Transforming Molecules into Cutting-Edge Films:

LePure Biotech’s Innovations in Biopharmaceutical Consumables

In recent years, the biopharmaceutical industry has witnessed a remarkable surge in the demand for single-use consumables. However, this surge has been met with significant challenges due to inadequate production capacity and an unstable supply chain, resulting in a critical global shortage of disposable consumables.
In response to this complex technical conundrum, we are proud to introduce the LeKrius Bioprocess film, a comprehensive solution that tackles the issue at its core, spanning from raw material formulation to coextrusion processes. Every aspect of the LeKrius Bioprocess film is designed and manufactured by LePure Biotech, effectively alleviating the shortage of single-use consumables.

Case Study 

  • Experiment Objective:

Test the impact of different membrane materials on the growth density and cell viability of CHO K1.

  • Experimental Parameters:

Cell Types: CHO K1

Culture Medium Extraction Conditions: 37°C, 3 days

Area-to-Volume Ratio: 3 cm²/mL

  • Experimental Membrane Models:

LeKrius Membrane VS Competitor, negative bottles control

  • Conclusion of CHO K1 Cultivation Experiment:

Live cell density is generally comparable to bottle cultivation, superior to the Competitor.

Over the 14-day cell culture period, cell viability remains close.

The use of single-use systems involves a variety of raw materials, such as biopharmaceutical films, various connectors, and multiple types of tubing, among others.
