Hi all,I was trying to do some flow visualization experiments using PIV on a
microchannel made out of PDMS. I am hexane as the fluid to pass through the
microchannel and I found that hexane doesn't like the microchannel made out of
PDMS. So, I put a piece of the channel in hexane and left it overnight to see
that the PDMS piece had swollen to almost twice its original size. I am now
looking for other ways of making microchannel. One idea that my advisor gave me
was to arrange very fine glass chip on left and right side of a glass slide and
glue them with a substance which glues only under UV source. By arranging the
glass chips on the left and right end of the the glass slide, I get a channel
formed at the center. Now, I cover it with another channel and hence have a
crude microchannel. I use tubing for the inlet and outlet of the microchannel.
With this background, I have two questions for which I need suggestions. 1) Is
there any websource or literature as to how to make the channels using these
glass chips?2)How to I place the inlet and outlet tubing to this microchannel.
Thanks very much in advance, Vishwa
