The Autoclavable Disc Filters from North Spore are essential for maintaining aseptic conditions in mycology jar culture. These precision-engineered 0.3 micron filters provide a critical barrier against airborne contaminants, ensuring the integrity of your sterile environments.

Specifically designed for 'Wide Mouth' Mason Jar Lids, these synthetic filters create a secure, breathable seal when placed between the lid and metal band with pre-drilled holes. Their specialized sizing ensures a perfect fit, preventing bypass filtration.

Constructed from durable, synthetic materials, these filters are fully autoclavable, allowing for repeated sterilization and reliable long-term use in demanding laboratory settings. This feature contributes to sustainable and cost-effective cultivation practices.

Optimize your cultivation process by integrating these specialized filters into your setup.

Please note: Jar and lid are not included with the purchase of these disc filters.
