Trident reagent needle guide set of 3

Trident reagent needle guide set of 3

To start, please unscrew the caps from the reagent bottle and gently insert the funnel into the bottle.

Next, insert the needle through the center hole of the guide and securely screw on the bottle cap.

This setup prevents the needle from tipping and ensures it stays in place when the tray is pushed back into position.

Additionally, this method helps to avoid drawing in air and allows for the maximum use of the reagent from the bottle.
