Triethanolamine Hydrochloride, Reagent is a strong base and is as a complexing agent for aluminum ions in aqueous solutions. This reaction is often used to mask such ions before complexometric titrations with another chelating agent such as EDTA. The Reagent grade denotes that this chemical is the highest quality commercially available and that the American Chemical Society has not officially set any specifications for this material. Spectrum Chemical manufactured Reagent grade products meet the toughest regulatory standards for quality and purity.

Zincon is a colorimetric indicator for Zn, Cu and Hg. Reagent for the spectrophotometric determination of zinc. Simultaneous determination of zinc and copper. Used in automated flow injection analysis of zinc. As a metal indicator for EDTA titration of Zn, or for the back titration of Ca in the presence of Mg with glycoletherdiaminetertraacetic acid (GEDTA or EGTA).

Supplier: CHEMetrics

Ceric sulfate is the titrant and ferroin is the end point indicator. The method is free from glycol interference in samples that contain up to 75% glycol, making it particularly applicable to systems that contain nitrite corrosion inhibitors. Results are expressed as ppm (mg/L) NaNO2.

PIPES is a zwitterionic N-substituted aminosulfonic acid "Good" buffer.
PIPES is used to buffer glutaraldehyde fixative solutions when fixing plant and/or animal tissue samples. This will help prevent the loss of lipids. It is also used to buffer glutaraldehyde and formaldehyde when fixing fungal zoospores for fluorescence microscopy and electron microscopy. PIPES tends to give optimal results.
Buffers can be made by adding a solution of base to PIPES free acid, titrating to the appropriate pH.

Glutaraldehyde is also referred to as glutaral, 1,5-pentanedione, potentiated acid glutaraldehyde, sonacide, and glutardialdehyde. Pure monomeric glutaraldehyde has an absorbance peak at 280 nm and the main impurity, possibly a polymer, has an absorbance peak at 235 nm. Upon analysis, this product is 25-28% by titration and has an A235/A280 ratio of not more than 0,5. Monomeric glutaraldehyde may be purified from polymeric glutaraldehyde by treatment with charcoal (5% w/v) and subsequent filtration (3-4 times). Untreated glutaraldehyde has an absorption at 235 nm that is 5 times greater than that at 280 nm, whereas, after three washings the values are about equal. Glutaraldehyde is a bifunctional cross-linking reagent, reacting with NH2 groups to form Schiff's bases.
