Hey guys, Dave Sease asked me to make a calibration solution for his refractometer (he asked a few weeks ago and I finally actually got down to doing it).
I have made the solution as follows:
35 g NaCl into water with a total volume of 1 liter.
I believe that gives 35 parts per thousand, which corresponds to 1.025 on your refractometers, right?
Does anyone else want some of this solution?
I made 500 ml and I have dispensed it into 10 ml aliquots.
I am working down at the Coral Reef on the weekends now and I will bring it with me on Saturday/Sunday. I'll be there all day both days so if anyone wants a 10 ml tube of it, just come down and I'll give you one. I made these to the best of my ability and am hoping my calculations are accurate but I can't absolutely guarantee that they're perfect.
I'm not charging for them or anything. I just figured you guys might be interested to know how accurate your refractometers are!
