The Graduate devotee knows the importance of plastic. To fill the need we offer these fine cylinders of the hard milky white polypropylene persuasion, to help you measure out your chemicals. With a large bases for stability and spouts for pouring, they are just like their glass cousins, except these are cheaper and not heat-resistant (each is marked 20° C ?!). The graduation increments and total volume are shown as increment/total in milliliters.

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.

Al Luebbers, our founder, collected glass. Not glass like you'd find on a knick-knack shelf, but optical glass. Lenses, prisms, reticles and filters, for example. Focus on the filters. Many of his filters came out of military surplus, and this is for-real stuff. We mean many are solid dyed optical glass, ground and polished to flatness standards that were probably excessive. Others are from the old days in photographic optics, and their standards were even tighter than your militaristic Uncle's. We've found that photographers, artists, and optical designers still have an occasional need for good glass filters, so we're making a list of some goodies. As always, don't be timid about calling for quotes on quantities. If we have 'em, we'll sell 'em. Just don't sell them back. Please!

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.

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)

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.

Our aluminum canisters with clear glass pull–off lids are cool. The smaller canisters are aluminum–colored, a set of (20) 1–1/4” dia x 3/4” deep in a 6–1/2” x 5–1/4” x 7/8” lightweight aluminum box with a hinged lid. When the box is shut, a layer of foam padding inside the lid presses down on the canisters, keeping them securely closed. If you need slightly larger canisters, and a cardboard box will work instead of a carrying case, try our colorful display of anodized tins. They are packaged in sets of (12) and come in great assorted colors and are 2” dia x 7/8” deep. Each is an ideal carrying case for paints, many different screws, or other sets of small items or quantities that must remain separate. Prices are per set.

Sacre Bleu! This wonderful glass container from Canada has (5) different salad dressing recipes printed tastefully on it - in French.

It will take a #9 rubber stopper or #22 cork - or seal the 1-1/2" ID mouth with your palm as you shake it. Very earthy. Very chic.

Neon strip cardboard spectacles with diffraction gratings as the lenses. You can see the regular world, but all light sources and bright objects appear in multiple rainbow hued images. The effect is a little as though the whole world were a giant hologram. Great stocking stuffer or birthday party item for grade school ages.
