Precision Dispenser (DCI-System)



DCI system is a dispensing unit that utilizes XY motion to dispense measured amount of reagent onto the membrane material or other lateral flow test substrates. The unit is comprised of high quality components which include reliable precision pumps with various dispensing tips (non-contact & contact) as well as an easy-to-use programmable touch screen panel.

2 dispensing lines (stripes) is most common, but the unit can be configured with up to 8 lines of simultaneous dispensing (as per customer’s need) with dispensing of lines, dots, or spray. This versatile tabletop unit is built to last all the while reproducing consistent quality dispensing work.
