General Maintenance

ultramicroPump requires minimal maintenance; regular laboratory cleaning will 
keep this instrument in optimum operating condition. 

do not apply solvents or oils to any part of the ultramicroPump.

this instrument is 

not autoclavable

.

do not disassemble—there are no serviceable parts inside either the umPii or the 
micro 4 controller.

Always hold ultramicroPump by the main body or mounting bar. do not swing or 
carry the ultramicroPump by its cable.

Storage:

store the umPii in a sealed plastic zip bag to prevent dust from accumulating on 
the drive screw. excessive dust can cause jams and inadvertent stops.

use of gas-tight syringes on the umPii is not recommended for syringes above 
250 µl as this can damage the motor. Please use liquid-tight syringes for 
applications that require volumes greater than 250 µl.

Troubleshooting

Problem:

 the instrument motor makes noise but the plunger button does not travel.

Check:

 look for a loose connector at the rear of the micro4, make sure the umPii 

plug is firmly seated. the gray plastic plug should be a flush fit with the connector 
on the controller. Verify that the pins in the connector are not damaged.

Check: 

test the pump in another channel, with the same program parameters.

Instrument Overtravel 

if the plunger button has traveled to the extreme edge of the pump and has 
jammed, try the following procedure to free the plunger button:

Place the pump so that the syringe would be pointing to the right (no syringe 
should be in the pump). Program the micro4 to syringe style F (or larger to H), 
program in about 2000 to 5000 nl in the volume and program in a rate of 2000 or 
greater (there are internal limits). Press and hold the right or left arrow key for the
