Re: [DIYbio] Re: Low cost PCR(under development)

Actually, I take back what I said about air not transferring heat to
the sample very quickly. I remember a device a long time ago, I think
it was called the "Indee" or something like that, that used really hot
air and circulated it around the tubes really really fast. I think
the ramp rate was around 8C/s. They basically made up for the poor
thermal conductivity by heating the air up to like 200C and then
bringing it back down as the calculated sample temperature reached the
target temperature. Which made it faster than the peltier devices.
So maybe air wins out in both cost and speed if designed right.
