Please don't pop these little glass DCX beauties in your mouth. Sure, they're shaped like zinc tablets or miniature communion wafers - thin, 14mm dia - but they'll do you no good inside; probably even cause you harm. Instead, utilize their 48.3mm focal lengths for all classroom projects, or combine these with other lenses to build binoculars, magnifiers, microscopes and telescopes.

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.

Glass beads, 0.055" diameter!! They are German and are the kind you glue on stuff to make it sparkle or reflective--not the kind with holes. At our price you could do layers in little bottles for really cool thingums!! We have 'em in clear and a whole host of colors. Craft stores sell tubes of these beads for a ruinous $4.00 per tube or about $3.35 per oz.. Well, we don't have the tube so you are going to get a baggie, but you only have to pay $1.00 per oz so jump up and down and clap your hands over such a great deal!! The only thing left is to choose what you need. In case you can't do that, we offer an assortment of (10) packages which will include clear plus at least six (6) different colors.

What can you do with a thin aluminum tube? The question should be what can’t you do with a thin aluminum tube. It's flexible, it's thin, it's aluminum, it comes in a variety of lengths and thicknesses. What it's for is up to you. Here are the specs: #27529 is 10 feet long,.044” OD, .040” ID. #27416 is just 3–1/2” long, .048” OD, .042”" ID.

One wiseacre assumed we meant any package leaving our shipping room that once had a glass object in it. That is a malicious rumor. . . Ground glass is thin plate glass, the surface of which has been physically ground or acid-etched to create a grainy, grayish, opaque surface. Use it to produce an image from a lens or lens system. Even a simple magnifier, held between the ground glass and, say, a window, will produce an image of the window scene on the ground glass. Ground glass has another magical property: it is opaque to any object viewed at a distance, but not if that object is in direct contact with the glass surface. A necessary element of your optical education. #2728 (square) is 2"sq x 1/32" thick. #2610 (rectangular) is 3-1/2" x 4-3/8" x 1/16" thick.

These are really geared reduction motors, but much smaller and of lower power. Often used to operate cams and switches in electrical circuits, or to drive displays, they can generally be operated in continuous applications if not heavily loaded. Most are about 2" dia. x 1-1/2" thick. Remember CW means “Clockwise” and CCW “Counter–clockwise,” looking at the shaft.

Hemostats are the clamplike devices dangling from veins and arteries in melodramatic operating scenes. Our particular collection are Pakistani surgical-grade instruments made of magnetic stainless steel. As such we rate them pretty good, but not fantastic. Hemostats look like little pliers. The jaws are relatively fine, with rounded tips. The inside faces are lightly serrated to get a grip on tubing or body plumbing. And the handles are much longer than the jaws. Now the heavenly part. Great hobby clamps that can be worked into small areas. Fine heat sinks for electronics. Good hook extractors for trout fisherpeople. Excellent tubing clamps for flow-sensitive chemistry experiments. Sizes are approximate length.

Zillions of little bottles. Renegades from a pharmaceutical company, leftover unfilled from runs of exotic we-know-not-what. We have divided them into three basic shapes: A, Narrow Mouth, h (Narr Mo) have a 10mm dia. x 4mm long neck on top of a squarish shoulder, a 13mm dia. 3mm rim and a 7mm dia. opening; B, Wide Mouth, (Wide Mo) have a 16mm dia. x 4mm long neck on top of a squarish shoulder, a 19mm dia. x 3mm rim and a 12 or 13mm dia opening; C, Sloped Shoulder, (Sl Sh) have roughly 5-6mm long neck that tapers from the soft shoulder to 15mm dia, with a 19mm dia x 3mm rim and a 12-13mm dia. opening. Height refers to height overall, and dia. to the body dia. in the table below. Great items for the doll house (for kids old enough not to swallow them), to hold tiny wild flowers, for decorative art work, individual cruets, or just to hold and marvel at. All quite sturdy glass. In the real world, you would pay from $75 (smallest) to $225 (biggest) for 288 of these, which is the smallest quantity you could get!! Narrow mouth bottles take a #00 cork. (Our part number 88746) Wide mouth and sloped shoulder bottles take a #3 cork. (Our item number 88748)

We have a number of battery holders, constantly changing in detail. They may be plastic, they may be metal. They all have either simple short wire leads or connection points. In all cases, they hold a number of batteries and connect them internally in series. The table shows the number and type of batteries held, the final voltage, material, lead type and price.
