General description
Les dispositifs de filtration stérilisante Stericup® et Steritop® utilisent des membranes fiables et hautement performantes pour une filtration stérilisante optimale des réactifs, tampons et milieux de laboratoire. Ces dispositifs associent des débits et des volumes filtrés supérieurs à une faible liaison non spécifique et à une conception stable et évitant tout basculement.
Cette unité de filtration à membrane en polyéthersulfone (PES) Stericup® de 0,22 µm de dimension de pores associe une unité de filtration pour flacon de 1 000 ml avec un flacon de réception de 1 000 ml et un bouchon pour le traitement et le stockage.
Application
- Milieux de culture cellulaire ± additifs
- Tampons
- Solutions biologiques
Features and Benefits
- L'entonnoir du filtre Quick Release se déconnecte du flacon de réception en un quart de tour, ce qui réduit le risque de déversement et facilite la manipulation sur la paillasse ou sous la hotte.
- L'identification en gras du produit sur l'entonnoir Steritop® affiche clairement les caractéristiques de la membrane, notamment la composition et la taille des pores, pour une sélection rapide du produit adapté à l'application.
- Le bouchon à fermeture par clic est muni d'une collerette et est modifié pour assurer une prise en main sûre aussi bien en conditions humides que sèches et une butée tactile confirme que la fermeture est sécurisée. Ne vous inquiétez pas du risque de déversement ou de contamination du contenu stérilisé.
- Une large zone d'écriture dépolie sur le flacon de réception et la couleur plus claire du bouchon permettent un étiquetage clair pour améliorer la lisibilité et réduire les bavures.
- Le bouchon à fermeture par clic repose sur le côté pour éviter tout risque de contamination.
- Les flacons de réception sont empilables pour gagner de l'espace de stockage.

Can the bottle be autoclaved and reused after storage? I understand that the filter is temperature-sensitive, but what about the bottle itself?
1 answer-
For the S2GPU11RE and all Stericup/Steritop products, these are designed to be one time use only. We have not studied the effects of autoclaving or reusing this on the plastic.

What is the maximum processing volume for Stericup® and Steritop® filters? Can I add more volume after initial filtration?
1 answer-
All Stericup® and Steritop® filters were developed for single-use application. The maximum volume is dependent on the receiver bottle capacity. Stericup® filters come with a receiver bottle with a specified maximum volume. For Steritop® filters, the maximum recommended volume is 2 L with an appropriate-sized receiver bottle. Larger processing volumes can result in membrane fouling, increase chance of spillage and contamination, and lead to possible airlock*.
*Note that devices with PES membranes can airlock if filtered to dryness. Some liquid must be left on top of the filter, then the system stopped, receiver changed or emptied, and more sample volume added before restart. This increases the chance of spillage.Helpful?

Can we filter oil-type liquids with Stericup® filters?
Can we filter oil-type liquids with Stericup® filters?
1 answer-
Likely not, due to pore size/possible fouling/chemical compatibility. Refer to our guide, "Chemical compatibility of filter components": https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/302/855/membrane-chemical-compatibility-ds2532en-ms.pdf
