Used cuvettes, quartz or optical glass

24.80153.60 ex. | 30.01 inc.

We offer used cuvettes of quartz or optical glass which can be used for spectroscopic analysis.  They can be used in spectrophotometers, luminometers and fluorimeters.  Our stock ranges from semi-micro size cuvettes for sample volumes between 1.5mL and 3.0mL, to macro cuvettes for samples larger than 2.5mL until ultra-micro sized cuvettes for sample volumes as small as 70µL.

Quartz consists exclusively of silicon dioxide (SiO2) and shows remarkable properties:

  • Quartz displays a high UV transmission, down to well below 200 nm.
  • The thermal expansion of quartz is low, being 6 x 10-7K-1between 20 °C and 300 °C.
  • Quartz is chemically very resistant and maintains its shape, even up to 1000 °C.
  • More than 80% transmission between 200 nm and 2500 nm for an empty cell.
  • QS is the logo which indicates that Quartz of the highest purity and homogeneity is used.

Optical glass is made from exceptionally pure raw materials, which gives an improved transmission in the near ultraviolet range.
Common criteria for all types of optical glass are:

  • That the cells made from it are used in the visible range of the spectrum.
  • That the glasses are characterized by low values of refractive index and dispersion.
  • That they display good resistance to chemicals.
  • More than 80% transmission between 320 nm and 2500 nm for an empty cell.
  • OS is the identification logo which referred to the Optical Glass.

All our used cuvettes are checked for any cracks or other damage prior to offering them for sale. The offered items are specified by: Type, Light Path, Height and volume.

Product Description

Our used cuvettes can be applied to hold samples for spectroscopic analysis. Cuvettes are made from glass or different types of plastic. It can be used in spectrophotometers, luminometers and fluorimeters. Cuvettes are used in the visible range for colorimetric assays and the UV range for DNA, RNA, and protein analysis. Semi-micro size cuvettes are for sample volumes between 1.5mL and 3.0mL, macro cuvettes for samples larger than 2.5mL and ultra-micro sized cuvettes may be used with sample volumes as small as 70µL. Disposable plastic o glass can be used to prevent sample carry over. Consider sample type and compatibility with your laboratory’s model when selecting the appropriate cuvette

 

In general, we divide the glass materials that we use into two groups: quartz and optical glass.

Quartz consists exclusively of silicon dioxide (SiO2) and shows remarkable properties:

  • Quartz displays a high UV transmission, down to well below 200 nm.
  • The thermal expansion of quartz is extremely low, its coefficient of thermal expansion being 6 x 10-7K-1between 20 °C and 300 °C.
  • Quartz is chemically very resistant and maintains its shape, even at high temperatures up to approximately 1000 °C.
  • More than 80% transmission over a spectral range between 200 nm and 2500 nm for an empty cell.

QS is the identification logo which indicates that Quartz of the highest purity and homogeneity has been used for the window.

 

Optical glas is made from exceptionally pure raw materials, which gives an improved transmission in the near ultraviolet range.

Common criteria for all types of optical glass are:

  • that the cells made from it are used in the visible range of the spectrum.
  • that the glasses we use are characterized by relatively low values of refractive index and dispersion.
  • that they display good resistance to chemicals.
  • More than 80% transmission over a spectral range between 320 nm and 2500 nm for an empty cell.

OS is the identification logo which referred to the Optical Glass.

 

Our used cuvettes are checked for any sustained damage.

They are devided by: Type, Light Path, Height and volume.
