We’ve never seen anything quite like these little clear glass vials, which means they must have myriad uses, particularly at this price. The large one is 1-3/4” tall x 15/16” dia with a shoulder and a 1/2” ID lipped mouth on the top, leading into a 1” deep conical cavity. The bottom has a 5/8” mouth, with an internal lip, and opens into a cavity around the little conical reservoir. So you can fill either end. Which would hold maybe a couple of ccs one way, or 1/4 oz the other way. The little one is the same, but is 1-9/16” tall x 5/8” dia and a 1/4” ID mouth on top, 7/16” on the bottom. We’re thinking obscure lab experiments, or chimneys for streetlamps in model railroads. Or something.

What's three feet tall and wears a white coat? A kid in a chemistry lab, and don't drink the sparkling water. Dress them right for everything from lab sciences to art projects.

You pick size 4, 22" long from collar to hem; size 8/10, 26" long; and size 12/14, 28" long.

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 a friendly orange and fit (13 mm) dia openings. The orange are 9/16" across the top, which has a dimple in the center, and 9/16" top to bottom. 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!

Hardened steel knife edges, self-aligning agate bearings, magnetic damping mechanism. Durable cast metal base for stability.

These 6” steel dissection probes have knurled handles above 1-1/4” long x very sharp 1/16” points. Ignore the “Oil Pick” name on the package. We don’t know what it means either, other than that it translates to “surplus bargain".

Our each is box of (100) round filter papers, 12.5cm (approx 4.92") dia x 0.15mm thick (#1 size). No lab? Think craft supplies, throw-away coasters, or little caps to keep the gnats out of your pina colada.

Stainless steel surgical scalpel size #22. Great for hobbies and crafts.

About 1/100 of this solid brass 100g cylindrical weight. Measures 1" dia x approx 15/16" tall with a 7/32" ID cup hook at the top. Pretty. Useful for calibrating scales. And accurate to within one percent, which is one reason for this great price, because if it hit 100g on the head every time, we'd be charging you a heck of a lot more.

Black rubber stoppers for all your unmet rubber-stopper-top needs. You pick the bored (for laboratory tubes or making shakers) or the unbored, if you need closure.

All have (100) strips of test paper per vial.

We have obtained a large number of real natural corks ranging across the popular sizes used in science labs to seal vessels (drill your own holes for glass tubing, etc), use as floats and as a great craft item. Or just use them to seal bottles that don't have closures or cry out for a decorative seal.
