Peristaltic Pump Tubing

Glass Expansion supplies peristaltic pump tubing to suit most analyses. We have 2-tag, 3-tag and continuous tubing in a wide range of diameters and materials. We also supply the Contour range of flared-end pump tubing to facilitate the connection between the pump tubing and the sample capillary tubing.

Extend the life of your pump tubing

It is well known that peristaltic pump tubing wears out over time. You can slow the rate at which the pump tubing wears by lubricating the pump rollers with the EzyGlide cloth (Part number 70-EZG-CLOTH). This improves precision, reduces drift, and extends the period between recalibration.

Contour Flared-end Peristaltic Pump Tubing

It can often be quite difficult to insert the sample tube into the peristaltic pump tube. This is particularly so if the peristaltic pump tube has a small internal diameter (ID). An example is the pump tubing used for the internal standard which usually has an ID of 0.2 to 0.4mm and is incompatible with the sample tubing OD of 1/16". To facilitate this connection, Glass Expansion now supplies the Contour range of flared-end pump tubing. The flared end of this pump tubing allows the larger sample capillary tubing to be inserted.

Any of the pump tubing that we normally supply can be supplied with a flared end. This includes PVC 2-tag and 3-tag, Tygon MH 2-tag and 3-tag, Solva 2-tag, and Viton 2-tag. The flared-end tubing is supplied in packs of 6. See a list of available Contour Flared-end Peristaltic Pump Tubing.

CALCULATORS

Trident Dilution Factor Calculator

Do you need to:

  • Know how much your sample and internal standard are diluted?

Then check out the Trident Dilution Factor Calculator Below


Select Sample pump tubing:

Select Internal standard pump tubing:

Sample dilution result:

Sample is diluted by: %

ie final concentration of sample is times initial concentration

Internal Standard Dilution Result:

Internal standard is diluted by: %

ie final concentration of internal standard is times initial concentration

or Internal standard is diluted by a factor of

This calculation should be used as a guide only. Variations between pump tubes and roller pressures mean that the accuracy of the calculation cannot be guaranteed.

Pump Speed and Sample Uptake Calculator

Do you need to:

  • Choose the right pump tubing to give you the required sample uptake?
  • Select the pump speed to give you the required sample uptake?
  • Find out what the sample uptake is with the pump tubing and pump speed you are currently using?

Then check out the Pump Speed and Sample Uptake Calculator below.


Step 1 - Select the ICP model you are using or select “Other” to enter custom parameters.

Step 2 - Select the pump tubing you are using from the drop down box.

Your pump speed and sample uptake will automatically be displayed.

Optional: You can enter your required sample uptake to calculate the pump speed or enter your actual pump speed to calculate the sample uptake.

Just to let you know we're really pleased with the flared end tubing you supplied. It is far easier to use than standard tubing!!!! We've managed to eliminate all the little connectors we had in place too. I'm sure we'll be back for more when the need arises - delivery was incredibly fast and puts a lot of UK based suppliers to shame.

Your flared end pump tubes are the best idea since Kim Wipes!.

Wow, what a great idea! As an ICP analyst, the connection between the peristaltic pump tubing and the nebulizer has always been a problem.

I used an older version of the PE Online Internal Standard Addition kit for many years. ... I have found a similar kit offered by Glass Expansion to be a great improvement over the old PE kit. It has a glass T with friction-fit connections that are the same as the GE quick connect nebulizer fittings. They also provide flared-end peristaltic pump tubing that eliminates the problems you run into when trying to connect the narrow bore tubing.
