Ordering and configuration

Project-based

ePILOT BR is configured per project. To define the right MU/MB package, volumes and options (utilities, sensors, software and compliance), please contact TECNIC with your URS or request the configuration questionnaire.

The information provided above is for general reference only and may be modified, updated or discontinued at any time without prior notice. Values and specifications are indicative and may vary depending on project scope, configuration and applicable requirements. This content does not constitute a binding offer, warranty, or contractual commitment. Any final specifications, deliverables and acceptance criteria will be confirmed in the corresponding quotation, technical documentation and/or contract documents.

Cellular configuration

The cellular configuration of the eLab Advanced is equipped with a pitched-blade impeller designed to support efficient mixing for cell culture processes in both laboratory development and early scale-up. The blade geometry promotes mainly axial flow, helping to distribute gases, nutrients and pH control agents uniformly throughout the vessel while keeping shear stress at a moderate level. This makes it suitable for mammalian, insect and other shear-sensitive cell lines when operated with appropriate agitation and aeration settings. In combination with the vessel aspect ratio and baffle design, the pitched blade supports stable foaming behavior and reproducible oxygen transfer, which is essential when comparing batches or transferring processes between working volumes.

Operators can fine-tune agitation speed to balance oxygen demand and mixing time without excessively increasing mechanical stress on the culture.

Technical specifications

Models and working volumes

Tank

The ePlus Mixer platform combines an ePlus Mixer control tower with Tank frames and eBag 3D consumables. Tank can be supplied in square or cylindrical configurations (depending on project) to match the bag format.

Tank 100 L	100 L	20 L
Tank 200 L	200 L	30 L
Tank 500 L	500 L	55 L

*Values based on agitation start interlocks per tank model. Final performance depends on the selected eBag 3D, fluid properties and configuration.

Design conditions and operating limits

Reference

Reference limits are defined for the ePlus Mixer and the Tank. It is recommended to validate the specific limits of the selected eBag 3D and single-use sensors for the customer’s process.

Element	Operating pressure	Maximum pressure (safety)	Maximum working temperature
ePlus Mixer (control tower)	ATM	0.5 bar(g)	90 °C
Tank	ATM	0.5 bar(g)	45 °C
Jacket (if applicable)	N/A	1.5 bar	Depends on utilities / scope

The 0.5 bar(g) limit is associated with the equipment design, the circuit is protected by a safety valve. Confirm final limits on the equipment nameplate and project specification.
