What the result means: this ultrasonic cleaning indicator monitors cavitation activity at the tested location under defined conditions. Its endpoint does not directly demonstrate instrument cleanliness, soil or protein removal, disinfection or sterilization.
One cavitation test. Three monitoring tasks.
Use a repeatable test setup to follow ultrasonic bath performance over time.
Check a reference position
A routine ultrasonic cleaner cavitation test checks the response at defined positions. Retain the same bath preparation, holder, orientation and exposure for meaningful trending.
Compare different areas
Place separate vials at distributed, documented positions to identify differences in the indicator response across a tank, basket or test plane.
Document the return to use
Use the indicator as part of your equipment procedure after installation, maintenance or repair. A vial test alone does not constitute complete IQ, OQ or PQ.
For hospital CSSD / sterile processing, dental ultrasonic cleaner testing, laboratories and industrial ultrasonic baths. Tabletop, multi-level and multi-bay systems require an equipment-specific layout that meets the IFU conditions.
How to use the ultrasonic cavitation indicator
A practical overview of IFU Rev. 01. Read the complete instructions before use.
A sealed, ready-to-use indicator
The vial contains blue-green reactive solution and glass beads. Ultrasonic exposure produces a visible response under the defined test conditions.
Interpret the endpoint after the full standard cycle. An early change does not shorten the specified 5-minute exposure.
Check the vial
Confirm the seal is intact, the glass is undamaged, the expiry is valid and the solution is blue-green before exposure.
Prepare the bath
Follow the cleaner and detergent instructions for chemistry, fill level and degassing. Confirm 18–70 °C. Use an empty basket or tray, without instruments or production load.
Fix the position
Keep the sealed vial fully submerged and horizontal for the entire cycle. A suitable reusable vial holder helps maintain reproducible positioning.
Run the defined cycle
Apply an uninterrupted 5-minute ultrasonic exposure. An early color change does not shorten the specified test cycle.
Read promptly
Remove immediately after the ultrasonic stage. Read preferably within 1 minute and no later than 5 minutes after the cycle ends, using the current color reference.
Record and review
Log cleaner ID, position, bath conditions, REF, LOT, EXP, endpoint time, result and operator. Investigate an unsatisfactory response before repeating the test.
Automated ultrasonic washers: use only during a separately accessible ultrasonic stage within the stated conditions. Remove the vial before thermal disinfection, hot rinsing or drying. Do not run it through a complete washer-disinfector cycle unless MEDIWISH has specifically validated that exact cycle.
Read the endpoint, then record the result
These criteria refer to the standard 5-minute exposure and the prescribed read window.
Fail
No visible response was achieved under the applied 5-minute conditions. Follow the facility procedure and seek service if the failure repeats.
Unsatisfactory response
The response is incomplete or delayed. Review preparation, position, temperature, chemistry and equipment condition; investigate and repeat.
Acceptable endpoint
The specified indicator endpoint was achieved at the tested location. Record it under the defined cycle conditions.
A delayed yellow response after 5 minutes is not a standard acceptable result. The IFU describes a diagnostic extension up to 7 minutes. Do not use later fading, drift or reversal to change the result recorded in the prescribed read window. Do not interpret exposure shorter than 3 minutes.
Routine checks and periodic cavitation mapping
The supplied MEDIWISH instructions recommend the following minimum layouts for a single tank or test plane.
Document each position
Map a single tank or test plane with separate, fully submerged horizontal vials. Follow the applicable minimum point count shown below and your equipment-specific procedure.
For multi-level equipment, treat each level as a separate test plane. Treat each bay as an independent tank.
Small tank
Up to and including 5 L
Medium tank
Over 5 L and up to 20 L
Large tank
Over 20 L
The image illustrates distributed test positions, not validated placement coordinates. Final positions depend on tank geometry, baskets, transducer zones and the equipment procedure. These are manufacturer recommendations, not a universal regulatory requirement.
Multi-level systems
For routine checks, use at least one vial in each basket on every level. Map each level as a separate test plane.
