38-400 Silicone Lined Caps

Silicone Lined Polypropylene Caps (38-400)

SKU: CPSL 15-100-19

Silicone lined polypropylene 38-400 caps are designed specifically to meet the demands of homogenizing in 15 ml and 50 ml polycarbonate vials.  The caps are lined with a thick 3/32" silicone disc that prevents cracking, even when larger grinding balls are used.  The caps firmly seal vials, preventing leakage, and can be used both cryogenically or at room temperature.
These caps are designed for homogenization vials, but can be used with any 38-400 bottle or vial.  
Available in bags of 100 each.
