This
is a Harvard Apparatus model 22 laboratory syringe pump,
Our price: $700
This
is an example of the very popular model 22 laboratory syringe pump from
Harvard
Apparatus.
As
seen in the pictures, cosmetic condition of this pump
is not pristine, but is not ghastly, either. There are a number of
cosmetic
dings and scrapes in the paint. As shown in one of the close-up
pictures, there is one diagonal scratch/gouge on the plastic of the
display; this is not very deep, and does not affect the readability of
the display in use. The display is easy to read, and the membrane
keypad appears to be in good condition as well. A previous owner had
written a name and number on the right-hand side of the pump in
permanent marker, which is still partially visible.
An anchor point has been attached to the cabinet of the pump on the
left-hand side. This anchor swivels, and provides a means by which the
pump could be "locked down" - by use of an appropriate cable
and lock not supplied here - to some hard point in the lab as a
security measure.
Basic
functionality has been tested, and appears to be fine. A test was
carried out, and the pump performed as it should. Actual measured
linear
travel of the pusher block was appropriate for a given combination of
syringe diameter, delivery rate, and delivery time.
