Review VWR Lot Of Vwr/kimax 89000-384/27060-250 500/250ml Heavy Walled Filter Flasks

The **VWR 89000-384 (Kimax 89000-384/27060-250) 500/250 mL Walled Filter Flask** is a high-quality, precision-engineered laboratory glassware essential for a wide range of filtration and distillation applications in academic, industrial, and pharmaceutical settings. Crafted from durable **borosilicate glass (Type 1, Kimble Kimax)**, this flask is designed to withstand extreme temperature fluctuations, chemical resistance, and rigorous use, ensuring long-term reliability and accuracy in experiments. The **walled design** featuring a distinctive, reinforced side wall enhances structural integrity during filtration processes, reducing the risk of cracking or deformation under vacuum or pressure conditions. With a **500 mL capacity** and a **250 mL graduated scale**, this flask provides versatility for both small-scale and medium-scale procedures, allowing researchers to measure and transfer liquids with precision. The **standard taper 24/40 joint** ensures a secure, leak-proof connection to compatible filtration funnels, condensers, or other laboratory glassware, while the **flat-bottom design** promotes stability on heated surfaces or during centrifugation. Ideal for use with **B chner funnels, Hirsch funnels, or vacuum filtration setups**, this flask is engineered to facilitate efficient solid-liquid separation, making it a cornerstone in processes like recrystallization, solvent recovery, and sample preparation. Its **clear, uncoated borosilicate construction** allows for easy visualization of reactions and filtration progress, while the **smooth, polished finish** minimizes residue buildup and simplifies cleaning. Whether used in routine laboratory workflows or specialized research applications, this flask combines durability, functionality, and precision to meet the demands of modern analytical and synthetic chemistry.

### **Pros and Cons of Buying VWR 89000-384 Walled Filter Flasks (and Alternatives)**

1. **Durability and Quality** VWR (now part of Thermo Fisher Scientific) is a reputable supplier known for producing high-quality laboratory glassware. The borosilicate glass used in these flasks is resistant to thermal shock and chemical corrosion, making them suitable for a wide range of applications, including filtration, extraction, and storage of liquids.

2. **Precision and Consistency** The flasks are manufactured to tight tolerances, ensuring accurate volume measurements. The walled design (with a flat base and straight sides) provides better stability during filtration compared to standard Erlenmeyer flasks.

3. **Compatibility with Standard Laboratory Equipment** These flasks are designed to fit standard laboratory setups, including filter funnels, adapters, and vacuum systems. The 384-mL capacity is versatile for medium-scale experiments.

4. **Sterilization and Reusability** Borosilicate glass can be autoclaved or baked for sterilization, making these flasks reusable over many experiments. This reduces long-term costs compared to disposable alternatives.

5. **Chemical Resistance** The glass is resistant to most acids, bases, and organic solvents, making it suitable for a broad range of chemical and biological applications.

6. **Brand Reliability** VWR is a trusted name in laboratory supply, offering warranties and customer support. The flasks are backed by quality assurance standards, reducing the risk of defects.

7. **Alternative Options (Kimax, 27060-250, etc.)**

- **Kimax (Corning brand)**: Another high-quality borosilicate glass option with similar durability and chemical resistance. Often slightly more affordable than VWR but equally reliable.

- **27060-250 (VWR s lower-cost alternative)**: A 250-mL version of the same design, useful for smaller-scale work. The 500-mL version (89000-500) offers more capacity for larger filtrations.

- **Cost-Effective Bulk Purchases**: Buying in bulk (e.g., sets of multiple flasks) can reduce per-unit costs significantly.

---

1. **Cost** High-quality borosilicate glassware is more expensive upfront than disposable or lower-grade alternatives. A single 384-mL flask may cost between $15 $30, depending on the supplier and quantity purchased.

2. **Breakage Risk** While durable, glassware is still fragile. Improper handling, thermal shock (e.g., sudden temperature changes), or rough treatment can lead to cracks or breakage, especially during filtration under vacuum.

3. **Maintenance Requirements**

- **Cleaning**: Residues (e.g., proteins, oils, or precipitates) can be difficult to remove, requiring thorough washing with detergents, sonication, or acid rinses.

- **Storage**: Must be stored upright or in a rack to prevent chips or scratches on the base or sides.

- **Replacement Costs**: If broken, replacements add up over time.

4. **Weight and Portability** Glass is heavy, making bulk transport or frequent movement cumbersome. This can be a drawback in fieldwork or mobile laboratories.

5. **Alternative Disposable Options**

- **Disposable Filter Flasks (e.g., polypropylene)**: Cheaper for single-use applications, eliminating breakage risks and cleaning time. However, they lack the chemical resistance and precision of glass.

- **Plastic or Silicone Alternatives**: Useful for non-corrosive applications but may degrade over time or leach contaminants.

6. **Limited Color Options** Most borosilicate flasks are clear or amber (for light-sensitive samples), but specialized colors (e.g., brown for UV protection) may require additional cost.

7. **Supplier Dependence** Relying on a single supplier (e.g., VWR) may limit flexibility if pricing changes or stock is unavailable. Comparing prices across vendors (e.g., Fisher Scientific, Sigma-Aldrich, or local suppliers) can help secure better deals.

### **Conclusion and Recommendation**

The **VWR 89000-384 walled filter flasks** (and their alternatives like Kimax or VWR s 27060-250 series) are **ideal for laboratories requiring durability, precision, and chemical resistance** in medium-scale filtration or storage tasks. They are particularly well-suited for:

- **Chemical synthesis** (where solvent resistance is critical).

- **Biological applications** (e.g., cell culture filtrations, protein purification).

- **Long-term use** in research or teaching settings where reusability outweighs the initial cost.

**However**, if budget is a constraint or the application involves **frequent single-use scenarios**, disposable alternatives may be more practical despite their lower chemical resistance. For **small-scale work**, the 250-mL or 500-mL versions offer flexibility without overinvesting.

- You prioritize **durability, chemical resistance, and precision** for repeated use.

- Your budget allows for the upfront cost, and you can justify the long-term savings from reusability.

- You work with **corrosive reagents, high temperatures, or require autoclavable equipment**.

- You perform **one-time or low-frequency filtrations**.

- **Cost per use** is more critical than glass quality (e.g., in teaching labs or pilot studies).

- **Breakage risk** is a concern (e.g., in high-traffic or student-run labs).

**Cost-Saving Tip:** Purchase in bulk (e.g., sets of 10 20) to reduce per-unit costs. Compare prices across suppliers (VWR, Fisher Scientific, or regional lab supply stores) and check for discounts or promotions. If possible, opt for the **27060-250 series** for smaller volumes or the **500-mL version** for larger-scale needs. Always verify compatibility with your specific filtration setup (e.g., vacuum adapters, filter paper sizes).
