PVA sponge for test tubes, it is used for the preparation of the incubators, for our queens, it is also used to give environmental humidity to the formegger by putting it well wet.

Available in two diamonds:

The diameter of 18, serves us for the tubes of 8ml, 10ml and 19ml.

The 22 diameter serves us for 43ml tubes.

To be able to handle the sponges well and be soft first I recommend filling a container of water, put the sponges and leave them a bit, so that they will absorb the water, once they have absorbed the water you will be able to handle them well, express them a little and you can use them.
