Environmentally Controlled Benchtop
5-in-1 Refrigerator / Incubator /
Rotator / Rocker / Stirrer
The Enviro-Genie is a Refrigerator / Incubator / Rotator / Rocker / Stirrer for the study of micro­organisms and tissue cell growth under strictly controlled conditions of temperature and agitation. Designed to provide the security of precise temperature control and uniformity for demanding incubation/refrigeration applications without taking up a great deal of space. It performs membrane­based assays/washings and hybridizations more efficiently. Chamber air is gently and continuously circulating at a rate that ensures the temperature consistency and uniformity of all test samples. Shatter resistant viewing window allows for inspection of samples without affecting the chamber environment.
Microprocessor control easily achieves desired rotating, rocking, and stirring speed; temperature; and time; all of which are shown on a large, easy to read display for accurate reproducible conditions. Visible and audible alarms for both temperature and time.
FEATURES:
• 4C to 75C precise temperature range
• Thermo-electric (Peltier) refrigeration & heating – no compressor
• Microprocessor controls allow for accurate, reproducible conditions
Economical, space saving, and secure

BUTTON FUNCTIONS
UP and DOWN buttons are used for:
• Moving through the menu
• Changing parameter value

DISPLAY CONTENTS
Power on the Enviro-Genie (front rocker switch below the control panel). The display will show the following:
After 5 seconds the display will show:
LINE 1 PARAMETERS
MIXER MODES
The Enviro-Genie has 4 Mixer Modes.
STIRRER STIRRER/REV ROTATE/ROCK OFF (Environmental Chamber - no mixing)
REV. TIME
Displayed only when the Mixer Mode is STIRRER/REV and programs the reverse stirring time in seconds.
SPEED STIRRER or STIRRER/REV MODE: display
shows XXX revolutions per minute. ROTATE/ROCK MODE: display shows XX/XX – the first set of values are for Rotate and the second set for Rock. OFF: display is blank.
4
LINE 2 PARAMETERS
MEAS: display shows XX.X - the current
temperature in the environmental chamber.
LINE 3 PARAMETERS
SET: display shows XX.X – the desired
temperature in the environmental chamber. ALARM: display shows ±1°C thru ±9°C or NO.
Alarm will sound if the chamber temperature deviates from your set temperature by the tolerance selected or will not sound if the alarm is disabled (NO).
LINE 4 PARAMETERS
TIME: display shows XX.XX.XX – the desired time
in hours, minutes, seconds – counts down when cycle is started pressing ON/OFF button.
TIMER MODES
The Enviro-Genie has 4 Timer Modes: OFF – expiration of time does not stop the mixer
function or temperature regulation. MIXER ONLY - expiration of time stops the mixer function. TEMP ONLY – expiration of time stops the temperature regulation. MIXER/TEMP – expiration of time stops both the mixer function and temperature regulation.
RANGE OF PARAMETER CHANGE TIME: 00:00 to 99:59 in 1 minute increments.
REV TIME: 1 to 60 seconds in 1 second
increments.
TEMP: 4.0° to 75.0°C in 0.1°C increments. SPEED: STIRRER and STIRRER/REV modes –
1 to 1000 in 1 RPM increments (1-10) and 10 RPM increments (10-1000) . ROTATE/ROCK mode - 1/2 to 35/70 in increments of 1.
MIXER OPERATION The mixer can be turned on by pressing the MIXER
ON/OFF button or the START/STOP button (if
parameters are set). The mixer can be stopped by pressing the MIXER ON/OFF button or, if the time parameter expires,
the unit will turn off automatically. While the mixer is not working, the MIXER ON/OFF button LED will not be lighted.
TEMPERATURE REGULATOR OPERATION
Temperature regulation can be turned ON/OFF by pressing the TEMP ON/OFF button or the START/STOP button. While the temperature regulation is working, the TEMP ON/OFF LED will be GREEN. After the desired temperature has been reached, should the temperature deviate from the range set in the ALARM parameter, the TEMP ON/OFF LED will turn RED and the alarm will sound every 60 seconds. Once the desired temperature is achieved again, the LED will turn GREEN and the alarm will stop.
