Coupling element E1/E2M18/30, the “rubber star”.This wearing part connects the motor to the pump housing on your Edwards vacuum pump. Continuous exposure to heat and oil causes this coupling element to become brittle and fragile and must be replaced.OEM part number: 26501032Quantity: 1For Edwards E1M18, E2M18, E2M28 and E2M30 vacuum pumps.
For better separation in preparative Liquid ChromatographyEach parameter in the analytical LC is set and monitoredvery precisely. The temperature of the column is anessential factor for a good separation and is adjusteddepending on the problem and analytes. In the preparativefield, temperature control for columns has been thought of,but columns are only heated externally. For low flow ratesin the analytical field this might be sufficient, but forpreparative separations and high flow rates a lot ofefficiency is lost when the mobile phase is not heated.Lower mobile phase viscosityFaster interaction with stationary phaseLower system back pressureHigher flowrates without loosing resolutionShorter cycle timesEqualize the enthalpy of mixing solvents

Injection needle for 2690 and 2695 Alliance Separations Module and 717 AutosamplerQuantity: 1This needle is superior to all other needles. It is inert against acid, base and other solvents. The inner tube surface is passivated with HNO3. The 3µm Titanium Nitride layer protects the tip and surface from mechanical wear. TiN shows very low friction to the seals, this leads to a longer PM interval. We recommend to change the seals every two years or after 20.000 injections. As long as the needle has it´s golden surface it can be re-used. This needle is a long lasting investment.
This vacuum tubing made of marprene is suitable for replacing brittle vacuum lines in HPLC media degassers.Dimensions: 3.2mm ID x 6.5mm OD x 100cmFits most common vacuum degassers
