Is the MicroPro automatic pipette controlled with an iPad?

Yes, the MicroPro automatic pipette is sold with and operated by an iPad Mini running the MicroPro Controller app. The app is available as a free download in the App Store. Tablet case not included.

Why are MicroPro tips set into a cartridge?

Tips are pre-loaded in a cartridge during manufacturing in order to guarantee perfect seals every time and dramatically reduce the force required to load tips in the lab. Simply lower MicroPro’s head onto a rack of tips with light pressure and MicroPro securely seals all 96 tips.

Does Rainin MicroPro work with 384-well plates?

Yes, flip the “nest” on MicroPro automated pipetting system to the 384 side and work with a 384-well plate by quadrant.

Is it easy to set pipetting depth in 0.2 mm increments on MicroPro, making it easy to lower the head to the same depth repeatedly without being careful?

Yes, with a quick “Find container bottom” step, the MicroPro automated pipetting system senses the bottom of any container. From there, tap the touchscreen to raise the head in 0.2 mm (Fine) or 0.6 mm (Coarse) increments and save the desired depth. Use the same setting over and over with the same type of container, or set different depths based on the liquid being pipetted.

Is MicroPro light?

Yes. MicroPro is the easiest benchtop 96-channel pipettor to move around the lab at just 5.1 kg – a little over 11 lbs.

Is the user manual for MicroPro super technical?

No, the user manual for MicroPro is written to be simple and clear. It’s built right into the tablet interface and is easy to navigate by touch.
