Abstract
A laboratory article, and in particular a cluster plate is provided including a plurality of wells supported by a structural framework including a peripheral wall. At locations in the structural framework a plurality of protrusions are provided so as to support the cluster plate on a support surface, such as a benchtop, in a point-to-point manner. Such point-to-point support allows the article to be moved across the support surface without the generation of unpleasant audible vibrations. According to a preferred embodiment, a cluster plate having protrusions extending from the lower edge of a peripheral wall is provided.
Claims23
An article comprising:
- a cluster plate having a peripheral wall forming a downwardly facing open space and having a substantially rectangular cross-section connected to a plurality of open wells and positioned so as to support said wells in spaced relation from a supporting surface, said wall having a lower edge;
- and
- a plurality of protrusions on said lower edge positioned to support said edge in spaced relation from said supporting surface for preventing audible vibrations of the peripheral wall when the plate is slid across a work surface.
A cluster plate designed to rest on a surface, comprising:
- a structural framework including a substantially horizontal connecting member having a plurality of open wells located therein, free-standing, substantially planar portions connected to said connecting member, said planar portions defining a peripheral wall of said structural framework and forming a downwardly-facing open space;
- and
- a plurality of protrusions on said plate positioned to support said substantially planar portions in spaced relation from said surface for preventing audible vibrations of the peripheral wall defined by the planar portions when the plate is slid across a work surface.
The cluster plate as recited in claim wherein said connecting member connects said wells to said peripheral wall, and wherein said structural framework further comprises reinforcing ribs extending between said peripheral wall and said connecting member or said wells.
A microchemical laboratory article designed to rest on a surface, comprising:
- a structural framework including a connecting member having a plurality of open wells located therein, free-standing, substantially planar portions downwardly extending from said connecting member, said planar portions defining a peripheral wall of said structural framework and forming a downwardly facing open space;
- and
- a plurality of protrusions on said peripheral wall positioned to support said substantially planar portions in spaced relation from said surface for preventing audible vibrations of the peripheral wall when the article is slid across a work surface.
