Abstract: Serum is reacted with a dinitrohalobenzene compound and the rate of halogen formation is measured. This rate is in proportion to the amount of albumin in the sample. Other proteins like the globulins, as well as free aminoacids and urea, do not interfere with this reaction.

Abstract: A tablet dispenser is described for dispensing tablets from individual packets into a small reaction chamber without contamination. The dispenser has a top shaft, and a thumb piece in which a cutting blade is engaged, the thumb piece being slidably mounted on the shaft. There is also provided a plate having a hole adapted to allow the blade to pass therethrough, the plate being connected to the top shaft by a support member, and a bottom shaft extending underneath the hole and in line with the cutting blade and top shaft. The bottom shaft is connected to the plate. Also provided is a clip for holding a package containing a tablet on top of the plate so that the package can be positioned to align the tablet over the hole and in the non-cutting path of the blade. When the thumb piece is depressed the tablet is released from the package and falls down the bottom shaft and into a reaction vessel placed below the bottom shaft.
