Caps for TrayCell
Path length mm:

Traditional spectrophotometrical analysis of nucleic acids is carried out in 10mm cuvettes. Modern drop analysis uses light paths of 1mm and 0.2mm and it is thus not necessary to dilute the sample. In applications with very high or very low DNA concentrations these light paths are often no longer sufficient. When using the TrayCell from Hellma Analytics simply adjust the light path by exchanging the cap. Cap with integrated mirror to change the light path.

Disposable cuvettes for spectroscopy, in optical-quality PS and UV grade PMMA with optical windows for optimum transmittance when using wavelengths from 340nm to 800nm (PS) and from 280nm to 800nm (PMMA). Moulding and quality control determine the reproducibility of cuvettes. Kartell cuvettes are strictly controlled and varations should be within the range ±1% absorption. This is the vital when batch analysis is being undertaken.

Type:
HELLMANEX® III
Cleaning:HELLMANEX® III is an alkaline liquid concentrate used for the highly effective cleaning of glass or silica cells and other sensitive optical components. Laboratory equipment made of glass, quartz, sapphire and porcelain can also be cleaned using the solution.Characteristics:Hellmanex® III significantly reduces the surface tension of water. The removal of dirt particles is also assured by the good wetting action of a Hellmanex® III aqueous solution, whilst its high emulsifying and dispersing capabilities prevent the re-deposition of the loosened particles. Special surface-active substances facilitate the residue-free rinsing of the optical components once they have been cleaned.Cleaning and Dilution:The optimal dilution depends on several factors, such as the hardness of the water, the degree and type of contamination, the temperature, etc. The use of demineralised water improves the cleaning characteristics.Available in 1.3kg PE-bottle.The following treatments have been proven at a concentration (vol%) 0.5 to 2 in practice.Temperature°CTime minutes20-25120-18030-3530-4050-60 (quartz only)10-1570-80 (quartz only) 5Hazardous Substance DataGHSSignal wordAchtungH-SatzH290, H315, H319, H335P-SatzP234, P261, P312, P332+P313, P403+P233, P405UNNR3266SDSLink

Cuvettes
A cuvette is a vessel with plane-parallel sides that is used for optical investigations (UV/VIS spectroscopy). Cuvettes are available in different qualities. They are usually made of glass or plastic. For wavelengths below 200 nm, cuvettes made of quartz glass are required. A simple cuvette consists only of 2 glass plates, without spacers and allows layer thicknesses in the micrometer range, without dilution and can be used for visual comparison of strongly light absorbing liquids such as blood, cosmetics or heavy fuel oil.
