- Microfluidic‑ready PBS, 1X (Phosphate Buffered Saline), Sterile, 500ml/1000ml/10 Liter, 0.04um filtered
FluxMPS™ Microfluidic-ready PBS, 1X (Phosphate Buffered Saline), Sterile, 500ml/1000ml/10 Liter, 0.04um filtered
An MPS-grade, ready-to-use 1X phosphate buffered saline built for microfluidic and organ-on-a-chip (OoC) workflows. Sterilized by filtering the finished buffer TWICE (2X) through 0.04 micron (40nm) membranes in a controlled cleanroom environment—well beyond the industry-standard single-pass 0.22 µm filtration—to keep micro-scale channels clear and cellular microenvironments pristine. Formulated without calcium (CaCl2) or magnesium (MgCl2) for high-efficiency dissociation and rinsing.

Engineered where standard buffers fail
Conventional 0.22 µm-filtered PBS is designed to stop bacteria, but it can still pass mycoplasma, large viruses, and sub-micron particulate that accumulate in narrow microfluidic channels, drift pH and ionic balance, and elevate background in sensitive assays. FluxMPS™ PBS is built to a tighter purity standard from the ground up.
Microchannel-safe purity
Double-filtered (2X) through 0.04 micron (40nm) membranes in a controlled cleanroom environment, removing sub-micron particulates that a single 0.22 µm pass allows through.
Precise, stable pH
Ready-to-use 1X formulation at pH 7.4, with customization available on request for protocol-specific requirements.
Ultrapure-grade water
Prepared with ASTM 0.05 µS/cm Type 1 Ultrapure Deionized H2O for a clean, low-background base solution.
Low background for imaging & assays
Minimal particulate load supports high-resolution imaging and nano-scale applications where debris interferes with signal.
Defined, traceable composition
Formulated with NaCl, KCl, Na2HPO4, and KH2PO4 at fixed concentrations, without CaCl2 or MgCl2.
Customization on demand

Dual-pass 0.04 micron (40nm) filtration system
Rather than a single pass through a standard 0.22 µm filter, this PBS is sterilized by filtering the finished buffer twice through 0.04 micron (40nm) membranes in a controlled cleanroom environment, targeting particulates, mycoplasma, and large viruses that a coarser single-pass filter can miss.
-
1
0.04 µm Primary Filtration
First pass through a 0.04 micron (40nm) membrane in a controlled cleanroom environment, removing bacteria, mycoplasma-scale organisms, and sub-micron particulates.
-
2
0.04 µm Final Polish Filtration
Second pass through a fresh 0.04 micron (40nm) membrane for redundant, sterilizing-grade purity beyond standard single-pass 0.22 µm processing.
Performance vs. conventional buffer
Double-pass 0.04 micron (40nm) filtration targets particulates, mycoplasma, and large viruses that can pass through a standard single-pass 0.22 µm filter, supporting cleaner fluidic channels in high-resolution imaging and microfluidic applications.
