pH Combination Electrode





Fitted with coaxial cable and BNC (Bayonet Neill-Concelman) type SL-31 connector.

The combined Electrode consists of glass and reference electrodes in a single entity. Therefore a separate, reference electrode need not be used along with this electrode. Below the cap of the electrode a hole is provided for filling the solution in the internal reference electrode. The reference electrolyte solution or filling solution is a freshly prepared 2 M Potassium Chloride (KCl) Solution.

Preparation for Use

Soak the glass bulb and the fibre junction of the electrode in N/10 Hydrochloric Acid for 24 hrs to activate the sensing membrane. Then rinse the bulb with distilled water a number of times. Never use ordinary tap water.

Preparation of N/10 Hydrochloric Acid

Take 1 ml of concentrated Hydrochloric Acid and dissolve it in 100 ml of double distilled water.

Shake the solution inside the electrode to let it fall into the bulb. Fill the electrode with freshly prepared 2 M Potassium Chloride solution into three fourth.

Preparation of 2 M Potassium Chloride Solution

Dissolve 14.91 g of A.R. KCl in 100 ml of double distilled water and add a few crystals of A.R. AgCl

Instructions provided with electrodes.

Nessler Cylinders - 100 ml (pair) – Borosilicate Glass




Nessler Cylinders - a pair (2) - borosilicate glass.

Nominal capacity: 100 ml (brimful capacity about 150 ml).

Dimensions: height = 240 mm, outer diameter = 25 mm.

Two graduation marks, one at 50 ml, one at 100 ml.

Rimmed neck with pouring spout.

Brand: EROSE.

Uses:

Essentially a pair of sturdy and roomy test tubes, Nessler cylinders are typically used for manual (without spectrophotometer), quantitative colorimetry. For instance, in the case of the quantitative determination of ferric ions with their blood red ferric thiocyanate (rhodanide) complex, 50 ml of a standard solution of Fe3+ (in the 100 - 500 ppm range) plus indicator is loaded into one tube, and a known volume of sample solution plus indicator in the other tube. By standard addition or by dilution with water the solution colour of both Nessler cylindesr is then matched visually and the concentration of Fe3+ in the sample solution calculated.

Of course the cylinders can also be used simply as large, sturdy test tubes for general use.
