Freeze Drying is the process of removing the moisture from a biological product while maintaining the Integrity of the products biological & chemical structure and activities. Freeze drying technology is used in particular for removal of moisture from the products usually of biological origin without causing any noticeable change in the original characteristics. Freeze Drying is also the preferred process in the field of Pharmacy, Chemistry and in conservation of food. Heat-sensitive biological materials may be freeze-dried without affecting their potency. The dried materials may be stored for years at room temperature without loss of their original characteristics. The freeze-dried material may be transported and shipped in small containers, and no provision is necessary for refrigeration en route.
Beside the normal drying applications our freeze driers are fit to be used for various applications tests involving micro-organisms, plants, tissues etc apart from various customized industrial and research applications.
Bacterial growth and enzyme action do not take place in freeze-dried products. Proteins do not coagulate. Oxidation of many materials such as hemoglobin’s and vaccines is completely prevented when drying and sealing is done under high vacuum.
Features:
Freeze Dryer Covers a range of application from multi-user centralized laboratory application, pilot plant determination works etc. This unit is mounted on castors. The unit has hermetically sealed one compressor maintains temperature up to minus 70°C. Trap is given at non magnetic stainless steel dished bottom for complete effluent removal. Refrigerant Coils made of Copper are heavily insulated for maximum efficiency in the condensing chamber. Temperature controller cum indicator Vacuum drum is made of non magnetic Stainless steel with Perspex top cover and incorporates 8/12" Quick seal valves/ports for manifold drying. Double stage Vacuum pumps with gas ballast giving vacuum 1 X 10-3 torr module gauge sample port having 12.5mm outer dia provided for Quick drying however, moisture contains would be around 5% in the specimen.
Electronic Vacuum indicator Pirani gauge is used. Specially designed temperature indicator to read temperature as low as 70°C, mounted on front panel. Suitable work on 220V single phase. 50HZ A.C.

Freeze Drier is the process of removing the moisture from a biological product while maintaining the Integrity of the products biological & chemical structure and activities. WEIBER Laboratory Freeze Drier are conceptualized and designed to provide moisture removing solutions to all the microbiology, biochemistry, biotechnology and genetic engineering laboratories which require complete moisture removal and storage facilities of various biological agents/material. Beside the normal drying applications our freeze driers are fit to be used for various applications tests involving micro-organisms, plants, tissues etc. Bacterial growth and enzyme action do not take place in freeze-dried products.

The freeze-dried material may be transported and shipped in small containers, and no provision is necessary for refrigeration route. The products also knowns as Laboratory Lyophilizer.
Special Features:
Micro-processor based Controllers(HMI+PLC as an option)
Hermetically sealed compressor maintains temperature up to -80°C
Temperature controller cum indicator Vacuum drum is made of non magnetic Stainless steel
Quick seal valves/ports for manifold drying.
Vacuum Pump - Providing an environment that allows for easy removal of water molecules from the sample is critical to successful freeze drying. A vacuum pump is needed to lower the pressure around the product being freezed. Select from standard or chemical resistant models to enable freeze drying with more aggressive solvents
Sample containers - Sturdy, borosilicate glass vessels options include flasks, serum bottles, vials, and ampules
Range of manifolds in clear acrylic or stainless steel for superior corrosion resistance
One-button auto start-up and shut-down activates all operating parameters in a correct and safe sequence, protecting the product and equipment
Hot gas defrost and smooth-walled condensers for fast turnaround and minimal delay between runs
CFC free cooling
Ethernet communication and USB ports

Pilot Scale Freeze Dryer are specially designed for drying processes of large-scale production units(20-100 litres). Prefreezing and drying will be realized on liquid temperature controlled shelves inside the separate drying chamber (double-chamber-system). Due to the temperature control of the stainless steel shelves (via a synthetic heat-transfer medium), these pilot systems fulfil the highest standards of the pharmaceutical and biotech industries.

Special Features:
Defrosting without water: Radiation from shelf defrost ice condenser coils fast and efficient. No production of additional waste.
Most efficient condenser design : Ice condenser coils directly inside drying chamber improves drying time and prevents vapour bypass to vacuum pumps.
Vial stoppering plus flask drying: Multi-purpose device with optional connections for up to 4 flasks. Controlled and safe vial stoppering via manual operation (automatic as option).
