Watch Glasses for Chemical and Biological Laboratory

Although the name "clock glass" refers to the covers used in old timepieces, the current watch glass is the foundation of any laboratory's equipment. This characteristic, convex vessel is made of high-quality glass with high chemical resistance, thanks to which it easily withstands contact with acids or alkalis. Depending on the specifics of the work, scientists can choose from models with a diameter of 40 to 180 millimeters, perfectly matching the size to specific tasks.

The versatility of this accessory allows it to be widely used in many research processes, such as:

• evaporation of small amounts of liquids,
• precise weighing of loose reagents,
• tight covering of beakers and other vessels,
• protection of the contents against dust and vapor escape,
• ongoing observation of chemical reactions,
• preparation of samples for microscope.

The transparent structure makes it easy to monitor processes, and the specific shape makes the slide an indispensable element of everyday work in any professional laboratory.

Proper adjustment of the size of the slide to the opening of the vessel makes everyday work not only more comfortable, but above all safer for the user. By choosing Labglass and Isolab products, you get a guarantee of durability and reliability, which is essential in any professional laboratory.

Quartz watch glasses with high thermal resistance

Megan watch glasses are specialized laboratory vessels designed to work in extreme conditions. Made of pure silica, they are extremely resistant to high temperatures and rapid thermal changes, which completely eliminates the risk of cracks during sudden cooling of the material.

Megan watch glasses are: 

• available in six variants - with diameters from 40 to 100 mm,
• full chemical inertness - guaranteeing the safety and purity of analyses,
• high resistance to direct contact with nitric and sulfuric acid,
• the possibility of safe use in sample combustion processes,
• ideal properties for intensive crystallization processes.

In contrast to traditional solutions, these products focus on maximum durability in aggressive environments. Thanks to their unique structure, Megan accessories become an indispensable piece of equipment in any modern laboratory, ensuring precision and safety during the most demanding research work.

Watch glasses for liquid evaporation and crystallization

Watch glasses are versatile laboratory tools. Thanks to their unique design, they combine functionality with high precision. Their concave shape and perfectly smooth surface make them an excellent alternative to traditional steamers in everyday research work. The benefits of their use include:

• more efficient evaporation of liquids and free crystallization of substances,
• easy collection of the resulting sludge without the risk of contamination of the sample,
• effective protection of the contents of dishes against dust and vapor escape,
• constant observation of the reaction - possible thanks to the use of chemically resistant glass,
• precise weighing and transfer of bulk materials to the flasks,
• Stable base for microscopic analysis of preparations in suspension.

The high transparency of the material guarantees a clear image under the lens, and the smooth structure prevents the substance from sticking, which is crucial for maintaining sterility and cleanliness of the conducted research. Thanks to their resistance, these slides ensure safety and repeatability of results in any laboratory.

Lids for beakers and laboratory crystallizers

Watch glasses are irreplaceable laboratory accessories that act as precise covers for beakers. They effectively protect the contents from external contaminants and significantly reduce the evaporation of liquids, which is crucial for maintaining constant parameters of solutions. Thanks to the crystal clarity of the glass, the user can freely monitor the course of the reaction without having to uncover the vessel.

Their additional advantages include:

• precise weighing of loose substances without losses,
• allowing sterilization, high temperature resistance,
• excellent optical parameters, eliminating distortion,
• Availability of many diameter variants to match the dishes.

The smooth surface of the material prevents particles from sticking, which makes it easier to carry the test material. In microscopy, the concave shape of the slides protects the stage of the device from accidental spillage, and the high durability ensures that the product retains its clarity even under heavy use. It is an ideal choice for laboratories that value occupational hygiene and precision measurements.

Bulk Chemical Weighing Stands

Watch glasses are an extremely economical solution that effectively replaces traditional weight vessels. Their perfectly smooth surface allows for precise transfer of bulk substances, which is crucial for obtaining solutions with accurate concentrations. Thanks to a wide range of diameters, the product can be perfectly adapted to any laboratory balance pan.

When working with a stereoscopic microscope, the slides act as stable stands, and their concave profile effectively protects the device stage from accidental spillage. The use of high-quality raw material guarantees a crystal clear image without distortion, which allows for comfortable observation of details even when examining aggressive substances.

Their most important advantages include:

• An economical alternative to weighing vessels
• perfectly smooth surface for easy dispensing,
• a wide selection of diameters to match the scales,
• effective protection of the table against flooding,
• crystal clear image without distortion,
• high resistance to chemicals.

Slides for observation of specimens under a stereoscopic microscope

Watch glasses are the foundation of working with a microscope, offering a stable platform for insightful research observations. These are key accessories used in the analysis of soil samples, minerals and small organisms. They create a neutral background that allows the researcher to fully concentrate on the structure and details of the object being analyzed.

The use of these laboratory vessels brings a number of practical benefits:

• stable platform for precise observations,
• neutral background for the examined details,
• concave structure that effectively retains liquid,
• crystal clear glass structure,
• perfectly smooth surface for easy handling,
• Effective protection of the microscope stage from moisture.

The concave shape of the slide prevents spillage, which helps to maintain workplace hygiene. The high quality of the material provides excellent visibility, and the smooth surface makes it easy to manipulate the preparations precisely with tweezers. Choosing professional accessories is about ensuring the safety and durability of your optical equipment.
