Ovation QS BioNatural Pipette – Adjustable Volume-Set Operator’s Guide
4 - 1
The Ovation pipette requires minimal maintenance. Always store it in its “standing”
position or on the Ovation Pipette Stand (Catalog No. 9058-4003) when not in use.
Clean outer surfaces as needed with a soft cloth dampened with warm water. To
decontaminate outer surfaces, wipe with a 70% aqueous solution of ethanol or
isopropranol, or use a 10% bleach solution followed by water.
WARNING!
Only wipe the volume display with water.
The replaceable nozzle contains an internal aerosol/liquid barrier filter to prevent liquid
from being aspirated into the pipette. Additionally, the nozzle filter offers protection to
internal parts from routine exposure to hazardous liquids and vapors. If this filter
becomes wet, the pipette will not aspirate fluid until a new nozzle is installed or the
nozzle filter is replaced.
Wipe the exterior surface of nozzles with disinfectant or a 10% bleach solution. Care
should be taken not to get the barrier filter inside the nozzle wet, as the pipette will
not aspirate and dispense properly until corrective action is taken.
If the pipette is not aspirating and dispensing properly, it could be caused by
(a) poor fitting alternate source tip, (b) nozzle is loose and needs to be tightened by
turning it clockwise, or (c) a nozzle or nozzle filter needs to be replaced as liquid
has been aspirated into it.
NOTE:
Wear gloves when doing this procedure.
1. Remove ejector sleeve by pulling it away from the pipette body to expose the
nozzle assembly.
2. Place silicone tubing provided on nozzle, and unscrew nozzle in a counter-
clockwise direction. Gently wipe the exposed end of the extension tube with a
slightly dampened, lint-free tissue, then dry it off.
Note: Do not block or dislodge anything at the end of the extension tube.
3. Place silicone tubing on a new nozzle, and screw the nozzle onto the extension
tube in a clockwise direction. Firmly tighten and remove silicone tubing.
4. Slide the ejector sleeve over the nozzle assembly.
5. Push the sleeve firmly into place while using a slight rocking or twisting motion.
