Frequently asked questions
FAQ: Instruments
The hygiene cycle of manual instrument preparation ensures that medical products are cleaned, disinfected, sterilised, and documented for release after each use. The following 8 steps form a typical process:
- Preparation and transport
Remove gross contamination immediately after treatment. Collect instruments safely and transport them from the treatment area to the preparation area. - Cleaning and intermediate rinsing
Instruments should be disassembled or placed in a container with a cartridge and lid without air bubbles. Completely cover with an enzymatic cleaning solution, e.g. ID 215.
Typical exposure time: 10–15 minutes, depending on the degree of contamination and according to the manufacturer's instructions.
Then mechanically clean (if necessary, using an ultrasonic bath) and thoroughly rinse with water. - Disinfection and rinsing
Reassemble cleaned instruments and place them without air bubbles in a suitable container, covering completely with a disinfectant solution (e.g. ID 212, ID 212 forte plus or ID 213).
Exposure time according to the manufacturer's instructions, usually 5–10 minutes.
Then rinse thoroughly under running water. Optionally, perform a final rinse with demineralised water to avoid water spots or corrosion. - Drying and functional check
Completely dry instruments with a hygienic, lint-free cloth or with hygienic compressed air.
Conduct a visual inspection for cleanliness, corrosion, material changes, and functionality.
Care for joint instruments if necessary (e.g. oiling). Sort out or repair defective instruments. - Packaging
Select an appropriate sterilisation barrier system (e.g. transparent sterilisation packaging).
Equip sharp or pointed instruments with protective caps.
Fill the sterilisation barrier system to a maximum of about 75% and seal according to the manufacturer's instructions.
Check the seal seam for a continuous, tight structure without air inclusions or channels. - Steam sterilisation
Load the steriliser according to the manufacturer's loading pattern.
Insert the helix test body.
Select an appropriate sterilisation programme.
After the programme ends, check the autoclave protocol and verify the colour change of the helix test strip. - Release and label
Check the sterilisation barrier system for dryness, integrity, and tight seal seam.
Label with sterilisation data.
Conduct documented release for reuse. - Storage
Store sterile instruments dust-free, dry, and in closed cabinets.
When using appropriate sterilisation barrier systems, the storage duration is generally up to 6 months, depending on packaging quality, seal seam, and storage conditions.
The consistent implementation of all steps supports patient safety, infection control, and legal certainty.
Rotating instruments such as drills and burs are sensitive and require careful preparation according to hygiene cycles and manufacturer instructions.
- Immediately after use
Remove coarse residues immediately. - Manual cleaning
Completely cover drills in a suitable drill box with an enzymatic cleaning solution, e.g. ID 215.
Typical exposure time: 10–15 minutes according to the manufacturer's instructions.
Alternatively or additionally, an ultrasonic device may be used. - Intermediate rinsing
Rinse thoroughly with water, re-clean if necessary. - Manual disinfection
Place cleaned drills in a drill box with a suitable disinfectant solution, e.g. ID 220.
Observe exposure time according to the manufacturer's instructions.
Subsequently rinse under running water and dry with a hygienic, lint-free cloth or compressed air. - Visual check
Check for cleanliness, integrity, and cutting performance. - Sterilisation
Sterilise in a steam steriliser according to the manufacturer's instructions. - Documented release
Check and document the sterilisation process. - Contamination-protected storage
Store sterile and dry.
Note: Overheating, excessive pressure, or processing very hard materials can accelerate the wear of diamond or carbide drills.
The exposure time depends on the product used and must be adhered to according to the manufacturer's instructions.
ID 215 (Cleaning)
Typically 10–15 minutes, depending on the degree of soiling.
ID 212 / ID 213 (Disinfection)
Exposure time according to the manufacturer's instructions, usually 5–10 minutes.
Important: The instruments must be completely covered by the solution throughout the entire exposure time. After the time has elapsed, rinse thoroughly with water and allow to dry completely. Adhering to the exposure time supports effective cleaning and disinfection as well as material protection.
Cleaning and disinfection are two consecutive but distinct steps in the instrument hygiene cycle.
Cleaning (e.g. with ID 215)
Dissolves and removes organic residues such as blood, saliva, or tissue.
Ensures visible cleanliness and prepares the instrument for disinfection.
Disinfection (e.g. with ID 212 or ID 213)
Inactivates pathogenic microorganisms on the cleaned instrument.
Reduces the risk of infection prior to subsequent sterilisation.
Key point: Cleaning ensures visible cleanliness, disinfection ensures microbiological safety. Both steps are necessary for the proper preparation of medical devices.
Broad range of effectiveness and long service lives
Excellent material compatibility combined with powerful disinfection and cleaning
Easy and efficient to use
