Latex rubber tubing with 5/16 inch (about 8 mm) inner diameter and 1/16 inch (about 1.5 mm) wall thickness for use in laboratory, machinery, agriculture, pharmaceutical, automotive, and medicine. Applications for latex tubing include blood and fluid handling, peristaltic pumps, electrical and thermal insulation, analytical systems, intravenous solutions, and food and beverage handling. Tubing is extensively leached, washed and surface-treated to 99.9% protein-free. Seamless latex tubing which is free of striations lumen for clear passage of liquids and/or gases. The latex tubing’s translucency and uniformity of color provides an unobstructed observation of liquid flow line. It has impressive gripping power which enables the tubing to grip tenaciously to connectors. When you order more than 10 feet you may receive the product in multiple segments. Maximum length of continuous tubing is about 20 feet.

Clear plastic tubing made of Polyvinyl Chloride is colorless, tasteless and non-toxic. It lasts 15 to 20 times that of rubber and it has excellent age resistance qualities. Highly resistant to oils, acids, alkalies. Can be safely used in the conveying and processing of food stuffs. PVCTUBE is not affected by bacteria and has very low water absorption. Can be steam-sterilized at 20 Lbs steam pressure for 15 minutes. PVCTUBE should not be exposed to aromatic-hydrocarbons, ketons or esters for more

This dialysis tubing has a diameter of 49 mm. When closed, the strip is 77 mm tall and the length is 10ft. Dialysis Tubing is a semi-permeable membrane created from a natural source of cellulose. It allows passage of particles up to 14,000 molecular weight standards.
