Somebody can correct me if I am wrong, but think of the platinum kind of the same way as an enzyme catalyst. It simply lowers the energy required to ignite the other reactions. Combustion is just a type of exothermic rxn that requires oxygen and is started by heat, while glycolysis for example does not require heat in that sense it is supplied by ATP and ADH and is thus an oxidation rxn and not necessarily combustion.

Howdy, Recently I have been practicing pipetting small volumes (approx 10 uL). I have been holding the pipette at a 45 degree angle, and I don't normally have the problem with larger volumes. I make sure to press all the way down but still somehow find a way to let the very last bit to come back into the tip upon release. This is also in particular with a single volume pipette. My only thought is that maybe I am pressing the tip too much against the wall? Any help would be appreciated, Nuck Chorris
