Have you ever tried doing precise work while wearing oversized rubber gloves attached to a giant glass box? Neither had I, until today. My first experience working in a glovebox turned out to be one of the most memorable parts of the experiment.
A glovebox is essentially a sealed chamber filled with an inert gas, usually argon or nitrogen. It allows researchers to handle chemicals that would react immediately with oxygen or moisture from the air. While the concept sounds straightforward, actually working inside one takes a bit of getting used to. Every material has to be transferred through a small airlock before it can enter the glovebox, making sure that no outside air contaminates the atmosphere inside. It is a fascinating piece of equipment that most people probably never think about, but in battery research it plays a very important role.
Getting used to four pairs of gloves
Before I could even start my experiment, I had to get myself into the glovebox. My hands were already covered by two pairs of gloves before I even reached the large rubber gloves attached to the box. Because there is a slight pressure difference inside the glovebox, pushing my hands into the gloves required more force than I had expected. Once my hands were inside, I had to put on yet another pair of gloves inside the glovebox to keep everything as clean as possible. In total, I was now working with four layers of gloves.
At first, every movement felt surprisingly clumsy. Suddenly my fingers seemed twice as big as usual and simple tasks such as picking up a small sample or opening a container required much more concentration than expected. I came close to knocking over a sample more than once, but after a while I slowly got used to my oversized "new hands". By the end of the experiment, working inside the glovebox already felt much more natural.
The experiment itself
The reason I needed the glovebox was the electrolyte used in my experiment. Since it reacts with air, all preparation had to take place inside the protected atmosphere of the glovebox. The goal of the experiment was to investigate how my synthesised capsules behaved when exposed to the electrolyte and whether they released any of the encapsulated material into the solution.
After preparing the samples, they had to be transferred out of the glovebox so they could be analysed with a spectrophotometer, an instrument that measures how much light a sample absorbs. This meant carefully planning which steps had to happen inside the glovebox and which could safely be carried out outside. Even though the experiment itself was not overly complicated, moving materials in and out of the glovebox without contaminating them required careful attention throughout the entire process.
Looking back
One thing that surprised me was how safe the glovebox felt. Being separated from the chemicals by a solid glass window and thick gloves gave me a sense of security, especially when working with air-sensitive materials. Instead of worrying about accidentally coming into contact with the chemicals or breathing in anything harmful, I could fully concentrate on the experiment itself.
Overall, this first experience showed me that working with specialised laboratory equipment is a skill in itself. I am glad I had the opportunity to try it and I am sure that the next time I use a glovebox, it will already feel much more familiar.
- From Colombia to Berlin: Finding My Way in a New WorldIt was almost 11 p.m. when I arrived in Berlin. After a long journey from Colombia, all I wanted was to get to my accommodation, take a shower, and finally sleep.
Instead, I missed my train. Thinking it would follow the same route as the previous one as it would in my hometown of Medellín I confidently boarded the next train. About twenty minutes later, I realized something was wrong. I was heading in the wrong direction.
As if that was not enough, my phone battery was almost empty. Suddenly, I found myself alone in a city I had never visited before, late at night, speaking a language I did not understand, with no idea how to get back.
This was not how I had imagined the beginning of my first international trip....
- Precision interface chemistry pushes perovskite solar cells beyond 26% efficiencyAn international research collaboration has developed a new molecular strategy for controlling one of the most critical interfaces in perovskite solar cells. The resulting solar cells reached a power conversion efficiency of 26.19% in the n i p architecture, together with strong operational stability under prolonged illumination and elevated temperature. The results have been published in the Journal of the American Chemical Society.
- 83 pupils at Girls'Day at HZBOn 23 April 2026, the annual Girl’s Day took place, giving pupils an insight into various career paths in the fields of science and technology. 83 pupils visited the Adlershof and Wannsee sites and enjoyed a day full of exciting experiments.
