LABORATORY MEDICINE • JULY 1971 Automatic digital osmometer The Osmette freezing p o i n t osmometer is designed to perf o r m automatically entire osmolality d e t e r m i n a t i o n . The maker claims that as rapidly as 45 seconds f o l l o w i n g sample introduct i o n , final result is displayed d i g i tally on Nixie tube panel meter and is locked there until sample is removed. Noninteracting c o n trols are said to reduce calibrat i o n t i m e to five minutes or less. A c c o r d i n g to the manufacturer, Osmette A is capable of precision to ± 1 m O s m / k g . over a range of 0 to 3,000 m O s m / k g . The osm o m e t e r is made to handle both 2.0 and 0.2 m l . samples.—Precision Systems, Inc. Circle Reader Service Card No. G-45. Downloaded from http://labmed.oxfordjournals.org/ by guest on October 14, 2016 The ITLC Kit detects c o m m o n l y abused drugs w i t h t h i n layer chromatography, according to the manufacturer. It is designed to meet the need for a simple m e t h o d of d r u g analysis requiring little training to produce clear separations. The kit is also made to handle routine laboratory separations of serum lipids, steroids, and amino acids. The kit includes chromatography chamber, solvent saturations pads, chromatography d y e , ninhydrin spray reagent, sample spotting guide, 50 sheets silica gel m e d i u m , 25 sheets silicic acid m e d i u m , 25 sheets fluorescent m e d i u m , instruction manual, and a b o o k by F. C. Haer on chromatography.—Gelman Instrument Company. The p r o b l e m of adverse d r u g reactions has led to the development of Cybertek's d r u g metabolism index (DMI), applications for w h i c h are: predicting therapeutically effective dosage levels to avoid potential side effects prior to the initiation of d r u g therapy; m o n i t o r i n g periodically for the detection and prevention of d r u g interactions; screening of new hospital admissions to detect a d verse d r u g reactions; m o n i t o r i n g of o u t p a t i e n t s to d e t e r m i n e w h e t h e r prescribed course of d r u g therapy is being f o l l o w e d ; screening of pregnant w o m e n to prevent adverse effects in the n e w b o r n ; screening to determine effective dosage levels for new drugs; using as a general screen to identify persons w h o are taking or w h o have recently been exposed to a w i d e range of drugs and chemicals. The new index is a ratio of adrenal hormones and their metabolites w h i c h monitors the rate at w h i c h drugs are metabolized by a person. The c o m pany bases its D M I on the fact that the great majority of drugs are eliminated f r o m the body by metabolic reactions in the liver, and that the same group of e n zymes w h i c h metabolize drugs also result in the elimination of certain specific hormones and their metabolites in the urine. A c c o r d i n g to Cybertek, a single D M I system is capable of screening more than 1,000 samples per day.—Cybertek. Bacterial control cultures The Fleaker is a new type of laboratory container designed to do all the things flasks, beakers, funnels, and bottles d o . The borosilicate glass Fleaker features a w i d e m o u t h / n a r r o w neck design to facilitate p o u r i n g powders and liquids in or out. The closure is a c o m b i n a t i o n of a conventional rubber stopper and a polypropylene cap. The containers are stackable, the b o t t o m of one Fleaker nesting in the t o p of another. The stopper is a l o w sulfur g u m rubber. Packed in cartons of 10 bottles and caps, the Fleakers come in six sizes; n o m i nal volumes are 150 m l . , 300 m l . , 500 m l . , 800 m l . , 1,000 m l . , and 1,200 ml.—Spectrum Medical Industries, Inc.

Blood bank control programmer The O r t h o Blood Bank Control Programmer is a self-contained w o r k station for routine processing of patients and donors for b l o o d transfusion. The programmer is designed to permit the h a n d l i n g of six donors or patients, or combinations of the t w o and to provide for a f l o w of test procedures, standardization of test conditions, and self-contained controls. The control p r o grammer is the second phase of the O r t h o Blood Bank C o n t r o l Program. The first, a 24-page procedures chart, leads the t e c h n o l ogist through g r o u p i n g , t y p i n g , reverse g r o u p i n g , a n t i b o d y screening, c o m p a t i b i l i t y testing, and a n t i b o d y i d e n t i f i c a t i o n . — Ortho Diagnostics.

LABORATORY MEDICINE • JULY 1971 Downloaded from http://labmed.oxfordjournals.org/ by guest on October 14, 2016 Instead of flasks and beakers Bact-Chek Quality Control Set contains eight different viable organisms preserved in stable, single-use discs and is designed to provide reference cultures for immediate use in many key bacteriological quality control procedures. The system is said to detect deficiencies in or deterioration of media, reagents, stains and biochemical procedures. The introductory set contains one vial each of eight organisms; 30 discs in each vial. The gram-positive organisms are: Staphylococcus aureus, S. epidermidis, and S. pyogenes. The gram-negative organisms are: Enterobacter cloacae, Escherichia coli, Proteus vulgaris, Pseudomonas aeruginosa, and Salmonella typhimurium. Each disc contains f r o m 10 5 to 10 7 organisms.—Roche Diagnostics.
