Automated Tissue Processor NATP-100 is a benchtop linear closed tissue processor, a compact instrument designed with latest technology for complete automatic dehydration and infiltration of biological samples, up to final paraffin bath. All the reagents and paraffin containers are closed to prevent evaporation. Ion filter prevent solvent, odors and pollution. It can be programmed for immediate or delayed start; immersion time can be set from 1 min to 99 hours and 59 minutes.NATP-100 is a benchtop linear closed tissue processor, a compact instrument designed with latest technology for complete automatic dehydration and infiltration of biological samples, up to final paraffin bath.
