Complete guide: Pupinel "V" roll sterilization indicator
This is a sterilization indicator for pupinel, sold as a roll (impregnated paper tape, white with green stripes, 19mm x 50m). It is applied to the packaging of metal instruments before placing them in the pupinel, and its color changes from green to brown after exposure to dry heat sterilization—providing visual confirmation that the cycle has taken place. It is a basic consumable for tattoo and piercing studios that use pupinel to sterilize metal instruments such as forceps, clamps, and tweezers.
How to use
- Cut a piece from the roll long enough to cover and seal the instrument's packaging.
- Apply the tape onto the packaging of the metal instrument (paper, plastic, metal, textile, or non-woven material) before placing it in the pupinel—the tape's own adhesive sticks directly, without needing additional materials.
- Place the sealed packages into the pupinel and run the dry heat sterilization cycle according to the parameters (temperature and duration) recommended by the manufacturer of your equipment.
- After the cycle is complete, check the tape: it should have changed from green (initial color) to brown. If the color has not changed, do not consider the instruments sterilized.
- Keep the package sealed, with the tape visible, until the moment of using the instrument—the tape remains proof of having passed through the sterilization cycle.
- When opening the package, remove the tape—it peels off easily, without leaving adhesive residue on the surface.
- Store the unused roll in a dry place at room temperature, away from direct light.
Tips from us
- Do not confuse the pupinel indicator with the autoclave indicator—the pupinel sterilizes using dry heat, the autoclave uses steam under pressure, and the two types of tape are not interchangeable.
- Use the indicator for every cycle, not just occasionally—it is part of documenting the studio's sterilization protocol and may be required during a health inspection.
- Visually check the color change every time before using the instruments—do not automatically assume the cycle was correct just because the equipment's program has finished.
- Do not place plastic, rubber, or other materials that can melt or be damaged by dry heat into the pupinel—it is intended for metal instruments that withstand high temperatures.
- Keep a spare roll in stock—as a consumable used for every sterilized package, it is constantly consumed.
- Periodically check that the roll is properly sealed/stored, so that the indicator ink's reaction is not affected by moisture or light before use.
Warning: The color change of the tape confirms that the package has been exposed to a dry heat sterilization cycle, but it does not replace a complete sterilization and hygiene protocol for the studio (equipment maintenance, periodic checks, cleaning of instruments before sterilization). Use the indicator as part of this protocol, not as the sole method of verification, and do not reuse already used tapes or packaging.
Frequently asked questions
What is the difference between the pupinel indicator and the autoclave indicator?▾
The pupinel indicator is formulated for the dry heat used by this type of equipment, while the autoclave indicator reacts to steam under pressure. The two types of tape are not interchangeable—always use the indicator appropriate for the equipment you have, otherwise you risk a false confirmation of sterilization.
What instruments are sterilized in the pupinel?▾
In the pupinel, metal instruments that withstand high temperatures are sterilized—forceps, clamps, tweezers, and other stainless steel instruments. Do not insert plastic, rubber, or other materials that can melt or be damaged by dry heat.
How is the indicator tape practically applied?▾
Cut a piece from the roll and stick it directly onto the instrument packaging, before placing the package in the pupinel—the tape has its own adhesive, no additional tape needed. After the sterilization cycle, check the color change before using the instruments; when opening the package, the tape peels off easily without leaving adhesive marks on the surface.
Does the indicator also work for autoclave?▾
No. It is specially formulated for the dry heat in the pupinel and does not react correctly to the steam under pressure in an autoclave. If you also work with an autoclave, you need the indicator dedicated to that equipment, separate from this one.
How long does a roll last with daily use?▾
It depends on how many packages you sterilize per day, but for a typical consumption of a few centimeters per package, a 50m roll covers a large number of cycles—for a studio with daily sterilizations, a roll typically lasts several months.
How should the indicator tape be properly stored?▾
Keep the roll in a dry place at room temperature, away from direct light, so as not to affect the chemical reaction of the indicator ink before use.
