About
To prevent samples from oxidizing, we have two vacuum sealers, silica dessicant packets and aluminum foil coated bags.
Mini-pack Torre Vacuum Sealer
Larger chamber, can accommodate 100mm cassettes of 150mm individual wafer trays.
Food Vacuum Sealer
Perfect for small wafer trays, very easy to use and fast.
Bags + Dessicant packets
We provide silica dessicant packets, which you should place inside your bag to absorb water.
Plastic bags are provided at various sizes. For short-term (eg. few-month) storage these will work. However water-vapor does diffuse through plastic over time (eg. months).
For long-term storage, it is recommended to use the Aluminum-coated bags, which block diffusion of water & oxygen. Combined with dessicant packets, this should provide a good long-term storage solution for wafers sensitive to atmospheric water (eg. with Aluminum-containing epitaxial layers).
