Salinity calibration fluid

Awesome Dr. Put me down for 20-30 ml's, all i need, should last me a few years. This time i wont keep in garage and worry about evaporation. :hammer:

Maybe you can share at the October meeting.:o

Mass refractometer calibration meeting :D
 
Why wouldn't the manufacturer supply these with dropper style bottles which would equate in less evaporation and longer lifespan. Maybe it's just the brand I bought not sure.
