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.
Potato dextrose agar (PDA) is a common culture medium used in microbiology laboratories for the cultivation and maintenance of fungi, particularly filamentous fungi and yeasts. It consists of mashed potatoes, dextrose (a type of sugar), and agar, which solidifies the medium to provide a solid surface for fungal growth.
Some fungi perform exceptionally well on PDA medium as opposed to other mediums like MYPA.
Potato dextrose is much lighter in color than other mediums, making it easier to notice contamination while keeping vigor.
PDA plates are used for various purposes in microbiology, including:
Your order 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.
