1000ml Autoclavable Polypropylene Bottle – Full-Bore Wide-Mouth, Freezer-Safe with Vented Lid for Mycology, Labs or Home use
🔬 The Full-Bore, Zero-Waste Lab and Mycology Solution
The 1000ml Autoclavable Polypropylene (PP) Bottle is the definitive “old reliable” for lab and mycology work. Designed for maximum efficiency, this bottle features a full-bore, straight-sided 100mm wide-mouth design. Unlike standard jars with tapered necks, the zero-taper geometry ensures no residue gets stuck and makes scooping grain spawn or media effortless.
This is a specialized Freezer-Safe vessel, manufactured from thick, transparent virgin polypropylene. It is engineered to withstand extreme temperature transitions—from long-term culture preservation at -80°C to high-pressure sterilization at 126°C (20 PSI).
The Vented / Flush-Joint Advantage: The bottle features a full-bore, non-sealing screw cap with a coarse thread for easy removal or one-handed “popping” of the lid. This flush-joint design acts as a natural vent, allowing for safe pressure equalization during the autoclave cycle or deep-freezing. This prevents the “hydro-lock” or wall-collapse common in sealed bio-jars and allows for natural gas exchange, similar to a Petri dish.
Why This Bottle is Essential:
-
Transparent Visibility: Monitor mycelium growth or sediment levels without opening the vessel.
-
Industrial Durability: Impact-resistant and chemical-proof for years of repeated laboratory use.
-
Ecosystem Integration: The primary vessel for our Reusable Petri Dish Kit and ideal for breathable storage of VitaVermi BAM!
-
Cost-Effective: Handles repeated autoclaving, saving the expense of disposable containers.

STS Notes:
- Always loosen the cap by a quarter-turn before autoclaving to allow for pressure venting.
- To use as a spawn jar, apply microporous tape or grafting film over the joint to prevent contaminant ingress during the shake.

Unbelievable! Tyvek cap kept my cultures sterile for 3 months—worth every rand! Especially as used well over 100 times and bottle still looks good as new…
