EO ethylene oxide sterilization indicator sticker/card/tape
The principle of EO ethylene oxide sterilization purple to blue indicator label is that it undergoes alkylation reaction with thiol groups (- SH), amino groups (- NH2), hydroxyl groups (- OH), carboxyl groups (- COOH) on protein molecules, as well as amino groups (- NH -) on nucleic acid molecules, causing the protein to lose reactive groups, hindering the normal biochemical reaction and metabolism of the protein and leading to microbial death, thereby achieving sterilization effect.
When using ethylene oxide sterilization gas for sterilization, the temperature, humidity, concentration of sterilization gas, and sterilization time inside the sterilization cabinet are important parameters that affect the sterilization effect. Due to the potential carcinogenicity, mutagenicity, and acute toxicity of ethylene oxide, it is necessary to closely monitor the atmospheric concentration, chamber temperature and humidity, pressure, ethylene oxide gas concentration, and sterilization time during the sterilization process for the safety of personnel. The sterilization effect is usually monitored using biological EO ethylene oxide sterilization indicator labels. The control of sterilizers is somewhat difficult, and the entire sterilization process should be carried out under the supervision of skilled technicians. After sterilization treatment, filtered sterile air should be introduced and undergo a vacuum air circulation process to safely remove residual ethylene oxide.
Suitable for hospitals, pharmaceuticals, food, health products, beverages, hygiene and epidemic prevention, medical equipment manufacturers, and sterilization service institutions to sterilize with ethylene oxide. It is used to indicate whether the sterilization package has undergone ethylene oxide sterilization treatment, and also to test and judge the effectiveness of ethylene oxide sterilization.
Steam sterilization instruction label/card/tape
Coated with color changing ink as a sterilization indicator, back coated with pressure-sensitive adhesive release paper, the label is printed with thermosensitive chemical material, which can be used inside the packaging of the item or attached to the surface of the sterilization package. Under the required sterilization conditions, the indicator color code changes from yellow to black, and the color after sterilization is not easy to fade
Instructions for use:
1. Remove the steam ethane sterilization indicator label from the backing paper and directly stick it to the surface of the sterilized item package. Gently press the label to enhance its sealing effect, and then place it in the steam sterilization pot for sterilization treatment
2. After sterilization, take out the package and observe the color change of the indicator label. If the label changes from yellow to black, it indicates that the package has been sterilized; If the label color remains unchanged, it indicates that the package has not undergone sterilization treatment
Suitable for hospitals, pharmaceuticals, food, health products, beverages, hygiene and epidemic prevention, medical device manufacturers, and sterilization service institutions to perform pressure steam sterilization, used to indicate whether the sterilization package has undergone pressure steam sterilization treatment, and also used for steam sterilization indicator effect testing and judgment
Sterilization instruction label
Sterilization indicator label is a special label used to monitor and indicate whether an item has undergone sterilization treatment. It is usually made of corrugated paper or label paper as the substrate, coated with color changing ink as a sterilization indicator, and back coated with pressure-sensitive adhesive. Under the standard conditions of pressure steam sterilization treatment temperature, temperature duration, and steam saturation, the indicator color block of the sterilization indicator label will change color, such as from light yellow to black, to intuitively reflect whether the sterilization result is qualified
The main uses of sterilization indicator labels include:
- Indicate whether the item package has undergone pressure steam sterilization process
- If the discoloration is uneven or incomplete, it may indicate that the package has not undergone sterilization treatment that meets the conditions
- Sterilization information can be recorded, such as the operator, sterilization expiration date, package item name, pot, etc
There are various types of sterilization indicator labels, including single label, roll label, traceable label, etc., which are suitable for different sterilization needs and scenarios. In addition, with the continuous development of medical technology, the performance and types of sterilization indicator labels are also constantly updated and improved to meet a wider range of sterilization monitoring needs