TIMER OPERATION
Timer can be switched on only by pressing the START/STOP button. While the timer is working, the START/STOP LED is GREEN. After the set time has expired, the START/STOP LED will blink and an alarm will sound every 15 seconds. The time parameter will start to accumulate and represent the amount of time that has expired since the set time elapsed. Pressing the START/STOP button will stop the time from accumulating, the START/STOP LED will turn off and the time display will show the last value set in the time parameter.
CALIBRATION MODE
The Enviro-Genie is electronically factory calibrated and should not need calibration, nor is it recommended. However, should the need arise, the unit may be calibrated, as follows:
In order to calibrate, you will need to make an independent measurement of the chamber temperature. Make sure the thermometer is accurate! Generally speaking, glass thermometers found around the lab will be less accurate than your Enviro-Genie. Good, certified glass or digital thermometers are available from laboratory supply dealers. A thermocouple wire may be passed through the door seal and will not affect performance.
Measure the temperature in the chamber via the lab thermometer, after chamber temperature has
5
been allowed to settle for twenty minutes. Note the difference in temperature between Enviro-Genie displayed temperature and your lab thermometer temperature (ex. Enviro-Genie display reads
37.5C, lab thermometer reads 37.0C; difference is –0.5C). This difference is the calibration value to be entered.
To access the calibration menu, turn the unit OFF. Press and hold the PREVIOUS button while
simultaneously turning the unit ON. The parameters on the display show:
MEAS: XX.X – current temperature in the chamber read by regulatory temperature sensor.
SET: XX.X – calibration temperature setting in °C. OFFSET: X.X – offset from the temperature setting.
The cursor on the display will blink at the value of the SET calibration point. Use the UP and DOWN buttons to adjust your desired SET point. After pressing the OK button, the temperature regulator will turn on and the cursor on the display will blink at the value of the OFFSET point. Wait until the MEAS and SET values are equal (approximately 20 minutes). Compare the temperature read by the unit temperature sensor, MEAS, and the temperature read by the lab thermometer. If the two values are different, adjust the OFFSET, using the UP and DOWN buttons, to make them equal. Wait 20 minutes. Repeat this procedure until the temperature sensor reading equals the lab thermometer reading. Press the ОК button. The display will move to the next menu. Use the UP and DOWN buttons to choose:
SAVE&EXIT, EXIT or RESTORE FACTORY. SAVE&EXIT saves the current value of the set
temperature offset.
EXIT saves the old offset . RESTORE FACTORY resets the set offset.
After pressing the ОК button, the device restarts and goes to a normal working mode.
If the OFFSET is 0 °C , the display (top right) shows FACTORY. If the OFFSET is a value other than 0 °C, the display shows USER.
RANGE OF OFFSET
−2 to +2 °C in 0.1 °C increments.
MIXING MODES MAGNETIC STIRRING
Enviro-Genie comes equipped with two magnetic
stirring platforms, located at the bottom of the chamber. The stirrers are centered on the raised portions of the chamber bottom. The stirrers both operate at the same settings at all times. In general, the highest speeds can only be achieved with smaller stir bars with non-viscous liquids.
If Rotating/Rocking Magnetic Platform is installed remove the platform prior to using magnetic stirrers (see rotating/rocking).
STIR REVERSE
Enabling “Stir Reverse” causes the stir bar to reverse direction at a rate set by the user. The stir bar is gently ramped down in speed to a stop, then ramped up to speed in the opposite direction. Time between reversing is adjustable from 1 to 60 seconds.
NOTE: If a very short stir reversing time is used in conjunction with a very fast stir speed, the
commanded speed may not be attained. The system will not have time to ramp up to speed.
