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.
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.
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.

Has a 3/16" ID tip and measures 8-1/4" long with a 2-3/8" dia, assorted colored, bulb. Get creative and think outside the box. You'll get a package of (3).
Almost big enough to pick up mortals: 10" long, 15/16" wide, with a mouth that rests open at 1-3/16". Stainless steel, non-magnetic tip, with a smooth, ungrooved tip that's .046" wide. Good for giant splinters, crafts, jewelry, electronics, or sushi.
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 400mL one has graduations in 50mL increments and the larger 1000mL one in 100mL increments with numeric markings every 100mL or 200mL accordingly; both with more room before you have to worry about spilling. Not intended for serious lab use as the volumes are approximates. Remember to ask for 236.5ml of coffee the next time you visit your favorite diner.
On a slightly convex aluminum plate, with small mounting holes top and bottom. Our glass alcohol thermometer measures between -30° and 230°F in 2° increments and between -30° and 110°C in 1° increments. The unit measures 6-1/2" x 1-1/16" with a 4-3/4" long element. Made for the laboratory, but nicely readable and able to hang on your wall without looking like part of a weather station.
