Polyethylene vials, 4 ml, threaded with lined screw cap - 240 count

For labs using solvents incompatible with polycarbonate, our 4 ml Polyethylene Vials with Lined Polypropylene Screw Caps are a practiced alternative.  Resistant to many solvents that melt polycarbonate, cost-effective Polyethylene Vials are suitable for high throughput homogenization of most small seeds and animal tissue.  Polyethylene-Lined Polypropylene Screw Caps are recommended when wet grinding with buffers or solvents.

NOTE:  Polyethylene Vials are relatively pliable compared to Polycarbonate Vials and are not as effective when used on large, hard samples (e.g., corn kernels).  Polycarbonate Vials are preferred for cryogenic grinding.

Each 4 ml Polyethylene Vial has a working volume of 4 ml and is suitable for homogenizing up to 200 mg of sample.  Recommended for use with 3/8” Stainless Steel Grinding Balls and 5/16” Stainless Steel Grinding Balls (not included).

Sold in cases of two hundred forty (240) 4 ml Polyethylene Vials with Lined Polypropylene Screw Caps.
