycoplasma-retentive pass; retains sub-micron particulates and microaggregates that pass a 0.22 µm filter.

3. 3

   0.1 µm Prefiltration II

   Second dedicated prefilter, protecting the second 0.04 µm cartridge.

4. 4

   0.04 µm Final filtration II — Polish

   Ultimate 0.04 µm polishing filter; aseptic fill & finish under ISO Class 5 conditions.

Designed for next-generation cell models

FluxMPS™ DCP-M105H-B1X supports demanding platforms from single-channel microfluidic chips to multi-organ body-on-a-chip systems. The integrated 25 mM HEPES buffer makes it particularly suited to open-top microfluidic devices and atmospheric CO₂ environments.

Automated Bioreactors & Robotics

An optional 0.01 µm (10 nm) MPS Grade variant is available on request for automated bioreactor perfusion and robotic liquid handlers.

• Total Particulate Exclusion: 10 nm filtration removes nanoparticulate aggregates
• Valve & Sensor Protection: Reduces micro-fouling of solenoid valves and inline optical sensors
• Extended Perfusion Stability: Consistent nutrient delivery over weeks-long culture

Inquiry Required: Contact support@diagnocine.com for the 0.01 µm MPS Grade variant.
