They're called shower caps and such they are. But barring regulatory problems in your industry, we see no reason why they cannot serve as sanitary hair covers in any dry applications (restaurant, clean room) just as well. Our pkg(4) brings you a total of (24) adult size caps, all clear plastic with little colored lace-like patterns scattered about on them and an elastic band at the opening. Labeled re-usable, at our price you can afford to toss them out frequently.

A 2-1/4" dia x 2-1/4" tall translucent white plastic bottle has two openings. Top center is a standard screw-on removable thumb spray spritzer. Off center also on the top is a 7/16" dia hole that comes with a black rubber stopper. We believe the secondary hole is designed to receive the tube from your home still while you use the spritzer to lay a gentle mist of the vermouth over the gin of your martini. It holds 8 oz which should last through the lapsed time between fermentation cycles.

The more sophisticated 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 per vial.

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.

We have obtained a large number of real natural corks, mostly surplus with a few fill-ins bought commercially. They range across the popular sizes used in science labs to seal vessels (drill your own holes for glass tubing, etc) and to use as floats. Or just use them to seal bottles that don't have closures or cry out for a decorative seal.
