Function and setup
Biometra TAdvanced

A rubber seal on the heated lid forms an encapsulated space around the sample block as
soon as the lid is closed. The closed space serves to improve the temperature uniformity
of the sample block and avoids the formation of condensed water at the final PCR cool-
ing step. Furthermore all blocks are perfectly sealed to prevent condensed water from
penetrating into the Peltier elements underneath the sample block and other parts of
the electronics. The sealing protects the Peltier elements and prolongs the lifetime of
the device.

High Performance Smart Lid
The Biometra TAdvanced heated lid has been optimized to heat twice as fast as with
older models and thus helps to shorten protocol run times. Moreover the heated lid ful-
fills two other important functions: It prevents the formation of condensation at the re-
action tube portion located above the block surface level and it ensures reliable contact
between the reaction tubes and the thermoblock by applying constant pressure. Thanks
to the integrated clutch mechanism, the pressure applied to the reaction tubes is always
the same, regardless of the plasticware height. The combination of the heated lid shape
and the reliable contact pressure ensures even temperature distribution between sam-
ples, thus significantly improving temperature uniformity.
With one press on the front button, the heated lid gently swings open and locks in its
end position. This mechanism ensures that the lid cannot fall down and the heated lid is
out of the radius of action while the user inserts PCR tubes or plates. This prevents any
risk of injury from crushing or hot surfaces.

Display
The Biometra TAdvanced thermal cycler features a 7" state-of-the-art color touchscreen
user interface. The touchscreen is built-in at a flat angle to ensure reflection-free view-
ing and ergonomic programming. For programming PCR protocols the software incorpo-
rates Biometra's proven spreadsheet philosophy and alternatively offers graphical pro-
gramming. One touch of a button leads from the spreadsheet to the alternative graph-
ical programming mode. This makes the creation of new programs or editing existing
programs fast and easy.

User-specific quick start of programs
Many other thermal cyclers offer a so-called "List of latest programs used". In the list of
latest programs used a certain number of PCR programs is collected and offered for
quick start. The list is typically ordered only by date and the user has to search for the
desired program. In contrast the Biometra TAdvanced software creates a user-specific
list and only the latest programs started by the currently logged-in user are offered for
quick start. Even if a lab member does not use the device for a longer time, the infor-
mation on the latest programs started by this user will not get lost.
For maximum convenience the Biometra TAdvanced software additionally features a
program preview. Before the start of a program the protocol steps are summarized in a
clearly arranged table by the program preview tool. The preview therefore provides a
