Product Description
Details
These glass jars with metal screw cap are a versatile addition to any home cultivation lab. The thick glass walls handle the pressure and heat of sterilization, while the metal screw cap creates a tight seal between batches.
Available sizes
- 230 ml — small batches, agar prep, spawn jars for PF Tek
- 346 ml — medium substrate cakes
- 440 ml — standard cake size, popular for PF Tek
- 1062 ml — larger spawn batches and bulk substrate prep
Sterilization
Fill the jar, screw the cap on loosely, and sterilize in a pressure cooker or autoclave. Always allow jars to cool slowly to room temperature before handling to avoid thermal shock.
What you can use them for
- PF Tek substrate cakes (vermiculite + brown rice flour)
- Spawn jars with grain or substrate mix
- Sterile storage of dry ingredients
- Agar plates and culture work (with separately purchased modified lids)
Reusable and durable
Both jar and cap are reusable. After each cycle, wash thoroughly and re-sterilize before the next use.
Note: this is a standard screw-cap glass jar, not a Mason-style jar with a separate ring and flat lid. Sold per piece — select size above.

Arrived in order, did their job perfectly and had no issue with sterilization. They don't have a neck, so it is very easy to remove the content and clean them (Posted on 12/5/2022)Rating - GOEDE KWALITEIT GLAS Review by ERWIN

IK kocht de 1 liter potten, zijn van goede kwaliteit en hittebestendig. Een nadeel, de 1 liter potten zijn niet conisch zodat ik ze niet kan gebruiken voor mijn mycelium in te kweken, de cake kan er niet uit gehaald worden. Ik moet mijn substraat eruit halen na sterilisatie om het over te plaatsen in liter bakje zodat er steeds kans op besmetting is. (Posted on 9/17/2022)Rating - Practical jars Review by Merlijn

the 230 ml jars are a handy size, and the best thing about them is that they don't have a tapered mouth, meaning your cakes slide out easily. Good quality overall. (Posted on 6/5/2021)Rating - Exactly as advertised Review by Mirko
