The apparatus comprises a levelling mechanism having an upwardly directed reference surface adjustably mounted on a frame for supporting the base of liquid sample containers in substantially level orientation. The apparatus further comprises a container positioning member having a horizontally extending main body formed with a plurality of substantially vertical container- receiving sockets. These sockets are each open at their bottom ends, so as to allow the bases of liquid sample containers to project therethrough while held within the sockets adjacent their top rims. In this manner, when the container positioning member is placed down upon the levelling mechanism, the bases of the sample containers come to rest in contact with the reference surface. Such action levels the containers to facilitate accurate automated volume measurements of liquid samples within the containers to be taken, which accuracy, in turn, increases the accuracy of automated particle counts subsequently made with the liquid samples. |
