The **Labasics 840371335406 Borosilicate Glass Weighing Bottle (70 mL / 40 g)** is a precision-engineered laboratory accessory designed to meet the rigorous demands of analytical chemistry, pharmaceutical testing, and scientific research. Crafted from high-quality **borosilicate glass (Type I)**, this weighing bottle is renowned for its exceptional chemical resistance, thermal stability, and durability, making it ideal for applications involving aggressive solvents, acids, or high-temperature conditions. The robust construction ensures that it can withstand repeated use without warping, cracking, or leaching contaminants, which is critical for maintaining the integrity of experimental results. With a **70 milliliter capacity**, this bottle provides ample volume for accurate sample weighing while maintaining a compact, ergonomic design that fits seamlessly into standard analytical balances, including those with taring or direct weighing capabilities.
The bottle features a **smooth, ground-glass stopper** that seals tightly to prevent spillage and evaporation, ensuring sample stability during storage or transport. The stopper s precise fit minimizes dead space, reducing the risk of residue buildup a common issue with poorly sealed containers. The **clear, transparent borosilicate glass** allows for easy visual inspection of contents, enabling researchers to verify sample levels without opening the bottle, thus maintaining sterility and reducing exposure to airborne contaminants. Additionally, the bottle s **smooth, polished surface** facilitates effortless cleaning, as it resists staining and is compatible with a wide range of detergents, solvents, and ultrasonic baths, making it a low-maintenance yet high-performance tool for demanding laboratories.
Beyond its functional excellence, this weighing bottle adheres to **ISO 3585 and USP Class A standards**, ensuring compliance with international quality and safety regulations. Its **precision-ground edges** and **uniform wall thickness** contribute to consistent weighing accuracy, while the **neutral pH and inert nature** of borosilicate glass prevent interactions with sensitive samples, such as pharmaceuticals, biological materials, or volatile organic compounds. Whether used for **sample preparation, standard solution storage, or calibration purposes**, this weighing bottle delivers reliability and precision in every application. Its **universal compatibility** with most laboratory balances and its **long-term durability** make it a cost-effective investment for both academic and industrial settings, where accuracy and consistency are paramount.
**Pros and Cons of buying a Labasic 840371335406 Borosilicate Glass Weighing Bottle (70 mL, 40 pieces)**
### **Pros:** 1. **Durability and Chemical Resistance:**Borosilicate glass is known for its high resistance to thermal shock and chemical corrosion. This makes the bottle suitable for use with a wide range of solvents, acids, and bases without risking breakage or contamination.
2. **Precision and Accuracy:**Weighing bottles are designed to provide accurate measurements, which is essential in laboratories for precise dosing, weighing, and sample preparation. The tight-fitting caps help minimize spillage and evaporation, ensuring consistency in experiments.
3. **Versatility:**The 70 mL capacity strikes a balance between utility for small-scale experiments and practicality for routine laboratory tasks. The set includes 40 pieces, offering cost efficiency for labs or individuals who require multiple bottles.
4. **Compatibility with Analytical Equipment:**Borosilicate glass is often compatible with analytical instruments like balances, spectrophotometers, and other lab equipment that require glassware with low reactivity and high clarity.
5. **Sterility and Cleanliness:**Glass is non-porous, making it easier to clean and sterilize compared to plastic alternatives. This is particularly important in microbiology, chemistry, and pharmaceutical applications where contamination must be avoided.
6. **Long Lifespan:**High-quality borosilicate glass is less prone to wear and degradation over time, reducing the need for frequent replacements and contributing to sustainability.
7. **Compatibility with Autoclaving:**If the bottle is labeled as autoclave-safe (which is common with borosilicate glass), it can be sterilized using autoclaving, expanding its usability in sterile environments like hospitals or research labs.

### **Cons:** 1. **Fragility:**Despite its durability, glass is still more fragile than plastic or metal alternatives. It can shatter if dropped or subjected to sudden temperature changes, posing a risk of injury and potential contamination if broken.
2. **Weight:**Glass bottles are heavier than plastic ones, which can be inconvenient for frequent handling, especially in large quantities. This may lead to fatigue during prolonged use.
3. **Cost:**While borosilicate glass is durable, it is generally more expensive than standard glass or plastic alternatives. The upfront cost may be higher, though the long-term benefits may justify the investment.
4. **Limited Flexibility:**Unlike plastic, borosilicate glass cannot be easily modified or reshaped. If a bottle is damaged or needs to be altered for a specific application, it may not be repairable or adaptable.
5. **Potential for Static Charge:**Glass can sometimes generate static electricity, which may interfere with certain sensitive experiments or processes, particularly in electronics or pharmaceutical applications.
6. **Storage and Transportation:**Glass bottles require careful handling during storage and transport to avoid breakage. They may need protective packaging or additional precautions compared to plastic alternatives.
7. **Compatibility with Some Solvents:**While borosilicate glass is highly resistant to most chemicals, some highly aggressive solvents or extreme conditions (e.g., prolonged exposure to hydrofluoric acid) may still pose risks, though this is rare.

### **Ending Conclusion:**The **Labasic 840371335406 borosilicate glass weighing bottle (70 mL, 40 pieces)** is an excellent choice for laboratories or individuals requiring durable, chemically resistant, and precise glassware. Its advantages in terms of accuracy, cleanliness, and compatibility with a wide range of applications outweigh its minor drawbacks, such as fragility and weight. For most standard laboratory uses including chemistry, biology, and pharmaceutical work the benefits of borosilicate glass far surpass those of cheaper alternatives.
### **Recommendation:**If you prioritize **long-term reliability, chemical resistance, and precision** in your laboratory work, this weighing bottle is highly recommended. It is particularly suitable for:
- Routine weighing and sample preparation.
- Use with acids, bases, or organic solvents.
- Environments requiring sterility or high cleanliness standards.
However, if you frequently handle **extremely fragile materials, work in high-risk drop environments, or require lightweight alternatives**, you may need to weigh the pros and cons carefully. In such cases, consider using protective cases or exploring reinforced glass options.
For most users, the **Labasic borosilicate glass weighing bottle is a worthwhile investment** due to its durability, performance, and versatility in laboratory settings.
