Separators & Extraction Systems

The method follows the target and the matrix it sits in. Solid phase extraction suits cleaning up and concentrating analytes from liquids, liquid liquid extraction partitions a target into a solvent, and affinity beads isolate a specific biomolecule. Consider selectivity, throughput and the solvents you can use. Describe your target and matrix to the seller so they can confirm the listed system fits.

The wetted materials and seals decide which solvents a system tolerates without degrading. Aggressive organic solvents attack incompatible plastics and seals over time. Check that the manifold, tubing and any valves suit your chemistry. Ask the seller to confirm the wetted materials so the system stands up to your solvents.

Many solid phase and bead extraction methods run on automated positive pressure or vacuum manifolds that process many samples together. Automation improves recovery consistency and frees the analyst from repetitive steps. Check whether the listed system is manual or automated and how many positions it holds. The seller can describe the throughput and level of automation.

Check the manifold seals, the vacuum or pressure source and any valves or pumps that drive the flow. Worn seals cause uneven flow across cartridges, which hurts recovery consistency. For automated systems, ask about the software and the condition of moving parts. A rig with sound seals and a clear history performs reliably.

Financing is offered on qualifying listings, which helps when an automated extraction platform carries a higher price. Ask the seller when you enquire and they will tell you whether the system qualifies. Spreading the cost keeps capital free for cartridges and consumables. The exact terms vary with the system and the seller offering it.
