Routine Maintenance : ali-Q 2 will require minimal, if any, maintenance, if used as intended. VistaLab recommends
performing routine maintenance and calibration verification at least once a year. Routine maintenance includes:

Cleaning and disinfecting outer body, nozzle cover, nozzle insert and filter

Replacing the membrane filter

Replacing nozzle insert (as-needed)

Aliquot mode calibration verification
Cleaning / Decontaminating :
- Chemical - Occasionally wipe outer housing of the ali-Q 2 and the nozzle cover with a damp
cloth of soapy water or diluted alcohol solutions (e.g. 70% isopropanol).
WARNING!
ALWAYS use protective gloves and eye protection. Avoid the risk of contamination!
- UV Sanitizing - The complete ali-Q 2 unit (outer housing) can withstand typical output (254 nm
wavelength) from UV sterilization lamps.
NOTE: The effects of the UV exposure will likely cause discoloration over time.
Autoclaving:
NEVER AUTOCLAVE ALI-Q 2!!
Only the nozzle cover, nozzle insert and membrane filter can be
detached from the unit and separately autoclaved at:
• 121
°
C (250
°
F); 30 psi (2 bar absolute) with a holding time of at least 15 minutes.
