We are manufacturers of freeze driers in India since more than two decades. Our equipments 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. Our freeze drier removes moisture from all the biological samples while ensuring that the structural integrity along with the biological and chemical activities are preserved.
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.
Our freeze drier have a variety of usage in R & D laboratories, research studies and product testing facilities across the globe.
Apart from that, these freeze drier have a variety of usages in tissue culture applications, enzyme reaction studies, growth observation studies, fermentation analysis and various other general and specialized applications in various laboratories.
We specialize in both standard and customized models, specifically designed to meet the challenging demands of various scientists for individual and specialized research applications. Over a short period of time Weiber brand have been established as reliable exporters of freeze drier in India, catering to the vast markets in South East Asia, Middle East, Africa and Europe.
Apart from that we are supplying our freeze drier in India, catering to a variety of customers ranging from Defence Installations, Research Laboratories, Educational Institutes and various R& D laboratories of leading national and multinational companies.

Construction Details:
Weiber freeze drier are double walled cooled units. Outer body of our freeze drier are constructed out of thick PCRC sheet duly pre-treated with primers and rust proofing and painted with long lasting stove enamel or elegantly powder coated.. The inner chamber is made of heavy gauge stainless steel sheet of SS-304 grade. The gap between the walls is filled high grade mineral glass wool, which ensures maximum thermal efficiency .
The unit is provided with a non magnetic ss bottom for an easy removal of effluents. The vacuum drum of our unit is made of stainless steel sheet of ss-304 grade with top cap made of heavy Perspex sheet of 8/12” valve for manifold drying. Our lypholizer is provided with high efficiency double stage vacuum pump to speedify the drying process . The moisture content of the sample is reduced to approx 5%.
Cooling:
An energy efficient cooling unit is installed in our freeze driers. We use ISI marked high end CFC free compressors of Kirloskar/Tecumseh make, conforming to latest international standards and guidelines.
Temperature Control
The temperature inside our freeze drier is controlled through programmable micro-processor based temperature controller cum indicator. Both the chambers have their individual control modules.
Temperature Range.
Temperature range of our standard freeze drier models are upto -30o c However we have the capacity to modify the same to suit the individual specialized requirements of our customers.
Temperature Sensitivity:
Temperature inside our freeze drier are controlled with a sensitivity of + 1o c or better.
Front Panel:
Front panel of our units comprises of on/off switches , cooling and mains indicator lamps, temperature controllers and voltmeters.
