Aquacides are useful for concentration of proteins and other macromolecules and can be used for rapid removal of water from dialysis tubing by using either a 2% syrup or the aquacide solid. Aquacides neither denature proteins nor change the pH during concentration. At room temperature 1 g of aquacide absorbs about 5 ml of water from solution in 1 h.

The SpinPrep™ PCR Clean-Up Kit is designed for the rapid purification of DNA amplified in PCR. This procedure involves addition of a binding buffer followed by adsorption of the DNA to a silica membrane in a spin column format. Following a wash step, the DNA is eluted in low-salt buffer. This kit removes DNA polymerases, dNTPs, salts, and > 99% of primers so that they do not interfere with downstream applications such as cloning, sequencing, or labeling. PCR products from 100 bp to > 12,000 bp can be cleaned up, with recoveries of amplified DNA in the range of 60-90% under standard conditions.

Chemizorb® Hydrofluoric Acid (HF) is a powder mixture consisting of a synthetic copolymer as the absorbent, a calcium salt as a neutraliser and precipitant, and a pH indicator. The neutralisation process results in the release of CO₂. When the hydrofluoric acid has been neutralised, the colour of the indicator changes from red to orange/yellow.

Supplier: MilliporeSigma

Desiccant suitable for desiccators to remove water, and for drying most gases and liquids (apart from strongly acidic and basic gases, organic solvents or alkaline liquids). The product contains iron salts as the indicator. The colour change is from orange to colourless at approx 7/10 g adsorbed H2O/100 g silica gel. Regeneration can be performed as often as required at 130 - 140 °C in a drying oven for three hours.

Hematoxylin monohydrate (C.I.75290) for microscopy Certistain®

Hämatoxylin-Monohydrat (C.I. 75290) Certistain® is a dye for the specific staining of DNA in the nuclei. It is used in cytology and histology. Nuclei are stained blue, dark violet to black. Hematoxylins are mixed with trivalent positively charged metal salts and build up the so-called hematoxylin lakes, used for the selective staining of nuclei (DNA). Certistain® is the quality group for seleceted high quality dyes that fulfill all quality requirements for IVD and CE registration.
