We encounter chemicals every day - in research, laboratories, technical applications and many industrial processes. But not every chemical is the same. Purity, production method, storage and quality play a decisive role. Anyone who buys or uses chemicals should therefore pay attention to their origin, quality and proper handling.
As a Swiss specialist store, mychem.ch offers a carefully selected range of laboratory chemicals, reagents and chemical solutions of proven quality. In this article, we explain what really matters when it comes to chemicals and why high-quality products are crucial.
The term chemicals covers all substances with a defined chemical composition. These include, among others:
- Acids (e.g. hydrochloric acid or lactic acid)
- Bases and alkalis
- Salts such as sodium chlorite
- Dyes and reagents such as methylene blue
- Various laboratory solutions and chemical compounds
- scientific laboratories
- industrial production processes
- technical applications
- Training and research
Many chemical substances are also important starting materials for other products and reactions. In laboratory chemistry in particular, precisely defined solutions are often used to achieve reproducible results.
The purity of a chemical is one of the most important quality characteristics. It determines how reliably a substance functions in chemical reactions or analytical processes.
- Technical quality
- Laboratory quality
- analytical quality
The higher the purity, the lower the proportion of undesirable by-products or impurities.
Impurities can:
- Influence chemical reactions
- Falsify measurement results
- Change the stability of a solution
It is therefore important to obtain chemicals from trustworthy sources. Precise production is crucial, especially for chemical solutions, to ensure that concentrations and properties remain constant.
Many chemicals are not only sold as solids, but also as ready-made solutions. The active ingredient is dissolved in a solvent - usually water - in a precisely defined concentration.
Typical examples are
- chemical reagent solutions
- Acid solutions
- Laboratory standards
- Dye solutions
A well-known example of such a chemical solution is CDS (chlorine dioxide solution). This is a diluted aqueous solution of chlorine dioxide gas that is produced under controlled conditions. To ensure stable quality, it is crucial that the production process is clean and the concentration is clearly defined.
- Precise dosing
- Suitable raw materials
- clean production conditions
- Sturdy storage containers
This is the only way to ensure consistent quality.
Storage also plays an important role in the shelf life and stability of chemicals.
Some important factors are:
Light protection
Many chemical substances react sensitively to UV light. This is why they are often stored in amber glass bottles or light-protected containers.
Temperature
Excessively high temperatures can accelerate chemical reactions and decompose substances.
Air contact
Some chemicals react with oxygen or carbon dioxide from the air. A well-sealed container prevents such reactions.
Clean containers
Laboratory bottles and reagent vessels should be chemically resistant and clean to avoid contamination.
In the case of sensitive solutions - such as oxidizing substances - careful storage can be crucial for stability and shelf life.
Basic safety rules apply when working with chemicals. These protect both the user and the environment.
The most important safety measures include
- Suitable protective equipment (e.g. gloves or safety goggles)
- Working in well-ventilated areas or under a laboratory chapel
- Correct labeling of chemicals
- Proper disposal
Many chemicals are safe to use if handled correctly, but require a responsible approach.
A growing trend is the purchase of chemicals from specialized stores that focus on high-quality products. These are particularly important:
- Transparent product information
- controlled raw materials
- Reliable packaging
- Careful storage
With mychem.ch the focus is on high-quality laboratory chemicals, reagents and chemical solutions. These include, for example, various acids, reagents, laboratory dyes and selected chemical solutions such as CDS (chlorine dioxide solution).
The range is aimed at users who value clean products, clear concentrations and reliable quality.
- Tested quality
- Clear declaration of the products
- Secure packaging
- careful shipping
When buying chemicals on the Internet, a few points should be taken into account.
Transparent product information
A reputable supplier will provide clear information on concentration, content and packaging.
Clean packaging
Chemicals should be supplied in chemically resistant containers that are tightly sealed.
Professional shipping
Shipping must be carried out in such a way that glass bottles and sensitive products can be transported safely.
Marking and labeling in accordance with regulations
The product labels must comply with the legal regulations and contain the corresponding inscriptions and warning texts as well as pictograms.
Experience of the provider
A specialized chemicals store has experience in handling chemical substances and their packaging.
Chemicals are important tools in science, technology and many technical applications. However, it is not only the substance itself that is crucial, but also its quality, purity and proper storage.
- more reliable results
- more stable solutions
- better shelf life
A specialist store with experience in handling laboratory chemicals is therefore the best choice for anyone who values quality and safety.
