How to sterilize a bottle top dispenser?

Autoclaving is the easiest way to sterilize the Bottle top Dispenser. It can be autoclaved at 121 °C (or 250 °F) and 1 time full (15 psi) with a holding time of at least 15 minutes.

It is recommended to autoclave the equipment after disassembling for deep sterilization. Follow the below steps to autoclave the bottle top dispenser correctly:

1. Perform a standard cleaning of the instrument first.
2. To separate the piston and shaft from the main housing, use the calibration tool to pull the cap outwards to expose the calibration.
3. After unscrewing, take out the shaft.
4. Now autoclave both the assemblies at 121 °C and 15 psi pressure for 15-20 min. Remember that the volume adjustment knob should always be held in the unlocked position during the autoclaving process.
5. Now remove the instrument and its parts from the autoclaving machine and let it cool at room temperature for at least 2 hours before use.
6. Reassemble the parts. The equipment needs to be re-calibrated after each autoclaving process for accurate dispensing.
