Alumen 450™ in Pre-Loaded Cuvettes

Alumen 450™ is a unique turn-on fluorescence probe, that is highly selective for Aluminum over other dissolved cations, that can both detect and quantitate dissolved Aluminum Al3+.

Sales price: $799.00


Alumen 450™ is a turn-on fluorescent sensor, meaning that the solution fluorescence increases as a function of the concentration of dissolved Aluminum. Alumen 450™ can readily be excited over a broad wavelength range from 280-400 nm with an extinction coefficient of 8300 ± 600 M-1 cm-1 at 318 nm. The fluorescence emission is very strong in the presence of Aluminum ions, centered at ≈ 420 nm.

Alumen 450™ ready chelates dissolved Al3+ and subsequently shows an increase in the emission spectra for Alumen Blue™ in the presence of dissolved Al3+, i.e. it gets significantly brighter.  The probe increases its fluorescence emission > 300% in going from 0 → 750 µM Al3+.  Alumen 450™ shows an almost linear response to Al3+ from 1 → 300 µM dissolved Al3+. Alumen 450™ is also a highly selective probe for both the detection and determination of dissolved Al3+ over other dissolved cations.

In this kit, Alumen 450™ is already conveniently preloaded into a box of 100 plastic cuvettes (transmission down to 285 nm). These cuvettes allow for dissolved Aluminum detection in a Fluorescence based format. With these convenient pre-loaded cuvettes, there is no reconstitution procedure necessary, simply add 3 ml (3cm3) of your sample to each cuvette and measure, it’s that simple.

For optimum performance, probe vials should be stored at -2 to -8 °C when not being used and < - 20 °C long term. Probe solutions should be used after dilution.
