Poloxamers and Poloxamer Library:
ExtRx has the expertise and equipment to produce a library of
poloxamers (poloxamers with different molecular weight and
composition). Following family of poloxamers are available (with
limited molecular weight and composition range):
- Regular poloxamers (PEO-PPO-PEO)
- Reverse Poloxamers (PPO-PEO-PPO)
- Tetronics (PEO-PPO-EDA-PPO-PEO)
- Reverse Tetronics (PPO-PEO-EDA-PEO-PPO)
In addition to the standard range of molecular weight and
composition, we can produce custom poloxamers at per customer
These library of poloxamer compositions are available for research
There is significant interest in purified poloxamers for improved
physical and stability characteristics as well as for safety reasons.
ExtRx has the expertise and facility to purify commercial grade
poloxamers to high purity (significantly improved polydispersity and
unsaturation). Provide purified poloxamer samples to interested
large quantities of poloxamers:
While ExtRx's strength is to supply research quantities (up to 2 kgs
per batch) of specialty poloxamers, it also has supply agreements with
large chemical companies (local and overseas) that currently manufacture
and sell poloxamers. ExtRx can assist the client to get the right
poloxamers manufactured on time.
ExtRx maintains a supply of poloxamer samples from
various manufacturers worldwide. In addition to the specification
provided by the manufacturers, ExtRx included additional test data on
these samples that might be helpful to the clients to make more informed
decision when choosing their poloxamer supplier.
For research and diagnostic purposes, there is a need
for poloxamers end group modified with UV or Fluorescence active ends for
clients. We can also attach customer's molecule onto poloxamer ends.
ExtRx can also synthesize radioactive poloxamers for research purposes.
We recognize that it is important to ensure that the radioactive
poloxamer should be very similar to the cold material. We will provide
CoA to demonstrate that the equivalency of the radioactive poloxamer.
