Until now, I&#8217;ve been making up solutions for science kits in 2-liter Erlenmeyer flasks, 2-liter soft drink bottles, or gallon (3.8 L) jugs. But one of the solutions I need to make up is the Fertilizer concentrate part A for biology kits, which is supplied in 125 mL bottles. A gallon of Fertilizer A is sufficient for only 30 kits, and I need to make up sufficient for 90 kits. Rather than make up 3 gallons (~12 L) of that solution in separate 1-gallon batches, I decided to make up a single 3-gallon batch. That means I need a largish mixing vessel. Fortunately, I happen to have some 19-liter polypropylene beakers on hand, AKA 5-gallon buckets from Home Depot. They&#8217;re bright orange, granted, but they&#8217;re clean, sturdy, and chemically resistant.<br \/>\n<\/span><\/p>\n<p><span style=\"font-family: Arial;\">Unfortunately, they&#8217;re not graduated, but that&#8217;s easy enough to address. My shipping scales have one-gram accuracy and resolution up to 20 kilos, so I&#8217;ll simply tare an empty bucket, transfer 11,356 grams (3 gallons) of water to it, and use a permanent marker to draw a line at the 3-gallon level. Actually, I&#8217;ll probably just do the line at 12.5 liters and make up sufficient solution for 100 bottles rather than 90.<br \/>\n<\/span><\/p>\n<hr style=\"width: 65%; height: 3px; font-family: Arial;\" \/>\n","protected":false},"excerpt":{"rendered":"<p>08:37 &#8211; Friday the 13th falls on a Friday this month.\n<\/p>\n<p>Well, it&#8217;s finally happened.
