Sterilab

Custom Laboratory Steam Sterilizers

Overview

Sterilab custom steam sterilizers are designed to meet the rigorous requirements of Good Laboratory Practices while incorporating the ability to be upgraded to include cGMP 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.

Engineered Features

BMT USA offers a range of features that enhance the efficiency, reliability, and serviceability of our sterilizers. Vertical and horizontal precision machined sliding doors are exceptionally smooth and provide a safer environment for operators. Door gaskets that reliably operate without the need for lubrication reduce maintenance and prolong life span. The chamber jacket design utilizes a beam construction that provides a complete envelope around the chamber. PLC-based control systems are intuitive and simple to operate, while providing the necessary sophistication for maximum flexibility and ease of validation.

Control System

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 Steam Source

BMT USA steam generators are designed to provide pure or clean steam to meet the requirements of your sterilization application. The units can be configured as stand-alone units to be used as a central source of steam for multiple units, or directly built into the sterilizer for a fully integrated solution. BMT USA steam generators utilize high grade non-proprietary components and can be electrically heated or heated by plant steam.

Electric Heated Steam

BMT USA electric clean steam generators are equipped with an ASME pressure vessel constructed from 316L stainless steel. The heating elements require three-phase voltage that can be specified at time of order. The units are equipped with an automatic blow-down system that carries impurities to drain. Feed water booster pumps are available when feed water is not available at the required pressure.

Steam-to-Steam

BMT USA steam-to-steam generators utilize plant steam as the heating source to produce clean steam. The tube and shell heat exchanger is made from 316L stainless steel and can be built in single-tube or double-tube configurations. The evaporator utilizes a wetted design that minimizes the temperature difference between the feed water and the heating steam, reducing stress on the evaporator tube sheet.

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.

Sterilizer Accessories & Options

Enhance your sterilizer’s functionality and maximize usable space with a range of sterilizer accessories and options, including 316L stainless steel perforated trays, steam quality sample cooler, printers, paperless videographic recorders, seismic restraint kits, additional operator interfaces, and electropolished chamber and piping finishes.
