Vortex Autosampler
The Vortex autosampler is a significant development in automated sample preparation and delivery for DSV. It is an integrated autopreparation and autosampling device with high temperature capability and is designed to increase efficiency, enhance precision and promote operator safety.
The heated (up to 150ºC) multi-stirrer assembly features a stainless steel tray, capable of handling either 20 ml or 40 ml vials. Each vial position has its own magnetic stirring mechanism, delivering consistent and reproducible stirring action from vial-to-vial and eliminating variability due to the dissolution process.
Accessory syringe pumps are used to dispense solvent and deliver sample. Solvent and sample delivery, dissolution times, load/inject sequences and multi-stirrer control are software controlled, effectively removing the operator from the sample dissolution and delivery process.
When coupled with Viscotek's Relative Viscometer, the Vortex provides a complete, automated system for determination of solution viscosities.
Other automation options are:
The DSV Autosampler provide automated sample delivery, which frees the operator from manual sample introduction and allows unattended processing of a whole sample batch.

The Semi-Automated Sample Preparation (SASP) option assists operators in the preparation process by controlling the weighing and dispensing operations for DSV measurements.

Featured presentations and application notes:
Application communication: Intrinsic viscosity of polyethylene in TCB at 135°C The Y-501 Viscometer is an accurate, efficient replacement for the glass tubes traditionally used in polyethylene solution viscosity measurement. The high degree of automation increases the precision while decreasing the labour and solvent exposure.
Application communication: Dilute solution viscosity of polyethylene terephthalate (PET) Viscosity of PET in OCP (Orthochlorophenol) and in 60% phenol / 40% TCE (Trichloroethanol) are measured every 5.5 minute automatically using the DSV. Excellent results are reported for both solvents.
On-demand presentation: High Temperature Dilute Solution Viscometry This online recorded seminar gives an introduction to the Viscotek high temperature Dilute Solution Viscometry system.
