CHEMICAL INDICATORS

Chemical Indicators “Medtest” meet the requirements of a series of standards GOST ISO 11140 and provide a reliable control of steam, air, ozone, ethylenoxide, peroxide (plasma) sterilisation inside the package as well as outside the sterilisation cell.

1st CLASS CHEMICAL INDICATORS ACCORDING TO GOST ISO 11140 (INDICATORS-WITNESSES)

Indicators of the 1st class allow to distinguish sterilised packages from nonsterilised very quickly. In addition, they fulfill other functions as well.

With the help of self-adhesive indicator tapes ИЛГС you can form a laying of sheet sterilisation materials or seal heat sealing packages in the absence of a joint sealer.

A labeler sticks an indicator automatically on the surface of a sterilisation package and prints necessary information.

CHEMICAL INDICATORS FOR STEAM STERILISATION CONTROL

We offer indicators of the 1st,2nd,4th,5th,6th classes according to GOST ISO 11140 for control of most steam sterilisation modes in all types of sterilisers.

A 5th class indicator is sensitive to all critical variables of steam sterilization (temperature, pressure,time, steam saturation similar to a biological indicator, that is why it can be used during different modes of steam sterilization (between 121-134 C)

4th class indicators to be placed inside the packages and sterilisation cell for modes: 134°С/3,5 min, 134°С/4 min, 134°С/5 min, 134°С/7 min, 134°С/10 min, 134°С/18 min, 134°С/20 min, 121°С/15 min, 121°С/20 min, 126°С/10 min, 120°С/90 min, 126°С/60 min, 132°С/45 min, 134°С/27 min,120°С/90 min, 126°С/60 min, 132°С/45 min, 134°С/27 min,120°С/120 min, 126°С/90 min, 132°С/60 min, 134°С/35 min

For 6th class indicators it is typical to have tighter tolerances of critical parameters if compared to the 4th class, thus they are more precise. They are manufactured for the following modes: 134°С/3,5 min, 134°С/4 min, 134°С/5 min, 134°С/7 min, 134°С/10 min, 134°С/18 min, 134°С/20 min, 121°С/15 min, 121°С/20 min.

Indicators ИКПС-Medtest 4th class are placed inside the sterilisation cell to control the modes: 132°С/20 min, 120°С/45 min.

Indicators ИКПС-ВН/01-Medtest 4th class are placed inside the sterilisation cell to control the modes: 132C/20min,120C/45 min.

2nd CLASS INDICATORS FOR CARRYING OUT TEST CYCLES

2nd class indicators imitate articles that are more complicated for saturated steam treatment - full and partial loading. Transition of a chemical indicator to a final stage under these conditions indicates effectiveness of air venting and steam saturation – exactly these 2 processes to a great extent influence effectiveness of steam sterilisation.

4th, 5th CLASS INDICATORS FOR AIR STERILISATION CONTROL

Provide control of the following modes:
180°С/30 min
180°С/45 min
180°С/60 min
200°С/30 min
160°С/150 min
Do not forget that inside the packages and inside the cell there must be placed different indicators.

4th class indicators ИКВС-“Medtest” inside the sterilisation cell

4th class indicators ИКВС-ВН/01 “Medtest” inside the sterilisation cell

5th class indicator can be used to control 3 modes of sterilisation: 180°С/60 min, 200°С/30 min, 160°С/150 min

INDICATORS FOR PEROXIDE (PLASMA), ETHYLENOXIDE, OZONE STERILISATION CONTROL

Are sensitive to the concentration of a sterilising agent, exposure time, temperature, as well as humidity (during ethylenoxide sterilisation).

INDICATORS FOR UV GERMICIDAL IRRADIATION CONTROL

These allow users to control the work of open-type ultraviolet irradiators (an indicator ИКБО-“Medtest”) and germicidal cells (an indicator ИКБК-“Medtest”). With the help of indicators ИКБО- “Medtest” and ИКБК-“Medtest” you can quickly identify when the capacity of a UV-lamp is declining or coming to an end and quickly take necessary steps to increase irradiation time or to change the lamp.
