Price comparison between
STYROS™
chromatography columns and MONO Bead packed columns from Pharmacia:
|
|
Thanks to you, our loyal and overgrowing
customers, we have done it again for
11 years in a row.
Most of our
STYROS™
chromatography column
prices
have remained the same.

MONO Bead
packed column high prices have
continued to rise steadily
The price of an 8 ml
Mono Q or
Mono S column was in 2005 as
compared to $2,950.00 for a
STYROS™ column
equivalent.
A
20 ml STYROS™
column is still less expensive than a
MONO Bead
column sold in 1997. |

Scalability with
STYROS™
columns is seamless, from a 100 mm long 4.6 mm ID columns, to a 100 mm long
10 mm ID columns of similar resolution

STYROS™
is made of
highly crosslinked Poly (Styrene-divinylbenzene) as compared with low
crosslinked polymeric soft gels.
STYROS™
can routinely be used at 207 to 276 bar (2,000 to 3,000
psi). This provides the option of packing longer columns, to be used not only
with low pressure chromatography systems, but also with high pressure, high
performance systems for faster separation and quicker results.
OraChrom
offers packed columns ranging in ID from 0.25 mm to 20 mm, and lengths of 1 to 250
mm.
