t2 copy2

t2 Sport™

The t2 Sport is an inexpensive cuvette holder with a compact structure that will fit in nearly any UV/Vis spectrophotometer. It provides temperature control for single beam instruments or the sample beam in a dual beam instrument. Use it for normal temperature ranges of about -10 °C to 110 °C.

t2x2 Sport™

The t2x2 Sport combines two inexpensive, compact t2 cuvette holders for use in a dual-beam UV/Vis spectrophotometer, one for the sample and one for the reference. Each cuvette may be controlled independently of the other. Use the t2x2 Sport for normal temperature ranges of about -10 °C to 110 °C.

Versa 20™

The Versa 20 is a versatile cuvette holder for use in UV/Vis spectrophotometers. An optional windowed jacket is available for work at low temperatures, isolating the cuvette from the environment. The normal temperature range of the Versa 20 is -40 °C to +105 °C. An extended temperature option permits work from below -40 °C up to +150 °C.

91_qCHANGER6_Cary60 small

qCHANGER 6™

Increase productivity with the qCHANGER 6, providing temperature control and magnetic stirring for six cuvettes in a UV/Vis spectrophotometer. The qCHANGER 6 has a temperature range of -15 °C to +110 °C, and uniform, stepping motor-driven magnetic stirring with a range of 200 to 2000 rpm.

TLC-50 GENERIC

Luma 40™

The Luma 40 provides optical ports on all four sides of the cuvette and is used primarily for fluorescence measurements. An optional windowed jacket is available for work at low temperatures, isolating the cuvette from the environment. The normal temperature range of the Luma 40 is -40 °C to +105 °C. An extended temperature option permits work from below -40 °C all the way up to +150 °C.

Turret 4™

The Turret 4 provides uniform temperature and magnetic stirring for four cuvettes. It may be used as a four-position sample changer for absorbance or fluorescence measurements. The Turret 4 has a temperature range from about -15 °C to +105 °C.

68_turret 6-AP wht bkgrd

Turret 6™

The Turret 6 is a 6-position cuvette changer for absorbance or fluorescence measurements. A secondary housing around the turret permits gas purging around the cuvettes and makes it ideal for use in circular dichroism spectrometers. A fiber optic version provides lenses and fiber optic connections, permitting its use as the core of a high-throughput spectrometer.

prod_cd250_ap

CD 250™

The CD 250, with its cuvette-driven architecture, is ideal for a variety of forms of spectroscopy: UV/Vis, fluorescence, and circular dichroism. The CD 250uses an exchangeable cuvette carriage, and can therefore accommodate a wide variety of cuvette styles, films, plates and other samples. It is thus ideal for circular dichroism measurements that often depend on the use of cylindrical, square or rectangular cells of various path lengths. Use it in place of the Versa 20 in many UV/Vis spectrophotometers.

75_qpod 2e

qpod®

The qpod is a compact sample compartment with a temperature-controlled cuvette holder in the center. Four optical ports surround the cuvette holder and may be configured as needed with optics for many kinds of measurements. Use it for absorbance, fluorescence, or Raman spectroscopy, with or without the use of optical fibers.

81_FLASH 300

FLASH 300™

The FLASH 300 is a stand-alone temperature-controlled cuvette holder that is generally mounted on an optical breadboard, surrounded by optical components. It has vertical and horizontal position adjustments. The normal temperature range of the FLASH 300 is -40 °C to +105 °C. An extended temperature option permits work from below -40 °C all the way up to +150 °C. An optional windowed jacket is available for work at low temperatures, isolating the cuvette from the environment.

82_PAS 1010 (1)

PAS 1010

The PAS 1010 is a complete system for pulsed-laser photoacoustics, without the laser. The core of the system is a FLASH 300 cuvette holder outfitted for use with an ultrasonic transducer, with the temperature stability and precision required for this form of spectroscopy. The PAS 1010 provides optics, energy probes, a fast diode trigger, cuvette holder, transducer, preamp, data acquisition hardware and a digitizing oscilloscope. The components are linked together with software for data collection, processing and analysis.

86_Cuvette Carriages

Accessories

Numerous accessories are available for use with Quantum Northwest cuvette holders. These include software, water circulators, windowed jackets for isolating the cuvette from the ambient environment, optical slits for limiting light access, cuvette carriages for the CD 250, optics for the qpod and qpod 2e, and accessories for pulsed-laser photoacoustics.
