New scrubber has no moving parts and is self-cleaning, nonclogging, and according to the manufacturer, does the purifying job entirely by centrifugal action upon the moving gas or vapor with a minimum pressure drop. I n operation, the contaminated gas or vapor enters the vessel and spreads out in the lower chamber where it is combined with the scrubbing liquid, which is either sprayed on the outside of the tuyère or fed into the base of its inner circumference. Jet action from its passage through the tuyère blades imparts a rotary motion to the gas which thoroughly mixes it with the scrubbing liquid and tends to throw the heavier liquid particles to the outside of

Laboratory Electrodialyzer
Extremely fine, powdery m a t e rials which cannot be tumbled or dropped without excessive dust losses can now be dried successfully with this new tilting t r a y dryer, according to the manufacturer. T h e rotating system of tilting t r a y s permits t h e product to slide slowly from the upper t r a y t o t h e next t r a y below, thus, transferring the product with a minimum of entrainment during its downward travel through the dryer.

"Don't let the lab coat fool you. I'm not a lab technician. I'm a glass man . . . fooled around with glassmakin' all my life. "That's why I kinda smile when guys tell me that heat-resistant glassware is so much stronger than regular lime glass. "In that drawin' up above, I'm showin' what happens when you get a little careless and drop a flask made of borosilicate, heatresistant glass. It breaks! Just like any ordinary lime glass flask. "If you're buyin' heat-resistant glassware because you're goin' to use it with an open flame, that's one thing. But, if you're buyin' borosilicate ware because it's stronger, let me make a suggestion. "Try the same experiment I did. Drop a flask made of boro silicate glass on the floor. Then drop a regular Doerr Diamond D Blue Line flask on the floor. If they both break . . . buy the least expensive of the two.

Pirani Vacuum Gage Has Low Zero Drift Single-station Pirani vacuum gage, designated Type GP-115, measures on two scales the total pressure of condensable vapors and permanent gases in a vacuum system. The high range scale reads from 0 to 2000 microns of mercury, with 50 microns in the lowest division. T h e low scale expands the 0- to 50- micron portion of the upper scale and is calibrated in units of 1 micron. Useful for activating an alarm or protective circuit and aiding in auto matic cycling of a vacuum system, the device has a contact meter to actuate an external circuit upon a change in pressure.
