The 7900HT instrument features a Peltier-based, interchangeable sample block
module based on the technology established in the GeneAmp
®
PCR System 9700
thermal cycler. The sample block module houses an internal Peltier heating/cooling
unit (Figure 1-4). The sample block module is made of aluminum to provide an
optimal thermal transfer rate between the block and the optical plate or the
TaqMan

The interchangeable sample block module provides:
• Wide temperature range: 4–99.9 °C
•Accuracy: ±0.25°C from 35–99.9 °C
• Heat/cool rate: 1.5 °C per second
• Temperature uniformity: ±0.5 °C (measured 30 sec after the clock starts)
• Long-term stability and high reliability
• Support for multiple consumable formats (see page 1-9)
• Several different modes of operation including 9600 mode and programmable
temperature ramps (see page 3-21)
• Reduced instrument downtime by allowing immediate replacement of the block
(see page 7-6)
• Easy access to the sample block for troubleshooting and maintenance
