General purpose freeze dryer for bulk samples

Preserve delicate artifacts and specimens effectively with a versatile freeze drying solution, ideal for conserving historical documents or preparing genetic research samples, even when working with large or low-moisture items.

Preserves and Dehydrates Artifacts and Specimens

The VirTis General Purpose Freeze Dryer (GPFD) from Scientific Products offers a versatile solution for effective preservation and dehydration tasks in archaeology and museum conservation. With the ability to handle bulky items, it’s ideal for applications requiring low energy input and long freeze-drying cycles, such as archaeological artifact restoration and genetic plant analysis. Available in 25L and 35L configurations, the GPFD employs adjustable condenser refrigeration down to -85°C, optimizing energy use and minimizing environmental impact. Its free-standing, mobile design facilitates easy integration into laboratory or processing operations. The clear acrylic chamber doors allow for progress monitoring, and its mid-cycle defrost option simplifies ice removal. This equipment is configurable with optional programmable heating and is designed to maintain the integrity of sensitive materials like ancient manuscripts and taxidermy specimens, ensuring their preservation for future generations.
