Fluorescein can be purchased at Novohim’s online chemical shop.

In analytical chemistry

The dinatrium salt of fluorescein is used as a luminescent acid-base indicator in laboratory research.

In biochemistry and molecular biology

Sodium uranyl isothiocyanate derivatives are used as biological dyes for the detection of antigens and antibodies. Some halogen-substituted fluorescein, e.g. eosins, are also of practical importance.

Uranine for heating networks

Fluorescein is used in heating networks to detect water leaks. The dosage of uranine for this purpose is very small and amounts to 2-5 grams per 1 cubic metre of water.

It is added to closed heating systems and the water is coloured green.

The advantages of using pitchblende:

1. Reduction of unauthorised use of water
2. Quick identification of heating system breaks by coloured sweeps
3. Heat exchanger defects are coloured green

The basis for the use of fluorescein dinatrium salt – Standard Instruction on technical operation of heat networks of communal heat supply systems.

In the clothing industry

Sodium uranine is sewn into the fabric of life jackets when such a waistcoat falls into the water, a huge bright green stain is formed, clearly visible from an aircraft.

In medicine

In ophthalmological practice sodium fluorescein solution is used to diagnose

Physicochemical properties of uranine

The Sodium fluorescein/uranine message appeared first on Novohim.

It consists of circles cut from thick laboratory filter paper of special grades, treated with an acid mixture and free of iron. Red tape, like other filters, is 95% pure enriched cellulose. However, it has a filtering capacity or filtration rate of fifty seconds. This is a high level of performance. Also, the anhydrous filter is characterised by its convenience and ease of use. It is also highly resistant and ideal for filtering hot acidic, alkaline and neutral solutions.

Red tape filter application

In analyses and laboratory tests

The red ribbon filter is used for the separation of fine sediment for the subsequent accurate determination of the amount of sediment. Since these filters produce low amounts of ash due to thermal effects, they are used in routine gravimetric investigations for:

1. determination of the amount of insoluble impurities in various fats and oils
2. for the detection of insoluble suspended solids in process and drinking water
3. and to detect the presence and quantity of chemical and radioactive substances by gravimetry, precipitation, photo and colourimetry.

The red tape filter is used in scientific and research laboratories, enterprises:

• food
• defence
• electronic
• petrochemical
• pharmaceutical
• perfume industry
• jewellery industries
• as well as in the laboratories of various educational institutions.

The red tape filter is involved in the detection of components present in steels, iron, clays. As a primary filter it is used in soil analysis, for detection of solid precipitates in milk, for preparation of samples for atomic absorption spectrometry. It can also be used for the determination of radionuclides in air.

These are circles made of thick laboratory filter paper of special grades, treated with an acid mixture and free of iron. White tape, like other filters, is 95% pure enriched cellulose. However, it has a filtering capacity, or filtration rate, not exceeding forty-five seconds, which is moderate. It is also characterised by its convenience and ease of use.

White tape filter application

In analyses and laboratory tests

The white belt filter is used to separate coarse sediments such as:

• silver sulphides
• arsenic
• lead
• cadmium
• ammonium
• manganese
• iron
• lead chromate
• alkaline earth metal carbonates

and other substances, for the subsequent accurate determination of their quantities.

These filters are considered to be the cleanest filters as their ash content is minimal, allowing them to provide high accuracy in quantitative analyses. Since these filters produce low ash content due to thermal effects, they are used:

1. in routine gravimetric studies to determine the amount of insoluble impurities in various fats and oils
2. for the detection of insoluble suspended solids in process and drinking water
3. and to detect the presence and quantity of chemicals and radioactive substances by gravimetry, precipitation, photo and colourimetry

The white tape filter is used in scientific and research laboratories, food, defence, electronics, petrochemical, pharmaceutical, perfume, jewellery manufacturing and in the laboratories of various educational institutions.

The white tape filter is ideal for the detection of sand in foodstuffs, in paper production and in the quality control of aqueous suspensions.

It consists of circles cut from heavy laboratory filter paper of certain grades, treated with an acid mixture and free of iron. This filter is 95% pure enriched cellulose. It also has a filtering capacity, or filtration speed, of one hundred seconds. It is characterised by its convenience and ease of use. In addition, with its increased stability, it is ideal for filtering hot acidic, alkaline and neutral solutions.

Filter blue tape application

In analyses and laboratory tests

The blue ribbon filter is used for the separation of fine sludge for the subsequent accurate determination of the sludge quantity. Since these filters produce low amounts of ash due to thermal effects, they are used:

1. in routine gravimetric studies to determine the amount of insoluble impurities in various fats and oils
2. for the detection of insoluble suspended solids in process and drinking water
3. and to detect the presence and quantity of chemical and radioactive substances by gravimetry, precipitation, photo and colourimetry.

The blue ribbon filter is used in:

• scientific and research laboratories
• food, defence, electronics, petrochemical, pharmaceutical, perfume industries
• jewellery industries
• as well as in the laboratories of various educational institutions.

In the practice of chemistry

You can buy phenolphthalein in Ukraine in the online shop of chemicals Novohim.

Due to the ability of this indicator not to react to high temperatures, it is often used to react with alcohol solutions. Phenolphthalein is widely used in chemistry for titration of aqueous solutions.

It is an acid-base indicator. Due to its amazing chemical properties, it is often a constituent of various mixed indicators. It is very popular for calorimetric calculation of acidity levels using buffered and unbuffered solutions.

In medicine

It was previously used as a laxative, but recent studies have shown the possible carcinogenic properties of phenolphthalein, which is not good for the elderly and pregnant women.

In metallurgy

The indicator is used to spray zinc, lead, magnesium and cadmium to achieve excellent colouration.
