Spectra/Chrom® Laboratory Tubing

Related Items

Tubing Box Spectrum Chromatography manufactures tubing in all of the popular sizes from all of the most used materials, including silicone, vinyl, Teflon, and high density polyethylene. Tubing made from the softer materials (vinyl, silicone, and a novel, soft fluoroplastic) are suitable for use with peristaltic pumps. All of the tubing products we manufacture can be regarded as general laboratory tubing.

For convenience, all tubing length longer than 3 meters (10 feet) are packaged in easy-to-use shelf dispenser packs. These packages minimize your shelf space requirements and allow you to easily see which tubing products are available. Each package also includes a Spectra/Chrom® tubing cutter; this cutter makes square, even, cuts in most laboratory tubing providing better connections with less chance of leakage.

The most common tubing sizes and material for use with peristaltic pumps, including the Spectra/Chrom® pumps, are described at http://www.spectra-chrom.com/pertube.htm.

The available sizes and materials of general laboratory tubing are described at http://www.spectra-chrom.com/labtube.htm.

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 on the 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 live 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 on the wet cycle.

Teflon Tubing (HPT). Teflon is the most inert of all the tubing we manufacture. It 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. However, it should not be used for fluid transport until it has cooled.

Polyethylene Tubing (HPP). Polyethylene tubing is an inexpensive alternative to Teflon tubing. Like Teflon tubing, polyethylene can handle pressure significantly higher than any of other flexible tubings. Polyethylene does not have the thermal stability of Teflon so it should not be autoclaved; it can, however, be sterilized ethylene oxide.


Spectra/Chrom Tubing Cutter

The Spectra/Chrom Tubing Cutter cuts most polymer tubing, leaving a flat, even edge. The special "V" shape of the tubing holder keeps the tubing perpendicular to the blade. The blade remains sharp for many cuts, but it can easily be replaced.

The Spectra/Chrom Tubing Cutter can be used on most flexible tubing 1/2" (13 mm) OD or smaller. It is not for use on metallic tubing. Use part number 123367 for the tubing cutter and 123368 for a package of 5 replacement blades.


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 Teflon tubing.
