Expanded Surface Polystyrene Roller Bottle

An expanded surface roller bottle is a specialized laboratory container used for the culture of adherent cells. It is an enhanced version of a regular roller bottle, designed to provide a larger surface area for cell growth.

The expanded surface roller bottle consists of a cylindrical shape made of polystyrene, with a screw cap or vented cap for gas exchange. The interior surface of the bottle is treated with vacuum plasma surface treatment technology, enhance cell adhesion ability, can also be coated with collagen on the inner surface according to customer requirements.

The main advantage of an expanded surface roller bottle is its increased surface area compared to traditional roller bottles. This larger surface area allows for the culture of a higher number of cells, resulting in higher cell yields. It is particularly useful when working with cells that require large-scale production, such as vaccine production or biopharmaceutical manufacturing.

The ESR bottle is typically placed on a roller apparatus, which gently rotates the bottle to provide a dynamic culture environment. The rotation ensures that the cells receive uniform nutrients and oxygen distribution, preventing the formation of gradients and maintaining a healthy cell population.

Researchers and manufacturers often use expanded surface roller bottles in the production of various cell-based products, including monoclonal antibodies, recombinant proteins, and viral vaccines. They provide a cost-effective solution for large-scale cell culture, simplifying the process and increasing productivity.

It's important to note that while expanded surface roller bottles offer advantages for certain cell culture applications, there are alternative systems available as well. Depending on the specific requirements of the cells being cultured, other vessels such as cell factories, multi-layered cell culture vessels, or bioreactors may be more suitable.
