i use the Swienty instrument,bought the complete kit from them new.
I also have the original Swienty instructions on the use of the instrument,which contains the imformation about the glass tips,plus lots of other info about just about everything from collecting and care of drones,right to the inseminations and after care of inseminated queens ect ect. If you e mail Josephine at Swienty and ask if she would e mail a copy of this booklet to you i'm very sure she will.
If not then get back to me and i will help.
