The EasiCal system for organic solvents consists of two different combs, each with ten detachable spatulas supporting a mixture of five polymer standards with MWs selected to provide equidistant calibration points for greater accuracy.

Supplier: VARIAN

The quickest and most convenient method to deliver an accurate 12 point column calibration for organic and aqueous GPC/SEC column calibration.

Supplier: VARIAN

Polystyrene standards for many organic solvents either for conventional GPC column calibration or for calibrating light scattering and viscosity detectors that provide equidistant calibration points for greater accuracy.
