benefits of micropro
Benefits of MicroPRO
  • Détection simultanée des bactéries, levures et moisissures en 24 heures dans plus de 95% des produits testés à ce jour et pratiquement 100% en 48 heures
  • Détection simultanée des bactéries, levures et moisissures en 5 minutes dans l’eau purifiée et l’environnement
    • Cela vous permet de prendre des actions correctives immédiatement afin de ne pas contaminer tout un lot.
  • Limite de quantification égale à 20 ufc/mL
    • Soit 5 fois mieux que notre concurrent le plus proche grâce à l’utilisation d’un laser émettant dans le rouge (moins de bruit généré par les produits et l’eau à cette longueur d’onde) et à une meilleure conception de notre cellule
  • Plus grande stabilité, plus longue durée de vie de notre laser qui est en fait une diode laser émettant dans le rouge par rapport à un laser émettant dans le bleu.
  • Cellule en quartz dont la conception évite les bouchages et contamination internes
benefits of micropro1
Benefits of MicroPRO
  • La technologie de nos réactifs permet de marquer 100% des organismes morts et vivants ou vivants seulement ou mort seulement
    • La technique de marquage consiste à fixer une sonde fluorescente sur les acides nucléiques des micro-organismes. Il ne s’agit pas d’une réaction enzymatique qui est souvent incomplète ou qui ne génère pas suffisamment de fluorescence pour être détectée. Nous pouvons aussi concevoir des kits pour marquer des micro-organismes spécifiques sur demande.
  • Les réactifs peuvent se conserver pendant 10 jours à température ambiante dans les réservoirs de l’instrument
    • Par rapport aux technologies concurrentes, vous évite beaucoup de perte et donc limite les coûts. Cette technologie permet d’utiliser le système même pour un seul échantillon alors que dans la plupart des autres techniques il est préférable d’attendre d’avoir suffisamment d’échantillons à analyser avant d’ouvrir un kit qui ne se conservera que quelques heures après l’ouverture.
benefits of micropro2
Benefits of MicroPRO
  • Très grande reproductibilité
    • Le MicroPRO ajoute les réactifs lui-même contrairement à d’autres techniques qui nécessitent de les ajouter manuellement avant introduction dans l’automate. Les temps d’incubation sont donc les mêmes pour des échantillons identiques ce qui garantie une très grande reproductibilité des résultats.
  • La quantité de réactifs nécessaire à l'analyse de quantités inférieures à 100 ou 200 échantillons par semaine peut être dosée, ce qui permet de remettre le reste au frais pour un usage ultérieur plusieurs semaines ou mois après l'ouverture de l'emballage
    • Ceci est également une source d'économie considérable par rapport à d'autres techniques.
benefits of micropro3
Benefits of MicroPRO
  • La capacité du MicroPRO est de 42 échantillons sur 3 racks de 12 échantillons et 1 rack prioritaire de 6 échantillons. Lorsque le MicroPRO a terminé l’analyse d’un rack il est possible de le sortir et de le recharger sans interrompre la séquence d’analyse
    • Par conséquent le système peut fonctionner en continu toute la journée.
    • Si des échantillons sont positionnés sur le rack prioritaire, le système les détectera et interrompra la séquence d’analyse sur un des racks standard après l’analyse des échantillons en cours. Il analysera les échantillons du rack prioritaire et reviendra à l’endroit où il s’était arrêté sur le rack standard pour poursuivre la séquence.
    • Ceci vous permet d’analyser des échantillons en urgence sans devoir arrêter manuellement la séquence d’analyse.
    • Les racks n’ont pas besoin d’être totalement remplis pour démarrer une analyse. A partir du moment où un seul échantillon se trouve sur un rack, l’analyse peut démarrer.
benefits of micropro4
Benefits of MicroPRO
  • Pas de risque de contamination croisée
    • Les racks sont conçus pour recevoir 12 échantillons ou 6 échantillons pour le rack prioritaire ainsi que 12 ou 6 seringues à usage unique d’un millilitre
    • Ces seringues sont utilisées par l’automate pour injecter chaque échantillon une seule fois dans le cytomètre.
    • Cela permet d’éliminer un risque de contamination important lorsque la même seringue est utilisée pour injecter tous les échantillons.
    • Par ailleurs le port d’injection du cytomètre est lavé systématiquement et automatiquement entre deux injections avec une solution de détergent qui a été qualifiée par le fabriquant. Cette fonction n’est pas débrayable par l’utilisateur ni les managers qui entrent les méthodes dans le système. Cela garantit une absence totale de risque de contamination croisée.
    • Notre système à fait l’objet de tests très approfondis à la fois en interne et par nos clients pour nous assurer que le risque de contamination est totalement absent.
benefits of micropro5
Benefits of MicroPRO
  • Le système permet d’analyser jusqu’à 20 échantillons par heure.
  • Le logiciel très convivial répond à la norme 21 CFR Part 11 exigée par l’industrie pharmaceutique. Ce logiciel permet de visualiser les résultats en ufc/ml ou en pass/ambiguous/fail à condition d'avoir préalablement indiqué les limites pour accepter un lot, le refuser ou dans certain cas de préciser si la mesure est ambiguë et ainsi relancer des analyses complémentaires. Ce logiciel comprend plusieurs niveaux.
    • Le premier est le niveau utilisateur qui ne permet pas de modifier ou d’entrer des nouvelles méthodes.
    • Le deuxième niveau est le niveau manager qui permet d’entrer ou modifier des méthodes.
    • Le troisième niveau est le niveau administrateur
    • Le quatrième niveau service permet à nos équipes de maintenance d’intervenir sur le système en coupant toutes les sécurités.
