Labbox Methylorange, solution 0.04 % 250 ml

This indicator solution is used in many professional laboratory environments to determine the pH value of samples quickly and precisely. Thanks to its uniform concentration and high-quality composition, it provides reproducible measured values and enables reliable evaluation. Compared to similar products, this solution offers a particularly clear colour response at defined pH ranges, allowing users to minimize misinterpretation or uncertainty.

Reliable properties for everyday laboratory work

The methyl orange indicator solution supports titrations, control measurements or screening procedures when it comes to differentiating between slightly acidic and neutral samples. Due to its precise composition, it is highly sensitive to pH changes and shows a clear color change even with small shifts. In professional environments, such as analytical laboratories in chemical, water and environmental technology, reliable and reproducible color development is essential in order to obtain meaningful results.

The most important technical data in brief:- Concentration: 0.04 %
– CAS number: 547-58-0
– EC number: 208-925-4
– Molar mass (MW): 327.34
– TARIC code: 38220000
– IMDG classification: 3 III UN 1993
– Brand: LABKEM

These details already provide a good overview of the nature and classification. The correct classification according to IMDG 3 III UN 1993 is essential for the shipment of liquid chemicals, as this allows specific transport and storage instructions to be followed. In addition, the molar mass of 327.34 provides valuable information for calculations in quantitative processes.

The color scale covered by methyl orange is particularly noticeable in pH ranges between around 3.1 and 4.4. The change from red in highly acidic environments to yellow in more neutral areas enables quick orientation in everyday laboratory work. For complex samples, for example water samples with small pH fluctuations, the clear and reliable color change usually leads to good differentiability. This allows users to determine exactly when the transition point is reached.

Thanks to its precise concentration, the product is versatile and can be seamlessly integrated into various titration protocols. This solution is ideal for both university courses and routine industrial analyses because it shows its color change efficiently even at low doses.

Relevant standards and safety requirements

Careful storage of the indicator solution is important to prevent contamination and loss of quality. Laboratories that work in accordance with DIN and CE specifications benefit from a clearly labeled solution that is classified as a hazardous substance. Hazard and danger warnings are based on the usual CLP regulations for chemicals of this type. Nevertheless, safe handling must be ensured by wearing appropriate safety equipment such as gloves, safety goggles and lab coats.

Examples of use

For various industries, there are specific scenarios in which the methyl orange solution shows its strengths:

– Acid-base titrations in chemical synthesis: ideal for determining the neutral point of samples with a slightly acidic character.
– Routine controls in water laboratories: For checking pH fluctuations in river and lake water samples.
– Education and teaching in the science sector: Demonstration of color changes in practical courses and laboratory exercises.
– Quality control in industrial companies: Rapid control of process stability during production, for example in manufacturing processes that require a certain pH value.

Common substances that are often tested in combination with this indicator solution include weakly acidic analytes such as acetic acid or nitric acid testing in the metal industry. In educational and research institutions, the product is also used for various samples with a wide range of organic and inorganic components.

FAQs

How long is the shelf life of the indicator solution?

When stored properly in accordance with the recommended conditions (e.g. cool, light-protected environment), the indicator solution generally remains stable for a period of several months to one year. More detailed information can be found on the label.

Can the methyl orange solution be reused?

In principle, no. Once used, the indicator solution may be contaminated by sample residues or chemical reactions. To ensure accurate results, fresh solution should always be used.

Is the solution suitable for highly alkaline or strongly acidic samples?

Methyl orange shows the most accurate color change in the slightly acidic pH range. For highly alkaline or very strongly acidic samples, other indicators with a corresponding color range are often more suitable.

How do I dispose of the indicator solution after use?

Disposal should be carried out in accordance with local regulations for chemicals. Disposal via an approved specialist company for hazardous substances is usually recommended.
