Use Scenarios

Pharmaceutical Bioprocess Development Environment

In pharmaceutical bioprocess laboratories, the cell culture flask is fundamental for upstream research and development tasks, such as optimizing cell growth conditions for biologics manufacturing. Within this environment, it functions as a sterile containment vessel facilitating cell expansion before transfer to larger bioreactors. The flask’s structural integrity and compatibility with automated handling systems improve process consistency and reduce contamination risk. Use of the cell culture erlenmeyer flask variant supports suspension culture protocols by enabling controlled agitation, improving oxygenation, and facilitating scale-up trials. Integration with quality control workflows ensures compliance with regulatory standards from early-stage development to production.

Cell-Based Diagnostic and Research Laboratories

In diagnostic and research institutions, the cell culture flask supports assays requiring precise cell proliferation under sterile, replicable conditions. It serves as a primary culture vessel for generating cell populations for cytotoxicity testing, gene expression studies, and phenotypic screening. The cell culture erlenmeyer flask enhances these workflows by providing uniform mixing and gas exchange, critical for suspension cultures used in immunological and molecular biology applications. Its design allows smooth incorporation into biosafety cabinet workflows and downstream processing units. This compliance with contamination control and process traceability standards enables reliable data generation aligned with laboratory accreditation requirements.

Commercial Procurement FAQ

·Can screw cap micro tubes be used at temperatures below zero centigrade?

Based on our general experience, the screw cap micro tubes can be used to freeze aqueous solutions at temperatures of up to -86°C, except in the case of demineralised water (purified water) solutions. With demineralised water, there are generally critical freezing situations which can lead to the formation of cracks. Here, successful freezing of the tubes is always dependent on many factors. These include the medium to be frozen, the rack used and the mechanical load on the tubes. The use of tubes at temperatures below zero centigrade should therefore be tested under the routine conditions of the user. 

For cryopreservation, we recommend using Cryogenic  tubes.

·Is there a recommended torque for micro tube screw caps?

The torque for caps for machine tightening should be between 15 and 18 Ncm.

·Can screw cap micro tubes be stored on dry ice?

The shipping of samples on dry ice is a common method, but we are aware of some problems associated with this type of shipping. When shipping in this manner, it is necessary to ensure that the tubes are packed so that they are protected as well as possible and appropriately fastened to avoid damage.

·Can screw cap micro tubes and reaction tubes be autoclaved?

Screw cap micro tubes and reaction tubes can be autoclaved at 121°C without any appreciable loss of mechanical properties. When doing this it is important not to screw on/push down the cap to seal it. The user must check whether other product characteristics are affected by autoclaving in terms of the desired use.
