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.

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, burgundy, 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.

Okay, it isn't the cheapest magnet in the warehouse - but we dragged John's 165 lb filing cabinet around the dock with this 4-7/8" x 1" x 3/4" ceramic magnet, we're rating it conservatively at 100 lbs of pull, and we think it's a bargain. It has a 6" bracket with mounting holes on 5-1/2" centers, plus a 1/2" ID eyehook bolted into the center of it. It's all set to troll the bottom of the lake next time your filing cabinet falls overboard.

There's a tool for everything. Think post-hole diggers for a model railroad layout. All right, all right. Think cork borers for all those solid corks and rubber stoppers in laboratories, the ones that need holes for glass and rubber tubing. Our each is a set of (3) 3-3/4" long brass tubes with sharpened ends and red-plastic T-handles. Diameters are 9/32", 7/32" and 5/32". They're nested on the 4-3/4" pin used to clear the plug from the tube.

Fearful of language barriers, some folks get anxious when they travel internationally. Not this fine red-alcohol glass thermometer. Whether its travels take it to Britannia or Madagascar, Appalachia or Moscow, it's always ready to tell the temperature in the local tongue. Working stateside? No problem: it reads 0° to 234° F, in 2° increments. On a junket across the pond? Again, the Passport Therm shines, reading -18° to 112° C in 1° increments.

Our fashion buyers are just back from the shows in Milan with these brand new, nice quality, 80% poly/20% cotton lab coats. These are Euro-sizes, which generally (and generously) match chest circumference. The 42 has 34-1/2" sleeves, and the 48 has 36". All are about 39" long, which means fingertip length or mid-thigh, depending on how long you are. Think men's small, large and XL. They're all five-button, with one breast pocket and two large side pockets and have no name or embroidery added. Notched lapels, no vent-just what all the best-dressed technicians are wearing this season.

Getting tired of buying them and trimming them and losing them? Get rid of wicks altogether with this nifty little alcohol burner with a copper capillary tube in place of a cotton wick. Burns 90ml of denatured alcohol and comes with a heat shield (packed inside the reservoir) and a burner cap. Don't forget to remove the little rubber plug - it's there to cover the holes in the copper tube when not in use. And this is lab equipment, so resist the temptation to use it under a chafing dish; initially, it flares up a tad more than is good for Swedish meatballs.
