Fast, Quiet, Thorough Lab Instrument Cleaning and Sample Preparation with Ultrasonic Cleaners

tova-lab-large.jpg

Tovatech’s Ultrasonic Cleaners are ideally suited for the stringent, high quality cleaning demands of all types of labware: glass, plastic, or metal.

High Grade Cleaning of Lab Instruments and Efficient Sample Preparation with Ultrasonic Baths

  • Efficient cleaning of sieves, reusable filters, beakers, bottles, vials, pipettes, plasticware, labware, glassware, and other lab instruments
  • Disperses and dissolves samples
  • Degasses solvents
  • Deep thorough cleansing action superior to scrubbing or even using steam
  • Up to 60 times faster than traditional cleaning methods
  • Thoroughly cleans hard to reach crevices and corners
  • No manual contact; ensures better cleaning with no smudging or streaking
  • Cleans both routine and critical lab instruments and equipment
  • Consistent, repeatable, predictable cleaning process gives perfect results every time!

Traditional cleaning methods in the lab are slow, cumbersome, and time consuming.  Depending on the type of labware, you may need specialized brushes and equipment to ensure thorough cleaning that does not leave residue, stains, or spots.  In addition, improper and careless manual handling increases breakage risk when cleaning delicate items. 

Tovatech’s Ultrasonic Cleaners are an elegant solution to your labware cleaning needs.  Chemical cleaning solutions agitated by ultrasonic waves give you superior, deep penetrating cleaning action unmatched by any manual cleaning process.  Ultrasonic agitation creates millions of microscopic bubbles that implode releasing vast quantities of energy.  This implosion or cavitation rapidly increases the local temperature and releases a highly energetic liquid stream that collides with the surface of the object being cleaned.  Ultrasonic cavitation along with the properties of the chemical cleaning solution results in micro-scrubbing of the soiled parts. 

Choosing the right combination of equipment and chemical solution can be a challenge.  There are several gotchas that you need to watch out for.  This is where we come in.  Our vast experience with laboratories of every type and size will help in guiding you towards the most cost effective approach that will match your budget without compromising on your cleaning needs.  Call us and we will help you make you the right choice quickly.

Designed to Fit Seamlessly into the Lab Environment

The Elmasonic P line of ultrasonic cleaning units is the most popular range in the lab.  With its choice of two frequencies (37 and 80 kHz), variable power over a broad range, and detailed digital display, the P line offers unique versatility to perform many different operations.  Select operation at 80 kHz for virtually silent cleaning of fragile instruments and even fine capillary tubes. 

The Elmasonic P ultrasonic cleaner works in four modes: Normal, Sweep, Pulse and Degas.  In Normal mode, the Elmasonic unit produces a stabilized frequency field, forcing the liquid to circulate and mix.  Mixing, dispersing, emulsifying, and dissolving samples are most efficiently accomplished in this mode.  In Sweep mode, frequencies are shifted continuously to ensure that cavitation occurs uniformly throughout the tank.  Cleaning of glass, metal, and plastic surfaces achieves highest efficacy in Sweep mode.  Pulse mode produces intermittent spikes of additional power .  Freshly mixed cleaning liquids are saturated with air.  This lessens cleaning effectiveness by suppressing cavitation.  Degas mode removes entrained air ensuring maximum cleaning efficiency.

The Elmasonic S and P models have several automated functions.  The AutoDegas option runs the unit in Degas mode for 10 minutes, enough time to thoroughly degas the cleaning liquid.  AutoStart begins ultrasonic processing when the solvent reaches the set temperature.  In addition, a safety feature automatically shuts down the Elmasonic unit after 12 hours of continuous operation.  Hence, even if you do forget to switch off the unit before you leave the lab you can rest assured that neither the unit nor your equipment is damaged.

If this is your first time selecting an Ultrasonic Cleaner, you may have questions.  Choosing the right combination for your specific situation can be challenging.  If you are unsure or are trying a new material, please do talk to us first.  We will quickly help you identify the exact ultrasonic cleaner unit and cleaning chemistry combination that you need.  Just call us. 

Sample Preparation and HPLC Solvent Degassing

In addition to regular cleaning, the Elmasonic P and S are excellent for sample preparation.  Consistent, reproducible sample prep is an essential requirement in most labs.  Elma ultrasonic baths give you consistent results whether you are dissolving samples in one flask or twenty.  All heated models can be set from 30 – 80°C.  The Elmasonic P models are the most powerful bench top units available, able to disperse nanoparticles and dissolve difficult samples.  Adjustable ultrasonic power and dual frequency allow dispersion of sensitive samples such as liposomes.  The AutoDegas and AutoStart features of S & P units combined with Elma’s state-of-the-art microprocessor controlled ultrasonic generator ensure you get reproducible results that meet your SOP guidelines. Specifically designed lab accessories like beaker holders, Erlenmeyer flask clamps, cooling coils, test tube racks, acid-resistant tank liners, and specialized accessories for contamination extraction from samples ensure that all your laboratory needs are addressed in a single unit. 

If you use an isocratic HPLC system without a vacuum degasser, an ultrasonic bath is an excellent alternative for solvent degassing.  The Degas mode will remove entrained air from your HPLC solvent in only 10 minutes. 

We can address your specific laboratory needs drawing from our vast experience.  For effective cleaning the ultrasonic cleaner must use the right cleaning chemistry, operate at the right temperature, and use the correct frequency.   The material being cleaned, its tolerance for ultrasonic vibrations, and the type and degree of soil, determine this.  Call us and we will quickly help you identify the right combination and even suggest accessories that will enhance your cleaning process.
