Blowing my mind here Myc!
I usually make a half batch cause I rarely need 50 half pint agar jars at any one time. This nugget of myco gold could save a bunch of time for me.
EDIT: Upon thinking about this a bit more, I wonder if this method would be smart to employ using half pint jars that have been sitting around on a shelf. It is much easier for my mind to compute using this method for a sleeve of new sterile plastic plates.
What are your thoughts Myc?
I'm not sure if I completely follow but I will attempt a guess:
You're asking if you could pour say......50 half-pint jars as "plates" for future use?
I have studied this type of storage.
The agar, when poured in small amounts and stored long-term, seems to change state and become grainy and soupy.
I have tried several methods of storage:
Plates in the freezer - short term (less than one month) and they're OK. Longer than one month and they change state as noted above.
Plates in the refrigerator - about a month in the fridge is OK. Depending upon how thick you pour your plates, your mileage may vary (I use 8ccs/plate).
After a month in the fridge, the agar begins to dry. Once the agar dries enough, it becomes useless for fungal propagation purposes.
Plates just left out to sit - poured and stored in the original sterile sleeve. Without fail, these plates always contaminated (at least one or two in the stack) - the stack was thrown out and this method was abandoned.
When storing agar "bulk" in quart jars - take care when nearing the end of the batch. Best to use it up after there gets to be less than 1.5 inches or so. For some weird reason the agar changes state. When poured, it remains grainy and soupy in texture and is useless for fungal propagation.
I like to play with agar and have a few threads lingering around here somewhere showing some of my experiments in detail.
Here's how I do tissue syringes. Scroll down to post #24:
