Indicator “PHARMA-TEST” BS-I-120/45 steam internal chemical disposable, class 4 (multivariable) GOST P ISO 11140-1-2009, on a paper-film base with two marks: indicator and reference mark of the color, which should acquire at observance of sterilization parameters. It is intended for operative visual control of compliance with critical parameters of only one sterilization mode indicated on the indicator - sterilization temperature, sterilization holding time and the presence of saturated water vapor inside the products and packages at 120°C/45min. It is used in steam sterilizers with forevacuum or multistage vacuum method of removing air from the sterilization chamber.

It is highly recommended to use the internal indicator “PHARMA-TEST” BS-I-120/45 and the external indicator “PHARMA-TEST” BS-T-120/45 in the same cycle to simultaneously monitor the parameters inside the bag with instruments and the performance of the sterilizer.

Indicators are supplied in A4 sheets and are separated from each other along the perforation line. Indicators are packed in individual packaging with a label (marking) corresponding to the name and type, complete with this instruction and logbook of sterilization parameters F.257/U.

The sticky layer ensures that the indicator is securely fixed at the control point.

- sanitary and epidemiological facilities
- disinfection stations.

The internal indicator BS-I-“PHARMA-TEST” is designed for professional users-personnel of medical institutions, disinfection and sanitary-epidemiological services, as well as other organizations and institutions authorized to carry out sterilization and disinfection activities in the operational visual control of the parameters of regimes and conditions in each cycle of steam sterilization of medical devices, inside stacks, packages, sterilization boxes in steam sterilizers with a forced method of pre-sterilization.

Indicators allow to detect deviations from the regulatory parameters of modes and conditions of steam sterilization caused by:

• presence of air inside sterilizable packages, stacks in sterilization boxes;
• insufficient duration of the air removal phase, lack of tightness (air leakage) of the sterilizer lid connections during the air removal phase (“purging”);
• inhomogeneity of supplied steam parameters or its non-compliance (fluid, dry, superheated) with the set parameters;
• improper sterilizer configuration or loading volume; sterilization mode parameter setting error or failure.

To place and fix the indicator BS-I-“PHARMA-TEST” inside each sterilization package, stack from the back side of the left part of the indicator, freely from the thermal indicator mark, separate a part of the protective paper covering, covering the sticky layer, and fix the indicator inside the sterilized package, stack with an adhesive layer.

When placing sterilization stacks, boxes (bixes) in the sterilization chamber should be guided by the rules:

• sterilization boxes (bixes) are placed in the sterilization chamber perpendicular to the direction of steam flow in the chamber;
• sterilization boxes (bixes) with a large number (size) are placed at the rear wall of the sterilization chamber.
• the distance from the door (lid) of the steam sterilizer to the sterilization box (bix) must be at least 15 cm.

* in accordance with MU No. 287/113 of 30.12.98, the loading rate of sterilization boxes (stacks) for steam sterilizers that do not have vacuumization at the “purge” stage should be reduced by 3 times of the loading rate.
