Dispenser Bottle for Consolidants

[DPS Ammonite]

I found a great dispenser bottle for Butvar 76  dissolved in acetone from Nalgene:  60 ml/2oz LDPE drop dispenser bottle. I have used it for more than 5 years (stored inside) and have had not problems with evaporation, leakage or being unable to unscrew the bottle or open the top due to Butvar films. I do keep the bottle upright in a larger plastic container to catch any mishaps. I bought mine at REI in the camping section.

 

I suppose that this bottle also would work with other consolidants/solvent combinations including those using ethyl alcohol. See chart for plastic containers and chemical/solvent compatibilities: http://www.shepherd.edu/wordpress-1/wp-content/uploads/2016/04/chemical_compatibility_for_nalgene_containers.pdf

 

Note that LDPE containers are not recommended for storing acetone at higher temperatures: 50 deg C. I have had no problems storing acetone (and dilute HCl) at room temperatures at less than 90 deg F.

 

For a great source of small quantities of consolidants to use in this bottle see my post:

I have been using these lately and they work pretty well up to a certain viscosity I assume anyway.

Do remember wash bottles sorta act like thermometers particularly with volatile chemicals. Warmth will push acetone or ethanol up the spout. Ask me how I know....  

 

i use a syringe and needle and don’t have any issues with 25% Paraloid in acetone reacting with the plastic

They certainly do, so make sure not leave on a windowsill or in the heat

The only problem with those is that they can develop horizontal cracks which of course causes leaks.

I prefer to apply my consolidant using a very fine painter's brush like this one.

 

It is much slower but provides exquisite control of where the consolidant goes. Of course, if you need to consolidate a large area or bone, this doesn't work. I use a syringe for this.

I do the same.
