FluxMPS™ Hank's Balanced Salt Solution w/o Calcium, Magnesium and Phenol Red: 1X
DCP-HBSS-CMR1X is an MPS-grade Hank's Balanced Salt Solution (HBSS) formulated without Calcium Chloride, Magnesium Sulfate, Magnesium Chloride, or Phenol Red, delivering precise pH 7.4 and a defined ionic profile for calcium/magnesium-sensitive protocols. Quadruple-stage 0.1 micron and 0.04 micron membrane filtration produces an ultra-clean, microchannel-safe buffer suited to organ-on-a-chip, tissue-on-a-chip, and microfluidic workflows. Every lot is manufactured under ISO 13485:2016-certified quality systems using ultrapure Type 1 water.

Engineered where standard buffers fail
Conventional 0.22 micron-filtered balanced salt solutions can carry subvisible particulates, accumulate in microchannels, and drift in pH or ionic composition — all of which introduce noise into sensitive cell-based assays. FluxMPS™ DCP-HBSS-CMR1X is built to remove those failure modes at the source.
Microchannel-safe purity
Quadruple-stage 0.1 µm and 0.04 µm membrane filtration reduces particulate load beyond a single-pass 0.22 µm filter, protecting narrow microfluidic channels and valves.
Precise, stable pH
Formulated to pH 7.4 without Calcium Chloride, Magnesium Sulfate, or Magnesium Chloride, minimizing cell aggregation while preserving physiological ionic balance.
Ultrapure-grade water
Manufactured with ultrapure Type 1 water (18.2 MΩ·cm) per USP <85>, eliminating trace contaminants that can confound downstream assays.
Low background for imaging & assays
Phenol red-free formulation eliminates optical interference in fluorescence microscopy, flow cytometry, confocal imaging, and cloning efficiency assays.
Defined, traceable composition
Every inorganic salt and glucose component is lot-released against the composition table below, with calcium and magnesium omitted to prevent unwanted cell clumping.
Customization on demand
pH, concentrations, and the addition of chemicals, compounds, proteins, or supplements can be adjusted to your protocol — contact support@diagnocine.com.
Quadruple-stage filtration system
DCP-HBSS-CMR1X is filtered through a 0.1 micron membrane twice and a 0.04 micron membrane twice, delivering the "world's cleanest buffer" purity claim for cell and molecular biology experiments.
-
1
0.1 µm Pre-Filtration I
Removes large particulates and aggregates from the raw HBSS formulation, extending the service life of the downstream 0.04 µm membranes.
-
2
0.04 µm Pre-Filtration II
Retains fine particulates and bioburden ahead of sterile fill, which is important since the smallest mycoplasma species measure approximately 0.2 microns.
-
3
0.1 µm Sterile-Filtration I
A second 0.1 micron pass provides redundant particulate and bioburden control ahead of final polishing.
-
4
0.04 µm Sterile-Filtration II — Final Polish
A second 0.04 micron pass delivers the final polish, produced under aseptic fill conditions to help prevent mycoplasma contamination.
Performance vs. conventional buffer
Sequential 0.1 micron and 0.04 micron filtration, each applied twice, removes finer particulates than the single 0.22 micron pass used in conventional balanced salt solutions, supporting cleaner microfluidic channels and reduced risk of mycoplasma carryover.

Where DCP-HBSS-CMR1X performs
Formulated without calcium, magnesium, or phenol red, this HBSS supports cell washing prior to dissociation, transport of cell and tissue samples, cell counting and dilution procedures, suspension cultures requiring reduced adhesion, and experiments sensitive to phenol red.
Automated Bioreactors & Robotics
For automated bioreactor and robotic liquid-handling systems, an optional 0.01 µm (10 nm) ultra-filtered variant of this buffer is available to further protect sensitive valves and sensors during continuous, unattended operation.
- Total Particulate Exclusion: sub-10 nm filtration removes particulates that a standard 0.1/0.04 µm stack can pass
- Valve & Sensor Protection: reduces fouling risk in automated dosing and perfusion hardware
- Extended Perfusion Stability: supports longer unattended run times without line clogging
Inquiry Required: the 0.01 µm ultra-filtered grade is produced to order — contact support@diagnocine.com to request this configuration.
Micro Physiological System (MPS) & Chip
Calcium/magnesium-free, phenol red-free HBSS for perfusion of organ-on-a-chip and tissue-on-a-chip devices.
Wash, Dilution & Reconstitution
Used for cell washing prior to dissociation and for cell counting and dilution procedures without calcium- or magnesium-driven clumping.
iPSC-Derived Model Handling
Low-aggregation buffer chemistry supports handling of iPSC-derived cell suspensions during passaging and dissociation.
Endothelial & Primary Cell Perfusion
Suited to suspension cultures requiring reduced adhesion in endothelial and primary cell perfusion protocols.
ELISA, Blotting & Blocking
Phenol red-free formulation avoids optical interference in colorimetric and chemiluminescent immunoassay workflows.
