Informations sur le produit "Go Direct® Mini GC™"

Go Direct® Mini GC™ – Chromatographe en phase gazeuse

Le Vernier Go Direct® Mini GC™ de nouvelle génération permet d’identifier un plus grand nombre de composés que son prédécesseur. Cela est rendu possible grâce à une température maximale de fonctionnement de 160 °C et à un capteur à sensibilité commutable.

L’appareil utilise par défaut l’air ambiant comme gaz vecteur, ce qui facilite son utilisation et renforce la sécurité. D’autres gaz vecteurs peuvent toutefois également être utilisés.
L’analyse et l’intégration des pics peuvent être réalisées soit via l’application Instrumental Analysis (iOS / Android / Chromebook) en mode autonome, soit avec le logiciel Logger Pro sur ordinateur.

Détecteur – MCCD

La technologie avancée MEMS GC-Chip permet l’utilisation de l’air ambiant comme gaz vecteur tout en offrant la possibilité d’utiliser d’autres gaz.

Go Direct® Polarimeter

Its unique vertical layout and lack of custom glassware make this polarimeter very student friendly. In addition, the analyzer is automatically rotated by an internal motor giving students more time to understand experiments such as the reaction kinetics of HCl and sucrose. The 589 nm LED makes it ideal for comparing optical rotation values to those in literature, allowing students to calculate specific rotation for sucrose, fructose, and other optically active samples. Students no longer have to determine the optical maximum with their eye—they now have a graph that shows a clear change in the light’s polarization. Specifications Light source: LED Wavelength (nominal): 589 nm Accuracy (optical rotation measurements): ±1° Rechargeable Battery—Ready When You AreThe robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Go Direct™ Melt Station

The Go Direct Melt Station accurately determines the melting temperature of solid substances. It directly connects wirelessly via Bluetooth® or wired via USB to your platform. Teach students the visual detection capillary method of melting point determination with the Go Direct Melt Station. It accurately measures melting temperatures of a solid (up to 260°C), and the real-time graphing provides a unique perspective of the melting process. The wide-angle observation and magnification window, LED-lit heater block, and adjustable tilt base give students a clear view of the substance as they witness the state change. Internal cooling fans reduce the waiting time between sample testing. Also included is an important safety feature that automatically powers down the heating block after 60 minutes with no change to the control knob. The Go Direct Melt Station can be used in a variety of experiments: Determine the melting temperature of an known organic solid such as aspirin, ibuprofen, or caffeine. Identify an unknown organic solid by its melting temperature. Use melting temperature to analyze reaction products.
