Please be advised that during the months of December through February, shipping agar plates can be particularly challenging due to environmental factors. When the temperature of the package exceeds 40°C, the plastic wrap or wax parafilm used for sealing may melt, shrink, or otherwise be compromised due to heat. This can increase the likelihood of contamination.
A bubble or condensation on any of the plates is not a cause for concern and does not affect the product’s quality.
If you encounter contamination, please send us a clear photo of the affected plates, along with the number of plates affected and your order number. A refund will be issued upon verification of the issue.
Please note that we are unable to offer replacements, as the same environmental conditions may lead to similar issues. We appreciate your understanding and cooperation during this period.
Pre-poured sterile Water Agar Petri Dishes (WA) Plates with parafilm also called non-nutrient agar
Uses- Wild mushroom and spore cloning, isolating very bad contamination cases to grow Slime mould.
Pros- Mycelium grows fairly fast compared to contamination, so it is easier to isolate them
Cons- Very slow-medium
Each mushroom has unique genetics; capturing its best attributes is a simple but valuable skill. If you have encountered a wild mushroom or are in love with a specific strain, these dishes are your best tool. WA is an efficient medium for mushroom tissue propagation. That is due to its low nutrient value, which reduces the chances of other contaminants from thriving. On the other hand, mushroom tissues will colonize the medium under the right procedures.
Moreover, this product is a powerful and simple educational tool for learning cloning techniques. We believe that cloning mushrooms is simpler than growing them. We encourage beginners to experiment with common mushrooms from the supermarket, such as the Portobello / White Button species, to learn to clone. In this way, when growing or foraging mushrooms, this skill will come in handy. We recommend using at least 5 WA plates for cloning the desired tissue. This will help purification and increase the chances of success.
Your purchase includes:
Plate Shelf Life and Storage
The optimal shelf life for plates is 30-45 days. Order plates as needed, as they cannot be stored indefinitely, even in their original packaging. While most plates can last for months, their ideal shelf life is 30 days.
Usage and Contamination
Plates may remain usable beyond 30 days if uncontaminated. If contamination occurs in one plate, it doesn’t affect others in the pack. Discard contaminated plates and use the rest as normal.
The presence of a bubble or condensation in any of the plates is not a cause for concern.
Long-term Storage
Extended storage may cause plates to lose moisture, becoming stiff and papery. Use plates only if they remain gelatinous and uncontaminated. Discard any that become stiff or papery, as they can no longer support organism growth.
Refund Policy
For damaged or contaminated plates upon delivery:
• Contact us within 30 days of the ORDER date
• Provide photos for refund requests
• No replacements are offered; only refunds
Storage Guidelines
Before inoculation:
• Store in a cool, dry place (e.g., cupboard)
• Avoid refrigeration to prevent condensation
• Place upside down to minimize condensation
After colonization:
• Refrigerate when at least 60% colonized
• Label (date and species) and put in zip-lock bags for storage
• It is best to keep it in the vegetable compartment of the fridge
Remember: The packaging sleeve is not a sterile seal. Proper storage is crucial for maintaining plate quality.
About the petri dish-
These dishes are made of clear polystyrene, allowing clarity while being disposable and durable. It is easy to stock and grip and has an anti-slip ring that offers stability.
Agar Plate features
Agar-Agar
Agar-Agar is extracted from various seaweeds, such as gracilaria and gelidium (It contains no animal ingredients. Due to Agar’s unique gel properties and stability, it is used as a firming and thickening agent for Petri dish experimentation.
