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. General storage protocols and suggestions for our various products are listed below:

 

Product type	Storage Suggestion
Dispersed Nanoparticle products (ANxxx)	4-10 °C, protect from light. Do not freeze
Block Copolymers (AKxxx)	-20 °C, protect from moisture
PolyEsters (APxxx CBxxx)	-20 °C, protect from moisture
Monomers (AMxxx)	-20 °C, protect from moisture
Cationizable Polymers (ACxxx)	-20 °C, protect from moisture
Lipid Derivatives (ADxxx)	-20 °C, protect from moisture
Maleimides (certain AIxxx, AExxx)	-20 °C, protect from moisture and thiols
N-hydroxysuccinimide esters (certain AIxxx, AExxx)	-20 °C, protect from moisture and amines
Fluorescent Conjugates (AVxx)	-20 °C, protect from moisture and light
Poly(acrylates/acrylamides) (AOxxx)	5 to 20 °C, protect from light and moisture
Polyoxazoline Derivatives (AXxxx)	-20 °C, protect from moisture
Poly(urethanes) (AOxxx)	5 to 20 °C, protect from light and moisture
KitoPure	5 to 20 °C, protect from light and moisture
Flamma-Fluor Fluorescent dyes	Storage temperature specified on label. Protect from light
Aquagel Products	Room temperature storage is fine, protect from physical crushing
AKiNAfil Products	-20 °C, protect from moisture
NuPlon Resin	Room temperature storage is fine
RiPurpose Products	Room temperature storage is fine, protect from physical crushing

 

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

 

Most products will be flushed with Argon when packaged for shipping. It will say this on the label. This will protect the product under any conditions as long as the container remains closed and sealed.

 

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.
