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!

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.

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) For those who can't make up their minds we offer an assortment of (10) bottles, with at least (5) different ones from the table below.

Eye dropper, tongue dropper, test tube dropper, petri dish dropper, anywhere dropper. Use this 3" glass dropper, with a rubber squeeze bulb to drop small amounts of liquid wherever you think they should go. You will have to measure by counting drops, though, because there are no markings on it. Also, it is called "3" because that is about how long the glass tube is. Overall, it is 4" long.

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.
