This digital instant-read lab thermometer measures 8-1/4" long total with a 5" long stainless-steel probe that's resistant to most chemicals. Has a removable cover with a pocket clip, on/off button, and C or F readings (-50 to +300C, -58 to +572F). Button-cell battery included.
Inside the lab, it's a standard translucent-white, LDPE-plastic wash bottle, 500ml/16oz, measuring 2-3/4" dia x 6-3/4 tall with a screwcap and a right-angle, 5/16" dia nozzle. Outside the lab, it's so pleasing to squeeze and squirt with that some of us keep them in the kitchen.
Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgundy, green and purple, but there may be other colors yet to be seen! A great discovery device whether for biology or other pursuits. Not of professional quality, but not just a toy.
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

is approx. 3-1/2” long.
Puns-R-Us. This white coffee mug has pi-Lingual printed on it, along with a bevy of geometric diagrams and equations, plus pi carried to 50 decimal places. Try not to use while eating a piece of pie, because there are some limits to what people will tolerate.
In the lab or kitchen, these clear borosilicate glass mugs have a handle and lip and remind you that science is part of your every day. The smaller one has 50-350ml graduations in 50ml increments and the larger one goes up to 900ml in 100ml increments, both with more room before you have to worry about spilling. Remember to ask for 236.5ml of coffee the next time you visit your favorite diner.
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.
Agar, it's not just a crossword puzzle answer. It's the medium of choice for growing bacteria, molds, etc., and just what you need if you're shopping for laboratory staples or for your next science-fair project. Melt the medium in a microwave, pour into a Petri dish, and allow to set before applying test material. Do not freeze, and after exposure or melting, store at the temperature on the label. Does approx. 10-12 petri dishes.
