Lids are autoclavable, dishwasher-safe, and designed for hundreds of runs through the autoclave or pressure cooker. Lids and seals are phthalate-free, PVC-free, lead-free, BPA-free, reusable, and recyclable.
Each pack of 6 culture jar lids includes 10 filters and 10 injection ports.
*Glass jar is not included.
