My trusty refractometer has rusted out and the sample cover doesn't move any more. I'm planning to buy a new one but can't find our refractometer fluid.
Does anybody have some I can use to calibrate a new refractometer?
Let me ask mike the treasurer if we have any more.
I got my bottle of refractometer fluid from the new hobbyists workshop and I'm still using it to this day. Only holds like 50 mL but you only need like 3 drops to take a reading.
