after the air purge.
5.5 Cleaning the Waste Collection Tray
The Waste Collection Tray prevents liquids from splashing or spilling inside the instrument during
the PRIME and FLUSH protocols. The maximum volume capacity of the Waste Collection Tray is
approximately 50ml. Use care when removing the Waste Collection Tray from the Microplate
Sample Tray so that no liquid spills in the inside the instrument.
After each PRIME and FLUSH sequence, discard any fluid in the Waste Collection Tray and rinse
with deionized water.
5.6 Replacing Injector Tips
Injector tip replacements are available from Turner BioSystems. Only injector tips from Turner
BioSystems are fully tested and compatible with the Modulus™ Microplate Reader. See Appendix
C for ordering information.
1. Manually open the instrument door and hold it down with one hand.
2. Gently remove the injector tip assembly from the injector tip holder located
on the Luminescence Module.
3. Twist the white tip valve counterclockwise to release it from the gray tube
fitting. See Figure 18-15 for a picture of the white tip valve.
