Labnet's MultiGene
Gradient Thermal Cycler produces consistent, reliable results
while making gradient technology affordable. This unit is
extremely simple to program, compact in design and built to
perform.
PRECISION THERMAL CONTROL - Rapid heating and cooling of
the precision machined sample block is achieved by six Peltier
modules. Temperature senses across the block feed data to
the microprocessor to control operation of the system and ensure
accuracy and uniformity. Two types of temperature control
are selectable. The first option is block control, which
uses the actual temperature of the block to adjust heating and
cooling input. The second option is tube control, which uses a
sophisticated algorithm program that calculates sample
temperature based on volume and triggers heating and cooling
accordingly to provide quick temperature change in the sample
and minimize over- and undershoot.
EASY PROGRAMMING - Programming the Multi-Gene Gradient
thermal cycler is very intuitive. The large, backlit LCD
displays alphanumeric characters and a graphical representation
of program steps. Simple, on-screen instructions guide the user
through the programming process. The MultiGene Gradient is
provided with common pre-programmed protocols which are easily
edited by navigating to the appropriate parameter with the arrow
keys and entering a new value. A maximum of 99 programs may be
stored in the system memory and organized in public folders or
user folders, which can be password protected.
PROGRAMMING FEATURES - A variety of applications can be
performed with the MultiGene Gradient thermal cycler, from
single temperature soaks to sophisticated multistep programs.
All of these are easily set up. Time or temperature of a cycling
step can be automatically increased or decreased during
successive cycles. This is useful for
"touchdown" applications and extending annealing times
as enzyme is depleted. Programs may also be paused while
running. During operation, actual times and temperatures
are displayed. Estimated run times are automatically calculated
and a log of the last run can be displayed or downloaded to a
PC.
GRADIENT CAPABILITY - The MultiGene Gradient thermal
cycler block can be programmed to operate with uniform
temperature across the block for consistent results, or with a
temperature gradient for protocol optimization. The MultiGene's
gradient is spread horizontally allowing twelve temperatures to
be evaluated simultaneously. To program a gradient, the
high and low temperature are set, and the software automatically
calculates and displays the temperature in each row. A
maximum of 24°C can be set up across the block.
SLIDING, ADJUSTABLE HEATED LID - The heated lid, a
standard feature of the MultiGene Gradient thermal cycler, is
fully adjustable to provide the proper pressure for use with
different height tubes as well as plates. A compression mat is
provided to ensure even pressure when using plates. For optimum
performance, temperature of the lid may be programmed. To ensure
that users never come in contact with the hot surface, the lid
slides back and away from the samples. In addition to
eliminating the risk of burns, this also provides complete
access to samples. The lid can also be flipped up for
cleaning.
