Preset SW 3H | Ultrasonic cleaning bath with protocol recall | stainless steel | 2.75 L maximum tank capacity | with heating | drain option

Key Features

  • Constructed of high quality textured stainless steel that is easy to clean and chemically-resistant
  • Newly-developed ultrasonic generators
  • LED display shows both actual and target for ultrasonic duration and temperature
  • PreSet function allows recall of a frequently used cleaning protocol that stores time, temperature and ultrasound mode parameters.
  • Novel ultrasonic mode for degassing liquids prior to use in HPLC
  • Boost mode to increase the ultrasonic signal strength to remove stubborn residues
  • Sweep mode to ensure proper cleaning regardless of item position in bath
  • Safety shutdown feature after eight hours if no operator intervention
  • Over-temperature shutdown feature
  • Fan shutdown delay


The SW 3H ultrasonic cleaning bath from SonoSwiss is made of the highest quality stainless steel and utilizes powerful piezo transducer systems and microprocessor-controlled generators to provide the ultimate in ultrasound cleaning capability.

Applications for the SW 3H include the cleaning of instruments in medical and dental offices, the cleaning of jewellery and watch parts, and the removal of chemical residues, coking and soot from precision parts. The SW 3H is also ideal for degassing  solutions prior to use in HPLC applications.

The SW 3H features two novel functions that optimize the cleaning process. The first function is called Sweep. The Sweep function creates an even sound distribution to ensure that items are reliably cleaned no matter where they are placed in the bath. The second novel function is called Boost. Boost allows the ultrasound signal to be increased by up to 20% to ensure the removal of stubborn residues. 

The SW 3H also features a PreSet function that allows the recall of a frequently used cleaning protocol. Time, temperature and ultrasound mode parameters are stored under this function.

The SW 3H has a number of safety features incorporated into the unit. These include an over-temperature shutdown feature and a fan shutdown delay. The shutdown delay keeps the instrument's fan running when the bath is switched off until the bath temperature reaches 45°C.
