At my workplace we will soon begin diluting a solution to specific concentrations, this is done within a specific container.
The solution to be diluted is provided by a manufacturer in the following type of bottle :
The contents inside this bottle can only be retrieved with a syringe. However, we need to transfer volumes in the ranges of $ 0.015 \,mL - 0.06 \,mL $ ,with syringes we cannot be confident (because we have to eyeball it real hard).
So we think of course to transfer from the bottle to a beaker and then using a micropipette to transfer to the desired container and dilute. The problem is that the solution to be diluted is extremely expensive , and every unnecessary transfer to a beaker will cause some of our solution to be lost , beakers need to be also washed THOROUGHLY if they are to be reused.
Question : Are there any viable instruments that have a needle to enter the bottle and enough accuracy to transfer $ 0.015 \,mL - 0.06 \,mL $ ? Can you think of any way we can get around our problem?. We hope we can do just 1 transfer from Manufacturer bottle to our desired container to be diluted. Upon researching online we have not had much luck.
Opening , and replacing the cap of Manufacturer bottle gives problems with sterile properties of solution , as well of greatly reduces the expiry date.
Transfering from manufacturer bottle to beaker and then micropipetted to desired container to be diluted , gives rise to problems of sterile , as well as time consuming due to having to thoroughly clean the beaker, causes loss of solution.
I know this question may not be appropriate for this site , but I do thank you for your help and time.
