Light Cycler

[R. Jayakumar]

hi.. I have a doubt.  Doesn't DNA adhere to glass or do they use siliconised
glass capillaries for the work.
    1. Why do they use glass capillaries in the first place when it is so
difficult to handle? Can't they make the capillaries out of some other
tougher materials like teflon or something :-)) (considering the exhorbitant
cost of the coffee machine as sussane nicely puts it).
    2. Why is the volume limited to 20 ul.  why can't they use larger size
capillaries
    3. How is this process easy, when we have to buy all the buffers and
other paraphernalia only from some particular companies.
