Reagecon's Ammonium Thiocyanate 0,1 M according to Chinese Pharmacopoeia (ChP) is a fully factorised, high purity, stable product, developed and tested for titrations. This is an Analytical Volumetric Solution, also called titrant, standard titrant or standard solution. It is a reagent of known concentration, that is dispensed from a burette or other dispensing apparatus to a sample (analyte), until a reaction between the two liquids is judged to be complete. The product may be used for manual titrations, or more commonly automatic titrations also called potentiometric titration, to determine the end points by detection of any of several properties as detailed in several ChP monographs.

Indicator tablets for determination of water hardness by titration with EDTA.

Specifications
Minimum weight: ≥ 0.20 g
Maximum weight: ≤ 0.23 g
Disintegration time (at 25°C): ≤ 150 s
Application test: conforms

The tablets are dissolved in 100 ml of the water sample to be tested, which has been buffered at pH 10 with 1 ml of Ammonia/ Ammonium chloride buffer solution, and then titrated with EDTA solution (0,01 M) till the sample turns from red to blue.
Total hardness in mg/l = 10×ml of titrant used.

Control samples of  calcium carbonate should be used to calibrate the method.

Reagecon's Tetrabutylammonium Hydroxide 0.1M is a fully factorised, high purity, stable product, developed and tested for titrations. This Analytical Volumetric Solution, also called titrant, standard titrant or standard solution, is tested to a specification of ± 0.2%. It is a reagent of known concentration, that is dispensed from a burette or other dispensing apparatus to a sample (analyte), until a reaction between the two liquids is judged to be complete.

Supplier: Lovibond

The speed test is based on reverse titration. After adding a reagent tablet to a calibrated test tube, the water sample is added slowly until the colour of the solution changes (e.g. from red to blue). The user can then obtain the result from the liquid level.

Supplier: VWR Collection

Digitrate Pro™ combines modern design, with precise, accurate and convenient dispensing. Its head can be conveniently rotated 360° for operator safety and comfort, whilst the see-through barrel ensures bubble-free titration. The robust outer casing does not move during priming or dispensing sequences, and the PTFE plunger and borosilicate glass barrel allow dispensing of aqueous solutions and some aggressive liquids.

Supplier: Hach

This kit is used for controlling boiler and cooling water treatment and checking corrosion using the drop count test which is a simple volumetric/ titration method with colour indication. It is an economical solution for the small boiler operator who needs to monitor alkalinity (5 to 400 mg/L), chloride (5 to 400 mg/L), hardness (0 to 2500 mg/L), iron (0 to 4 mg/L), and pH (4 to 10).

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.
