Adjustable transfer rate during reconstitution

Tailor-made transfer systems

Successful reconstitution of lyophilized medications depends crucially on the properties of the active substance as well as the solvent. That's why transfer systems are available with parameters that can be individually adapted. The nextaro® premium transfer system can be tailored to your specific requirements.

Special requirements

Protein-based medications (such as coagulation factors) can be stored more safely and last longer with freeze-drying (lyophilization). Modern transfer systems make reactivation of lyophilized substances easy and reliable for the user. Transfer systems need to be easily adaptable to the specific requirements of the application because the physical properties of the active substances and the solvents can differ.

Individual requirements

The solubility of the active substance as well as the volume and viscosity of the solvent are decisive for successful reconstitution of lyophilized medications. The angle and force with which the jet of liquid hits the lyophilized cake are particularly important. If the jet is too strong, foam may form and cause denaturation or clumping of the active substance. Ideally, the jet of solvent is directed gently down the walls of the vial in order to dissolve the active substance slowly from below. Adjustment of the transfer rate is therefore essential for complete reconstitution and standardized concentration of the active substance in the prepared solvent.

Innovative solutions

To maintain a regulated transfer speed of the solution when reconstituting a lyophilized medication, the nextaro® premium transfer system contains an integrated throttle, which can be implemented to match your individual requirements. This ensures that, through customizing and specifying the internal geometry and thus the flow characteristics, the liquid jet will be adapted specifically to the solvent volume and the solubility of the active substance. This gentle form of reconstitution prevents foaming, clumping and denaturation.
