The control panel features a display that reads from 1 to 100ul (L/min) and can be easily read from the front or back. A cutout in the barrel of the device allows for a syringe to be inserted into the delivery port followed by release of the plunger to initiate delivery. The design of the microisolator has been modified to perform better in clinical diagnostic procedures. A clog-resistant check valve on the delivery port would allow for the use of higher concentrations of liquid-phase substances such as swab samples without a need to use a hose clamp. A flange bolt on the delivery pin allows for secure attachment of a syringe.
