Screw Compressor Clamp
Used to regulate flow through a flexible tube. The screw driven jaw can be accurately adjusted in any position from closed to fully open to allow you to get just the rate of flow you want. The swing-away bottom jaw design lets you install over already connected tubing. The jaw opens to a maximum of 7/8" high and is 15/16" wide. Made of nickel plated steel, all edges are rounded to avoid cutting the tubing.

Tempera Cakes
Not Tempura, tempera. Color things Dark Green or Burnt Sienna (sort of dark brick red) but don't eat these 1-7/8" sq x 3/8" thick, 2 oz cakes of dry paint. From Weber-Costello, they are called "Biggie" and sell for $2.00 in the big boys' catalogs. Don't you love surplus??

Rubber Stopper
Pat's been hanging around the medical supply house again. We now have a boatload of rubber stoppers, the kind you see on bottles of liquid medicine, crimped down with an aluminum collar. (Pat didn’t buy the aluminum collars.) The medicine is removed via a hypodermic needle through the stopper. The rubber stoppers come in blue or gray They are 3/4” across the top, 5/16” top to bottom, and fits a 1/2” (13 mm) dia opening. Why would you want them? Because they'll fit many of the small wide-mouth and slope-shouldered bottles in our Bottlemania listing. Pat's really good!

Chinex?
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.

Needle File Set
Miniature 5–1/2" steel needle files. They come in the usual assortment of flat, wedge, triangular, and round shapes, (10) in all. They seem to be pretty uniformly fine with none that we would call coarse. Made in China, they come in a vinyl carrying case that snaps shut. Not as classy as some of the sets we have seen in the $18.00 range, but perfectly serviceable for most applications. And at a third the price.

Mashers and Smashers
Porcelain mortars and pestles. Great heavy duty mortars, with sides that are easily 5/16" thick on the smaller ones, and up to 1/2" on the larger. The mortars are glazed outside, but rough inside, the better to grind, and have a pouring lip. The business ends of the pestles are unglazed, while the shafts are glazed. Very functional, very good looking!! So grind your own spices or lab concoctions as you prefer. You get a mortar and pestle as a single order.

Real Corks!!
We have obtained a large number of real natural corks, mostly surplus with a few fill-ins bought commercially. They range across the popular sizes used in science labs to seal vessels (drill your own holes for glass tubing, etc) and to use as floats. Or just use them to seal bottles that don't have closures or cry out for a decorative seal.

Think Brown
Three 0.6 fl ounce tubes of acrylic "artists color" by Craftint(r). That's paint. Brown only. Perfect if you paint Kodiak bears, Guernsey cows or St. Bernards. More of a challenge if you specialize in polar bears, Holsteins or Dalmatians.

Scope Your Stethos!!
Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgandy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.
