The Spider™ Sample Extractor

The Spider

Sample Extractor for Freeze Dryers

The Spider is a new generation sample extractor that simplifies the vial extraction process while increasing reliability and performance. Our simple, elegant design features minimal sealing surfaces to help eliminate leaks. The Spider offers the smallest profile of any sample extractor on the market today. When mounted on a full view acrylic door, it provides maximum visibility throughout the product chamber.

The Spider sample extractor includes two removable grippers for vials sized from 2ml to 50 ml and a removable extraction rod that can be stored when not in use, providing additional room as well as safety. Without the extraction rod, the remainder of the extractor extends only 20” from the door. The design of this sample extractor does not require an additional vacuum pump.
