Facts About STYROS™ Stationary Phases:

Price comparison between STYROS™ chromatography columns and Mono Bead packed columns from GE Healthcare (former Pharmacia):

Thanks to you, our loyal and ever-growing customers, we have done it for 14 consecutives years.

The price of an 8 ml Mono Q or Mono S column was $4,299.00 in 2005 as compared to $2,950 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 100 mm long 4.6 mm ID columnn, to 100 mm long 10 mm ID column of similar resolution.

Separation of cell culture with a 4.6 x 100 mm STYROS™ HQ/XH column
( volume = 1.7 ml)
Flow rate 5 ml/ min (1,800 cm/hr of linear velocity)

Scale up of the same separation of cell culture with a
10 x 100 mm STYROS™ HQ/XP column (volume = 8 ml )
Flow rate 5 ml/ min (380 cm/hr of linear velocity)

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 having 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 columns ranging in ID from 0.25 mm to 20 mm, and lengths of 1 to 250 mm.
