Description

Key features

• Amélioration du débit : mesurez plusieurs échantillons et quantifiez l’ADN, l’ARN et les protéines jusqu’à 50 % plus rapidement que les lecteurs à échantillon unique
• Flexibilité : mesurez jusqu’à huit échantillons simultanément
• Système complet optimisé—fonctionne de manière transparente avec les réactifs Qubit pour générer des résultats fiables, sensibles et spécifiques
• Quantification précise : niveaux de précision élevés avec seulement 1 à 20 μL d’échantillon, même avec des échantillons très dilués
• Calculatrices embarquées—génère rapidement les instructions de préparation de la solution de travail Qubit et détermine la molarité de vos échantillons
• Facile à utiliser : un grand écran tactile couleur de 8 pouces à la pointe de la technologie et une interface utilisateur intuitive facilitent la navigation dans le flux de travail
• Flexibilité d’exportation des données : les données sont facilement transférées à l’aide du dongle Wi-Fi inclus, d’une clé USB ou directement sur votre ordinateur
