Rabbit limb-bone preparation for nucleic-acid extraction
The experiment paired JXFSTPRP-CLN with a 50 mL steel jar and a 10 mm stainless-steel ball. The jar was pre-cooled in liquid nitrogen before a repeated 50-second grinding program.
Low-temperature grinding of a difficult plastic sample
The experiment identifies JXFSTPRP-192CL and uses liquid-nitrogen pre-treatment followed by mechanical grinding to reduce clumping in a tough, heat-sensitive material.
Liquid-nitrogen grinding of PVA and silk fibroin
The experiment explicitly used JXFSTPRP-MiniCL-AUTO-N with automatic liquid-nitrogen filling and pre-cooling to process two tough polymer materials.
Cryogenic preparation of rat femur
The experiment identifies JXFSTPRP-MiniCL-AUTO-N and records a 20-minute pre-cooling step followed by five minutes of grinding for a bone sample.
Cryogenic grinding of ossified deer antler pad
The experiment explicitly identifies JXFSTPRP-MiniCL-AUTO-N with a 100 mL jar and documents liquid-nitrogen pre-cooling before repeated grinding cycles.
