Evaporation & Concentration Systems (SpeedVac)

Only if it is built for them, since organic and acidic solvents attack standard seals and corrode an unprotected pump. Solvent resistant systems use compatible seals and a refrigerated trap to capture the vapour. Check that the listed unit is rated for your solvents rather than aqueous duty only. Ask the seller to confirm the solvent compatibility and whether the trap and pump suit organic work.

The cold trap condenses solvent vapour before it reaches the vacuum pump, which protects the pump and recovers solvent. Without an effective trap, vapour degrades the pump oil and the achievable vacuum. Check that a working trap is part of the listing and that it reaches a low enough temperature for your solvents. Ask the seller about the trap and pump condition so the system performs as intended.

Match the rotor format to your typical batch, whether that is microtubes, larger vials or plates. A rotor that fits your consumables and holds your usual number of samples avoids repeat runs. Check which rotors and adapters the listing includes. Give the seller your sample format and numbers so they can confirm the capacity fits.

The heat is gentle and set well below solvent boiling points because the vacuum does most of the work, which protects labile material. Even so, prolonged runs at higher settings can affect very sensitive samples. Choose a system with adjustable heat and confirm the settings suit your samples. The seller can describe the heat control on the listed unit.

You contact the seller directly and can ask for a video of the system pulling vacuum and running a cycle. Because there is no middleman, arranging a demonstration or inspection is straightforward. Sellers are checked before listing, which supports a confident purchase. Agree any inspection arrangements before you complete the SpeedVac purchase.
