Clifton Ultrasonic Baths

These industrial strength ultrasonic baths are designed for demanding applications. The baths are also ideal for cleaning delicate or fragile components which may otherwise be damaged by mechanical cleaning.

Supplied complete with lid and basket.

Available Models:-

 

·         SW1H

·         SW3H

·         SW6H

·         SW12H

·         SW30H

The baths are available from 1 to 30 litres capacity and feature eco and dynamic sonic modes. Eco offers quieter gentler ultrasonic activity whilst dynamic running provides vigorous cleaning.

The touch pad, wipe clean, control panel with rotary dials for time and temperature, can be set between 30°C and 80°C in 5°C increments. The timer can be selected to operate between 1-30 minutes or continuously up to 6 hours.

Clifton ultrasonic baths are constructed from high quality stainless steel for durability, with side lifting handles on models SW3H upwards for easy transportation.

Potassium Hydroxide.

Potassium hydroxide is an inorganic compound with the formula KOH, commonly called caustic potash.

Potassium Hydroxide is noteworthy as the precursor to most soft and liquid soaps as well as numerous potassium-containing chemicals.

Potassium hydroxide can be found in pure form by reacting sodium hydroxide with impure potassium. Potassium hydroxide is usually sold as white or translucent pellets, sometimes yellow, which will become tacky in air because KOH is hygroscopic. Consequently, KOH typically contains varying amounts of water (as well as carbonates).

Its dissolution in water is strongly exothermic, meaning the process gives off significant heat. Concentrated aqueous solutions are sometimes called potassium lyes. Even at high temperatures, solid KOH does not dehydrate readily.

Potassium hydroxide has many uses:-

• Precursor to other potassium compounds, eg fertilisers
• Manufacture of biodiesel
• Manufacture of soft soaps
• As an electrolyte
• Cleaning and disinfection
• As a main active ingredient in chemical "cuticle removers" used in manicure treatments

Health information

• Potassium Hydroxide is highly corrosive and contact can severely irritate and burn the skin and eyes leading to damage
• Potassium Hydroxide can affect you when inhaled and by passing through the skin
• Contact can irritate the nose and throat
• Inhaling can irritate the lungs causing a build up of fluid
• Exposure can cause headaches, dizziness, nausea and vomiting
• It may cause skin allergy.

All health and safety data information must be followed when using this chemical

Ultrasonic Baths

An ultrasonic cleaner is a cleaning device that uses ultrasound (usually from 20–400 kHz) and an appropriate cleaning solvent (sometimes ordinary tap water) to clean delicate items. The ultrasound can be used with just water, but use of a solvent appropriate for the item to be cleaned and the soiling enhances the effect. Cleaning normally lasts between three and six minutes, but can also exceed 20 minutes, depending on the object to be cleaned.

Ultrasonic cleaning penetrates even microscopic openings to provide complete cleaning of the objects treated. This makes it one of the most effective, economical and powerful cleaning methods available. It has applications in laboratories, dental and medical technology, microelectronics, precision engineering, cosmetics, optics and the automotive industry. Ultrasonic cleaners are used to clean many different types of objects, including jewellery, lenses and other optical parts, watches, dental and surgical instruments, tools, coins, fountain pens, golf clubs, window blinds, firearms, musical instruments, industrial parts and electronic equipment. They are used in many jewellery workshops, watchmakers' establishments, and electronic repair workshops               

Modern baths tend to have a heavy duty ultrasonic generator which ensures that the ultrasonic output remains constant, regardless of the bath temperature, fill level and cleaning material. This feature guarantees consistent and reproducible cleaning results. 'Frequency sweeping', a frequency modulation of the ultrasonic output generated, prevents 'standing waves' from being generated and ensures extremely homogeneous energy distribution in the cleaning bath.

 

Ultrasonic cleaning uses Cavitation bubbles induced by high frequency pressure (sound) waves to agitate a liquid. The agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass, rubber, and ceramics. This action also penetrates blind holes, cracks, and recesses. The intention is to thoroughly remove all traces of contamination tightly adhering or embedded onto solid surfaces. Water or other solvents can be used, depending on the type of contamination and the workpiece.

 

There are various ways to test the level of ultrasonic activity within an ultrasonic bath..

 

There are a number of recommended tests for establishing levels of ultrasonic activity in the bath.

The foil test involves suspending a strip of foil into various locations around the tank. The foil should not touch the base of the tank and should be held in position for around 1 minute. It should then be removed and there should be an even distribution of perforations and small holes on the surface of the foil.

Another test requires the use of Brownes soil test strips. These are plastic strips which have been contaminated to simulate the contamination which might affect surgical instruments. After running an ultrasonic cycle the strips should be taken from the bath and all contamination should have been removed.

An ultrasonic energy meter can also be used to test the level of ultrasonic activity within the tank.

Laboratory Detergents

It's important to make sure you choose the right detergent for your laboratory tasks whether they are for manual washing or for use in a washing machine.
 
As the sensitivity of analytical techniques has increased, the importance of stringent sample preparation and the quality and purity of the reagents are integral to getting good results. Even the best technique can be compromised by contaminated glassware or other lab utensils.

In the past, cleanliness was assured with toxic and aggressive products such as sodium hydroxide or Sulfo-chromic acid solutions that were very unpleasant to use. Fortunately lab detergents have come a long way. Today most labs have washing machines minimising effort and exposure to cleaning chemicals.

The issue now is ensuring that glassware is not contaminated with the detergent itself in the form of residues after cleaning. The detergent must be effective against contamination but not become a contaminant itself! A tall order when you consider the breadth of different tasks in specialised laboratories involving multiple types of contamination with various physical and chemical properties.

That’s the reason why the Labwash® Premium detergents range was developed in collaboration with experts. The range is extensive and includes good all round performance plus specialist products for specific requirements in different applications in pharma, petrochemicals, food industries, clinical labs etc..

Reliable processes are only possible with thorough, residue free cleaning and Labwash® delivers.

Excellent cleaning with no residues: Wide range of detergents suited to different cleaning tasks

High purity biodegradable ingredients: All raw materials fulfil the requirements of environmental protection.  Ecologically inert

High activity but low consumption: Labwash® Premium is concentrated but really efficient at low concentrations

Compatible with most materials: Labwash® Premium acts against contamination not the material being cleaned

1, 5, 10 and 20 l plastic packs: A wide range of packaging, easy to handle, adapted to your consumption

 

P&R Labpak are proud to offer this range of detergents to its customers.  We have a cross reference list to help customers choose which detergent is best suited for their needs if they want to swap from their existing brand so as to save money.
