Description
To prevent water and particles from entering your vacuum pump, replace your current 3/4″ hose with the new 3/8″ hose. Lyophilizers purchased between January 1, 2015 and November 30, 2019 can replace their current 3/4″ suction hose with the new 3/8″ hose. Be sure to check the fittings on your freeze-dryer (see image gallery) to make sure this hose is compatible. If you have a different fitting from the one shown, you’ll need to buy the pipe insert instead. With this upgrade, you only need to change your oil every 4 to 5 batches, depending on the quality of your oil. Freeze dryers shipped after December 1, 2019 (and all owners of oil-free pumps) should already be fitted with the new hose or hose insert. Call technical support if you have any questions about which one to order and/or whether it will work with your freeze-dryer.
