qCHANGER 6/8454

Six-position temperature-controlled linear cuvette changer for the Cary 8454 (or HP 8252 or Cary 8453) Diode Array System
Product Overview

Use the qCHANGER 6/8454 and your Diode Array System to measure the absorbance of six temperature controlled samples at once. The qCHANGER 6 provides rapid, precise temperature control from over a wide range of temperatures. Precise, stepper-motor-driven magnetic stirring under in each cuvette ensures that each sample in the turret is studied under nearly identical conditions. Program T-App can be used for control of sample changing, while using ChemStation simultaneously, but independently to collect absorbance data. The qCHANGER 6/8454 will also fit into earlier versions of this spectrophotometer, such as the Cary 8453 and the HP 8452, and is used in upgrades of the HP 8252 by Online Instrument Systems.
