Tubing for peristaltic pumps is available in a wide range of sizes, from microfluidic tubing with a 0.13 mm inner diameter to industrial-grade tubing exceeding 25 mm ID for bulk transfers. Common tubing materials include Silicone (biopharma, sterile use), PharMed® BPT (biocompatible and long-life), Norprene® (industrial and chemical resistance), Tygon® (food and laboratory use), and PTFE-lined tubing (for aggressive chemicals). Choosing the right size and material ensures compatibility, durability, and safe operation.
