If your intention is to use it for observing Tyndall cone in your EIS/CS then
any 5mW laser would do...but *NOT* those 1mW promotional giveaway 'toy?'
laser/torchlight ones {we can't purchase the 5mW ones here anymore, unless we
have a note from our mums stating why we want one <nanny government
thing...rolling eyes>}.
In my experience the 1mW lasers are not adequate and *could* mislead you into
believing there are *no* particles present in your solutions because they may
fail to show Tyndall cone {even though there *ARE* particles present in your
solutions}. Go for the better quality and more dependable 5mW lasers.

me in the right direction, I see some on Ebay, but as I say, I have no idea
what to look for.......thanks......Kathy
