Flight Clave B – Class B Sterilizer- Autoclave

Brampton- A Class B Sterilizer is a steam sterilizer that uses a vacuum pump to remove air/steam mixtures from the chamber prior to sterilization cycle beginning . This process can remove 99% of the air inside of the chamber before the temperature and pressure increases to it’s necessary parameters. This dynamic air removal provides the necessary conditions to sterilize any load type, including porous or hollow materials, products in pouches, textiles and hollow items like wands, turbines, handpieces and tips.
According to the Public Health of Ontario Dynamic Air Removal Sterilizers (Class B) are the preferred method of sterilization.

What is the difference between a Class B and Class N Sterilizer?

The main difference between a Class B and Class N (Gravity Displacement Sterilizer) is the way the air removed from the chamber prior to sterilization beginning. This essentially determines what type of instruments/material or items can be sterilized adequately in a Class B sterilizer vs a Class N Sterilizer. Class N Sterilizers such as the Midmark M9 and M11, or Tuttanauer EZ9,10 or EZPlus  or Scican Statim 2000, 5000 or our Flight Clave16 or Clave23 machines are considered Class N Sterilizers. These sterilizers use the steam generated from a boiler/steam generator to create a downward displacement, thus pushing out the air in the chamber prior to the sterilization cycle beginning. This method of air removal uses the steam to eliminate the air in the chamber and depending on the method used to expel the air, does not ensure complete removal of air particularly from hollow or porous instruments. A Class B sterilizer on the other hand, with the help of a vacuum pump is able to provide more complete air removal from the most difficult load types before the sterilization cycle begins. With the help of the vacuum pump, the complete air removal from the chamber allows better penetration of steam into difficult load types to ensure the load is 100% properly sterilized before use. This makes the Class B sterilizer the most versatile small, effective, and compact tabletop sterilizer type on the market that is able to efficiently and effectively sterilizer any load type used in the dental, medical, podiatry, chiropodist, tattoo and veterinary markets.

The Clave B Sterilizer differentiates itself from it’s competitors in the field because of it’s ability to provide optimal air removal with a high quality pulsating vacuum pump that removes air pre-sterilization and post sterilization. In addition, the Clave B sterilizer uses a unique steam generator that is able to inject small bursts of steam into the chamber to provide, fast and efficient sterilization.

The Clave B also is also easy to use with a simple interface and very powerful with 5 programmed cycle types and 3 test program types built in to be able to handle any type of materials/loads. The test programs includes your Bowie and Dick Test which should be performed daily, Vacuum Test and Helix Test which can help validate the effectiveness of the device.

How the Flight Clave B – Class B Sterilizer Works?

Step 1- Air Removal: Vacuum pump removes air from the chamber with short pulses. This conditioning process of the chamber for sterilization will remove 99% of the air inside the chamber.

Step 2 – Heating: Once all the air is removed, the steam generator will inject small burst of steam into the chamber until the pressure and temperature reaches the appropriate parameters to start the sterilization time (holding time).

Step 3 – Sterilization: Once the temperature and pressure is reached the system will maintain this temperature and pressure throughout the sterilization time. This is the stage where the sterilization takes place.

Step 4 – Exhaust : The exhaust valve/solenoid valve will open to release the pressure/steam inside the chamber until the pressure is equal to atmospheric pressure.

Step 5 – Drying: After all the air is exhausted after the sterilization cycle. The vacuum pump will again pump out all the moisture and steam from the load until the load is completely dry. The heating elements around the chamber will stay on to allow the water to evaporate into gas and be pumped out by the vacuum.

Step 6- Completion: After the drying is done, the cycle is complete and you can open the door.
