Lo spettrofotometro Go Direct SpectroVis Plus misura rapidamente l'intera lunghezza d'onda. Si collega direttamente alla piattaforma in modalità wireless tramite Bluetooth® o cablato via USB. Introducete i vostri studenti alla spettroscopia con l'economico spettrofotometro Go Direct SpectroVis Plus. In grado di collegarsi wireless o via USB, questo dispositivo può facilmente raccogliere l'intera lunghezza d'onda (assorbanza, trasmissione percentuale o intensità) in meno di un secondo. Una volta determinata la lunghezza d'onda di picco, è possibile stabilire la concentrazione di una soluzione (legge di Beer) o monitorare la velocità di reazione. Un percorso luminoso ridotto consente allo spettrofotometro Go Direct SpectroVis Plus di essere utilizzato per microlaboratori e applicazioni biochimiche con micro e semi-micro cuvette. Lo spettrofotometro Go Direct SpectroVis Plus può essere utilizzato in diversi esperimenti di spettroscopia: Determinare la lunghezza d'onda del picco per raccogliere dati sulla concentrazione della soluzione per studi sulla legge di Beer o per monitorare le velocità di reazione. Raccogliere uno spettro a lunghezza d'onda completa per misurare l'assorbanza, la trasmittanza percentuale, la fluorescenza (a 405 nm o 500 nm di eccitazione) o le emissioni. Condurre esperimenti di cinetica enzimatica. Effettuare studi sull'equilibrio di assorbanza vs tempo o assorbanza vs concentrazione. Effettuare biotest colorimetrici o fluorescenti. Utilizzate lo spettrofotometro a fibra ottica (VSP-FIBER) per misurare le emissioni provenienti da prove alla fiamma o da altre sorgenti luminose. Per un'analisi più dettagliata delle emissioni, prendete in considerazione lo spettrometro Vernier Emissions (VSP-EM).
