FAQ

Q.

Why doesn't Continuous Single Culture®–NX (CSCM-NX) and Continuous Single Culture®–NX Complete (CSCM-NXC) contain phenol red?

A.

Phenol red does not contribute to the performance of the culture medium and serves only as a visual indicator of pH (1). We recommend that CSCM, CSCM-C, and CSCM-NX, and CSCM-NXC be equilibrated in a CO2 incubator with verified pH measurements prior to use. We will continue to offer CSCM and CSCM-C with phenol red.
