Flammable Solvent Beaker Kits
Keep flammable solvents inside beakers while the ultrasonic bath delivers the energy.
Never directly fill a conventional ultrasonic cleaner with flammable solvents. Use a secondary containment method such as beaker kits.
Why Beaker Kits
Operating an ultrasonic cleaner not designated as explosion proof with the tank filled with a flammable solvent poses a serious explosion hazard. However, a standard ultrasonic cleaner can be operated safely using the following method: Fill beakers with flammable solvent and position them in a water-filled ultrasonic cleaner. Small parts can be cleaned inside covered beakers which are partially immersed in water. The ultrasonic waves pass through the beaker walls and into the solvent. This operation should be carried out with sufficient ventilation to prevent solvent vapor accumulation.
Safety Alert: Ultrasonic cleaners supplied with beaker kits are not explosion-proof. Keep the area around the tank free of solvent vapor. Beaker kits should be operated inside a fume hood or with a local exhaust system.
Safer solvent handling
Solvent stays inside capped glass beakers; only water fills the main tank.
Flexible chemistry swaps
Change solvents by swapping beakers; keep the bath water and tank in place.
Great for small batches
Ideal when you clean small parts, prototypes, or R&D samples with flammable solvents.
What is in the Kit
Kit components
- 2 x Glass beakers
- 2 x Polypropylene lids to contain vapor
- 2 x Rubber rings to position beaker height in liquid
- 1 x Stainless steel tank cover with 2 holes to support beakers

How the setup works
- Holds beakers upright in the water bath
- Transfers ultrasonic energy evenly to each beaker
- Easy in/out for chemistry changes
- Ultrasonic energy passes through water, beaker walls, and solvent
- Keeps solvent volume low and contained

FAQs
Why use beaker kits for flammable solvents?
They isolate solvent inside covered beakers while the tank holds only water, reducing vapor exposure and ignition risk.
Do I need a flammable-solvent-cleaning tank with beakers?
Follow your EHS requirements. Beakers reduce risk, but classified hazardous areas may still require a flammable-solvent-cleaning rated unit.
How much solvent can I run?
Kits are limited to 2 x 1-liter beakers. We do not recommend using larger beakers or a larger number of beakers. This would increase the amount of solvent vapor produced during operation. A larger vapor cloud has increased risk of contacting an ignitable spark from the generator on the bottom of the tank.
Why can’t I use the heater on the tank?
Heating the solvent will increase the rate of evaporation and the risk that solvent vapor will come into contact with a spark from the generator on the bottom of the tank.
Can I run different solvents at once?
Yes—separate beakers allow different chemistries in the same water bath. Label each beaker and keep lids on.
How often should I change the water bath?
Keep using the same bath as long as the water looks clear.
