Cuvets

 

Details

Disposable cuvets have long replaced cuvets once normally made of glass. New plastics coupled with modern methods of production allow photometric measurement well into the UV range.

Ultra-precision molds with several cavities – one per cuvet – are used for producing ratiolab® Q-VETTES and ratiolab® CUVETTES under controlled room conditions. Thus, in any one injection molding run several cuvets are produced simultaneously. In order to prevent deviations in extinction coefficient values from occurring in any one run due to increased stray light, the cuvets are automatically sorted according to their numbered cavities of origin.

Each package shows the corresponding local production number of the cuvetts position in the net. So all cuvetts inside one styrofoam box are technical wise indentical. Any measurement done with those identical cuvetts insures a high accurancy.

Cuvets 

  • Q-VETTES

     

    Details

    The new generation of cuvets with clearly improved photometric properties. The optimized form and the small wall thickness of the cuvets provides increased heat transfer resulting in more constant sample temperatures during photometric measurements.

    • glass-clear polystyrene (PS)
    • applicable wavelength range 340 to 900 nm
    • very low variation of extinction values
    • excellent optical transmission range
    • cavity-sorted production
    • path length 10 mm
    • outer dimensions 12.5 x 12.5 x 45 mm
    • supplied in practical styrofoam racks: 100 netidentical cuvets in a styrofoam box with closable lid

  • cUVettes

     

    Details

    For photometric measurements even in the UV range 220 nm.

    Due to the special plastic material and the excellent manufacturing process the cuvets can also be used in photometric ranges reserved for UV glass cuvets in the past.

    • applicable wavelength range 220 to 900 nm
    • very low variation of extinction values
    • excellent optical transmission range
    • cavity-sorted production
    • path length 10 mm
    • outer dimensions 12.5 x 12.5 x 45 mm
    • supplied in practical styrofoam racks: 100 netidentical cuvets in a styrofoam box with a resealable cover




    Product

    qvettes

  • Cuvets of PMMA

     

    Details

    • cuvets of polymethylmethacrylate (PMMA)
    • applicable wavelength range 300 to 900 nm
    • very low variation of extinction values
    • excellent optical transmission range
    • path length 10 mm 
    • outer dimensions 12.5 x 12.5 x 45 mm
    • supplied in practical styrofoam racks: 100 netidentical cuvets in a styrofoam box with a resealable cover

    Details

    • resistant against polar solvents
    • applicable wavelength range 220 to 900 nm
    • very low variation of extinction values
    • excellent optical transmission range
    • cavity-sorted production
    • embossed areas aside the measuring fields reduces the risks of damaging the cuvette by the cuvette holder
    • path length 10 mm
    • outer dimensions 12.5 x 12.5 x 45 mm
    • supplied in practical styrofoam racks: 100 netidentical cuvets in a styrofoam box with a resealable cover

  • UV Micro Cuvets

     

    Details

    The new generation of cuvets with clearly improved photometric properties. The optimized form and the small wall thickness of the cuvets provides increased heat transfer resulting in more constant sample temperatures during photometric measurements.

    • application wavelength range 260 nm to 900 nm
    • suitable for measurings at 260 nm, 280 nm and within visible wavelength range
    • applicable with low volumes from 70 µl
    • path length 10 mm
    • outer dimensions 12.5 x 12.5 x 45 mm
    • two different center heights of 8.5 and 15 mm facilitate the application without any adaptor in all most commonly used spectro-photometers like Eppendorf® WPA, Analytik Jena, Biochrom and others
    • round caps 2812010 for safe closing and sample storage until -20°C
    • supplied in practical styrofoam racks: 100 netidentical cuvets in a styrofoam box with a resealable cover
