Product Description :

22 Litre Heated Digital Ultrasonic Bath 

Nominal Tank Capacity :

22 Litres

Size selector :

«Smaller  Larger»22

Product Specification :

These heated ultrasonic baths are suitable for sonochemistry, degassing and sample dissolution and cleaning of delicate or fragile components/glassware especially where there may be a risk of breakage as a result of manual cleaning. The addition of heaters on this range ensures that optimum operating temperature for maximum ultrasonic efficiency is reached rapidly.

Using high performance piezoelectric disc transducers to ensure, consistent ultrasonic activity throughout the tank liquid ideal for laboratory routines. The activity is called cavitation - this is created by pressure waves, which causes bubbles to form and collapse.

Comprising of a stainless steel tank housed in a durable paint finished outer case. Wipe clean controls feature bold 2 digit LED display of actual temperature, adjusting temperature and time and activating sonics.

Heat Up Times :

Heating/Cooling information :

1. It is recommended that to achieve consistent heating, minimise evaporation and act as a dust cover, preventing contamination when ultrasonic bath is not in use, it should be covered with LD series accessory lid - detailed below.

2. It is essential that either BSK series Baskets or SLU series Lids are used in order to prevent items from touching bottom or side of the tank - accessories detailed below.

Warranty Period :

3 Years

Safety features :

1. A Safety cut-out liquid level sensor constantly monitors the water level and switches the heaters and ultrasonics off when low liquid levels are detected. An audible sounder is also triggered.

2. Water Depth

  The tank overall depth is 150mm.

  The tank overall maximum working depth is 120mm.

  The water level sensor is fitted at a depth 60mm from top of the tank, providing minimum water level - approx 90mm.

  The sensor is fitted adjacent to "MIN -----------" stamped into the tank, this is minimum water level for the ultrasonic bath. To prevent the 'low liquid alarm' being activated, it must be filled above this level with 'tap' water/conventional ultrasonic bath detergents.

3. Over temperature alarm operates +10°C with heater cut off, indication.

4. Bath is fitted with non-slip rubber feet for safety.

Ultrasonics advisory information.

1. This Ultrasonic bath is designed for intermittent use only, no permanent on setting.

2. In use do not allow items to touch base of the tank, BSK series Baskets or SLU series Lids are recommended in order to prevent items from touching bottom or side of the tank - accessories detailed below.

Ultrasonics specification.

  Sonics, output = 200 ppw

  Modulation = 100Hz

  Operating frequency = 30-40kHz

  Transducers = 6PZT

  Noise level <70 dBa @ 1m with accessory SL Lid fitted.

Features and Benefits :

1. This bath is ideal for the routine cleaning of delicate or fragile components/glassware and where there may be a risk of breakage as a result of manual cleaning.

2. High power piezoelectric transducers ensure maximum ultrasonic power throughout working area. Constant tuning eliminates the need for frequency sweeping.

3. Noise reduction techniques for reduced noise levels in a laboratory using insulation between vibrating and static surfaces reducing the ultrasonic ‘shrill’ to a vigorous ‘hum’ and using disc transducers rather than pillars for quieter operation.

4. Variable temperature control up to 69°C which can be digitally set and displayed in increments of one degree.

5. Indication set point temperature.

6. Easy to read bold temperature display.

8. Timer allows variable operation up to 30 minutes.

9. A drain is fitted on the DU-22 models for ease of emptying the bath.

10. Equipped with an illuminated on/off mains switch.

11. Wide range of bath sizes from 4 litre up to 22 litre suiting a variety of applications. Full use can be made of the bath to provide maximum working area.

12. Totally unobstructed, stainless steel tank.

13. Concealed heater and temperature sensors.

14. Small bench top footprint.

15. Fitted with non-slip rubber feet for safety.

16. A 304 spec stainless steel tank gives good resistance to many substances and a clean appearance throughout its working life.

17. Sturdy construction - powder coated exterior providing a durable chemical resistant.

18. Built to latest safety standards and supplied with comprehensive operating instructions and Three-year warranty.

19. A range of accessories available.

20. Easy to clean tank being crevice free .
