Customer Questions & Answers
-
Question:
What are stonylab Watch Glasses used for?
Answer: Stonylab Watch Glasses are primarily used as covers for beakers and evaporating dishes in laboratory settings. They help in preventing contamination of samples by keeping dust and other particles away. Additionally, these glass covers can aid in the evaporation of solvents while also allowing for temperature observation. They're particularly useful in chemistry and biology labs for experiments that require open containment. -
Question:
What material are stonylab Watch Glasses made from?
Answer: Stonylab Watch Glasses are made from high-quality borosilicate glass, known for its exceptional thermal resistance and durability. This material can withstand temperature changes without cracking or breaking, making it suitable for various laboratory applications. The ground edge design enhances safety, reducing the risk of chipping. Borosilicate glass is also chemically inert, ensuring that it won't react with the substances being studied or contained. -
Question:
How do you properly clean and maintain watch glasses?
Answer: To maintain stonylab Watch Glasses, you should gently wash them with warm soapy water and a soft cloth or sponge to avoid scratches. Rinse thoroughly to remove any soap residue. For tougher stains, a diluted solution of hydrochloric acid or acetone can be used, followed by washing. Ensure they are dried completely before storage. Proper maintenance prolongs the lifespan of the glassware and ensures clean experiments. -
Question:
Are stonylab Watch Glasses suitable for microwave use?
Answer: Yes, stonylab Watch Glasses made from borosilicate glass are generally safe for microwave use, owing to their ability to withstand high temperatures. However, it is important to avoid sudden temperature changes, as this can cause thermal shock. Using these glasses in the microwave is beneficial when you need to heat contents uniformly while preventing splattering, making them ideal for laboratory protocols. -
Question:
What are the dimensions of the stonylab Watch Glasses?
Answer: The stonylab Watch Glasses each have a diameter of 150 mm. This size is compatible with various standard laboratory beakers and evaporating dishes, making them versatile for multiple applications. Their ample surface area ensures adequate coverage, contributing to effective sample handling and minimizing contamination during storage or transportation. -
Question:
Can stonylab Watch Glasses be used in a fume hood?
Answer: Absolutely, stonylab Watch Glasses are ideal for use within fume hoods. They provide a safe covering for chemical reactions that may emit vapors or fumes, thus protecting laboratory personnel. Their transparency also allows easy observation of the process underneath, aiding in monitoring reactions safely within a controlled environment. -
Question:
How many watch glasses are included in the set?
Answer: The stonylab Watch Glasses set includes ten pieces, making it a practical choice for laboratories that handle multiple samples or experiments. Having multiple glasses ensures you can work on several processes simultaneously without the need for frequent washing. This is particularly useful in educational settings or research laboratories where efficiency and cleanliness are paramount. -
Question:
What is a practical use case for stonylab Watch Glasses?
Answer: An effective use case for stonylab Watch Glasses would be in a laboratory conducting evaporation experiments. By placing a watch glass over the beaker, you can observe the evaporation process without exposing the contents to atmospheric contaminants. This method is ideal for studies involving volatile solvents, helping maintain sample integrity while achieving your experimental goals. -
Question:
Are these watch glasses stackable for storage?
Answer: Yes, stonylab Watch Glasses can be stacked securely for storage due to their flat, circular design. This feature saves space in laboratory storage cabinets and helps in keeping your workspace organized. Stacking them also minimizes the risk of breakage when properly handled, ensuring they remain in excellent condition for laboratory use. -
Question:
Where can I buy stonylab Watch Glasses in Ethiopia?
Answer: You can purchase stonylab Watch Glasses at Ubuy in Ethiopia. Ubuy offers a wide selection of laboratory supplies, including the 10-pack of stonylab Watch Glasses, making it a convenient option for educational institutions, research facilities, and individual buyers looking for quality lab equipment.
