How to Sterilize the HVE Tip
It is recommended that the stainless steel tips used on the HVE be heat sterilized between patients using
either sterilizers of the following methods: steam autoclave, or chemical vapor (275ºF [135ºC] maximum
temperature; four minutes at temperature). If you are using disposable HVE tips, be sure to replace
them with new tips between patients.
The table shows the steps for sterilizing the HVE tip.
