Sterilab

Bulk Capacity Laboratory Steam Sterilizers

Sterilab laboratory steam sterilizers are designed to meet the rigorous requirements of Good Laboratory Practices while incorporating the ability to be upgraded to include GMP features at anytime during or after the ordering process. With a range of available chamber sizes and flexible feature options, Sterilab sterilizers can be tailored to an individual project while maintaining the ability to recustomize the unit for future applications. This lowers the initial investment while ensuring the long-term usability of the sterilizer should requirements change.

Bulk capacity sterilizers for high-volume applications and vivarium sterilization

Chamber Construction

BMT USA Sterilab sterilizers are equipped with 316L stainless steel chambers for superior durability. The chamber door is also made from solid plate 316L stainless steel, ensuring the door will not warp over time. Precision machined door brackets for retaining the door on all four sides ensure smooth travel and improved security during the sterilization cycle. All chamber connections are sanitary clamp type and sloped to drain. Lubricant free door gaskets last longer and will eliminate particle shedding into laboratories or clean rooms.

Piping System

Sterilab sterilizers are equipped with stainless steel piping and brass valves. Connections can be threaded or sanitary tri-clamp. Industrial grade, non-proprietary components are used for improved 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 recirculated to reduce the overall water consumption by 75%.

BSL-3 Applications

The Sterilab can be equipped with the necessary hardware and software for the safe sterilization of bio-hazardous waste. When ordered for BSL-3 applications, the sterilizers are equipped with a special fully welded, stainless steel bioseal that is connected to the facility wall, providing an airtight seal. A special clamped gasket is installed between the facility wall connection and the bioseal, allowing for vibration and expansion/contraction of the unit without breaking the seal. Special cycles and piping arrangements ensure all contents of the chamber, including any condensate, are sterilized.

Control System

Industrial-grade Allen Bradley or Siemens PLC control systems provide superior operational reliability and cycle repeatability. The control systems are developed under the latest GAMP (Good Automated Manufacturing Practices) guidelines to ensure system reliability and ease in validation. The control system is also supported with a comprehensive documentation package.

The control system can configure and store 20 sterilizing cycles, which are accessed via a large touch screen operator interface terminal. In double door units, operator interface terminals are mounted on both the load and unload side of the sterilizer. All sterilizer functions are accessed through these screens and are secured by multi-level authentication. If electronic data storage is desired, the control system can be provided with 21 CFR part 11 compliance. Printers and recorders can also be equipped for physical data storage on paper.

Key Features:

Stainless Steel Chamber

The chamber and chamber door are constructed of 100% 316L stainless steel.

GMP-Ready Design

GMP-ready design allows for upgrading the sterilizer on-site to comply with cGMP guidelines if ever required.

Temperature Uniformity

Temperature distribution inside the chamber better than +/- 0.5°C

Energy Efficient

The chamber and all piping are fully insulated to help reduce utility consumption. Equipped water recirculation system reduces water consumption by up to 75%

PLC Controls

Industrial-grade Allen-Bradley or Siemens PLC-based control systems deliver repeatable operation.

Non-Proprietary

Fully constructed with high-grade non-proprietary components for improved reliability and serviceability.

Lubricant-Free Door Gasket

Lubricant-free door gaskets provide greater longevity and eliminate particle shedding into clean rooms.

Automatic Doors

Automatic pneumatic driven precision sliding chamber doors improve safety and convenience during operation.

Sterilab Sterilization Cycles

Sterilab sterilizers can be programmed with any combination of the sterilization cycles described below with configurable parameters for each cycle phase. The programmed cycle recipe is stored in the sterilizer’s control system memory and is recalled and started with the touch of a button on the operator interface. All recipes are also protected from unauthorized changes via a multi-level authentication system.

Dry Goods Cycle - Vacuum Drying

The dry good 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 material where trapped moisture can be difficult to remove. 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 time is completed, drying begins and is accomplished by fast exhaust, 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

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, 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.

Effluent Sterilization Cycle [OPTION]

Sterivap sterilizers can be equipped with optional effluent sterilization cycles suitable for BSL-3 laboratory applications. During effluent sterilization cycles, all steam effluent is captured, filtered, and sterilized prior to being drained out the chamber, ensuring laboratory staff and the environment are further protected from contamination.

Sterilizer Loading Equipment

BMT USA manufactures stainless steel loading equipment in standard or custom designs to accommodate any type of load. Our smaller chamber sizes can be equipped with wire or perforated shelves or loading racks, while large chambers can be equipped with loading carts and transfer trolleys. Large pit-mounted chamber include options for tracks and rub rails that can be designed to work with almost any type of wheel configuration on existing equipment. Carts with drop down wheels are also available for rooms with limited space.
