These 15 ml vials are ideal for homogenizing larger samples, such as 1-3 gm of animal tissue or plant leaves. The silicone lined cap prevents leakage, but is designed for cryogenic grinding. Unlined caps, which can also be used for cryogenic grinding, normally crack and are discarded and replaced after cryogenic grinding. The silicone lined caps contain a thick silicone liner that prevents cap breakage. Thus both the vial and lined caps are extremely durable.
Each case comes complete with 100 polycarbonate vials and 100 silicone lined, deep polypropylene caps. These vials can work with any size grinding ball up to 7/16". Both the caps and vials can be autoclaved.
