A looooong time ago, when I was running the fly kitchen at Brandeis,
we used a pressure cooker. It was tapped at the top to accept the
house air (not vacuum), and tapped at the bottom to accept a hose with
a pinch clamp. A little skill with the pinch clamp, and a cooker full
could be dispensed rather rapidly, bottles or vials. Be careful,
though, that the dispensing hose is on tightly with a hose clamp. If
it comes off, it's very messy and dangerous (hot fly food everywhere).
If several labs were really interested, we could make a batch
of these. As an improvement, we could use a foot-pedal-operated
electonic hose pinching clamp, and even a timing circuit, for
repeatable volumes. It would be sort of a combination of our
microINJECTOR system, and our PourBoy II sterile media
dispenser, but for "macro-injecting" fly food into bottles.
I would estimate they would cost between $550 and $850,
depending on the quantity we could produce and the exact size
of the pressure cooker we would need to base it on. Anyone interested
or with comments, please send me e-mail.
