( Brand: Kimble Kimax ), ( Manufacturer Part Number: 20024-500 ), ( Part Type: Cylinder Scale )
The **Kimble Kimax 20024-500 Glass Graduated Cylinder with Threaded (TD) Hex Base** is a precision-engineered laboratory instrument designed to deliver unmatched accuracy and reliability in volumetric measurements. Crafted from durable, borosilicate glass (Type I, conforming to ASTM E456 standards), this cylinder is engineered to withstand thermal shock, chemical resistance, and prolonged use in demanding laboratory environments. Its sleek, tapered design ensures minimal liquid adhesion, allowing for precise readings even at low volumes, while the etched graduations calibrated in milliliters (mL) and marked at 1 mL intervals from 0 to 500 mL provide clear, easy-to-read measurements with a total capacity of 500 mL. The threaded hex base, a distinctive feature of the TD model, offers a secure, leak-proof connection to laboratory equipment such as pipettes, funnels, or adapters, eliminating the risk of spills and ensuring seamless integration into automated or manual workflows. Whether used for titrations, dilutions, or reagent preparation, this cylinder s wide bore (approximately 30 mm) facilitates smooth pouring and minimizes splashing, while its robust construction guarantees long-term durability. Ideal for general chemistry, biology, and pharmaceutical applications, the Kimble Kimax 20024-500 combines functionality with precision, making it an indispensable tool for laboratories prioritizing accuracy and efficiency.
**Pros and Cons of buying a Kimble Kimax 20024-500 Glass Graduated Cylinder (Scale TD Hex Base)**
### **Pros:**1. **Precision and Accuracy** Glass graduated cylinders are known for their high precision in measuring liquids, making them ideal for laboratory work where exact volumes are critical.
2. **Durability** Kimble-Kimax cylinders are made from borosilicate glass, which is chemically resistant and less prone to thermal shock compared to standard soda-lime glass. This extends their lifespan, especially in applications involving temperature changes or corrosive substances.
3. **Wide Compatibility** The hex base design allows for secure placement in racks or stands, reducing the risk of tipping or spillage during use.
4. **Graduated Scale** The 500 mL capacity with clear markings provides easy readability, making it suitable for both routine and precise measurements.
5. **Autoclave-Sterilizable** If your lab requires sterilization, this cylinder can withstand autoclaving, though prolonged exposure may eventually weaken the glass.
6. **Standardized Design** Kimble-Kimax is a trusted brand in laboratory glassware, ensuring consistency in sizing and performance with other lab equipment.
7. **Low Maintenance** Unlike plastic alternatives, glass does not absorb chemicals or degrade over time, reducing the need for frequent replacements.
### **Cons:**1. **Fragility** Despite borosilicate glass being more durable than soda-lime, it is still susceptible to breakage if dropped or mishandled. This makes it less ideal for rough or high-traffic environments.
2. **Weight** Glass cylinders are heavier than plastic counterparts, which can be cumbersome for frequent handling, especially in large quantities.
3. **Cleaning Challenges** Residues like oils, proteins, or dried chemicals can adhere to glass surfaces, requiring thorough cleaning (often with detergents or ultrasonic baths) to maintain accuracy.
4. **Limited Reusability in Some Cases** While autoclave-safe, repeated sterilization cycles may eventually compromise the glass, reducing its long-term usability.
5. **Cost** High-quality borosilicate glassware is more expensive upfront than plastic or lower-grade glass alternatives.
6. **Not Ideal for High-Viscosity Liquids** Glass cylinders may struggle with liquids that cling to the sides (e.g., viscous solutions), leading to inaccurate readings unless properly wetted.
7. **Environmental Concerns** Disposing of broken glass requires careful handling, and recycling options may be limited depending on local regulations.
### **Conclusion:**The **Kimble Kimax 20024-500 glass graduated cylinder** is an excellent choice for laboratories prioritizing **precision, durability, and chemical resistance**. Its borosilicate construction makes it suitable for demanding applications, including those involving temperature fluctuations or sterilization. However, its **fragility, weight, and maintenance requirements** may pose challenges in environments where durability or ease of use is more critical than absolute precision.
If your primary needs involve **high-accuracy liquid measurements in a controlled lab setting**, this cylinder is a strong recommendation. Conversely, if **cost efficiency, portability, or resistance to rough handling** are top concerns, a **plastic or lower-cost glass alternative** (e.g., soda-lime glass) might be more practical. For most academic, research, or clinical labs, the trade-offs are justified by its performance.
**Final Recommendation:** Purchase the **Kimble Kimax 20024-500** if:- You require **high-precision measurements** in a laboratory setting.
- Your workflow involves **sterilization or exposure to corrosive chemicals**.
- You can accommodate its **weight and fragility** with proper handling and storage.
Consider alternatives (e.g., plastic cylinders or lower-grade glass) if:- **Budget constraints** are a priority.
- **Durability or ease of handling** is more important than glass s precision.
- Your applications involve **high-viscosity liquids or frequent temperature changes** where glass may be less practical.
In excellent condition, possibly new with no chips or cracks.
