The Model IN20 is a completely solid state convection chilling/heating incubator for bench top use or use in the field. It is reliable, accurate, compact, and easy to use. The unit is Peltier based for both heating and chilling and has no compressor or CFC's, making it truly energy efficient. The unit is all plastic and translucent for easy sample viewing. The compact design utilizes very little bench space. A convection fan in the unit circulates the air to assure uniform temperature throughout. It measures 8" (20.3 cm) wide by 14" (35.6 cm) deep, and stands 18" (45.7 cm) tall. The unit is run from a manufacturer-supplied table top 12 volt DC power supply that operates at inputs of 90 to 265 volts AC, 50/60 Hz.
The IN20 has simple digital controls and a two line alphanumeric digital display that is backlit for easy reading. The display shows target and actual temperatures and can be used to display the target and actual temperatures and the countdown timer. To set a temperature just push the UP or DOWN ARROW until the display shows the desired target temperature. The unit then will go to that temperature. Calibration is factory set, but calibration is settable by the user to any local standard.
There are POWER and BUFFER lamps on the front panel. The power lamp indicates when the unit is turned on. The buffer lamp flashes when the unit is collecting data. The lamp illuminates constantly when the buffer is full and ready to be downloaded. The buffer can be set to collect data points once a second, once a minute, or once every five minutes to a total of 8110 data points.
The IN20 has an RS232C interface that can be used to record data for monitoring agencies and for controlling the unit via a PC. There is an accessory software package available to set the unit and to plot and print temperature over time.
There are six shelves supplied with each unit. Each shelf will hold two assay plates, even tall form plates, for a total of twelve. In addition, each shelf has a hole pattern on it for centrifuge tubes. Two shelves have 192 holes for 0.2 ml centrifuge tubes aligned to hold PRC tubes in 8- or 12-tube strips. Two shelves have 80 holes for 0.5 ml centrifuge tubes, and two shelves have 60 holes for 1.5 ml centrifuge tubes. All shelves are removable and interchangeable. A stand is provided to hold one shelf when the shelf is removed from the unit to be loaded.
