Chambers
BMT Sterilab sterilizers are equipped with chambers made entirely of 316L stainless steel for superior durability. The chamber door is made from one solid piece of stainless steel without the need for welding, which ensures the door will not warp over time. Precision machined door brackets for retaining the door on four sides ensures smooth door travel and safe, secure doors. All chamber connections are sanitary clamp type and are sloped to drain. Lubricant- free door gaskets last longer and will eliminate particle shedding into laboratories or clean rooms.

Piping Systems
Depending on the application Sterilab sterilizers can be equipped with bronze and brass or stainless steel piping. Connections can be threaded or sanitary tri-clamp. Industrial grade nonproprietary components are used for reliability and ease in replacement. All piping is insulated and marked either hot or cold for easy identification by maintenance personnel. Water ring vacuum pumps are utilized to ensure repeatable cycles . The seal water is recovered and re-circulated to reduce the overall water consumption by 75%

GMP Ready Design
BMT Sterilizers are designed to meet rigorous requirements needed in Good Laboratory Practices while incorporating the ability to upgrade to any cGMP features needed at the time of order or anytime later in the field should needs change. Flexible options allow each unit to be equipped with the required features for individual projects while allowing the unit to be customized at any time. This lowers the initial investment while ensuring the usability of the sterilizer should requirements change.

Biosafety Levels 3 Applications
Sterilab sterilizers can be equipped with the necessary hardware and software for safe sterilization of bio-hazardous waste. The sterilizer will be equipped with a special fully welded stainless steel bioseal that is connected to the facility wall for an air tight seal. A special clamped gasket design between the facility wall connection and the bioseal allows for vibration and expansion and contraction of the unit without breaking the seal. Special cycles and piping arrangements ensure all contents of the chamber including any condensate is sterilized.

Industrial Grade PLC’S
BMT Sterilab sterilizers are equipped with industrial- grade, Allen Bradley or Siemens PLC based control systems for superior reliability, repeatability of cycles, and serviceability. The programming was developed utilizing the latest GAMP (Good Automated Manufacturing Practices) guidelines for ease in validation and to ensure reliability while allowing for the maximum flexibility for the owner. The system allows for 20 sterilizing cycles to be configured and stored. The operator interface terminal is a large touch screen that is user-friendly and intuitive. Double door units have an operator interface touch screen on both the load and unload sides of the sterilizer. All sterilizer functions are accessed through these touch screens. Displayed messages are in clear text. Multi-level passwords protect from unauthorized access. Each system is supported with a very comprehensive documentation package. The control system can be equipped with different types of printers and\or recorders for data storage on paper. If electronic data storage is desired the control system can be provided with 21 CFR, Part 11 compliancy when connected to a PC or central computer system.

CYCLES

Dry Goods Cycle — Vacuum Drying
The dry goods cycle provides effective sterilization of hard goods, filters, linens, and other porous materials, wrapped goods, and products that are unaffected by vacuum. The load is preconditioned utilizing vacuum and steam pulses. The cycle then advances to heat-up and continues until it reaches the settable exposure temperature of 110°C up to 135°C. Once the exposure temperature set point is reached, the controller counts down the exposure time. After the exposure time is completed, drying begins and can be accomplished by fast exhaust and pulling a deep vacuum to remove moisture.

Dry Goods Cycle — Pulsed Air / Vacuum Drying
This cycle provides effective sterilization of rubber stoppers, hoses, and other materials that are difficult to remove trapped moisture from. The load is preconditioned utilizing vacuum and steam pulses. The cycle then advances to heat-up and continues until it reaches the settable exposure temperature of 110°C up to 135°C. Once the exposure temperature set point is reached, the controller counts down the exposure time. After the exposure time is completed, drying begins and is accomplished by fast exhaust and vacuum and air pulses which are highly effective at removing moisture from the load. To aid drying further the air can be heated.

Solution Cycle — Gravity Air Removal / Ramped Exhaust
The solution cycle with gravity effectively sterilizes liquid products or items in vented or sealed glass containers. The load is preconditioned utilizing steam pulses. The cycle then advances to heat-up and continues until it reaches the settable exposure temperature of 110°C up to 135°C. Once the exposure temperature set point is reached, the controller counts down the exposure time. After the exposure time is completed, exhaust ramping gradually returns liquids to a temperature below boiling.

Solution Cycle — Air Over-Pressure / Jacket Water Cooling
This cycle effectively sterilizes liquid products or items in vented or sealed glass containers. The load is preconditioned utilizing steam pulses. The cycle then advances to heat-up and continues until it reaches the settable exposure temperature of 110°C up to 135°C. After the exposure timer is timed out, cooling of the product is started by injecting air at a pressure
similar to that of the product to avoid breakage of the container. Cold water is introduced to the jacket of the chamber to help cool the product at a faster rate.
