Let’s Dive into Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510
The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 is a specialized piece of lab equipment designed for precise liquid dispensing. Manufactured by Bel-Art, this auto-zeroing burette is intended to streamline experiments requiring accurate measurements of small volumes. Its key features include a borosilicate glass burette, a high-density polyethylene bottle, and a glass stopcock.
My work in environmental sampling often demands accurate field measurements, specifically for alkalinity titrations. I needed a portable, reliable system for dispensing titrant that wouldn’t break the bank (or break in the field). The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 seemed like a promising option.
Upon unboxing, I was immediately impressed by the sturdy construction. The borosilicate glass burette felt robust, and the polyethylene bottle, while flexible, seemed durable enough for transport. The glass stopcock operated smoothly, inspiring confidence in its sealing capabilities.
I considered a digital burette from BrandTech, but the price point was significantly higher and the digital interface felt unnecessary for my basic needs. I also looked at traditional glass burettes with separate reservoirs, however, the self-contained design of the Bel-Art model was attractive for field use due to its increased portability and reduced risk of spillage. Ultimately, the combination of price, simplicity, and ruggedness led me to choose the Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510.
My first impression was a pleasant surprise. The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 appeared to be a well-built and thoughtfully designed piece of equipment ready for deployment in demanding outdoor conditions. I was excited to put it through its paces.
Real-World Testing: Putting Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 to the Test
First Use Experience
My initial testing occurred during a stream water quality assessment. I used the Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 to perform alkalinity titrations directly at the sampling site. This required transporting the filled burette in my backpack over uneven terrain.
The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 performed admirably, even in slightly windy conditions. The stopcock prevented any unwanted dripping, and the graduations on the burette were clear and easy to read. I did have to practice filling the burette a few times to get the hang of the self-zeroing mechanism.
After the first use, I noticed a minor amount of liquid residue on the outside of the stopcock. This wasn’t a leak, but it highlighted the importance of proper cleaning after each titration. Overall, the first field experience was positive.
Extended Use & Reliability
After several months of weekly use, the Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 continues to deliver reliable performance. There are no significant signs of wear and tear on either the glass burette or the polyethylene bottle. The stopcock still operates smoothly and seals effectively.
Cleaning requires only distilled water and a soft brush to remove any residue from the burette and stopcock. The polyethylene bottle can be rinsed easily as well. Compared to my previous method of using a pipette and separate flask, the Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 saves considerable time and reduces the risk of contamination.
The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 definitely outperforms my expectations for a relatively inexpensive piece of lab equipment. Its reliability and ease of use have made it an indispensable tool in my field work.
Breaking Down the Features of Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510
Specifications
The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 boasts a 10mL borosilicate glass burette for precise volume dispensing. It is mounted on a high-density polyethylene bottle, offering a flexible reservoir for the liquid. The burette features 1mL graduations, allowing accurate measurement of small volumes.
The integrated overflow system prevents overfilling by automatically returning excess liquid to the bottle during the filling process. A glass stopcock ensures a secure seal, preventing leakage and allowing for controlled dispensing. These specifications are vital for ensuring accurate and reliable titrations.
Performance & Functionality
The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 performs its job effectively, delivering accurate and consistent liquid dispensing. The self-zeroing feature is particularly useful, saving time and reducing the potential for errors. The ease of use makes it suitable for both experienced and novice users.
A minor weakness is the lack of a fine-adjustment valve for precise drop-wise dispensing, but the glass stopcock provides adequate control with practice. The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 definitely meets my expectations for a portable and reliable titration system.
Design & Ergonomics
The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 is built with durable materials, including borosilicate glass and high-density polyethylene. Its weight is balanced, making it easy to handle even when filled. The design is simple and functional, emphasizing ease of use and accuracy.
The polyethylene bottle is somewhat flexible, which can be helpful for squeezing liquid into the burette. However, this also makes it slightly less stable when placed on an uneven surface. The learning curve is minimal, even for those unfamiliar with burettes.
Durability & Maintenance
With proper care, the Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 should last for several years. The borosilicate glass burette is resistant to chemical corrosion, and the polyethylene bottle is relatively durable. Regular cleaning with distilled water and a soft brush is essential to prevent contamination and ensure smooth operation.
Repair is limited to replacing the glass stopcock, should it become damaged. All components are easily accessible for cleaning.
Accessories and Customization Options
The Bel-Art Scienceware AUTO.SELF-ZER 10ML F379150510 comes with a standard polyethylene bottle and a glass stopcock. There are no specific customization options offered by Bel-Art. However, the polyethylene bottle could potentially be replaced with a different size or material if desired.
It’s also possible to purchase replacement glass stopcocks from various suppliers. The compatibility with aftermarket accessories is limited due to the specialized nature of the product.
