Article in ChemistrySelect about BuBble bags and radicals

ChemistrySelect published our article with measurement results with our BuBble bags. We investigated the production of so-called radicals; these are chemical side-products of cavitation bubbles. We showed that the bags increased the radical production with 45% while reducing the variability with 22%, compared to a 25x smaller device that we had engineered earlier in the ...

Cleaning microscope objectives

Microscope objectives are often used in very close vicinity of samples. It is therefore not uncommon to find traces of material on an objective. Cleaning an objective often involves special cleaning liquids, swabs, alcohol and/or pressurised air. However, this process is quite cumbersome since careful handling is required to avoid scratches on the lenses. Ultrasonic ...

Preventing cross-contamination during ultrasonic cleaning

During the cleaning of medical instruments such as tweezers, dental drills and tattoo needles, special attention needs to be given to prevent contamination from one instrument to end up on the next instrument. This risk on so-called cross-contamination exists especially during ultrasonic cleaning, since contamination that has been removed from an object remains inside the ...

Case study: cleaning a 3D printed model

One of the popular 3D printing techniques is DLP (Digital Light Projection), in which a resin is being cured layer by layer using UV projections. This is a very accurate printing technology and results in detailed three-dimensional objects. However, after printing it is required to remove the uncured resin. This can be a challenging task ...

BuBble bag vs. glass beaker – which one gives better cleaning?

Our BuBble bags enhance the formation of bubbles in an ultrasonic bath and should therefore clean better thane.g. glass or plastic beakers that people often use in ultrasonic baths. But how much better is the cleaning with BuBble bag really? In order to measure that, we used so-called cleaning indicators, which visually represent the the ...
