Good evening, I wish to store biodegradable hydrogels for a period of one month. How can I make a protocol exist? Thank you very much in advance.
Dear Rosali Maurate, please check this similar RG thread. My Regards

Hydrogels could be stored short-term (1–4 d) under moist conditions (i.e. storage without drying) without a substantial loss of properties. For extended storage (7–28 d), they could be stored either at −80 °C (moist condition) or vacuum drying (dry condition). https://iopscience.iop.org/article/10.1088/2053-1591/aa8e37/pdf
Unopened, HydroGel can be stored at room temperature and does not require special handling. Shelf life for unopened HydroGel can be up to 24 months or more. https://www.clearh2o.com/animal-research-products/faq/hydrogel-faq/

Thank you very much. Does it affect if the hydrogel is for agricultural application?
Hydrogels have been used widely for enhancing the water availability for plants, by increasing water holding characteristics of soil and growing media, application of hydrogel polymers may be a proper technique to enhance water and fertilizers use efficiencies. It can be stored at common room temperature. Basically it forming natural polymers include polysaccharides like as agarose, starch or alginate, and proteins like as collagen etc.

I'm also working on hydrogels. They can be stored at room temperature that depends on the properties of the backbone of the hydrogel.Otherwise, hydrogels required a medium for their degradation. But dessicator can be used for their storage to prevent their degradation.For protocol you can read my papers.
I store my synthetic hydrogels at room temperature or in the refrigerator (4 degrees Celsius). If I want to keep the hydrogel moist, I close the lid of the vial containing the hydrogel and put it in the refrigerator. But if maintaining humidity is not important, I dry the hydrogel at room temperature and keep it at room temperature for a long time (several months). To perform various tests, I reswell the hydrogel if necessary.
