nucleopore filter holders, these appear to be 25mm dual stage filter holders, they were used for passive sampling so they have dual stages, a yellow plug on the outlet that can be removed and some have a teflon filter on the top stage, all are used, some have numbers with tape and some dont, the box is full so probably several 100 at least you can find the link to these on vwr etc and they retail for ~$25 each
