Introduction

Currently, the majority of items requiring daily sterilization in hospitals are transported to the Central Sterile Supply Department (CSSD) for batch processing and subsequent distribution. However, certain departments cannot afford extended turnaround times, as this would disrupt their standard clinical workflows. Such departments frequently include Dental Clinics, Operating Rooms (OR), and Ophthalmology.

To maximize operational efficiency, these high-turnover departments often establish localized sterilization rooms equipped with their own benchtop sterilizers. Benchtop autoclaves are favored for their ease of installation and user-friendly operation, while still delivering the exact same sterilization efficacy as the large-scale steam sterilizers found in the CSSD.

So, how do you correctly select the appropriate benchtop sterilizer for your specific department or laboratory? Let our technical experts guide you through the process.

Classification of Benchtop Sterilizers

Benchtop autoclaves are generally classified into three distinct categories based on their air-removal mechanisms and load capabilities: Class B, Class S, and Class N.

Technical Note: The efficacy of cold air removal directly dictates the overall sterilization performance. Complete steam penetration is only possible when cold air is fully evacuated. The better the air removal, the more reliable the sterilization.

Selection Guide for Benchtop Sterilizers

Benchtop sterilizers are standard equipment in specific medical and clinical environments, most commonly: general hospital dental departments, operating rooms, ophthalmology departments, private dental clinics, and cosmetic surgery hospitals.

When selecting a unit for your facility, follow these two fundamental criteria:

• Determine the Type based on the Load: Analyze the instruments you are sterilizing. If you process hollow instruments (like dental handpieces), porous materials, or wrapped pouches, you must choose a Class B autoclave. If you only process solid, unwrapped metal tools, a Class N may suffice.
• Determine the Capacity based on Load Volume: Calculate your daily throughput. Select the chamber volume (e.g., 18L, 23L) that accommodates your peak processing times without overloading the chamber, which compromises steam circulation.

By assessing both the complexity of your instruments and your daily volume, you can accurately pinpoint the exact sterilizer model required for your workflow.

Critical Precautions & Operating Guidelines

• Installation: The equipment is designed for plug-and-play operation. Simply place it on a stable, horizontal surface. It requires no external water piping or pneumatic air lines.
• Material Compatibility: Sterilizers are exclusively intended for medical instruments and materials that can withstand high temperatures and high humidity. Do not use steam sterilizers for oils (such as Vaseline) or powder-based substances!
• Liquid Sterilization: If you must sterilize liquid media, never place them in completely sealed containers. The containers must remain partially open or well-ventilated to prevent bursting due to pressure expansion.
• Corrosion Warning: Chloride ions are highly corrosive to stainless steel chambers. If you are sterilizing items that contain or have been exposed to chloride ions (e.g., saline solutions), you must thoroughly rinse the interior walls of the sterilization chamber with purified water daily to prevent permanent pitting and corrosion.
