What kind of tubing is used for peristaltic pump?

Silicone
Silicone is the most commonly used peristaltic pump tubing. It has the longest service life and good chemical compatibility for aqueous and many organic solvents and is often used on the Sulfate chemistry which contains alcohol.

Is PVC air permeable?

Polyethlyene and PE/PVC tubing have very low air permeability, but are not ideal for implantation.

How do I choose tubing material?

The key is to select tube material which is softer than the tube fitting material. For example, Stainless Steel tubing should be specified as Rb 80 or less hardness value. Parker A-LOK® / CPI™ Tube Fittings have, however, been tested on tubing up to Rb 90 hardness level with excellent performance.

What is PharMed tubing made of?

PharMed® BPT is a polypropylene-based thermoplastic elastomer (TPE) which is opaque beige in color. It remains flexible and stable at temperatures between -40 and 135 °C, and meets the requirements of United States Pharmacopeia Class VI.

What is Norprene tubing?

Norprene® Chemical Tubing is a high performance co-extruded product specifically formulated to provide an ideal combination of chemical resistance and pump life. Norprene® Chemical Tubing is an excellent choice for sensitive fluid transfer applications.

What is the permeability of PVC?

In recent years, PVC tubing has replaced rubber hoses, but even PVC has a fairly high moisture permeability coefficient, at 275.

What is PE tubing?

Poly tubing, often referred to as PE tubing or polyethylene tubing is a flexible, lightweight, durable and corrosion resistant plastic that can be used for a wide range of liquid, gas and fluid transfer applications. Polyethylene tube is completely safe and is one of the most common PE tubing materials in the world.

What is tubing material?

Tubing material defines most of the structural and chemical properties of the tube. Materials include metals, plastics, and various other types.

What is PVC tubing?

Polyvinylchloride (PVC) tubing is a clear and flexible tubing that is resistant to many chemicals. It is manufactured from quality resins that are non-toxic and its smooth interior and exterior prevents sediment accumulation and makes it impervious to bacterial action.

What is C flex tubing made of?

thermoplastic elastomer
C-Flex tubing is manufactured from pharmaceutical-grade thermoplastic elastomer, is fully characterized, validated and tested to a variety of specifications.

What is PharmaPure tubing?

PharmaPure® is a premium, low spallation, biologically compatible peristaltic pump tube developed especially for pharmaceutical, biotechnology and laboratory applications. This tubing meets the challenges of providing unsurpassed pump life with ultra-low particulate spallation and very low permeability.

What is the best material for a peristaltic pump?

It is an good choice for long term peristaltic pump applications because it offers excellent flex fatigue and good tear resistance. Grayline MD65-TPE is a clear flexible tubing made from a high purity grade TPE compound.

What is the hardness of peristaltic pump tubing?

Peristaltic pump tubing is generally between 50 – 65 Shore A hardness and often sold with very tight tolerances on the ID and wall thickness. Since the tubing is the only surface that the fluid is exposed to, the chemical compatibility chart included with this report provides a good way to narrow down the material options.

What are the characteristics of peristaltic tubing?

The tubing is soft, pliable, and contains no plasticizers which could leach out, causing flow contamination. It is odorless, tasteless, inert and is ideal for use in both continuous and intermittent peristaltic pump applications.

How does a mechanical peristaltic pump work?

The mechanical peristaltic pump is made up of a few simple components that combine to form a positive displacement pump. An electric motor provides power to a roller which rotates and squeezes flexible tubing along the pump casing.
