So I'm working on a thermal cycler. And I'm looking to source a heatblock for the tubes. I haven't been able to find a good one for less than $100 most run higher, and I don't want to use a home-made cludgy one with a dremmel as that would be unlikely to produce reliable, repeatable results. So this leads me to a few questions.
1.) Am I missing something? Is there a place to purchase cheap heat-blocks for .2ml eppendorf tubes? Or an alternative solution.
2.) What have others that ran into the problem done? Just ponied up for the expensive heatblock or tinkered with a homemade one til it worked?
3.) If there's no good answer to the first two questions, is this something that the community would find valuable if I worked on a solution for?
