Original Portable Pipet-Aid: Charging the unit for up to 5 hours should completely charge the battery. It is recommended to keep the charger plugged in whenever not in use; this will ensure optimum battery life. All rechargeable batteries have a limited life span. Generally each battery will last approximately 1000 cycles (charges) and then must be replaced.

Pipet-Aid XP/XP2: It should take up to two and a half hours to fully charge the battery. You can still use the Pipet-Aid while it’s plugged into the charger; the charger also seconds as a power supply.

Pipet-Aid XL: It should take up to two and a half hours to fully charge the battery. You can still use the Pipet-Aid while it’s plugged into the charger. The charger also seconds as a power supply.

The Pipet-Aid XP features three speeds on the buttons; (S)low, (M)edium and (F)ast. On the XP
Gravity, the fast speed on the dispense button is replaced with a (G)ravity drain. This feature
allows the user to dispense the liquid by gravity; allowing the liquid to simply fall out of the
pipette when the button is pressed…the motor will not run in this mode.

The short answer is no.

Although the nose piece and its components (with the exception of the
TC Filter) can be autoclaved.

– Wiping the unit with a soft cloth or wipe with isopropyl alcohol is sufficient to clean the
unit. 

– Avoid the use of acetone and other organic solvents which will damage the handle.

– Always disconnect the charger from the unit when cleaning.

– Prevents both over-pipetting and cross-contamination.

– Each layer has a pore size of .8µm; the two layers combined create an optimum barrier to particles as small as .1µm

– Once wetted, it will cease to pass air alerting the user that over pipetting has occurred.

Our unique rubber insert allows the user to use any serological, volumetric and/or blow-out pipettes in either glass, plastic or something similar with sizes ranging from 1 to 100mL.
