Wide Mouth Jar Plastic Lid Plus Filter & Port

Save yourself the trouble of struggling to get those pesky metal jar lids off in front of your flow hood. We hand make each lid to ensure the highest quality possible. Our RVC hugh temp gasket comes extra thick to ensure the tightest possible seal around your syringe needle.

We use a .2-micron filter patch to allow airflow while making it physically impossible for bacteria to enter your jar. We’ve tested our lids for many cycles through the pressure cooker and still the adhesive has stood the test of time. Once you go with these lids, you’ll never go back to our cheaper competitors again.
