Storage Suggestions

Many of the products provided by PolySciTech are biodegradable and require careful handling to ensure quality. There is no single storage suggestion, due to the wide scope and breadth of our products.

It should be noted that these are the optimal conditions for long-term storage.

Allow frozen/refrigerated products to equilibrate to room temperature, preferably in a desiccator cabinet, prior to opening.

**Note that short excursions to higher temperatures during shipping or handling will not significantly affect product quality.  If product is received thawed, refrigerate or freeze as instructed above.

Shelf Life

As these products are novel, in most cases exact shelf-life determination is not readily available. When stored as directed, however, the products have an estimated shelf-life as follows:

• Block copolymers (AK***'s) and Polyesters (AP***'s): 10 years
• Reactive Intermediates (AI***'s), reactive PEG's (AE***'s), Fluorescent label polymers (AV***'s), Monomers (AM***): 5 years
• Others (AO***'s), Kitopure: Generally 10 years, but varies widely based on type.

Note these are general guidelines and exact shelf-life depends on product storage conditions and type.
