Steam penetration test “DMA BD”The measuring module BD upgrades the DMA to fulfill the demands of an alternative Bowie-Dick test according to EN  ISO  11140-4. With this module integrated in your LAUTENSCHLÄGER sterilizer the daily Bowie-Dick Test no longer requires the standard test pack or any other alternative indicator system. The DMA determines the extent of steam penetration very precisely. It detects changes and variations long before a critical non-condensable gas concentration in the chamber is reached.

DMA

Patented steam analyzer for sterilization process control and as an electronic steam penetration test – integrated in your steam sterilizer The LAUTENSCHLÄGER DMA detects steam penetration failures caused by leakages, insufficient air removal and non-condensable gases entering the chamber with the steam. Developed for batch and cycle control (Module FW) and as an integrated electronic Bowie-Dick Test (Module BD) to assure highest sterilization safety and optimum economic efficiency.

Failure warning system “DMA FW”The DMA analyzes the composition of the chamber atmosphere during the critical process steps. It works as a failure warning system for cycle control purposes. The DMA is usable as a process challenge device (PCD) according to EN ISO 17665 and it meets the requirements of an Air Detector according to EN 285. Individually calibrated for each sterilizer the DMA reaches excellent accuracy and reproducibility – the reliable, user-friendly and cost-efficient alternative to a classic chemical indicator system. Additional cycle control systems are no longer necessary.

Easy handling and fully automatic documentation As soon as you start a Bowie-Dick test program or a production cycle the sterilizer automatically starts the Bowie-Dick or the cycle control measuring module. The DMA control system evaluates the measurement and prints the measuring result on the cycle documentation protocol – either on the local printer or in combination with an integrated instruments tracking software solution.

Precise evaluation without risk of misinterpretationThe DMA produces clear and unequivocal measuring results: passed or failed – without any subjective interpretation of vague measuring results.

Highly accurate sterilization control with early warning systemAlarm limits are individually adjusted to the sterilizer type and chamber size. Together with its highly precise measuring system and its outstanding reproducibility the DMA is able to detect lowest concentrations of non-condensable gases – far below gas concentrations which would cause a Bowie-Dick Test failure. This enables the DMA to work as an early warning system and to reduce unscheduled sterilizer shut-down periods significantly.

A measuring device for the whole sterilizer lifetime The DMA is designed to work with your sterilizer over its whole lifespan. DMA inspection and re-calibration are part of the yearly sterilizer maintenance service.

Time and cost advantageNo consumables, lowest possible time and effort for the measuring itself and for the evaluation, documentation and archiving of the measuring results – the DMA is the cost-efficient solution for an integrated cycle control system.
