Heathrow Scientific vortexer Manual De Instrucciones página 7

The speed control dial, located in the lower center of the
front panel, has 4-position adjustability (OFF, 1000, 2000,
and 3000rpm). Vortexing speed increases at pre-set rates
to a maximum of 3,000rpm as the knob is turned to the
positions clockwise. Before turning on the Vortexer, set the
speed dial to OFF position (rotate counter-clockwise until
the knob stops). To begin operation, move the power
switch to either the Intermittent TOUCH or ON position
and turn the speed control to the desired setting. If the
power switch is in the ON position, the mixing head will
begin moving immediately. If the power switch is in the
Intermittent TOUCH position, operation will begin when
the 4-speed dial is set to 3000rpm and an object (test
I - Intermittent - Top position
tube) is placed in the center of the mixing head, held at the
II - Continuous - Bottom position
top of the test tube, and moderate pressure is applied to
push down the mixing head. Mixing will cease when the
object is removed and pressure is released.
Intermittent/touch mode:
Place the 3-position switch in the Top Intermittent
TOUCH position and set the speed control round
marker on the dial face to 3000rpm, turned all the way
to the far right position of the dial. When pressure is
released from the mixing head, operation will stop.
Intermittent operation will begin when a test tube is
pressed down in the center area of the mixing head,
while the tube is held firmly at the top.
Hands free/continuous on mode:
Place the 3-position switch in the ON (bottom) position
and set the speed control to any as described above.
Hands Free mode allows mixing or vortexing of the
tubes or microplate and will continue to run until you
stop the mixer by placing the 3-position switch to the
OFF position.
Note:
If the Vortexer overheats during continuous
use, there is a Temperature Protection Device
internally that will temporarily shut off the device.
Once the device cools down, it will be operational
again. Please set switch to OFF position whenever it
is not in operation.
Attention:
It is recommended to NOT leave the
Vortexer unattended while in operation.
OFF mode:
Always place the 3-position switch to the OFF position
(center) when not in use!
