What You Gain During Process Development

Scale with Less Trial and Error

Moving to a larger vessel changes the magnetic separation step.

Sepmag A allows you to develop the process under controlled conditions and evaluate separation performance before transferring it to manufacturing.

This reduces uncertainty when moving from laboratory protocols to larger batch volumes.

Define the Correct Separation Endpoint

There is no universal magnetic separation time.

Real-time monitoring shows the complete separation curve and allows you to determine when separation is actually complete instead of relying only on visual inspection or an arbitrary waiting time.

Optimize the Process with Data

Compare separation curves while changing:

  • Magnetic bead concentration
  • Bead type or bead lot
  • Buffer composition
  • Sample viscosity
  • Process volume
  • Protocol conditions

This makes protocol optimization measurable rather than subjective.

Protect Recovery During Scale-Up

A process that works at a few milliliters does not automatically deliver the same recovery at hundreds of milliliters.

Controlled separation conditions help minimize bead and target loss as the process moves to larger volumes.

Improve Reproducibility

Establish defined separation conditions that can be repeated across runs, operators and development stages.

Real-time separation data also makes it easier to identify when a run behaves differently from the expected process.

Build a Transferable Process

Characterize the separation step before it reaches manufacturing.

Defined operating conditions, separation curves and objective endpoints provide a stronger basis for process transfer, validation and subsequent GMP production.

Measure Every Separation with Sepmag MONITOR

Sepmag MONITOR provides real-time optical measurement of magnetic bead separation with Sepmag A200ml and A400ml systems.

Instead of recording only how long the sample remained in the separator, you can measure how the beads actually separated.

Use separation curves to:

  • Characterize separation kinetics
  • Define an objective endpoint
  • Compare protocols
  • Compare bead lots
  • Evaluate changes in process conditions
  • Detect abnormal separation behavior
  • Document process development
  • Establish a reference profile for scale-up

Which Sepmag A System Do I Need?

Frequently Asked Questions

When should I move from a small-volume separator to Sepmag A?

Use Sepmag A when you need to move beyond laboratory-scale separation and develop, optimize or characterize the process before manufacturing. Standard Sepmag A bottle configurations cover working volumes from 100 to 400 mL.

What is the difference between Sepmag A200ml and A400ml?

Sepmag A200ml is designed for 100–200 mL working volumes in 250 mL bottles. Sepmag A400ml is designed for 200–400 mL working volumes in 500 mL bottles.

Can Sepmag A be used with laboratory tubes?

Yes. Adaptors allow A200ml and A400ml systems to work with standard 1.5, 2, 15 and 50 mL tubes, making it possible to perform development and troubleshooting at smaller volumes.

How does Sepmag A support scale-up to manufacturing?

Sepmag A allows the magnetic separation step to be characterized using controlled separation conditions, real-time separation curves and objective endpoints. These process parameters provide a stronger basis for transfer to larger Sepmag Q or N manufacturing systems.
