Rotatable Quartz Ampoule/Tube Vacuum Sealer – QAVS-100
Introduction
The vacuum sealer is designed to seal material samples inside a quartz ampoule tube. This is done while the tube is under high vacuum, using an oxyhydrogen or other flammable gas to create the seal. With its unique vacuum valve, which features both a coarse adjustment knob and a fine tube knob, this system prevents material powders from being sucked into the vacuum pump. This design significantly extends the service life of both vacuum and molecular pumps.
By default, the system includes one tube adapter for 20 mm OD quartz tubes. The QAVS-100 supports quartz tubes with outside diameters ranging from 2.5mm to 45 mm. Standard adapters available in stock include sizes of 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, and 35 mm. The included 20 mm adapter can be replaced with any of the standard sizes at no additional cost, and you are welcome to Purchase Extra Standard Adapters if needed. Customized sizes can also be made upon request. The smallest outside diameter we have produced for a quartz tube is 2.5mm.
Features
