These jars are 1/2 pint plastic canning jars that can be used to make PF Tek jars. They can be autoclaved multiple times and are very durable. The jars are straight walled and the lids are white and ribbed for easy gripping. Since they are made of plastic they won’t break while autoclaving or if you happen to drop them.
You can use these to grow cakes with the PF Tek, sterilizing grain, LC or any media or substrate. You can ad 50% more PF substrate to these jars because they are taller and have a smaller top surface area, so that means you’ll get a better yield. 70mm lid. They are also lighter - which means you’ll pay less to ship them. 1 Jar and 1 lid.
