For labs using solvents incompatible with polycarbonate, the 24 Well PE Vial Sets are a practiced alternative.  Resistant to many solvents that melt polycarbonate, these cost effective PE Vial Sets are suitable for most small seeds and animal tissue.  PE vials are relatively pliable compared to polycarbonate vials and are not as effective when used on large, hard samples like corn kernels. 10 vial sets/case, 240 vial sets total. Case complete with 240 lined caps.
