Bromocresol green is a sulfonephthalein dye. It is mainly used for measuring serum albumin. In acidic conditions, bromocresol green interacts with albumin, thereby resulting in an increase in absorbance at 630 nm. The change in absorbance is linked with the concentration of albumin. Bromocresol Green is also a pH indicator, changing from yellow (pH 3.8) to blue color (5.4). It is widely used as a colloidal pigment.

Tissue samples may be snap frozen using PolyFreeze with isopentane and liquid nitrogen, dry ice (slush/slurry or bunker), or in a cryostat. PolyFreeze media do not cause autofluorescence and can easily be washed away during tissue fixation when rinsed prior to staining. Once rinsed off the slide, there is no trace of the support matrix to interfere with staining or immunohistochemistry (IHC) reactions.

Fluorinert™ belongs to the group of aliphatic compounds. It is considered as a pressure-transmitting medium because it is highly inert. Fluorinert™ Electronic Liquid FC-770 is a thermally stable, fully-fluorinated liquid that has ideal properties for use as a heat transfer fluid in a variety of industries. The inertness of Fluorinert™ FC-770 permits its use as a direct contact single and two-phase coolant in certain supercomputers and sensitive military electronics. Its high dielectric strength and electrical resistivity are ideal for applications in high voltage transformers and power electronics. In the semiconductor manufacturing industry, its wide liquid range makes Fluorinert™ liquid FC-770 suited for cooling ion implanters, dry etchers and CVD machines. Its low pour point also permits its use in thermal shock and test equipment.
