Acomnroninstanceis whereavial is 'tobefpositioned withnavacuum llask'cont'a'ining a'freezinginii'xture thus tomaintain `the contents of' the vial lat a lovvtem'perature. To achievesuch-an yend,-experimenters commonly employ equipment suchl as ring stands, extension clamps an'tlfthe vlike'. Such -equipmentlserves'the purpose 'ibut is generally "cumbersome, expensive, and 'iineilicientt` tThe equipment is not adapted for situations where the vial must be maintained below the mouth of the larger vessel.

The device of this invention surmounts all the disadvantages enumerated above as will be evident from the following description.

l'eferring to Fig. l, the holder includes a plate of sprlngy sheet material, such as spring plate 1 of thin spring metal, on which is mounted arm 2 which extends generally normal to the surface of spring plate 1.

At the end of arm 2 is fastened a generally U-shaped member 3 the arms 4 of which are arcuate. A bridging member, in the form of a wire loop 5, extends between arms 4 of said U-shaped member 3.

An object-'receiving receptacle in the form of a cylindrical coil 6 made of spring wire is mounted within said U-shaped member, being positioned between 'arms 4 thereof. The size of coil 6 is so chosen relative to the distance between arms 4 that it snugly lits therebetween. In placing the coil within the U-shaped member 3, the coil vis rotated so that wire of which the coil` is formed threads past loop 5 which thereby forms a bottom abutment for the coil. This threading arrangement permits rotation of the coil for adjusting the length of the coil .extending above the U-sh-aped member.
