Our single-use Filtration System

Our single-use filtration system now offers a new feature: An optional choice to integrate supplier-independent filters has been added to the RoSS.Fill platform in order to further enhance the speed and reliability of bulk drug substance production. In an environment as sterile, complex and fast-paced as the pharmaceutical industry, the advantages of single-use filters are clear:

Easy handling combined with the omission of tedious cleaning and maintenance work should be enough to convince any player in the industry; add to that inexpensive hardware costs and it makes absolute sense to add filters as a new component in the range of sterile compound and segregation options to the fully automated platform. Whether you are looking to reduce bioburden during cell harvesting or want to influence viral vectors in terms of their effect, the RoSS.FILL system now also offers you a filtration option, thus covering the entire biopharmaceutical logistics process. With sufficient filter surface area and a choice of pore sizes for different substances and volumes, the integrable filters are yet another key feature of our single-use filtration system.

FAQ about single-use aseptic filling system

What is an aseptic filler?

Aseptic fillers are aseptic filling machines that are used in the pharma industry in order to maintain a sterile environment in the process of fluid management. They are made to prevent the processed drug products from being contaminated with germs while they fill them into sterilized containers before sealing these. 

With the aim to facilitate a secure, flexible and reliable filling process, Single Use Support has developed the RoSS.FILL platform, with single use filling machines both for lab and bulk scale production.

What is an aseptic bag?

An aseptic bag is a germ-free container that is used within the supply chain of several drug products. Sufficiently sealed, aseptic bags like Single Use Support’s IRIS Single-use bioprocess containers are designed to prevent the products that are stored within them from being contaminated.

Aseptic bags need to be sterilized before they can be used; the four main ways to do so are:

  • sterilization by heat
  • sterilization by radiation
  • mechanical sterilization
  • chemical sterilization

What are the requirements in the aseptic area?

The aseptic area requires maintaining a sterile environment for drug materials all the way from the manufacturing site to the place of application. This implies the necessity of specialized equipment that accompany this complex process as soon as the drug product is sterilized, including aseptic filling machines and tubing, sterile containers and a sterile filling environment. 

Additionally, the containers have to be sufficiently sealed in order not prevent contamination along the supply chain of the drug product.

What is the difference between aseptic and septic?

While describing something as septic implies that it is contaminated with germs and potentially harmful or – in the case of tissue – damaged, aseptic means the opposite, as a consequence of adding the prefix a. Aseptic is normally used to describe a process that is kept germ-free, and has a similar meaning as the word sterile; the latter, though, is most commonly used to describe a specific environment that is free of germs.

What is the difference between antiseptic and aseptic?

In the field of germ-free processes, there are various terms that seem similar but have a slightly different meaning to them. This also applies to the words aseptic and antiseptic; while antiseptic is used when talking about making an environment free of germs, aseptic refers to keeping it this way.

What is an aseptic filling machine?

An aseptic filling machine is part of the supply chain of various goods, including several drug products. It is designed to facilitate the filling of drug products into pre-sterilized containers, before these are sealed.

Considering the need for highest accuracy within this process, aseptic filling machines need to be extremely reliable; Single Use Support has therefore developed the RoSS.FILL platform with high quality aseptic filling machines for different fields of application.

How is aseptic packaging done?

Aseptic packaging is performed when a sterile product is transferred into an equally sterile container, before the latter is hermetically sealed. This happens in a sterile environment, as it is vital to prevent the processed drug product from being contaminated with germs.

The steps included in aseptic packaging are:

  • sterilization of the processed products
  • sterilization of the containers that the products are to be brought into
  • ensuring the included devices and other tools are sterile
  • maintaining a sterile environment before hermetically sealing the containers.

Is aseptic and sterile the same?

Both the terms aseptic and sterile refer to a germ-free state. However, the context the two words are used in are different:

  • aseptic: frequently used to describe processes that are performed under exclusion of germs in order to prevent involved individuals and components from contamination.
  • sterile: often used to refer to an environment that is kept or made germ-free; for instance, it can occur whilst describing ORs or surgical instruments.

What is aseptic filling in the pharma industry?

Aseptic filling in the (bio)pharma industry describes a process performed to prevent a drug product from contamination on its way from the manufacturer to its application. By the means of specialized filling systems, the products are filled in sterile containers without being exposed to germs like bacteria. Since the entire filling process is kept aseptic, final sterilization is not necessary.

What is sterile filling?

Sterile filling is a process carried out in a sterile environment, where a sterile drug product is transferred into equally sterile containers. The process is performed when contamination of drug products with germs is to be avoided, and involves dedicated filling solutions.

What is single use bag filtration?

Single use bag filtration is usually performed during the process of single use bag filling and is vital to guarantee product quality. It is carried out to remove impurities from the processed drug substances when they are filled into single use bags.

How does the liquid sampling system by Single Use Support work?

Single Use Support’s filling and draining system functions as a highly professional liquid sampling system for drug products – be it on lab scale or on bulk scale. It can either fill liquids in bags, bottles or vials at a high accuracy, with controlled pressure. Furthermore, an integrated sensor allows airless filling, optionally including the integrated filtration of your product.

The single-use bioprocess containers are well protected by the RoSS.SHELL system, allowing for plate freezing to be performed right after the filling process.

The liquid path of the biologics is fully disposable – from the sterile connectors to tubing –, which saves costs and resources.
