We have multiple of these. It is a small glass funnel with splits into 3 spouts from it. Now, we are thinking it might be similar to a cow receiver, however, I have never seen one this small or delicate. It's 11cm in length.

We have put 3 test tubes underneath and ran water through and it does appear to distribute it relatively evenly.

What could it be?

    $\begingroup$ Why does this post have closure votes as homework? If I search google for this image I get results for glass bottles, which is certainly not what is expected. $\endgroup$ – Gaurang Tandon May 16 at 3:31
  • $\begingroup$ We have currently been calling it a funnel fork.... but I really have a feeling that isn't what its called! $\endgroup$ – hreeve1 May 16 at 7:20
  • $\begingroup$ It might be a cold finger to collect up to three fraction, fitting distillation of a micro amount (mg scale) of a single compound (head, x, tail). $\endgroup$ – Alchimista May 16 at 9:49

    $\begingroup$ My best guess is a "pis de vache" (i.e. "cow's udder" in French) which is used in distillation to collect several parts of the distillate. Though it is generally more useful during vacuum distillations, which is not the case here. See picture chemscience.com/categorie-produits.html?cat_id=249 $\endgroup$ – SteffX May 16 at 15:15
