Chemically treated paper strips to test for acid or base (alkaline)
solutions. Use the blue for acids, the red for bases. The more
sophisticated hydrion pH test paper strip indicates pH from 1 (bright red) to 14
(dark brown). Values in between can be read by comparing with a color
chart that comes with the strips. All have (100) strips of test paper
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.
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.
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.
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.
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.
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.
