Ampule Sealer Attachment Reduces Oxygen Level Inside
The Ampulmatic ampule sealer, originally developed to flame seal glass ampules used in environmental testing, can also be used in the food industry for long-term storage of food and beverage samples. The ampules in a carousel are indexed under an oxygen/propane flame and rotated to form a perfect air-tight seal. Addition of an inert gas purging attachment has made the machine useful to food manufacturers who preserve ampules for batch records, analysis and quality control. The attachment injects an inert gas into the ampule before it is sealed, reducing the oxygen level inside. It includes a timer, solenoid valve and gas injection head to purge the head space of the ampule with nitrogen or argon prior to sealing. Operation is completely automatic and can be adjusted to most ampule sizes. Purging the ampules with inert gas makes it possible to seal volatile compounds, as well as increase the stability of the sealed material by reducing oxidation. Carousel racks expand the range of sealable ampule sizes from 1 mL to 50 mL. Custom-designed carousels are also available.
