Hampton Research PEGRx 2, 10ml
Crystallization reagent kit designed to evaluate an array of polymers of varying molecular weight in a medium ionic strength environment in the presence of additives, salts, volatile organics and polyols versus a wide range of pH. Polymer reagents include Polyethylene glycols and Polyethylene glycol monomethyl ethers. The polymer molecular weight range between 200 and 20,000 is evaluated in a medium ionic strength formulation. Ten different buffers are used to span the range of pH between 3.5 and 9. The primary screen variables are polymer type, polymer molecular weight, pH and secondary reagents which include additives, salts, volatile organics and polyols. 10mlPlease note items from this supplier are non-returnable.
BEZWADA BIOMEDICAL LLC Dyed Poly(dioxanone) viscosity 1.0 to 2.0 dl/g, 5.0 GM
Poly(p-dioxanone) is prepared via ring-opening polymerization of p-dioxanone. It is the base material for the monofilament synthetic suture PDS, marketed by Ethicon Inc. Poly(p-dioxanone) has a low melting temperature of approximately 110 to 120oC and exhibits a low glass transition temperature of approximately -5 to -15oC. This material has crystallinity of approximately 30-45%. It is the low glass transition temperature of poly(p-dioxanone) and its ability to be crystallized, coupled with its biocompatibility, which resulted in its application as a monofilament suture and other absorbable devices that can be flexed without breaking. The PDS suture retains 50% of its initial breaking strength after 3 weeks and is absorbed within 6 months, providing an advantage over Dexon or other products for slow-healing wounds. The polymer is used in medical devices and 3 D printing.

BEZWADA BIOMEDICAL LLC Poly(L-lactide-co-caprolactone), L-lactide:caprolactone 60:40,viscosity 1.0 to 2.0 dl/g, 5.0 GM
The presence of caprolactone repeat units in the copolymer reduces the degree of close packing between lactide repeat units leaving the polymer with nice elastic properties while maintaining a relatively slow degradation profile. This allows PLA-PCL copolymers to be used in drug delivery and medical device coating applications for controlled release applications. Given below is the collection of our Caprolactone/L-Lactide copolymers. The polymers are used in medical device, drug delivery and 3D printing.
