6 stuks normale mond paddestoel vloeibare cultuur deksel graan spuit teelt Mason Jar deksel met 0,2 micron PTFE spuit filter & 20 mm zelfgenezende injectiepoorten voor paddenstoelenteelt mycologie

Funktioniert absolut perfekt das beste Lid was ich jeh ausprobiert hab. ab und an sind die ein bisschen locker aber einmal kurz mitm Feuer ran dann passt es wieder. top qualität wär enur gut wenns günstiger wäre . Die Preise sind mehr als doppelt so hoch wie sie sein sollte deshalb kein erneuter kauf-

These lids melted and became unusable after being put in a pressure cooker for 90 minutes at 15psi, as is usual for mushroom cultivation. This is despite the listing stating they were ok to be used in this way.Very disappointing and a total waste of money.

Die Deckel sind gut und vertragen 90 minuten bei 15psi. Jedoch muss die Temperatur beobachtet werden. die Filter vertragen gute 120 celsius aber nicht heisser ansonsten können die "Plastik" teile schmelzen.

Passt gut und funktioniert!

I must have misread the description. When I bought these I read 90mm diameter. They don’t fit my Ball quart jars. Luckily I bought some pint jars at the same time and these lids do fit pints. I’m just starting out so I don’t need a whole quart of culture anyway, so this didn’t affect me too badly.The thread fit on pint jars is not exact. However, I think this is an issue with the glass threads on the jars as much as it is with these lids. I had to try each lid on a few different jars to get a well-matched fit. I would suggest making these lids split style, as they are available for the 86mm wide mouth jars. I’m buying the larger split style right now.I wish the Luer fitting for the filter was Luer LOCK. These are Luer taper. These are destined to go in my regular fridge, and a gentle knock might send the filter flying and contamination into the jar.
