The data logger EBI 15 is a measuring system for checking steam sterilizers without relying on chemical indicators.

This system can check relevant sterilzation parameters such as vacuum, compensation time, hold time and sterilization temperature. Also, steam penetration analogous to a Bowie & Dick Test can be checked.

The temperature inside a measuring chamber is compared with the outside temperature. If there is a temperature difference, then this is caused by insufficient steam penetration. On the basis of the temperature difference and of the behaviour of both temperature curves, a statement can be made regarding the cause of the insufficient steam penetration (leakage, insufficient vacuum, air injection).

Essentially, here the same method is used as in determining steam penetration with a Helix PCD (process challenge device). Only here, a physical temperature measurement is used instead of a chemical indicator.

Winlog.med or Winlog.med Validation automatically evaluates the temperature difference during readout and presents the results (where applicable) with cause of error.

Required Components

In order to carry out a routine check with the EBI 15 System, the following components are required:

EBI 15 data logger

Interface IF 150 (interface IF 100 and IF 200 can also be used, but then the bottom of the EBI 15 must be screwed off before readout)

Antenna (for transmission from the steri: steri antenna and throughput)

Software Winlog.med
