Syringe Coupler, Luer Lock Adaptor (Polypropylene) - Female-to-Female (Qty: 10)

I used them for the transfer of a plant distillate from one container to another.

The ease of mixing liquids in syringes are incredible now!! You neeeed these. Just make sure there twisted tight.

These are inexpensive. The material is not compatible with some solvents. Obviously they are intended for single use only, but if they come in contact with something like DMSO, that single use had better be less than 20 minutes. Based on past experience I would guess that alcohol may have the same effect. The material becomes extremely brittle in contact with these fluids.I am not terribly disappointed, but the next set of luer unions that I buy will probably be a polypropylene material instead.

They do exactly what they're supposed to I would definitely recommend these syringe adapters they come in handy when going from one syringe to the next. And having minimal contact loss.

The only way to transfer liquid from one syringe to another without mask, or loss of product.
