They also highlight the issue of evaporative loss, which may result in artificially low particle size measurements. The new system\u2019s rapid cooling action and ability to maintain stable temperatures throughout the test help avoid this problem.<\/p>\n<p>Cascade impaction measures aerodynamic particle or droplet size, a key parameter for all inhaled products that ensures product consistency and broadly indicates deposition behaviour within the respiratory system. For devices such as nebulisers, which deliver the active ingredient as an aerosolised solution, evaporation during testing, caused by impactor related heat transfer, is an issue. Loss of solvent reduces droplet size, producing artificially low particle size measurements and compromising accurate characterisation of the device. Cooling the impactor to approximately 5\u00b0C is one of the most common ways around this problem.<\/p>\n<p>The NGI cooler comfortably accommodates the NGI, either closed or open, allowing testing in a temperature controlled environment. Rapid cooling ensures that test temperatures, user adjustable to as low as 3\u00b0C, are reached in less than 5 minutes; temperature stability is to within +\/-1.5\u00b0C. Large front and rear opening doors allow for easy access, with special access ports for the externally mounted device and pump tubing.<\/p>\n<p>For further information please visit <a href=\"http:\/\/www.copleyscientific.com\">www.copleyscientific.com<\/a><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-1950\" src=\"https:\/\/www.copleyscientific.com\/wp-content\/smush-webp\/2019\/12\/Screen-Shot-2019-12-12-at-16.15.42.png.webp\" alt=\"The NGI enclosed in the NGI Cooler \" \/><\/p>\n<p style=\"text-align: center;\"><strong>CAPTION<\/strong>: The NGI enclosed in the NGI Cooler<\/p>\n<h3>About Copley Scientific<\/h3>\n<p>Copley Scientific is recognised as the world\u2019s leading manufacturer of inhaler test equipment and is a major supplier of test equipment for pharmaceutical solid dosage forms, including tablet dissolution, disintegration, friability, hardness and powder testers.
