Polyethylene carriers with epoxy coated, heavy-gauge steel wire bails have wide ribs in both the sides and on the bottom to support and cushion bottles. The cone style lid has a 16mm (5/8") opening in the top for insertion of tubing to simplify the transfer of liquids without pouring. The truncated style lid permits pouring without the removal of the lid. These carriers are designed to hold standard US reagent bottles. Per each, 4 per case.
