A funnel based on bivariate normal distribution is provided, and belongs to the field of daily tools. The funnel is formed by connecting a funnel body in a shape of a bivariate normal distribution with an outlet tube. The funnel body can be formed by rotating a normal distribution curve around the axis of symmetry z with a positive direction pointing to a deep part of the funnel, towards which the fluid flows. An outlet tube is a conical structure with a wide upper part and a narrow lower part. The surface of the funnel body has arbitrary order smoothness at everywhere. The design is simple and the fluid experiences little resistance when it flows through the inner surface. Thus, the funnel can effectively prevented blockage during the transport of fluid, powder and granules and the transport efficiency is remarkably improved.

A drain spout includes a tubular structure with threads on at least a first end for attaching to a small bunghole of a draining barrel. A process of draining material from the draining barrel includes screwing the drain spout into the small bunghole on the draining barrel. The draining barrel is aligned beside a catch barrel with the small bungholes of the barrels on the outsides and the two large bungholes side by side. The draining barrel is tilted with the drain spout towards the catch barrel and lifting the bottom of the draining barrel while inserting the second end of the drain spout into the big bunghole of the catch barrel. The draining barrel is rotated around the drain spout acting as the axis of rotation approximately 180 degrees until the lip of both barrels meet. The draining barrel is leaned back supported by the drain spout while draining.

A magnetic holder for a funnel or other tool has a tapered, cylindrical shaft. One or more arms extend from the shaft, with a magnets secured to the ends of the arms. The shaft has a wider opening on one end, and a narrower opening on the other end. The funnel or tool may be inserted into the wider opening, while the narrower opening may optionally be capped. The shaft may have interior ribs. The holder, except for the magnets, may be formed of a molded polymer. In use, the magnetic holder may be magnetically attached to a planar surface.

The present disclosure relates to an apparatus, method, and system for separating a fluid sample. The apparatus for separating a fluid sample may include a receiving chamber comprising a first opening and a second opening. The first opening may have a larger diameter than the second opening. The apparatus may include a channel extending from the second opening of the receiving chamber. The channel may include a proximal end adjacent the receiving chamber and a distal end. The distal end of the channel may bifurcate into a first branch and a second branch. The first branch and the second branch can be inserted into a first container and a second container through a cap having an orifice to separate a fluid sample into the first container and the second container.

A funnel system for attachment to a fluid reservoir. The funnel is telescopically expandable and include an adaptor that provides for attachment to a variety of different fluid reservoir openings. A snap cap is also provided that seals the fluid path when the fluid is not in use. In one embodiment, the funnel system is attached to the fluid reservoir for a prolonged period of time and functions to replace the stock cap on the reservoir.

A filling apparatus includes an upper hollow body having a top opening and a bottom opening; a first annular cylinder coupled to the upper hollow body via the bottom opening; a locking ring having a first keg lock slot and a second keg lock slot and coupled to the first annular cylinder; a second annular cylinder coupled to the first annular cylinder; a body seal ring coupled to the second circular cylinder; a bottom hollow cylinder coupled to the second annular cylinder and including a first vent opening probe, a second vent opening probe, and a probe divide wall. The filling apparatus can be connected to a valve on a keg, such as a Sankay-D valve, and can be used to pour alcohol and other liquids into the keg.
