CliniEco Dental Ultrasonic Cleaner — 4 L Benchtop, CS4.0 Dual-Frequency 32/48 kHz

Quick answer: A 4 L tank with both frequencies on one dial and a five-step timer — enough for the loose instruments from one chair, and not enough for a full cassette.

Most benchtop ultrasonic cleaners sold online are built for jewellery and eyewear. They are small, they are cheap, and the timer is a single knob you cannot repeat. The CS4.0 is the same platform as our 6 L unit in a smaller footprint: a 4,000 ml stainless tank, 32 kHz and 48 kHz on the same generator, controlled heating with a temperature read-out in both °C and °F, a drain valve, and a timer with five fixed steps so the same load gets the same cycle next week.

Scope of use. This is a cleaning device. It removes soil — cement residue, polishing paste, dried blood in hinges and threads — as a step in instrument reprocessing. It makes no microbicidal claim, and it does not replace any later step in the workflow set out in the instrument manufacturer’s instructions for use. The Health Canada guidance on reprocessing information is why the instrument manufacturer’s instructions — not the cleaner’s specification sheet — decide what happens to a given instrument after it comes out of the tank.

What are the CS4.0 specifications?

The numbers below are the ones that decide whether the unit fits a room: how much liquid you have to mix, how long the cycle runs, and what the electrical certificate actually names.

Which tank size in the range fits your room?

The size break in this range is not a matter of taste. A standard dental instrument cassette does not fit a 4 L tank, and it does fit a 6 L tank. If your day is one chair’s hand instruments, the 4 L is the whole requirement; if a cassette goes in the tank, you are shopping one row down.

Two practical checks before you order. First, measure the longest instrument you routinely clean — a 4 L tank sets the limit sooner than most people expect. Second, count how many times a day you would run the tank: a single load in the morning and a single load at close is the pattern this size is built for, and three or four loads is the pattern that pushes a practice into the 6 L class.

How do you run a repeatable cleaning cycle on the CS4.0?

The value of this unit in an inspection is that the cycle can be described in one line and repeated tomorrow by someone else. That means fixed numbers, not judgement calls.

Two habits make the difference. Keep the basket in — instruments resting on the tank floor leave shadows in the cavitation field and wear the stainless. And change solution on a schedule rather than when it looks dirty: the log is the evidence, and a tank that is topped up instead of changed cannot be reconstructed afterwards.

What an infection-control inspection asks for is the record, not the machine. Ontario’s provincial reprocessing guidance asks for documentation and maintenance of records for each component of the cleaning, disinfection and/or sterilization process, based on the manufacturer’s recommendations, and repeats that records must be retained according to the facility’s policy (Public Health Ontario, “Best Practices for Cleaning, Disinfection and Sterilization of Medical Equipment/Devices In All Health Care Settings”, 3rd edition, checked 2026-11-07). A unit with a drain valve, a visible timer and a stable temperature set-point is what makes that record short enough to write at the end of a shift.

What does the cETL mark cover, and what does it not?

The CS4.0 carries a cETL mark from Intertek under report 220112139GZU-001. The mark on the unit is an ETL mark issued by Intertek, tested against UL 73 and CSA C22.2 No. 68. It is an electrical safety certificate. It is not a UL listing and it is not CSA certification, and it says nothing about how well the tank cleans. Canadian reprocessing practice sits on a separate standard, CSA Z314:23, whose scope puts documentation inside the reprocessing quality system rather than inside the appliance.

What is in the box, and what should be ordered with it?

One cleaner, 4 L, 110 V with a North American plug, plus the manufacturer warranty. The stainless basket is an accessory rather than a line item, so say so on the order if you want it in the same box. Nothing else is required to run a cycle except solution and water — no plumbing connection, no drain pump.

Multi-enzyme ultrasonic cleaning solution is what goes in the tank, sold as a 1 L bottle or a 5 L pail and diluted 1:400 to 1:600. The 6 L CS6.2 is the unit to look at if your load grows into full cassettes. Read how to choose a tank size and what to record on the cleaning log before you commit to a size.
