I’ve spent years manually dispensing reagents for various experiments. The tediousness and potential for error led me on a quest for a reliable repeating dispenser, specifically one capable of handling volatile substances. I needed something that would improve accuracy and speed up my workflow while minimizing exposure to hazardous chemicals.
Upon unboxing, the unit felt solid and well-constructed. The glass Erlenmeyer flask had a reassuring heft. The pipet head connected smoothly to the flask with the ground joint and clamp.
I considered the BrandTech Dispensette S and the Eppendorf Repeater E3 before choosing the Tech Glass unit. The Tech Glass Repeating Dispensers TG-50360-005 Complete Units was chosen due to its compatibility with the chemicals I frequently use and its promise of high accuracy at a reasonable price point. I was hoping this would be a more cost-effective solution without sacrificing performance.
My initial reaction was cautiously optimistic. The unit looked capable, but I was eager to see if it lived up to its claims of ±2% accuracy and ease of use. The hope was that the Tech Glass Repeating Dispensers TG-50360-005 Complete Units would transform my lab work from a chore into a streamlined process.
Real-World Testing: Putting Tech Glass Repeating Dispensers TG-50360-005 Complete Units to the Test
First Use Experience
I tested the Tech Glass Repeating Dispensers TG-50360-005 Complete Units in my lab, dispensing a standard hydrochloric acid solution. The process involved repetitive titrations. I needed to consistently dispense 5mL aliquots.
The dispenser worked flawlessly under controlled laboratory conditions. Even dispensing volatile reagents like ethanol and acetone, the dispenser held its own without any leakage. The tilting mechanism to fill and dispense was simple to operate and did not require extensive training.
Initially, the tilting mechanism was a little stiff, but it loosened up after a few uses. One minor issue was that the ground joint clamp required a bit of force to secure properly. Otherwise, the first-time use was surprisingly smooth.
Extended Use & Reliability
After several weeks of consistent use, the Tech Glass Repeating Dispensers TG-50360-005 Complete Units continues to perform admirably. It has shown no significant signs of wear and tear. The glass remains clear and the dispensing mechanism continues to operate smoothly.
The dispenser requires minimal maintenance. I rinse the glass components with distilled water after each use to prevent residue build-up. The ground joint is occasionally lubricated with a small amount of silicone grease to ensure a tight seal.
In comparison to the hand-held pipettes I previously used, the Tech Glass Repeating Dispensers TG-50360-005 Complete Units is a definite upgrade. It’s significantly faster and more consistent. The dispenser has exceeded my expectations, especially given its affordability.
