Turret 4/PTI

Temperature-controlled four-position turret sample changer for a PTI Spectrofluorometer
Product Overview

Increase productivity with the Turret 4/PTI, a 4-position turret cuvette changer for a Photon Technology International (PTI) Spectrofluorometer. The Turret 4/PTI that provides rapid, precise temperature control from -15 °C to +110 °C for to up to four cuvettes. There are three optical ports around each cuvette with dry gas purging to minimize condensation when working at cold temperatures. Precise, stepper-motor-driven magnetic stirring is available in each cuvette ensuring that each sample in the turret is studied under nearly identical conditions. PTI provides sophisticated control for the Turret 400/PTI, including temperature ramping and temperature step functions. If your experiments require such control, please contact PTI.
