GPC/SEC Systems:

		Viscotek TDAmax - Integrated, temperature controlled GPC/SEC system The Viscotek TDAmax is a complete, temperature controlled, advanced, multidetector GPC/SEC system suitable for all macromolecular applications, particularly research.  It consists of three unique and complementary components – The Triple or Tetra Detector Array (TDA), the GPCmax integrated solvent and sample delivery module and the OmniSEC software.
		Viscotek 270max - Modular, ambient temperature GPC/SEC system The Viscotek 270max is a modular advanced multi detector detector system that operates at ambient temperature.  It is perfect for the routine full characterization of natural and synthetic polymers, copolymers and proteins.
		Viscotek RImax - Modular, conventional GPC/SEC system The Viscotek RImax is a modular, conventional calibration system.  It offers simple operation and full upgradeability to advanced detection.  Designed for routine GPC/SEC and teaching purposes.  Operates with the same powerful OmniSEC software as used in the advanced systems.

High temperature system for polyolefin analysis:

		Viscotek HT-GPC - For polyolefin analysis The Viscotek HT-GPC is a modular high temperature GPC system designed specifically and exclusively for the characterization of polyolefins at up to 160°C.
