Materials/ Surface Treatment

Materials

  

Exclusively high-grade polystyrene ans polyethylene terephthalate are used as raw materials for manufacturing our cell culture pruducts. Polystyrene (PS) is characterised
by its high clarity, which greatly simplifies the optical
control of cell growth in polystyrene flasks, tubes and
roller bottles.

Polyethylene terephthalate (PET) is used for manufacturing roller bottles, media bottles and membranes, due to its beneficial chemical, optical and mechanical properties.

The granules are homogenised at 240 to 290 °C and then further processed to high quality products by injection moulding.
Surface Treatment  
TC-Surface Treatment (Physical)
This treatment leads to polar groups, such as carboxy- and hydrocarboxy groups, being incorporated into the plastic surface, making it hydrophilic.
This significantly improves the adhesion of cells and the binding of proteinsto the plastic surface.
The surfaces of CELLSTAR® and CELLMASTER™ products are treated using this special physical method.
Biological Surface Treatment
Our CELLCOAT® products are treated with proteins of the extracellular matrix or with Poly-Lysines facilitating the growth of many cell types.
Polymer Modification
For the cultivation of fastidious cells or cells cultivated under restricted growth conditions Greiner Bio-One now offers the novel Advanced TC™ polymer modification. Based on the innovative technique the cell culture surface is modified to positively influence cellular features and functions.
