A plant oil extractor includes a food grade tray with a removable lid that together define an evaporation chamber. A gaseous fluid pump has an inlet fluidly connected to the evaporation chamber and an outlet fluidly connected to an area outside of the evaporation chamber, which may be positioned in a freezer to recover condensed solvent leaving previously dissolved plant essential oil on the food grade tray. A vacuum sublimation freeze drying apparatus includes a container, which defines a drying chamber, is positioned in a freezer. A gaseous fluid pump has an inlet fluidly connected to the drying chamber and an outlet that opens outside the container. Water in fresh herbs positioned in the drying chamber initially freezes and then sublimates leaving behind freeze dried herbs.

A small needle tip cover is provided which is capable of rendering a used disposable needle safe from accidental punctures. The needle tip cover can take the form of a small rectangular piece of sheet metal that is bent back upon itself. The bend is shaped to provide a spring means which is operable to force the opposing sides of the cover together. The inner surfce of each side includes a plurality of serrated burrs which contact the shaft of a used needle and prevent the tip thereof from escaping. The needle tip cover is kept open by a collapsible column. Until the introduction of a used needle tip therebetween, the column is subject to failure from any slight transverse force, such as that provided by the shaft of the needle pressing there against.
