Clip this little lighted scope onto your smart phone and use the phone's zoom feature to show images (and take photos) up to 30X magnification. Our Optics Guru Paul says it has no business working this well for six bucks. Measures 2-5/8" x 1-1/4" and comes with (3) replaceable button-cell batteries for the light.
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.
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.
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
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 or lab concoctions as you prefer.
You get a mortar and pestle as a single order.
Rejoice, we have finally found a source of reasonably priced
borosilicate lab glassware. This is the kind of glass in the trade
marked Pyrex(tm) and Kimax(tm) labware. The stuff you can put right over
the flame of the Bunsen burner, or directly onto the hot plate. This
stuff is imported from China, and is considered student grade, which is
good enough for anything but the most exotic applications. We have
beakers, test tubes, graduated cylinders and flasks. Compare the prices
below and you will see that they are around half the U.S. equivalent.
Call us for larger quantity prices.
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.
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.
