When sectioning frozen tissue for rapid surgical biopsy diagnosis or for research (typically in Histochemistry), the tissue sample must be firmly attached to the microtome stage or chuck. Embedding material such as OCT are preferred as these also provide a supportive and protective aid to sectioning.

In 1976, Guilbert and Iscove demonstrated that precursor cells of erythrocytes and macrophages could be cultured in a reduced-serum medium supplemented with albumin, transferrin, lecithin, and selenium. Iscove's medium is a modification of Dulbecco's Modified Eagle's Medium (DME) containing selenium, additional amino acids and vitamins, sodium pyruvate, HEPES buffer, and potassium nitrate instead of ferric nitrate. Further studies have demonstrated that Iscove's medium will support murine B lymphocytes, haemopoietic tissue from bone marrow, B-cells stimulated with lipopolysaccharide, T-lymphocytes, and a variety of hybrid cells.

Specifically designed for rapidly cleaning 7000 series modified Microliter™ syringes, this syringe cleaner also effectively cleans Microliter™ and Gastight® syringes. A combination of heat (approximately 370 °C) and vacuum vaporises and extracts contaminants from the needle. The syringe cleaner is ineffective for septa-plugged needles, seised plungers and other irreparable needles.
