24-HOUR BIOLOGICAL INDICATOR 25U D_DEVICES
Product description
INDICATORE BIOLOGICO 24 ORE 25U D_DEVICES is a biological indicator designed to monitor the effectiveness of steam sterilization processes in autoclaves operating between 121 C and 135 C. Supplied in a 25-unit format, it supports routine sterilization control in dental and clinical settings, helping verify that the cycle parameters achieve the intended microbial inactivation.
Main features
- For steam sterilization monitoring in autoclaves from 121 C to 135 C.
- Contains Geobacillus stearothermophilus ATCC 7953 spores, selected for high heat resistance to provide reliable control.
- Rapid 24-hour results with stated accuracy of 7%.
- Easy interpretation: culture medium changes from purple to yellow in the presence of bacterial growth.
- Includes a Type 1 chemical indicator that changes from pink to black after steam exposure.
- Compliant with ISO 11138-1, ISO 11138-3, ISO 11138-8 and ISO 11140-1.
Uses and applications
Indicated for routine performance monitoring and validation support of steam sterilization cycles in dental practices and clinical sterilization workflows. Instructions for use: place the biological indicator inside the load to be sterilized, run the autoclave cycle, incubate at 54 C
0 C60 C, and verify the color change to determine the outcome.
Benefits for the professional
- Supports evidence-based quality assurance of autoclave performance and sterilization process control.
- Faster release decisions with 24-hour readout compared to longer incubation approaches.
- Clear pass/fail interpretation via visual color change, helping standardize internal checks.
- Dual control approach (biological indicator plus Type 1 chemical indicator) to strengthen routine monitoring documentation.
- International standards compliance to align with regulated sterilization and infection control requirements.
