Optimization test guidelines
About this topic This topic presents the guidelines to consider when planning seal-
quality optimization tests.
Test guidelines When you plan optimization tests, consider the following:
❑ Always run an optimization test for each type of plate material and
plate design. Plates made from the same material but with different
designs can require different sealing parameters.
❑ Always use spare plates in the optimization tests.
❑ Use a new plate for each seal cycle. The characteristics of a plate
can change through repeated seal cycles, therefore changing the
seal results.
❑ Consider the plate content and fluid level in the plate.
❑ Consider the downstream application. For example, plates used in a
thermal cycler will require different sealing parameters than plates
placed in the freezer.
❑ Consider the downstream uses of the plate. For example, plates that
will be sealed one time and discarded can have a more permanent
seal than a plate that will be reused and resealed repeatedly before
being discarded.
❑ Start an optimization test with a low-temperature and short-duration
setting. Adjust the parameters in small increments.
❑ Check the quality of the seal after each seal cycle to determine
which sealing parameters to adjust and whether you need to use an
insert.
❑ Record the optimal sealing parameters.
For seal selection, insert selection, and other optimization test
guidelines, see the PlateLoc Thermal Plate Sealer Seal Selection Guide.
