Abstract: Disclosed herein are a method and system for determining an overall value rating or value estimate in relation to a product that is to be offered for sale or lease. The method includes the steps of identifying a product type associated with the product and determining a set of attributes for the identified product type. The method calculates a value score unit size for the product, based on statistical data relating to the product and the product type, determines an attribute value multiplier associated with each attribute in the set of attributes and presents an attribute template (130) to a seller associated with the product that is to be offered for sale or lease, the attribute template including the set of attributes. The method receives data from the seller in relating to each attribute in the set of attributes (140).

Abstract: A multi vessel ring (suitable for use with thermal cycler and PCR apparatus) comprises a ring body and a plurality of elongate tubes. Each tube has a proximal open end and a distal closed end, each elongate tube being integrally formed with the ring body, and being pivotally connected to the ring body between an initial position in which a longitudinal axis of each tube is generally parallel with an axis of rotation of the ring body, and a final position in which the longitudinal axis of each tube is inclined relative to the axis of rotation of the ring body. The multi vessel ring preferably further comprises a plurality of caps integrally formed with the ring body, and adapted to seal the proximal open end of respective tubes.
