FluxMPS™ Tris-HCl Buffer, Sterile [1X]
An MPS-grade, quadruple-stage ultra-filtered Tris-HCl buffer built for molecular biology, protein work, and microfluidic / organ-on-a-chip (OoC) applications. Formulated from 1M Tris base and adjusted to a stable pH of 8 ± 0.04 with HCl, it buffers reliably across pH 7.0 to 9.0 without interfering with most biochemical reactions or common divalent ions.

Engineered where standard buffers fail
Conventional single-pass, 0.22 µm-filtered buffers can carry subvisible particulates and residual bioburden that accumulate in narrow microfluidic channels, drift ionic conditions, and add background to sensitive assays. FluxMPS™ Tris-HCl Buffer is built to a tighter standard from the first filtration pass onward.
Microchannel-safe purity
Quadruple-stage 0.1 µm and 0.04 µm membrane filtration, each applied twice, is designed to keep microfluidic and organ-on-a-chip (OoC) channels free of the particulate load that clogs standard single-pass buffers.
Precise, stable pH
Formulated to pH 8 ± 0.04 with buffering capacity spanning pH 7.0 to 9.0, keeping downstream reactions and protein-protein interactions free from abrupt pH shifts.
Ultrapure-grade water
Prepared with Ultrapure Type 1 water (18.2 MΩ·cm), reducing trace contaminants relevant to sensitive molecular and cell-based work.
Low background for sensitive work
Tris-HCl does not significantly interfere with or inhibit most biochemical reactions, enzymes, or common ions such as calcium and magnesium, supporting clean results in electrophoresis and protein purification.
Defined, traceable composition
Made from 1M Tris base adjusted with HCl, with no detectable DNase or RNase activity after 18 hr incubation at room temperature.
Customization on demand
Alternate concentrations, pH values, and additions of chemicals, compounds, proteins, or supplements can be requested for your protocol.
Quadruple-stage filtration system
FluxMPS™ Tris-HCl Buffer, Sterile [1X] is filtered-sterilized with 0.1 µm membrane filtration twice and 0.04 µm membrane filtration twice, in a sterile environment, to help prevent mycoplasma contamination.
-
1
0.1 µm Pre-filtration I
First pass through a 0.1 µm membrane removes large particulates and aggregates, extending the life of downstream filters.
-
2
0.04 µm Pre-filtration II
A 0.04 µm membrane pass retains fine particulates and bioburden ahead of the final sterile-filtration stages.
-
3
0.1 µm Sterile-filtration I
A second 0.1 µm pass provides redundancy against particulate and microbial breakthrough.
-
4
0.04 µm Sterile-filtration II — Final Polish
A second 0.04 µm pass, performed in a sterile environment, delivers the final polish. Mycoplasma organisms can be as small as approximately 0.2 microns, so this final stage is sized well below that threshold to help prevent mycoplasma contamination.
Performance vs. conventional buffer
Sequential 0.1 µm and 0.04 µm filtration, each applied twice, removes finer particulates than a single 0.22 µm pass used in conventional buffer, and is performed in a sterile environment to help prevent mycoplasma contamination.

Where FluxMPS™ Tris-HCl Buffer is used
Tris-HCl buffer is widely used across molecular biology and cell biology workflows, including gel electrophoresis, nucleic acid work, protein extraction/purification, and cell culture media preparation, and it extends naturally into microfluidic and organ-on-a-chip (OoC) systems.
Automated Bioreactors & Robotics
For automated bioreactor and robotic liquid-handling platforms with the tightest particulate tolerances, an optional 0.01 µm (10 nm) ultra-filtered variant of this buffer is available on inquiry.
- Total Particulate Exclusion — supports platforms requiring particulate control beyond the standard quadruple-stage architecture
- Valve & Sensor Protection — helps protect fine-bore valves, sensors, and microfluidic tubing from fouling
- Extended Perfusion Stability — supports longer unattended perfusion runs in automated systems
