Features of Injection Ports & Gas Exchange Filters - 0.22 Micron (32 Count)
- Includes 32 self-healing injection ports with a diameter of 13mm for spore injections.
- Comprises 32 self-adhesive synthetic filters with a 0.22-micron rating and a 3/4" size for efficient gas exchange.
- Comes with a roll of 3M Micropore tape measuring 1/2".
- Ideal for creating lids for spawn and liquid culture jars.
Instructions: Easily create lids by using a high-speed drill with a 1/4" metal drill bit to make two holes in the lid. The filters and injection ports are designed to fit perfectly in 1/4" or 7mm holes. Place micropore tape under metal lids to prevent rust from coming into contact with the substrate.
- Autoclavable and reusable.
