Drying Rate; Starting And Stopping A Run - Thermo Scientific Savant Speedvac ISS110 Instruction Manual

2. Gently put a clean Glass Condensation Flask (GCF400) into the refrigerated
chamber. As you lower the flask into the chamber, the CryoCool Fluid rises.
Verify that the final CryoCool liquid level is 10 to 15 mm below the shoulder of
the flask.
3. Immediately wipe clean any CryoCool Fluid that spills onto the rubber seal.
4. Fit the white insulating Flask Seal over the glass flask to secure the flask in the
chamber. Its beveled side faces upward to admit the Flask Cap.
5. Snap the black rubber Flask Cap over the mouth of the glass flask. This pro-
vides easy tubing connection and a vacuum seal while also securing the Glass
Condensation Flask and insulating Flask Seal in the refrigerated chamber.
Rotor Installation. Open the lid of the rotor chamber. Visually align the pin on
the drive shaft with the groove on the bottom of the rotor. Carefully lower the
rotor onto the drive shaft. Rotate the rotor by hand to be sure the pin is lined up
with the groove. Secure the assembly by screwing the retaining knob into the
drive shaft above the rotor. Tighten it firmly but not excessively. Load the rotor
with samples and close the lid.
Always balance rotor loads. An unbalanced rotor causes vibration that will
damage the bearings. Load the rotor symmetrically. There need not be a tube in
each holder, but, you must be sure to evenly balance the rotor by placing an
even number of tubes opposite each other. When using a rotor with aluminum
tube holders, insert all tube holders.
3.1

DRYING RATE

By using the Drying Rate switch, thermal energy can be applied to the
concentrator chamber to counteract the cooling effect of evaporation, maintain
the samples in the liquid state, and accelerate the concentration run.
The DRYING RATE switch selects the desired drying rate:
• LOW maintains the concentrator chamber at ambient temperature.
• MEDIUM maintains the concentrator chamber at approximately 43
• HIGH maintains the concentrator chamber at approximately 65
Select the drying rate according to the nature of your samples.
3.2

STARTING AND STOPPING A RUN

The CONCENTRATOR switch is normally in the OFF position. After loading and
installing the rotor, closing the lid, selecting a DRYING RATE (you may even
pre-heat the samples), press the CONCENTRATOR switch to the ON position to
start the drying run. To stop the run, press the CONCENTRATOR switch to the
OFF position. A run can be stopped at any point and restarted based on your
criterion for sample dryness.
