PRODUCTS | TrayCell

TrayCellLa TrayCell di Hellma e' una cella di campionamento ultra micro. E' disegnata per misure di DNA/RNA e proteine.
  
La TRAYCELL è compatibile con spettrofotometri UV-VISIBILE di ogni marca e modello.
   
Grazie ad un’ottica interna a fibre ottiche, la finestra di lettura e’ situata sulla superficie di testa della cella: 4-5 µl di campione posizionati con micropipetta sono sufficienti all’analisi.
  
Il campione e’ poi rimosso dalla superficie con un semplice panno a secco o con tradizionali solventi. 

Dopo il posizionamento iniziale, la cella non viene mai rimossa dal portacelle dello spettrofotometro durante tutte le fasi di caricamento/pulizia della serie di campioni in analisi.
