FAQ on the OptiXTRACT Sample Recovery Aid
Can I use the OptiXTRACT Sample Recovery Aid as a fraction collector?
Yes. It’s designed to extract density gradient bands from centrifuge tubes after ultracentrifugation. To collect fractions:
- Position the bottom needle holder at the lowest position.
- Assemble the needle by connecting one end to the adapter and the other end to tubing with a Luer connection.
- Insert the needle into the tube at the desired band location and collect fractions into your collection vessels.
How can I replace the LED?
- Unplug the USB-C cable.
- Remove the LED dimmer by pulling upward.
- Use a 2.5 mm hex key to remove six screws securing the LED board.
- Replace the LED board, reinstall the O-ring, mount, and cover.
- Press the LED dimmer back into place. (See Figures 4.1–4.4 in IFU for visuals.)
What cleaning agents are compatible with the OptiXTRACT Sample Recovery Aid?
