Playing with a micropipette puller (Sutter P-97)

Today I tried out the pipette puller I picked up a few months ago. I figured it might be non-functional or need a new filament at least. But it seems to work well, a bargain considering I picked it up for a few hundred pounds and it goes for much more on eBay (and cost a few thousand new I believe).

Anyway, I could successfully pull pipettes as shown in the video above and pictured below. Next I might try some ionic current experiments to characterize the aperture.
