Multi-purpose, ready-to-use scintillation cocktails for Liquid Scintillation Counting (LSC) of β radiators (e.g. 3H, 14C, 32P, 35S) in aqueous samples. NPE-free
The next generation ROTISZINT® Cocktails have been developed to replace nonylphenylethoxylates (NPE) with more user-friendly, sustainable reagents. In addition, these modern cocktails show even higher scintillation efficiency and higher sample holding capacity. ROTISZINT® cocktails are also biodegradable and pleasant to use due to their high flash point.
ROTISZINT® scintillation cocktails may be used in all biological, biochemical and chemical areas. Typical applications are, for instance, the measurement of cell culture supernatants, routine analysis, enzymatic or flow-count assays in the field of research, development or analytics.
The cocktails are according to Directive 2003/53/ECC of the European Parliament and Council
Wide excitation range between 190 and 370 nm
Emission maximum: 420-430 nm
Our modern ROTISZINT® cocktails contain the same reagents as primary and secondary scintillators that were used in ROTISZINT®Eco plus. Thus, neither the excitation nor the detection wavelength change for the application.
We also recommend to use the same scintillation protocol in the first approaches with one of the new ROTISZINT® cocktails as was previously used with the cocktail Eco plus (0016). In many cases, the parameters are directly transferable. If the scintillation results are not satisfactory at first, the sample quantity (the ratio sample/cocktail) can be readjusted.
The ROTISZINT®FlowCount cocktail is intended for use in Flow Scintillation Counting and has been formulated using alcohol ethoxylates, containing no NPE at all. It has been developed to work with most commonly encountered eluents, including gradients, used in Flow counting. ROTISZINT®FlowCount does not form gels, providing rapid and easy mixing.
Biodegradable.
Suitable for general eluents and aqueous/organic gradients, e.g. and water/methanol or water/acetonitrile gradients up to 2 : 1 ratio.
We recommend the use of ROTILABO®Dispensers.
Emissiemaximum | 420 nm |
The composition of the ROTISZINT® cocktails is modern and does not contain NPE (nonylphenylethoxylates, subject to REACH). The cocktails thus comply with the Directive 2003/53/EC of the European Parliament and Council.
NPE has been replaced by a combination of several reagents specifically adapted to the respective use. The cocktails can thus be used in a targeted manner and give very high counting yields.
All new ROTISZINT® cocktails are biodegradable. Due to the low vapour pressure of the solvent, there is no odour nuisance, the solution is difficult to ignite and economical in consumption. ROTISZINT® shows excellent quench resistance, good sample stability, no chemiluminescence and no diffusion through plastic vials.
The ROTISZINT® scintillation cocktails of the next generation are modern, versatile, ready-to-use scintillation cocktails for liquid scintillation (LSC) of β-emitters (e.g. 3H, 14C, 32P , 35S). The ROTISZINT® scintillation cocktails are applicable for scintillation of aqueous samples in the entire biological, biochemical and chemical field.
Wide excitation range between 190 and 370 nm
emission maximum: 420-430 nm
The modern ROTISZINT® cocktails contain the same reagents as primary and secondary scintillators that were used in ROTISZINT®Eco plus. Thus, neither the excitation nor the detection wavelength change for the application.
We still recommend to use the same scintillation protocol in the first approaches with one of the new ROTISZINT® cocktails that was previously used with cocktail 0016. In many cases, the parameters are directly transferable. If the scintillation results are not satisfactory at first, the sample quantity (the ratio sample / cocktail) can be rebalanced.
ROTISZINT® Cocktails are supplied in black plastic bottles that can be used as stand-up containers. They allow safe and space-saving storage and use.
With a practical dispenser, you can conveniently and safely take out the amount of cocktail you need at any time. We recommend the use of ROTILABO®Dispensers (Art. No. HAC6.1-HAC9.1, HAE0.1 oder HAE1.1) and telescopic suction pipe (Art. No. AA92.1).
To withdraw the entire liquid, you can easily replace the inner withdrawal tube with a longer Teflon® or polyethylene tube (6 mm innerØ), or use the telescopic suction tube (order no. AA92.1).
