How to clean your test sieves

Thorough and gentle

If you sieve regularly, you also have to clean regularly: because clean test sieves are a central prerequisite for perfect sieving results. Deposits and stuck particles reduce the permeability of the metal wire mesh sieve - and this reduces the reproducibility and accuracy of your results.

Simple cleaning often does not remove all stuck particles from the test sieve. To thoroughly and gently remove even the finest particles from the test sieve, you should therefore work with an ultrasonic cleaning device. This cleans more thoroughly and saves time at the same time.

What options does Haver & Boecker offer you for sieve cleaning?

For test sieves with a diameter of up to 230 mm we offer the HAVER USC 200 S. If several sieves are to be cleaned at the same time, we recommend the HAVER USC 200 Multi. Here you can clean up to 5 test sieves at the same time. For sieve diameters up to 500 mm, we offer the HAVER USC 500 S.

Our cleaning equipment

Single sieve cleaning

The two ultrasonic cleaning units HAVER USC 200 S and HAVER USC 500 S have a "Sieve cleaning" function so that your test sieves are optimally cleaned. In combination with the HAVER USC cleaning concentrate, you can achieve thorough and energy-saving sieve cleaning.

Ultrasonic cleaning device for test sieves up to 500 mm — HAVER cleaning device USC 500

Multiple sieve cleaning

With the HAVER USC 200 MULTI you can clean up to five test sieves simultaneously. The sieves can have a size of up to 200 mm. The easy handling and gentle cleaning of your measuring equipment speak for cleaning with the help of an ultrasonic cleaning device.

Practical tip: The correct treatment of the finest mesh sizes

Test sieves with fine mesh sizes up to 500 µm must be cleaned in an ultrasonic bath, otherwise they tear quickly. You should make sure that no alkaline cleaning liquids are used. These damage the surface of the wire mesh. After the ultrasonic bath, rinse the test sieves with clear water and blow out the sieve bottom with compressed air to remove any streaks. Let the sieves drain for about 5 minutes and dry for a maximum of 30 minutes at a temperature of 80°-100°C. You can remove any remaining trapped boundary grains by lightly tapping the sieve frame against a wooden or rubber pad. Do not use brushes or paintbrushes.
