4. Principle of Operation

Six heating resistors connected to the base plate warm the inner compartment. The temperature of the air in the compartment is constantly monitored at the height of the wells by a thermistor located between the two trays. A circulating fan serves to remove any condensation from the inner lid. The double lid system insulates the plates from changes in ambient temperature.

Four flexible legs support the tray. A microprocessor controls the speed of an orbiting counterweight mechanism that shakes the tray. The user may select any one of 8 speeds ranging from 575 rpm to 1500 rpm.

The following diagram describes the key functions for the instrument. More details on the operation of each feature are provided in Section 8, Operating Procedures .

6. Operating Procedures

1. The ON/OFF switch is located on the back of the instrument.

2. Lift off the smoked acrylic cover. Open the internal cover by pulling back on the metal clip while lifting the front of the clear plastic lid. The covers serve as aerosol guards as well as insulators and should be used at all times.

3. The instrument is designed to hold two standard 96-well microplates or strip trays, round or flat bottom wells.

To properly seat a microplate in the Incubator/Shaker, slide the top edge of the microplate into the silicon bumpers located in the back two corners of the plate holder. By applying pressure to these bumpers with the plate, the bottom edge of the plate should click into place. Press BOTH plates into the bumpers located at the rear corners of the metal frames in the incubation platform. Close the internal cover and replace the outer cover.

6.1 Incubating

To set the incubator temperature, press the SET TEMP key. It will display the previously set temperature. If this is the desired temperature, press ENTER; otherwise, type the desired temperature in Celsius, using the numeric keys, with no more than one place after the decimal point. Press the ENTER key. The instrument will pause to measure and then display the current temperature. (The displayed temperature is corrected to reflect the equilibrated temperature inside a micro-well containing 200µL of water.) Then, either heating will begin or heating will stop depending on the set temperature, until the desired temperature is reached. For faster cooling, open both lids and press the “6” key to turn on the fan. The display will continue to show the incubator temperature, unless another function is selected. A decimal point indicator under the degree symbol reflects the state of the heater. When it is lit the heater is on. When first set, the instrument may over and undershoot the desired temperature but will quickly adjust and hold the temperature constant. When desired temperature is achieved, the heat will pulse on and off to maintain the temperature within +/- 0.5 degrees. The fan may run periodically during heating to prevent water condensation on the internal lid.

To check the temperature when it is not being displayed, press the VIEW TEMP key. The temperature will then be continuously displayed until another function is selected.

If no temperature is entered the unit automatically controls the temperature to 25°C or ambient, whichever is greater.

4-7.

6.3 Timing

To set the timer, press the SET TIME key. The display will show "0.00". Enter one or two digits for the minutes and then a decimal point followed by two digits for the seconds, then press ENTER. If the time has been set since the last power-up, the previously set time will be displayed. If this is the desired time, press ENTER. The maximum time the timer can be set for is 99 minutes and 59 seconds. Press the ENTER key to begin timing.

The display will show a countdown of the time remaining.

When the time has elapsed, the mixing will stop and a beeper will sound. Press the CLEAR key to silence the beeper. Temperature will continue to be maintained after the timing cycle ends.

To turn off the timer while it is running, press the SET TIME key and push CLEAR twice. The display will prompt

"OFF" and the timer will be disabled.

To check the time remaining when it is not being displayed, press the VIEW TIME key. The countdown will be displayed.
