Real-World Testing: Putting Tech Glass Repeating Dispensers TG-50360-055 Complete Units to the Test
First Use Experience
I first tested the Tech Glass Repeating Dispensers TG-50360-055 Complete Units in our quality control lab, specifically with a series of titrations involving a hydrochloric acid solution. The dispenser’s performance under pressure was what I cared about the most.
The unit functioned flawlessly even when dealing with this corrosive substance. Using the dispenser was surprisingly intuitive. After a few practice runs, I quickly mastered the tilting mechanism for both filling and dispensing, which made the process smooth and repeatable.
The only initial challenge I encountered was ensuring the flask was stable when tilting the pipet head. This was quickly resolved by securing the flask with a clamp.
Extended Use & Reliability
After several weeks of daily use, the Tech Glass Repeating Dispensers TG-50360-055 Complete Units have proven to be a reliable workhorse. The glass components have shown no signs of degradation, even with constant exposure to various chemicals.
Cleaning and maintenance are straightforward; a simple rinse with distilled water after each use is sufficient. Compared to the previous manual pipetting methods, the dispenser has significantly reduced the variability in our measurements, leading to more consistent results. This has saved us both time and resources.
Breaking Down the Features of Tech Glass Repeating Dispensers TG-50360-055 Complete Units
Specifications
- Volume: 50 mL. This fixed volume is ideal for repeatable dispensing.
- Flask Volume: 2000 mL. This allows for dispensing of numerous aliquots before needing to refill.
- Material: Glass. Offers excellent chemical resistance and visibility of contents.
- Joint: ST 24/40. The standard taper joint ensures compatibility and a secure seal.
- Accuracy: ±2%. A key spec, making this suitable for precise dispensing applications.
These specifications are critical because they directly impact the precision and reliability of our lab work. The glass construction ensures chemical compatibility, while the tight seal of the ST joint prevents leaks and maintains the purity of the reagents. The ±2% accuracy is essential for consistent and dependable test results.
Performance & Functionality
The Tech Glass Repeating Dispensers TG-50360-055 Complete Units excels in delivering repeatable and accurate dispensing of liquids. The tilting mechanism allows for rapid and efficient transfers.
The primary strength is its consistent dispensing volume, significantly reducing human error. The only area for improvement is the need for a more robust base for the flask, as the existing Erlenmeyer flask can be somewhat unstable during tilting. It has exceeded our expectations.
Design & Ergonomics
The Tech Glass Repeating Dispensers TG-50360-055 Complete Units features a straightforward and functional design. The glass components offer excellent visibility.
The unit feels well-balanced and easy to handle, although a larger or more stable base for the flask would improve ergonomics. There is a small learning curve. You must get familiarized with the tilting motion.
Durability & Maintenance
With proper care, the Tech Glass Repeating Dispensers TG-50360-055 Complete Units should last for years. The glass components are resistant to most chemicals commonly found in a lab setting.
Maintenance is minimal, requiring only cleaning after use. Replacement pipet heads are available if needed.
Accessories and Customization Options
The complete unit includes the pipet head, Erlenmeyer flask with an ST 24/40 ground joint, and a poly joint clamp. No additional accessories are included in the kit, but the pipet heads can be ordered separately with an ST 24/40 inner joint for easy interchanging of the dispensers.
While there are no readily available “customization” options, the standard ST 24/40 joint opens the door to integrating the dispenser with other compatible glassware setups. The system is a great standardized size.
