BMT Sterilab - Bulk Capacity Laboratory Steam Sterilizers

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.

Custom Loading Equipment

BMT USA manufactures stainless steel loading equipment in standard or custom designs to accommodate loads of any size, shape or weight. Our smaller chamber sizes can be equipped with wire or perforated shelves and loading racks, while larger chambers can be equipped with carts and transfer trolleys.

Large pit-mounted chambers include options for tracks and rub rails that can be designed to work with the wheel configuration of your existing equipment. Carts with drop down wheels are available for rooms with limited space.

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.

• Bioseal
• Custom loading equipment, including carts, trolleys, shelving and trays.

Dry Goods Cycle - Vacuum Drying

Effective sterilization of hard goods, filters, linens, porous materials, wrapped goods, and products that are unaffected by vacuum.

The load is preconditioned with alternating vacuum and steam pulses, then heated to an exposure temperature between 110°C and 135°C. The exposure temperature is maintained for a specified period, after which rapid drying begins with fast exhaust and pulling a deep vacuum.

Dry Goods Cycle - Vacuum Drying with Air Pulses

Effective sterilization of rubber stoppers, hoses, and other material where trapped moisture can be difficult to remove.

The load is preconditioned with alternating vacuum and steam pulses, then heated to an exposure temperature between 110°C and 135°C. The exposure temperature is maintained for a specified period, after which drying begins by fast exhaust, vacuum and air pulses which are highly effective in removing moisture from the load. The air pulses can also be heated to further aid the drying process.

Solution Cycle - Gravity Air Removal with Ramped Exhaust

Sterilization of liquids in vented or sealed glass containers

The load is preconditioned with steam pulses before heating to an exposure temperature between 110°C up to 135°C. The exposure temperature is held for a specified time period followed by a gradual exhaust ramping to cool the load back to ambient temperature.

Solution Cycle - Air Over-Pressure with Jacket Water Cooling

Sterilization of liquids in heat or pressure-sensitive containers

The load is preconditioned with steam pulses, then heated to an exposure temperature between 110°C and 135°C. The exposure temperature is maintained for a specified period, after which the cooling phase begins by injecting air at a pressure equal to that inside the product container to prevent damage or deformation. To accelerate cooling, cold water is introduced into the chamber jacket.

Sterilab sterilizers can be programmed with any combination of dry goods and solution sterilization cycles, with configurable parameters for each cycle phase. The programmed cycle recipes are securely stored in the control system memory and can be effortlessly retrieved and initiated via the touchscreen operator interface. Unauthorized modifications are prevented through a multi-level authentication system, ensuring recipe integrity and operational compliance.
