Consolidated Sterilizer Systems Double Door Pass-Thru Autoclave / Sterilizer

Pass-thru (double-door) sterilizers may be ordered with optional door interlocks. This electro-mechanical lock on each door minimizes the chance of cross-contamination between contained and uncontained areas by preventing both doors from being opened simultaneously. Additionally, this feature prevents the uncontained side door from opening until a sterilization cycle has successfully completed.

Sustainable Features

Reducing the utility costs and carbon footprint are important consideration for many facility and sustainability stakeholders. Consolidated understands the role autoclaves can play, and we’ve developed these state-of-the-art configurations to significantly reduce water and energy usage for both new and existing sterilizers.

XI™ Controller

Consolidated’s X1™ controllers offer proven reliability, based on an industrial PLC platform programmed specifically for Consolidated’s sterilizers.

XI™ Controller

The X1™ control system include these user-friendly features:

  • Intuitive user interface with modern, easy to view 7″ touchscreen display.
  • Ability to program up to 50 sterilization cycles.
  • Ability to add “favorite cycles” shortcuts for quick access.
  • Ability for managers to prevent users from modifying sterilization parameters on individual cycles.
  • Built from industry-standard, open-source components allowing for easy availability of parts and service.


The X1 controls are equipped with a calendar-based automatic start-up and shut-down feature known as EcoCalendar. This feature helps minimize utility consumption and HVAC load through a software controlled, automatic steam shut-off program. Utilities can be programmed for automatic start-up and shut-down based on time of day and day of the week.

Cloud Access

Maximize laboratory productivity with Consolidated’s cloud-enabled steam autoclaves.

Thanks to a unique partnership with TetraScience, an Internet-of-Things company, Consolidated autoclaves are now able to connect to the internet—allowing scientists, lab managers, and facilities personnel to monitor their autoclaves and download their sterilization data from any internet-ready device. This feature is now included on all Consolidated models manufactured after Sept 2016.* — simply connect the autoclave via Ethernet or Wi-Fi to enjoy the benefits (cloud-based data storage, real time monitoring, and cycle alerts & reminders). In addition to this cloud system, Consolidated autoclaves can be configured with SteriNET® Connex to include remote troubleshooting with live factory support; ideal for facilities that cannot afford any down-time or that are located in remote areas where service assistance is hours or days away.

Cloud Upgrade Available for Existing Autoclaves

Enhance your existing autoclave to harness the Cloud using our Cloud Upgrade Kit. This kit enables a Consolidated sterilizer with an existing Advantage-Series (ADV-PB, ADV-PLUS or ADV-PRO) controller to be upgraded and have all the cloud capabilities as newer-model sterilizers.
