Hydrometer A is 10" long and is for liquids denser than water, measuring specific gravity from 0.8 to 2.04 in increments of .02 and potential alcohol or Baume between -2 and 73 in increments of 1. It's calibrated to be used at an ambient temperature of 20°C/68°F. (Handy if you're fermenting your own happy juice at home.) Hydrometer B is 11-1/4" long and measures specific gravity from 0.7 to 1.0 in .001 increments and potential alcohol or Baume from 10 to 72 in increments of 1. Designed to be used at ambient temperatures of 15°C/59°F. There's a third scale in Chinese that probably measures the same things, but our Chinese is a little rusty. The jar (which is unmarked and would make a very slick big bud vase) is 50mm dia x 305mm tall with a 100mm dia base and will take a #10 rubber stopper (not included) if you feel the need to stopper it.

So you don't have a gas jet in the garage? You don't think Margie and Ted are old enough to handle the high temperatures of a Bunsen burner? Our alcohol lamps are the answer. They burn alcohol (available at the hardware store), and are hot enough to boil water, to soften glass tubing for bending, and to generate the chemical reactions generally called for in science projects. Lamp (B) is 3-1/8” tall x 2-11/16” square glass with a wick assembly that brings the whole to a height of 4-1/2".

93481 SPECIMEN CONTAINER |
Means "staining stand" or "color rack" in German, and we think it's some sort of lab gizmo, but in English it translates to a nice, heavy glass dish 8-5/8" x 5-7/8" x 2-1/8", with a 1/4" thick wall. It comes with an adjustable, rectangular metal frame, 6-1/2" to 11" x 2-1/2" x 3-1/8", that fits over it. The dish looks suitable to bake in to us, and carries the Assistent logo. It's certainly a good serving dish, and with a few rubber bands the rack could be a watercolor brush stand/cleaner. Or you could open a German staining lab.

Leave a specimen in a plastic cup? Me? With the world waiting out there to discredit me? Waiting to sneak an incriminating substance into my pure-as-the-driven-snow urine? Not on your life! I brought my own 50mL clear-plastic, round-bottomed test tube approx 6-1/2" x 1-1/16" OD. I brought its gasketed white screw cap with an attached tear-off seal that, once tightened, has to be broken to be reopened. The tube will be sealed. The tube will be tamperproof. The tube will be a little tricky to pee into....
