Object of the procurement 2 ultrasonic baths. These must meet the following criteria: 1. The inside size of the tank must match our inventory of bottles (sample containers) of 1 or 4 liters each. For this, an acid-resistant tank in a heavy-duty design is necessary. Oscillating tank inside L×w×d: Min. 500 mm × Min. 300 mm × 200 -250 mm. Above all, the depth must not be significantly undercut or overshot. 2. The peak ultrasonic power must be between 1100 and 1440 watts. 3. The entire system must run at a constant power to avoid overheating. This is essential for work safety and prevents damage to the sample containers and the samples. 4. The system must have a timer 5. Heating output: Adjustable to at least 50 to 90°C 6. Heavy-duty design: The tanks must be very robust and have a weight (bottles, water + acid and sample) of at least 20 kg 7. The hanging tank must be compatible with the ultrasonic bath. The material must be plastic to prevent corrosion. The tank must also be sufficiently temperature-resistant. Contact and cleaning fluid tailored to the device series, such as Tickopur R 33, is required to transfer the ultrasound to the plastic tank and its contents.
