Here’s a fine pair of nylon bristle brushes, just perfect for cleaning test tubes, aquarium filter tubes or your favorite long-necked soda bottle. The smaller brush is 8-1/2” long with a 1/2" dia. while the larger is 10-1/2” overall with a 1-3/8” dia. The bristle area for both is approx. 3-1/2” long.

Or pipettes, depending upon how you roll. These pipet fillers are chemical-resistant, 2-1/8” dia rubber with the traditional A, S & E valves. S is 7mm ID and E is 9mm ID. Squeeze A to evacuate the bulb, S to suck the liquid up, and E to release the liquid. Should be able to fill up to 25ml. Non-chemistry folks could just leave one in their bathroom and let visitors speculate about its purpose.

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.

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.

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.

But science teachers can't work without them. Experiment with this good-quality manual vacuum pump made of durable polychloroethylene plastic. Works with a pistol-grip action and pulls up to 2" Hg. Includes a 17" length of clear vinyl, 1/4" ID tubing, and a release valve.

Jumbo sized cork for all your corking needs. Bottles or crafts its the perfect size. 1-1/4" top x 1-1/16" bottom and 15/16" tall. Cork away!

Choose either the 25- or 100-slide selection of 3" x 1" prepared microscope slides from Celestron®, both in sturdy hinged wooden cases. The selections include a wide range of bacteria; plant, animal and human tissue; insect or reptilian specimens; and a list of each of the slides.

No lab is complete without a cone-shaped Bomex separatory funnel with ground glass stopper and petcock and this 100ml one is 14-1/2" overall. Is case you're wondering, and we sure were, these are used in liquid-liquid extractions to separate the components into a mixture of two different densities. Aren't you glad you asked? An excellent price for basic lab glassware.

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.

You pick from our clear glass vial collection, all with gasketed black-plastic screw caps. The small vials hold approx 2ml and measure 1-3/8” tall x 9/16” dia with a 9/32 (approx 7mm) ID. The larger vials hold approx 5ml and measure 2-1/4” tall x 19/32” dia with an 11/32” (7mm) ID.

A recipe from the Elizabethan Cable Food Network?

Poly Erlenmeyer. Sounds like a fun date from Dusseldorf, but it's really a 250ml polypropylene flask with a non-gasketed screw cap. Measures 6" tall x 3-3/8" dia at the bottom with a 1-1/8" ID mouth. And unlike you it's autoclavable.

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. Our child-size lab coats are white cotton polyester, 4-button and hip length, with notched lapels, one breast pocket and two side pockets. You pick size 4, 22" long from collar to hem; size 8/10, 26" long; and size 12/14, 28" long.

Mini scientists need appropriately sized lab equipment, and, what a coincidence, we have a Mini Duo Scope from My First Lab™ with your kid's name on it. It's two microscopes in one, and won Creative Child Magazine's 2015 Product of the Year Award. Has 40X, 100X and 400X magnification, top and bottom LED illumination, and includes more than (40) pieces and accessories, including brine shrimp eggs and yeast specimens. Ages 8 and up, and requires (2) AA batteries. Today, the Mini Duo. Tomorrow, the Large Hadron? Hey, it could happen.
