  • Understanding the Differences Between Sanitization and Sterilization

    Understanding the Differences Between Sanitization and Sterilization

    <- Back to Learning Center

    Sanitization and sterilization are two terms that are often used interchangeably, but they actually refer to two different processes. Both are used to clean and disinfect surfaces, but the level of cleanliness achieved is different.

    Sanitization refers to the process of reducing the number of harmful microorganisms on a surface to a safe level, as determined by public health standards. This is typically achieved through the use of chemicals or heat. Sanitized surfaces are considered safe for human contact and use, but some microorganisms may still be present.

    Sterilization, on the other hand, refers to the complete elimination of all microorganisms, including bacteria, viruses, and spores, on a surface. This is typically achieved through the use of chemicals, heat, or radiation. Sterilized surfaces are considered completely free of any living organisms.

    In general, sanitization is used in most everyday cleaning situations, such as cleaning kitchen counters or bathrooms. Sterilization is usually reserved for medical settings, such as operating rooms and laboratories, where a higher level of cleanliness is required to prevent the spread of disease.

    It’s important to note that both sanitization and sterilization require regular maintenance and may not be effective against certain types of microorganisms, such as certain types of bacteria that are resistant to antibiotics.

    In conclusion, sanitization and sterilization are two different processes that are used to clean and disinfect surfaces. Sanitization is used for most everyday cleaning situations, while sterilization is reserved for medical settings where a higher level of cleanliness is required. Both require regular maintenance and may not be effective against certain types of microorganisms.

  • Steam vs Dry Heat vs Chemical Sterilizers – What’s the difference?

    Steam vs Dry Heat vs Chemical Sterilizers – What’s the difference?

    Instrument sterilization is essential to the functioning of many industries. There are several accepted methods that are used to ensure that instruments are sterilized properly. Below we describe 3 of the most common types of sterilizers used in the medical field.

    Regardless of the type of sterilizer you use, the CDC recommends verifying the proper functioning of your instrument using a weekly spore test. Find out more information at www.WoodhouseLabs.com.

    Steam

    Also referred to as an autoclave, steam sterilizers are the most common popular type of sterilizer, due to their versatility and ease of use. There are two common types of autoclave, gravity displacement or pre-vacuum-type, however both rely on a combination of high temperature, high pressure, and time.

    Sterilization times range from 4-30 minutes depending on the temperature and the load type (wrapped vs unwrapped instruments, liquids vs solids, etc). Most autoclaves include a drying cycle which can last from 25-40 minutes. See your manufacturer’s instructions for exact requirements.

    Common manufacturers of steam sterilizers include: 

    • Midmark
    • Harvey (not including the Harvey Chemiclave)
    • Pelton & Crane
    • Renton
    • Validator (Plus)
    • Ultraclave
    • Statim
    • Magnaclave
    • Kavoklave
    • Tuttnauer
    • Ritter

    Dry Heat

    Dry heat sterilizers are often preferred by clinics exclusively sterilizing metal instruments, as these sterilizers do not require steam which may cause corrosion and dulling of metal equipment. Dry heat sterilizers rely on high temperatures and extended time to destroy microorganisms.

    Sterilization times range from 12-150 minutes, depending on temperature and manufacturer’s instructions.

    Common manufacturers of dry heat sterilizers include:

    • Harvey
    • Dentronix
    • Cox
    • Sterident
    • SteriSURE
    • Wayne

    Chemical/Vapor

    Chemical sterilizers are the least common form of sterilization, due to their cost and potential hazards if handled incorrectly. However, when used properly, chemical sterilizers offer the benefits of both steam sterilizers and dry heat sterilizers – resulting in the reduced wear of metal instruments while requiring a shorter sterilization time. Chemical sterilizers use either Ethylene Oxide (EtO), or a combination of alcohol, formaldehyde, ketone, acetone, and water to create a chemical vapor for sterilizing. Like steam sterilizers, they also rely on a combination of high temperature, high pressure, and time.

    Sterilization times typically range from 20-40 minutes, similar to that of steam sterilizers.

    Common manufacturers of chemical sterilizers include:

    • Harvey (Chemiclave)
    • Vapor Steril
