Professional disinfectants for instruments and medical devices

Disinfectants for instruments and medical devices

In healthcare facilities, clinical laboratories and dental practices, the correct reprocessing and disinfection of reusable instruments are fundamental pillars of controlling healthcare-associated infections. Maintaining a safe environment relies on biocidal products with proven activity, able to destroy the targeted microbial spectrum effectively and in a controlled way while protecting sensitive materials and the fine optics of devices.

On klintensiv.ro you will find a wide range of disinfectants classified as Product Type 2 (TP2), indicated for professional use in surgery, dentistry, endoscopy and gynaecology, and ideal for disinfection protocols by immersion, recirculation or in ultrasonic baths.

Biocidal activity spectrum and European standards

Every product in the Klintensiv portfolio undergoes rigorous testing in accredited laboratories, in line with the European efficacy standards specific to instruments and medical devices:

Bactericidal activity (EN 13727, EN 14561): Destroys the vegetative forms of bacteria on medical and dental instruments, with proven efficacy under dirty conditions and against resistant MDRO strains such as MRSA.
Yeasticidal and fungicidal activity (EN 13624, EN 14562): Completely eliminates yeasts (Candida albicans) and filamentous fungi, preventing cross-contamination in immersion tanks.
Tuberculocidal and mycobactericidal activity (EN 14348, EN 14563): A critical standard for endoscopy and dentistry, ensuring the destruction of Mycobacterium terrae and Mycobacterium avium.
Virucidal activity (EN 14476, EN 17111): Inactivates a broad spectrum of viruses (both enveloped and non-enveloped), providing a barrier against major pathogens such as HBV, HCV, HIV, coronaviruses and others.
Sporicidal activity (EN 17126): Represents high-level disinfection, tested both on general bacterial spores and on highly resistant specific strains such as Clostridioides difficile.

Classification of disinfectants by method of use

To respond flexibly to logistical requirements in the field, the products are organised into two clear subcategories:

Ready-to-use (RTU) products: Liquid solutions and impregnated wet wipes, ideal for disinfecting non-invasive instruments and medical devices or handpieces by spraying, wiping or immersion, with no dilution or rinsing required.
Concentrated products: Liquid formulas, tablets and powders for preparing working solutions according to the dilution tables.

How are instruments and medical devices disinfected correctly?

Instruments and medical devices are correctly disinfected with Klintensiv products using specific methods such as immersion, spraying or wiping, in strict accordance with the directions for use in the biocidal approval. For heat-sensitive devices that require the complete elimination of all microbial forms, including spores, special solutions for cold chemical sterilisation must be used.

What concentration should I use to disinfect instruments?

The concentration needed to disinfect instruments depends directly on the form of the Klintensiv product chosen: ready-to-use (RTU) variants are applied directly, without dilution, while concentrated products must be diluted according to the manufacturer's instructions to ensure microbiological efficacy and protect the materials.

Are the products compatible with instrument materials (stainless steel, plastic, rubber etc.)?

The chemical compatibility of Klintensiv disinfectants with medical instrument materials varies from formula to formula. Before starting decontamination, you must check the full list of compatible materials (stainless steel, plastic, rubber, silicone etc.) specified in the technical data sheet of the chosen product, to prevent damage to the instruments.
