Frequently Asked Questions

For FAQs about the OT-2 and other products, click here.

Protein purification processes can be conducted with up to 96 samples, with minimal hands-on time.

For more information on timing and throughput, please reference our Automated Ni-NTA bead-based protein purification on the OT-2 liquid handler application note.

The magnets used within our Magnetic Module are N52 Neodymium Magnets.

The Magnetic Module supports protocols with standard or deep 96 well plates with volumes ranging from 10 μL to 2 mL.

For more information on compatible labware and magnetic beads, please reference our Magnetic Module White Paper and our Support team’s labware compatibility article.

It is possible to use multiple modules of the same type on the OT-2. This is true for our Temperature Module, Magnetic Module, and Heater-Shaker Module. For a walkthrough on setting this up for your OT-2 and considerations when using multiple modules, please reference this guide.
