Hey ther, firsttime poster on this forum, but thougth i would browse for ideas.
Me and a associate are putting up a bioassay, where we wan't to subject some larvae for specific temperatureranges for specific amounts of time. We need a programmable device that has a range between +25 to -20 degrees celcious. The twist is, that it needs to be fully programable, both the rate of wich cooling occures, the time it'll stay at a specific temperature, the rate of which re-heating occurs and the stand-by temperature.
A major issue is, that for some of the temperatures, we only wish to subject our specimens to certain temperatures for exactly 60 seconds (+/-5), this is very hard (read. impossible) to control in ordinary climate chambers.
The speciemns we work with, are larve of the common cabbageflea, which overwinters in the stem of cabbage, so the capacity of whatever aparatus you may sugest, needs to be at leas large enough to house a 6 x 15 cm sealed cup containing the samples.
Any ideas would be apreciated, even unconventional ideas
