Centrifuging, Storing, and Quantitative Dispensing of Micro Samples; an Improved Technic.

In an adaptation of standard technics and apparatus, aqueous homogenates from single rat lenses are introduced into capillary tubes, soluble and insoluble constituents are separated using a micro hematocrit centrifuge, and samples are frozen and stored in the capillary tubes. To allow quantitative transfer of sample aliquots from these capillaries for chemical and immunologic determinations, commercial micro titrator was modified.
