Director Sheryll Curtis explains the move to this new material: ‘PVC is one of our most popular tubing ranges, but we need to react to the increasing concerns about phthalates worldwide. We expect that phthalates will soon be banned under REACH regulation so by introducing this range now we are allowing our customers to make a smooth transition to the new product range’.
‘We have already received excellent feedback on the material – the general characteristics of PVC tubing have been maintained, including improvements to the pumping life, so this new tubing is a positive addition to our standard PVC ranges. The phthalate-free tubing is proving to be particularly popular with our customers in the pharmaceutical industry; the strong resistance to leaching of the components in the material being especially important in these applications.’
Phthalate-free PVC exhibits excellent acid and chemical resistance. It also has very low gas permeability and can withstand high pressure contents, making it a versatile tubing product. PVC tubing is transparent to allow the visual inspection of its contents, allowing the user to confirm that there are no interruptions to the flow.
Gradko have specialised in precision small-bore peristaltic pump tubing for the last 40 years and produce extrusion tolerances as low as +/-0.03mm in 0.13 – 2.79mm internal diameter tubing. The new phthalate-free tubing is available as 15m reels of transmission tubing as well as ready-assembled units of 2-bridge and 3-bridge tubing. Also included in Gradko’s range of phthalate-free PVC is Solva PVC tubing – specifically designed for use with solvents, aromatic oils and petroleum compounds. Solva PVC offers exceptional resistance to stomach acid and is therefore widely used in medical applications.
