I'm trying to set up experiments for keratin degradation and need pulverized/powdered hair. However, even freezing with liquid nitrogen followed by mortar and pestle grinding does not provide sufficient results. Is there any better/easier to apply way to grind hair? We do not have an automated bead milling machine, so nothing fancy please.
if you are trying thermal analysis, chopping hair to 1mm length gives good reproducibility
Hi, thanks for your answer. Do you cut the hair with scissors or something else? How do you get the specific length?
Thanks
Mortar and pestle grinding in liquid nitrogen, with the addition of pulverized glass.
For physical grinding, use a bead dispenser to load your vials and plates with your desired amount of beads.
Here is a bead dispenser that I work with. Also using a large number of samples. LabTIE also has a large variety of Bead dispensers, fitting tubes, vials, 96-well 384-well etc.

Try to feed hair fibers into your beard shaver grid holes while the shaver is working. I used this method to get few amount of almost powdered hair.
