Real-World Testing: Putting Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom to the Test
First Use Experience
I first tested the Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom in my small, temperature-controlled lab. The first test involved drying a batch of synthesized nanoparticles, a process highly sensitive to moisture. Setting up the vacuum was straightforward, and the unit quickly reached the desired pressure.
Under standard lab conditions, around 22°C and 50% humidity, the desiccator performed admirably. It was easy to monitor the samples through the clear top. After the first 24 hours under vacuum, I observed no significant increase in pressure, suggesting a good seal.
Extended Use & Reliability
After several weeks of continuous use, the Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom has proven to be a reliable workhorse. It has consistently maintained a stable vacuum, crucial for long-term sample storage. There are no signs of significant wear and tear.
Cleaning is simple; a quick wipe with a damp cloth is usually sufficient. Compared to my previous experience with a similar desiccator from another brand, the Bel-Art model retains the vacuum significantly better over extended periods. The Bel-Art easily outperforms its predecessor, providing greater peace of mind when storing sensitive materials.
Breaking Down the Features of Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom
Specifications
The Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom boasts several key specifications. These features directly influence its performance and suitability for specific applications.
- I.D.: 149 mm: The inner diameter dictates the maximum size of samples or containers that can be accommodated. This is sufficient for most standard petri dishes or small sample vials.
- Flange O.D.: 171 mm: The outer diameter of the flange provides stability and a secure sealing surface. This ensures a tight seal when the top and bottom sections are joined.
- Overall Ht.: 206 mm: The overall height ensures a compact footprint, crucial for saving space on crowded lab benches. This height is suitable for stacking multiple units if needed.
- Takes Plate Dia.: 140 mm: This measurement indicates the maximum diameter of a desiccant plate that can be used inside the desiccator. Using appropriately sized desiccant maximizes moisture absorption.
- Holds Vacuum of 740mm of Hg (29″) for 24 hrs: This is the most crucial specification, indicating the desiccator’s ability to maintain a vacuum. This level of vacuum is sufficient for most desiccation purposes, ensuring samples remain dry and stable.
- The material composition, featuring an unbreakable, transparent polycarbonate upper section and a polypropylene or polycarbonate lower section. This provides both visibility and durability.
Performance & Functionality
The Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom excels in maintaining a stable vacuum. Its unique vacuum retention valve, operated by slowly turning a polyethylene plug, allows for precise control of air intake. The seal, enhanced by a neoprene O-ring, remains unaffected by cold temperatures (0°C), expanding its usability in various environments.
However, the vacuum valve, while effective, requires careful handling to avoid over-tightening the polyethylene plug. Overtightening may damage the seal over time. The desiccator meets expectations for short-term and medium-term desiccation needs, offering reliable performance in controlled laboratory conditions.
Design & Ergonomics
The Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom features a functional and practical design. The clear polycarbonate top provides excellent visibility of the contents without needing to open the desiccator. The polypropylene or polycarbonate bottom is robust and resistant to common lab chemicals.
The lightweight construction makes it easy to move and handle. The simple design requires no specialized training or expertise to operate.
Durability & Maintenance
The materials used in the Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom are resistant to most common lab chemicals, contributing to its longevity. Routine maintenance involves only cleaning with a mild detergent and ensuring the O-ring remains lubricated. The durable construction suggests it will last for several years under typical lab conditions.
Replacements for the O-ring and vacuum valve components are available from Bel-Art. This allows for easy repairs, extending the lifespan of the unit.
Accessories and Customization Options
The Bel-Art Space Saver Vacuum Desiccators, SCIENCEWARE 420120000 Clear Polycarbonate Bottom itself comes as a standalone unit. Desiccant plates or desiccant beads, which are crucial for the desiccation process, must be purchased separately. The unit is compatible with any standard 1/4″ I.D. vacuum tubing for connection to a vacuum pump.
While not strictly customization, different desiccant types (e.g., silica gel, molecular sieves) can be selected based on the specific requirements of the samples being stored. This provides flexibility in tailoring the desiccation environment.
