You should confirm what it is sensitive to such as oxygen, nitrogen, moisture, or both. Accordingly, you may find a suitable solution

Handling an environmentally sensitive material without a glove box can be challenging, but there are several techniques and precautions that can be taken to minimize the risk of contamination or exposure. Here are a few suggestions:

It's important to note that the specific handling techniques and precautions will depend on the nature of the environmentally sensitive material and the intended use. It's always best to consult with a professional or refer to the material safety data sheet (MSDS) for specific handling instructions and precautions.

Use a big well sealed thin transparent plastic bag,

-enclosing the balance, and

-your material to be weighed.

-another small bottle to put your weighed material into it,

You must have some access to operate the balance.

Try to create some vacuum in the bag, and then introduce some inert gas, and seal it.

Finish your weighing, and put the weighed material into the sealed bottle which now contains the inert gas, seal it and take it out.

In fact you can get such bags or disposable enclosures which can be used instead of a costly glove box.
