Good product for its purpose, but lacking in packaging
Characterisation of formic acid origin by means of 13C-NMR
Appropriate source of CO2 for the characterisation of the origin of formic acid (glucose degradation or CO2 reduction) in hydrothermal processing. Shipped in 5 g bottles. When I have tried to purchase more quantities (~100g), it was delivered in the same package, without any further discount, but due to research I needed it, so I couldn't avoid acquiring it. I guess that Sigma doesn't expect people to buy that much (even though my research requires so).

Sodium bicarbonate is broadly used as a physiological buffer in cell culture applications. The pKa for bicarbonate <-> carbonic acid reaction is 6.4 The pKa for bicarbonate <-> carbonate reaction is 10.3. Sodum bicarbonate has two pKas, 6.4 and 10.3. It is broadly used as an physiological buffer in in vitro applications.
