Matrix Bio-Gel agarose gel
Particle size range
Coarse 150–300 µm 50–100 mesh
Medium 75–150 µm 100–200 mesh
Fine 38–75 µm 200–400 mesh
Shipping medium Fully hydrated in water, with 0.05%
sodium azide added as a preservative.
Resistance
pH range 4–13
Maximum operating pressure 15 psi

Temperature range* 2–30 °C
Storage 4 °C to room temperature
* Note: Above this temperature range the gel softens and freezing causes
irreversible collapse of the gel structure and alteration of the exclusion
limit.
