Trobot   Motorized heated lid
The TRobot lid is powered by a two step electric motor. First, the lid closes quickly, then the second mechanism carefully interlocks the lid at the front. This ensures that a defined, reproducible pressure is applied. When the lid is closed the electric motor is uncoupled for a long life. The amount of pressure exerted by the lid can be precisely set to one of 15 different positions.

The specialist
For integration in automated environments a thermocycler has to meet very different needs than a bench-top instrument. Since space under the robotic arm is limited, a thermocycler needs a small footprint. To ensure automated workflow, the instrument must have a motorized lid that allows the robotic arm to access the block easily and that is strong enough to reliably seal microplates. All features of the thermocycler have to be controlled via user-friendly software. After cycling, plates need to be easily removed for downstream processing. These specifications were the starting point for the development of the new TRobot thermocycler.

Small footprint
To produce a compact instrument, the TRobot block module has been separated from the controller unit. Thus the controller can be placed outside the workstation. By switching the thermocycler chassis, the airflow direction can be inverted (front to back or vice versa). This minimizes contamination due to air flowing towards a liquid handler or other components.

Reliable uniform cycling
The TRobot thermocycler is available in two different block formats. Taking advantage of the high thermal conductance of silver the Trobot 96 achieves high ramping rates as well as excellent temperature uniformity. The silver block is coated with gold to ensure lasting performance.

The TRobot 384 block is made of Aluminum and achieves perfect fit for 384 well microplates. The 384 well block is coated with a special alloy, which supports easy removal of plates by the motorized lifter.

Trobot   Motorized plate lifter
Removing plates from the block has been one of the major obstacles to thermocycler automation. Due to the tight fit, air between the block and the plate is displaced during cycling causing microplates to stick. This makes it difficult for the plates to be removed by a robotic arm. To solve this problem the Trobot is equipped with four levers that lift the plate from the block as the lid opens. Once lifted the plate can be easily removed by a robotic arm. The levers then return to their initial position allowing a new plate to be positioned.

Communication with the TRobot
All features of the TRobot are controlled via its serial port. A detailed communication protocol is available. Integration in existing software environments (of individual robotic stations) is very easy. In addition to controlling standard features, the TRobot can provide extensive status messages that allow monitoring of all instrument parameters. A software tool for directly operating the TRobot from a Personal Computer is also available.

Internal memory
The TRobot provides an internal memory organized in 10 subdirectories. Programs can be started either by downloading the protocol prior to starting this program. Alternatively, an existing program can be started from the internal memory of the Trobot.

Low power consumption
The TRobot provides economic power management. Due to the low power consumption theTRobot achieves quiet operation and low heat emission. This is especially important when several instruments are used in parallel for high sample throughput.
