The invention relates to a one-sided mat, sealable, biaxially oriented polyester film with at least a base layer, a sealable cover layer and an additional mat cover layer, where the sealable cover layer has a minimum sealing temperature of 120\xb0 C. The plurality of pump cassettes may be symmetrically attached to the distribution tubing. When the rotor is stationary, the airgap between the magnets and the stator is at a minimum. At least a part of the second machine tool assembly is repositionable by movement along a second line that is non-parallel to the first line. In some example embodiments, a light source is employed that comprises a solid-state light source, e.
