To prepare samples for elemntal analysis of sensitive compounds inside a glove box small capsules made out of tin proved to be reliable.

For the ease of taking pictures the process of how to prepare a sample is shown outside a glove box. The capsules are tiny and relatively soft. Therefore some custom tools are needed to prepare them inside a glove box.

• Two tweezers. At least one hast to be pointy and ideally bent (Figure 2(a)).
• A micro spatula. Bent it like in this picture (Figure 2(b)).
• A small paint brush (Figure 2(c)).
• A holder for the capsules (Figure 2(d)).
