LAB & SCHOOL

It looks as though it should be used for administering laudanum! A 30mL, 1-1/4" sq x 3" tall clear glass bottle, it has thick molded sides and a heavy lip: very antique in appearance. It is stoppered with a red(!) rubber stopper which is the squeeze bulb for the glass dropper tube inside. A real eye catcher, but give it a good wash please. It clearly is not sterile.

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.

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, fresh herbs or lab concoctions as you prefer. You get a mortar and pestle as a single order.

These clear plastic test tubes hold 10ml and measure 101mm (4") long x 16mm (5/8") dia and come with matching #5 corks. You'll receive a handy package of (10) which is enough for a ROY G. BIV optical display which includes the lesser-known colors of not-quite-right green, Monday-morning-blue and plaid. Made in USA.

You always need more filtering flasks eventually, so why not stock up? This borosilicate filtering flask has a 500ml capacity and is graduated in 50ml increments from 150ml up. Has a 9mm glass barb that’s 1" long, and a 33mm mouth. Use a #7 rubber stopper with it and get filtering, folks.

These blue glass dropper bottles are the color of the cold cream bottles that everybody's mother used when everybody's mother used cold cream. Measure 3-1/8" tall x 1-15/16" dia and hold (1) oz. Plastic safety dropper cap is 2-3/8" tall and marked at 0.4 and 0.8ml.

This funnel looks delicate, but it's borosilicate so heat won't hurt it. The tough little glass funnel has a 75mm (approx 3") ID mouth and an 80mm long neck with a 6mm ID fluted outlet. No markings.

You pick small, medium or large borosilicate reagent bottles, all with ground glass stopper. Small is 60ml, 3-5/8" tall x 1-5/8" dia with a 7/8" long neck and a 1/2" ID mouth. Medium is 125ml, 4-3/4" tall x 2-1/8" dia with a 1" tall neck and an 11/16" ID mouth. Large is 250ml, 5-3/8" tall x 2-3/4" dia with a 1" long neck and a nearly 3/4" ID mouth. Made in India.

This blue plastic test-tube rack measures approx 8" long x 2-1/2" wide x 3-1/4" tall with (6) holes for full tubes, the end ones at 1-1/16" / 27mm dia and the others at 3/4" / 19mm. In front of these are (6) pegs for clean inverted tubes.

A great find: sterile plastic petri dishes, 90mm dia x 15mm deep, with a loose fitting lid. Great for growing cultures for your science fair experiments, as individual pancake storage cases or for mixing paint. Our each is (25) dishes and lids in a sealed, sterile package.

So we're pricing these borosilicate boiling flasks to move quickly. We've got (3) sizes, all with slightly flattened bottoms, each with a single, discreet, capacity mark in white. While the actual physical size can vary slightly, the volume remains the same. The 1000ml flask is 9-5/8" tall OA x 5-5/8" dia with a 1-5/16" ID mouth, and a lip. Takes a #7 rubber stopper. The 500ml flask is 6-7/8" tall OA x 4-1/8" dia with a 1-3/16" ID mouth, and a lip. Takes a #6-1/2 rubber stopper, but a #7 will work. The 250ml flask is 6-1/8" tall OA x 3-3/8" dia with a 1-1/32" ID mouth, and a lip. Takes a #5-1/2 rubber stopper, but a #6 will do the job.

Grow your own bacteria with this lab kit from EduSci. You get (3) sealed sterile Petri dishes plus a 1/8-oz bag of agar and instructions for use. Bonus: they teach you that agar is pronounced like jogger without the j.

A clear-glass, heat-resistant, volumetric flask with a ground glass neck and mating glass stoppers. These flasks are calibrated either at 500ml or 1000ml depending on which size you need. Both are around 12" tall. Not into lab work? Try it for techie salad dressings! Ain't surplus cool?

Distillation made heuristic. Nothing explains a process like a little hands-on experience, and this laboratory distillation kit is for showing instead of telling. Includes a 300mm Liebig condenser, Kjeldahl distilling column with 50mm dia bulb and rubber stoppers, 500ml Bomex boiling flask with 8" iron tripod, 2-foot lab stand/base with a single burette clamp, 500ml graduated Erlenmeyer flask and a 6" square of ceramic-coated wire gauze. You add some 1/4" ID tubing for the Liebig ports. Includes good directions for distilling ethanol and acetic acid.

Hard polypropylene beakers, milky white with a fine pouring spout. No good for flames, but great for low-temp lab applications. Also useful in the kitchen, the garage, or (the big one especially) as a plant watering can.

And a pestle to match. This 900ml, large-capacity mortar and pestle set is made for the lab but would also be proud to serve in your kitchen. (Call it the Guac Pot.) Mortar measures 6-1/4” across x 3-3/4” tall with a 7-1/2” long pestle with a 1-7/8” dia head, big enough to pestle anything into submission.

Polypropylene beakers times five. The nesting set includes a 50ml (marked in 5ml increments) beaker 2-1/8" tall x 2", a 100ml (5ml incr) 2-3/8" x 2-3/8", a 250ml (10ml incr) 3-7/8" x 3-1/4", a 500ml (10ml incr) 4-5/8"x 4", and a 1000ml (25ml incr) 5-3/4" x 4-7/8", all with lips and pouring spouts.

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 a1/4” ID mouth on top, 7/16” on the bottom. We’re thinking obscure lab experiments, or chimneys for streetlamps in model railroads. Or something.
