With support from Sabic, TriForest Labware has developed a polycarbonate 3L
Fernbach flask that the company says is the first of its size made using the injection blow moulding process.
TriForest Labware, a moulder of laboratory equipment, has developed a polycarbonate 3L Fernbach flask that the company says is "virtually unbreakable" as a result of SABIC's Lexan HP grade.
Syed Rehan, VicePresident, TriForest Labware, said: "Without the exceptional properties provided by Lexan HP resin--optical clarity, impact resistance and the ability to be injection blow moulded--we would not have been able to make this 3L Fernbach flask."
Fifty-milliliter cultures of B7 cells were grown at 35[degrees]C in 500-ml Fernbach flasks. The cultures were kept unshaken to avoid cell division stress (Hellung-Larsen and Lyhne, 1992).
The cell suspension was divided into aliquots as follows: 50 ml in each of four 500-ml Fernbach flasks (a); 80 ml in each of four 250-ml Ehrlenmeyer flasks (b); 80 ml in each of four 100-ml Ehrlenmeyer flasks (c); and finally, four 100-ml Ehrlenmeyer flasks filled to the top with the cell suspension (d).
