Info sui prodotti "Go Direct™ Colorimeter"

The 4-wavelength Go Direct Colorimeter measures absorbance or transmittance of a liquid sample. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.

Use this sensor to explore absorbance and percent transmittance in a variety of experiments including Beer’s law (absorbance vs. concentration) and kinetic studies (concentration vs. time). Students select between four wavelengths (430 nm, 470 nm, 565 nm, 635 nm) to set up their experiment.

Go Direct Colorimeter features one-step calibration for all four wavelengths. It’s as simple as inserting a cuvette of distilled water and pressing the Calibrate button.

Go Direct Colorimeter can be used in a variety of experiments:

Conduct Beer’s law investigations.
Determine the concentration of unknown solutions.
Study changes in concentration vs. time.
Monitor reaction rates.

Forensic Chemistry Experiments

Each of the 15 experiments in this book kicks off with a case study designed to engage high-school and college-level chemistry students. Immerse them in the excitement of solving crimes through hands-on experimentation using Vernier sensors such as pH, pressure, conductivity, and temperature to investigate complex questions involving forensics. Students explore gas pressure through a failed bottle rocket launch, Beer’s law through a case of poisoned wine, and even more through engaging forensics investigations. Electronic Version 14 ready-to-use student experiments Electronic access to up-to-date versions of the experiments Instructions for data collection with Vernier Graphical Analysis app with Go Direct sensors. (Does not support data collection with Logger Pro or LabQuest App) Essential instructor information, including teaching tips, suggested answers, and sample data and graphs Word-processing files of the student experiments, so you can edit the files to match your teaching preferences Complete equipment and supplies list A generous site license—buy one book and duplicate the experiments for your class Printed Lab Book When you buy the printed lab book you receive all of the resources listed for the electronic version, plus a printed copy of the book.

Go Direct™ SpectroVis® Plus Spectrophotometer

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). Spettroscopia con Go Direct SpectroVis Plus Per utilizzare lo spettrofotometro Go Direct SpectroVis Plus, scarica l'app gratuita Spectral Analysis. L'app è compatibile con computer, Chromebook e dispositivi mobili. Gli studenti possono anche collegarsi a LabQuest 2 o a un computer con Logger Pro per effettuare analisi. Specifiche Intervallo di lunghezze d'onda: 380 nm–950 nm Supporto per fluorescenza: due sorgenti di eccitazione centrate a 405 nm e 500 nm Intervallo di lunghezza d'onda riportato: ~1 nm tra i valori riportati (raccoglie 570 valori) Dimensioni: 16 cm x 10 cm x 5 cm Sorgenti luminose: Lampadina bianca a incandescenza, durata di circa 8.000 ore, calibrazione in un solo passaggio. Basato su LED, durata di circa 100.000 ore. Nessuna alimentazione esterna è richiesta.