Product description
Steam sterilization indicator, Pupinel Dry heat sterilization indicator, white with green stripes, 19mmx50m, the material being: impregnated paper strip, with ink indicator. Indicator for checking the sterilization in the nursery, in the form of a roll of tape. Sterilization is highlighted by the color change on the indicator from green to brown, after exposure to dry heat sterilization. Sterilization is carried out at 160°C after 40 min. The tapes are versatile and adhere to any type of packaging: paper, plastic, metal, clothes and non-woven material. After sterilization, the tape can be easily removed, without leaving any adhesive on the surface it was applied to. It is suitable to be used as an indicator strip for closed packages that are subjected to dry heat sterilization. The indicator strips serve to seal the packages and ensure evidence of the fact that the packages have been subjected to the sterilization process.
The V-type dry heat sterilizer (pupinel) sterilization indicator, sold per roll, is the dedicated consumable for dry heat sterilization process control in tattoo and piercing studios. Unlike the autoclave indicator, this indicator is specifically formulated to respond to dry heat sterilizer parameters: high temperatures (170-180°C) and extended exposure durations. The indicator tape is applied to metal instrument packages before dry heat sterilizer insertion and visibly changes color after correct dry heat exposure, confirming that the sterilization process has been completed. Dry heat sterilizers are frequently used in tattoo and piercing studios for sterilizing metal instruments that withstand high temperatures, such as forceps, clamps, and other stainless steel instruments. The roll format provides a large number of uses, ensuring long-lasting stock at an advantageous price. The adhesive tape applies easily to various packaging types and provides additional sealing. Using sterilization indicators for every cycle is mandatory according to sanitary protocols and demonstrates the studio's commitment to client safety. The dry heat sterilizer indicator is formulated with chemical substances that react to the extremely high temperatures characteristic of dry heat sterilization (170-180 degrees C over extended durations). This sterilization type is specific to metal instruments that cannot be autoclaved or that benefit from dry heat sterilization. The indicator tape applies simply to instrument packages and provides instant visual confirmation after cycle completion. Consistent indicator use for every sterilization cycle is documented and can be presented to health authorities as proof of hygiene protocol compliance. It is a low-cost consumable providing an essential level of safety.
Frequently Asked Questions What is the difference between pupinel and autoclave indicators? The pupinel indicator is formulated to respond to dry heat (170-180°C), while the autoclave indicator responds to steam under pressure (121-134°C). The two types are not interchangeable - use the correct indicator for each equipment. What instruments are sterilized in a dry heat sterilizer? Metal instruments that withstand very high temperatures are sterilized in dry heat: stainless steel forceps, clamps, tweezers, blades, and other metal instruments. Do not insert plastics, rubber, or materials that can melt. How is the indicator tape applied? Cut a piece of tape and stick it on the instrument package before insertion into the dry heat sterilizer. The tape adheres through its own adhesive. After the cycle, verify the color change before using the instruments. Does the indicator work for autoclaves too? No, the pupinel indicator is exclusively formulated for dry heat and will not react correctly to steam pressure in autoclaves. Using the wrong indicator can generate false results. Use the dedicated indicator for each equipment type. What temperature is needed for color change? The indicator changes color at the specific dry heat sterilization temperature, generally 170-180°C. The color change confirms that the package was exposed to the correct temperature for the duration necessary for sterilization. Is indicator use mandatory for every cycle? Yes, sterilization indicator use for every dry heat cycle is mandatory according to sanitary regulations. This ensures documentation and verification of each sterilized instrument batch. How long does the roll last? Duration depends on sterilization frequency. With 10-15cm usage per package, a standard roll provides hundreds of uses. For a studio with daily sterilizations, the roll lasts several months. How is the indicator stored? Store the roll in a dry place at room temperature, away from direct light and heat sources. Improper storage can alter the chemical substance and generate inaccurate color change results. What if the indicator doesn't change color? If the indicator doesn't change color, the dry heat sterilizer may not have reached correct parameters. Do not use those instruments. Check the sterilizer, temperature settings and duration, and repeat the cycle. Contact service if the problem persists. Can I use the same indicator for both autoclave and pupinel? No, each sterilization type requires its own dedicated indicator. The pupinel indicator responds to dry heat, and the autoclave indicator to steam pressure. Using the wrong indicator will not provide correct sterilization information.