Multi-bay systems
Treat each bay as an independent tank. Apply an appropriate layout to each bay and keep its records separate.
Keep comparisons meaningful. Compare endpoint times only when equipment, liquid, detergent concentration, temperature, degassing, load, placement and test duration are consistent. The result is qualitative and comparative; it is not a calibrated acoustic measurement.

Choose the test that answers your question
Cavitation testing and cleaning verification address different parts of an ultrasonic cleaning process.
| Method | What it helps evaluate | Important distinction |
|---|---|---|
| Colorimetric cavitation vial | Qualitative indicator response at a defined bath location under specified conditions | No calibrated dB or W/cm² value; no direct proof of instrument cleanliness |
| Aluminium foil / physical challenge | Visible effects on a standardized physical target | Requires controlled material, placement and exposure; not a residual-protein test |
| Test-soil cleaning indicator Ultrasonic cleaner test strips · CEI indicators | Removal of a standardized test soil under an applicable cleaning procedure | A separate cleaning challenge; not interchangeable with a colorimetric vial |
| Residual-protein test | Residual protein on sampled instruments or surfaces after cleaning | A sampling result; not a cavitation test or proof of sterility |
| Acoustic measuring instrument | A specified acoustic quantity under the instrument's measurement method | Requires appropriate method and calibration; does not establish cleanliness or sterility |
For a broader monitoring program, combine the applicable cavitation check with a suitable cleaning efficacy indicator and residual protein testing according to the facility procedure.

Questions before ordering
Compatibility, test scope, documents and commercial supply.
Is MZS-5635 compatible with my ultrasonic cleaner?
Check the equipment frequency (≥35 kHz), bath temperature (18–70 °C) and ability to perform the defined 5-minute test with the vial fully submerged and horizontal in an empty basket or tray. Brand name alone does not establish compatibility. Send your equipment model and cycle details if you need a technical review.
Can I use it for dental ultrasonic cleaner testing?
Yes, in dental instrument reprocessing areas when the cleaner and test setup meet the stated IFU conditions. Use it as a cavitation check within the clinic's monitoring procedure; assess cleaning efficacy and residual contamination separately where required.
How often should an ultrasonic cleaner be tested?
The supplied IFU describes routine testing daily or weekly according to facility policy. Determine frequency from the equipment instructions and your approved procedure. Periodic mapping is recommended at setup, planned intervals, after repair or when a routine result is unsatisfactory.
Does a yellow vial prove that instruments are clean?
No. Transparent yellow by the specified endpoint demonstrates the indicator response at that test location under the defined conditions. It does not directly prove blood, soil or protein removal, disinfection or sterilization.
What is the difference between an indicator vial and ultrasonic cleaner test strips?
MZS-5635 is a sealed colorimetric vial for checking cavitation activity at a defined bath location. Our ultrasonic cleaner test strips use a synthetic test soil to assess soil removal during an ultrasonic cleaning cycle. The two formats assess different aspects of the process. Follow the current instructions and acceptance criteria for the selected product.
Is this a cavitation meter or ultrasonic dosimeter?
No. The visual result is qualitative and comparative. MZS-5635 does not provide a calibrated value in decibels, W/cm² or another physical measurement unit.
Do I need a reader or a special holder?
An electronic reader is not required for the standard visual result. A dedicated holder is not mandatory for basic use, but a suitable reusable vial holder is recommended for fixed, repeatable positioning during mapping, trending and post-service checks.
Can I run the vial through a full washer-disinfector cycle?
Use only in a separately accessible ultrasonic stage within the specified conditions and remove the vial before thermal disinfection, high-temperature rinsing or drying. A complete washer-disinfector cycle is outside this instruction unless that exact cycle has been specifically validated by MEDIWISH.
Can I request regulatory and quality documents for MZS-5635?
MZS-5635 is CE-marked. The applicable EU Declaration of Conformity, current ISO 13485 quality-management certificate and destination-market documents are available on request for supplier qualification, tenders and distribution. Send your company, country, selected model and document requirements to MEDIWISH.
How do I buy ultrasonic cavitation test vials or request private-label supply?
