Chemically treated paper strips to test for acid or base (alkaline) solutions. Use the blue for acids, the red for bases. The more sophisticated pH test paper strip indicates pH from 1 (bright red) to 14 (dark brown). Values in between can be read by comparing with a color chart that comes with the strips. All have (100) strips of test paper per vial.

Rejoice, we have finally found a source of reasonably priced borosilicate lab glassware. This is the kind of glass in the trade marked Pyrex(tm) and Kimax(tm) labware. The stuff you can put right over the flame of the Bunsen burner, or directly onto the hot plate. This stuff is imported from China, and is considered student grade, which is good enough for anything but the most exotic applications. We have beakers, test tubes, graduated cylinders and flasks. Compare the prices below and you will see that they are around half the U.S. equivalent. Call us for larger quantity prices.

Affordable, adaptable lab equipment for serious scientists with laughable budgets. The basic stand is heavy black metal 8" long x 5" wide x 1" high with a 19-1/2" x 3/8" dia support rod screwed into it. Position a beaker or bunsen burner on the stand and build the configuration you need above it. Both of the Burette clamps and the ring attach to the rod with thumbscrew clamps. The Burette clamps have wing nuts so they can be adjusted to any angle. The single clamp extends 4" from the rod, with rounded, uncoated, adjustable metal jaws with spring tension and a wing nut. The double clamp like it has rubber-coated jaws. The 3" metal support ring holds the 6" x 6" heavy-gauge steel-mesh burner screen with crimped edges. Nice, solid equipment at a rare price.

This is Philip’s new favorite toy, since he blasted a rocket so high over our parking lot that he lost sight of it (the rocket, not the parking lot). The Air Burst™ Rocket system has a 26” tall, air–powered tri–pod launcher made of plastic and rigid foam. A 65” long air hose connects it to any stand–up bike pump. After a few pumps, the air pressure bursts a replaceable booster disc in the launcher and sends a 10” x 3/4” dia rocket 250 to 1000 feet into the air. Wow! The system includes the launcher, (2) rockets, and (60) boosters (two different weights). Sending rockets out of sight, even if they usually come straight back down, is an ingenuous ploy for selling extra rockets. Our each is a pack of (2). And having extra rockets is an ingenuous ploy for selling extra booster discs. Our each is another bag of (60). No bicycle pump? The 18” black Tech Team pump blew majestically through a “double bozon” booster for us! It creates up to 120 lbs of pressure while most pumps will only generate 80 psi. It fits a Schrader (American) valve. Warning: The Air Burst™ Rocket is for ages 10 and up, with adult supervision. Don’t let us catch you out there without a kid!

We've never seen anything quite like these little clear glass vials, which means they must have myriad uses, particularly at this price. The large one is 1-3/4" tall x 15/16" dia with a shoulder and a 1/2" ID lipped mouth on the top, leading into a 1" deep conical cavity. The bottom has a 5/8" mouth, with an internal lip, and opens into a cavity around the little conical reservoir. So you can fill either end. Which would hold maybe a couple of ccs one way, or 1/4 oz the other way. The little one is the same, but is 1-9/16" tall x 5/8" dia and a 1/4" ID mouth on top, 7/16" on the bottom. We're thinking obscure lab experiments, or chimneys for streetlamps in model railroads. Or something.

Search for zlotys on the beach, or just be the first militaria collector on your block with a USSR-era Polish army surplus mine detector. (That's a Polski armia nadwy?ka möj wykrywacz, we think.) Comes complete with (8) feet of pipe (in 2-foot sections) for getting farther from the mines, a 5-foot cord on the headphones, a log-book, a canvas carrying pouch, and a small box wrench. The downside? It's battery operated (and may even come with one or two dead ones) but not by batteries in any size we recognize, so making it operable could be a challenge.
