This is a used KD Scientific KDS200 laboratory syringe infusion pump. It can hold up to two syringes.

Our price: $1100


As seen in the pictures, cosmetic condition of this pump is not pristine, but is quite good. It bears a few small cosmetic dings. The display is easy to read, and the membrane keypad appears to be in good condition. There are a few light scratches on the clear plastic of the display, and one small indentation in the plastic there as well. Although we note those cosmetic blemishes here, they do not adversely affect readability of the display. There is also one "shiny" spot between the "8" and "9" keys where the opaque finish on the surface is missing.

Basic functionality has been tested, and appears to be fine. A test was carried out using the method suggested in the technical section of the KDS site, and the pump performed as expected - measured linear travel and delivery time were correct for selected combination of syringe diameter, delivery rate, and delivery volume.
