PREPARING THE CONCENTRATOR FOR USE
1. Connect power cord to instrument and plug into appropriate outlet.
The safety lid locking mechanism on SC250 Express will automatically
disengage.
2. Lift the lid and clean the concentrator chamber of any packing material or
foreign items that may be present from shipping.

PREPARATION
• Install the SC250 Express on a clean, dry, stable, level surface within 4 ft.
(1.3 m) of a compatible electrical outlet.
• Place the unit in a convenient location with access to a vacuum source and a
vapor trap*.
• Overhead clearance, equal to 18” (46cm), is required for raising the cover.
WARNING: Before connecting the concentrator to an outlet, make certain that
the voltage, frequency and amperage match the requirements indicated on the
label on the rear of the instrument (120 VAC / 60 Hz, 10 A, 220 VAC / 60 Hz,
5 A; or 230 VAC / 50 Hz, 5A).
*To prevent damage to pump due to vapor exposures from sample solvent and
to extend pump life, a vapor trap that condenses and traps vapors must be
placed in-line between the SpeedVac
®
concentrator and vacuum pump. We offer
integrated universal vacuum systems (integrated vapor trap with vacuum pump)
or component vacuum system (vapor trap plus vacuum pump). See table 1 for
recommended DDA components. Call Thermo for the complete line of vacuum
pumps and refrigerated vapor traps.
