Expedite yout FREEZE-DRYING Ptoceétes! N o matter the extent of the freezedrying operations in your laboratory, you're certain to find T H E apparatus most suited for your procedures in Machlett's wide and diverse line. Rang­ ing from a 4 0 0 ml capacity all-glass unit to an 8 liter capacity stainless steel super unit with conveniently staggered drying ports, all of these apparatus are self-contained and d o not require the conventional dry ice chamber o r con­ denser. However trap can be used for added safety. While all of the stainless steel ap­ paratus can be autoclaved as a unit after use with infectious materials, the macro and super drying units hold enough dry ice and solvent for unattended over­ night operation. Their large inner cooling chambers also lend themselves readily to shell freezing.

NEWS ASTM Atlantic City Meeting T h e 58th annual meeting of t h e American Society for Testing Materials, to be held a t Atlantic City, N . J., J u n e 27 to J u l y 1, will include 32 technical sessions a n d about 50 meetings of committees and subcommittees. T h e annual M a r b u r g Lecture, established to honor t h e first secretary of t h e society, will be given J u n e 29 by Walter J. Hamburger, Fabric Research Labora­ tories, Boston, Mass., who will speak on " A Technology for t h e Analysis, Design, a n d Use of Textile Structures as Engineering Materials." T h e Gillett Memorial Lecture will be given by Fritz V. Lenel, Rensselaer Polytechnic Institute, Troy, Ν . Υ., on J u n e 28 on t h e subject of "Powder Metallurgy, New Techniques, Improved Properties, Wider U s e . " T h e meeting will include seven sym­ posia on impact testing, j u d g m e n t of factors in soil testing, high p u r i t y water corrosion, atmospheric corrosion of nonferrous metals, speed of testing, and metallic materials for service above 1600° F . Individual papers will cover soils, nonferrous metals, steel, tests of concrete, fatigue, and effect of t e m ­ perature. A panel discussion on pyrometric practice in elevated temperature testing will be sponsored b y t h e Joint A S T M - A S M E Committee on Effect of T e m p e r a t u r e on t h e Properties of Metals.
