Lyophilization Services
MBU-Technology LLC offers freeze-drying of your products.
The team of experienced company's employees will provide the assistance in setting of optimal lyophilization parameters for all products and give advice on the arising questions:
- to find the eutectic point of your product;
- to set the right temperature and the time of lyophilization;
- to choose the right additives for the freeze-dried mixture to improve product stability.
The method of lyophilization is based on sublimation of frozen products under extremely low pressure. Lyophilization process involves product freezing, primary drying in vacuum at negative temperature, secondary drying at positive temperature and sealing of bottles, if the last step is required.
Lyophilization is applied in case of long-time storage and conservation of biogenic products such as:
- standard panels of human blood serum;
- microbiologic specimens;
- virologic specimens;
- medical preparations and vaccines;
- ferments for R&D, human and veterinary use;
- ready-to-use reaction mixtures for PCR.
The most distinct advantages of lyophilization:
– long-time storage of the final product;
- freeze-dried products remain structurally integral and biologically active (being damped, the product tends to restore its initial properties);
- freeze-dried products are freely soluble;
- absence of foaming;
- low-weight final products.
Optional services (for the solutions dried in bottles):
- solution preparation;
- bottling of solutions;
- closing of bottles with dried solutions;
- marking / labeling.
Our advantages:
An appropriate choice of drying parameters depending on product and customer requirements, exclusion of minimum orders, contract price, payment only for the lyophilizer operating hours.
