Spectrum Chromatography manufactures a complete set of instruments for liquid chromatography. These include Peristaltic Pumps, a Fraction Collector, a fixed wavelength UV Detector, a strip-chart recorder, and a Solvent Recycler.
All lengths of tubing longer than 3 meters are packaged in easy-to-use side access dispenser boxes to minimize your shelf space requirements. They also include a Spectra/Chrom tubing cutter which easily makes square, even, tubing cuts.
Silicone Tubing (LPS). This is the most commonly used peristaltic pump tubing. It provides the longest service life and good chemical compatibility for aqueous solvents. Silicone tubing can be autoclaved a single time using a wet cycle.
Vinyl Tubing (LPV). Vinyl tubing has the lowest per-foot cost of the available peristaltic pump tubings. It generally has only fair compatibility for most aqueous solvents and does not have a good tolerance for organic solvents. It has only about one-third the service life of silicone tubing in a peristaltic pump. Vinyl tubing should not be autoclaved or exposed to temperatures above 80°C.
Fluoroelastomer Tubing (LPF). Fluoroelastomer tubing is both the most chemically inert and the shortest lived peristaltic pump tubing. It can even withstand halogenated solvents for a limited time. Its service life is only about one-twentieth that of silicone tubing in a peristaltic pump. Like silicone tubing, fluoroelastomer tubing can be autoclaved a single time using a wet cycle.
FEP (HPT). FEP tubing is the most inert of all of the tubing we manufacture. It is made from a fluoropolymer (fluorinated ethylene-propylene) and can withstand nearly any solvent used in a modern laboratory, from distilled water to methylene chloride. It's excellent thermal characteristics allow it to be autoclaved repeatedly. After autoclaving FEP tubing should not be used for fluid transport until it has cooled.
Polyethylene Tubing (HPP). Polyethylene tubing is an inexpensive alternative to FEP tubing. Like FEP tubing, polyethylene can handle pressure significantly higher than any of other flexible tubings. Polyethylene does not have the thermal stability of FEP so it should not be autoclaved; it can, however, be sterilized ethylene oxide.
LPF is an abbreviation for low-pressure fluoroelastomer. This is a tubing which is flexible like vinyl tubing and yet has much of the solvent resistance of FEP tubing.
Our tubing cutter makes clean and square cuts in almost any plastic tubing 1/2" (13 mm) in diameter and smaller.
