Pipet-Buret Instrument A pipet-buret instrument for accur
ate dispensing and titration, the Digi-Pet, requires no calculating in use. A micrometer drive is coupled to a digital counter which gives quick, exceptionally accurate direct reading of the volume dispensed.

The Rota-Jet, an automatic 3-cycle washer-rinser for laboratory glassware, scrubs, cleans, and rinses with five pin-point perforated arms rotating at a high R.P.M. and jet-forced power. It is equipped with a "steam eliminator" operating principle that eliminates the need to invest in a steam hood. The cabinet is completely leak-proof and maintenance-free, being heliarc welded with "o"-ring seals on the windows. The cabinet is all stainless steel with "Vista-View" window for a clear view of the washing chamber at all times without disturbing the door. Cabinet size is 77" high, 32 " wide, and 37" deep. Forma Scientific, Inc., Box 649, Marietta, Ohio.

Vacuum Pumps
The Model 1405H is a two-stage, oil-sealed, mechanical vacuum pump capable of producing a vacuum of 0.05 micron. This is said to be the highest vacuum obtainable with this type pump. This model has a capacity of 33.4 liters per minute, while the Model 1405B with a higher capacity, 58 liters per minute, is capable of producing a vacuum of 0.1 micron. The Welch Scientific Co., 1515 Sedgwick St., Chicago 10, III. 428
YOUR FORMULA FOR
MIDGET PUMPS AND STIRRERS
. . . is very likely to come from Eastern. High eff iciency in centrifugal and pos i t i ve d i sp lacemen t pumps at mass production prices—versatility in variable speed stirrers—these are the elements which add up to the right combination of laboratory equipment.
Compact design and remarkab le pe r fo rmance make them adap tab le where space and portability are factors.
Semi-enclosed, totally-enclosed, or explosion-proof motors powered from 1/30 to 1/3 h.p. offer a range of performance characteristics up to 20 G.P.M. at 15 P.S.I. Choice of metals, currents and voltages.
Eastern Laboratory Stirrers are available for mixing small quantities of light liquids to ten gallons of viscous materials. Models available with non-sparking motors. Sizes are from 1/1000 to 1/15 HP. Mountings may be either screw clamp or ringstand.
