• Adjustable temperature operation from 35° to 135°C? • Interchangeable sample cells? • Simple solvent flushing? • A built-in chart recorder? That chorus of four "yeas" denotes the certain presence of a Hallikainen Model 1361 Automatic Osmometer in someone's lab. Only Model 1361 offers them all. Built-in cartridge heaters and insulation and interchangeable sample cells allow you to switch smoothly from 35° to 135°C operation within the same hour. A syringe-full of fresh solvent quickly restores membrane condition between readings in either temperature mode. The entire unit, with integral chart recorder, occupies only 12" χ 15" χ 13" on your bench.
Digital readouts display osmotic pressure to 0.01 cm over a 10-cm range within 10 minutes of sample injection. Repeatability averages better than ±0.02 cm of solvent head. You can read four concentrations and calculate a compound's number-average molecular weight from 5,000 to 500,000 in less than an hour. About the same time it would take you to carefully study the product brochure. Write for your copy today!
