Sample Holders To date, Quantum Northwest sample holders have been used in instruments from at least the following manufacturers: PTI, Olis, Varian, Applied Photophysics, Shimadzu, ISS, Edinburgh Instruments, Hi Tech, Cary, PerkinElmer, Ocean Optics, SLM, JY Horiba, Spex, Aminco Bowman, Beckman, Hewlett Packard, Agilent, Chromex, Bomem and Quantum Northwest.
	TLC 40: Temperature-Controlled Cuvette Holder for UV/Vis - The TLC 40™ is a temperature-controlled cuvette holder with magnetic stirring and two open windows for spectrophotometry.
	TLC 42: Dual Temperature-Controlled Cuvette Holder for UV/Vis - The TLC 42™ provides independent temperature control and magnetic stirring to both the sample and reference cuvettes in a dual-beam spectrophotometer.
	TLC 50: Temperature-Controlled Cuvette Holder - The TLC 50™ is a temperature-controlled cuvette holder with magnetic stirring and four open windows for fluorescence.
	qpod: Fiber Optic Spectroscopy - The qpod™ is a versatile temperature-controlled sample holder for fiber optic spectroscopy, particularly useful for absorbance and fluorescence measurements.
	CD 250: Temperature Control for Circular Dichroism - The CD 250™ is a temperature-controlled cuvette holder for circular dichroism measurements that may be used with a variety of different cuvette types, including short path length cells.
	FLASH 200: Cuvette Holder for Laser Excitation - The FLASH 200™ is a temperature-controlled cuvette holder for pump-probe, fluorescence, flash photolysis or other laser-based optical experiments. An optional transducer mount is available for pulsed-laser photoacoustics.
	FLASH 300: New Cuvette Holder for Laser Excitation - The FLASH 300™ is a new cuvette holder for laser-based optical experiments. It differs from the FLASH 300 in two main ways. The adjustable height of the cuvette is much lower for easier use with lower laser beams. The top is also flattened to permit greater angular optical access to the cuvette.
	TURRET 400: Peltier-Controlled 4-Position Turret - This turret uses a powerful stepping motor drive for rapid position changes, variable speed magnetic stirring for each cuvette and dry gas ports under each of the 12 exposed cuvette windows.
	LC 600: Six-Position Linear Changer – This linear changer has Peltier temperature control, magnetic stirring under each cuvette and a dry gas purge to reduce condensation.  Use it for absorbance measurements.
