T UBI N G PolyE Polyethylene Tubing Harvard Apparatus’ PolyE polyethylene tubing is an excellent tubing choice for a variety of applications requiring small ID or OD tubing. It is available in both sterile and non-sterile packages. It can be used for infusions, tracheotomies or other surgical operations in rodents from mice to rabbits. Cross reference numbers to PE tubing is provided. Blunt probe needles can be used with this tubing to make custom cannulae. Information in the table will assist in needle selection. One column lists the size of needle which will fit into the tubing while the other column lists the size of needle through which each tubing size will pass.
