Real-World Testing: Putting Greiner Bio-One Disposable Serological Pipets, Polystyrene, Sterile, Greiner Bio-One 768180 Packaged In Individual Paper/Plastic Wrappers, Case of 100 to the Test
First Use Experience
I primarily tested the Greiner Bio-One Disposable Serological Pipets, Polystyrene, Sterile, Greiner Bio-One 768180 Packaged In Individual Paper/Plastic Wrappers, Case of 100 in a research laboratory setting, crucial for accurately measuring enzyme dilutions and cell culture media. The lab environment demanded absolute cleanliness, where even the smallest contamination could ruin weeks of work. The individual paper/plastic wrappers made sterile handling extremely easy; simply peel back the wrapper and insert the pipet into the pipette aid.
The pipets performed admirably even in conditions that demanded quick transfers and multiple dilutions. The clear polystyrene and sharply printed graduations made it easy to read the liquid levels. There were no initial surprises or malfunctions, only smooth and accurate liquid transfers.
Extended Use & Reliability
After several months of regular use, the Greiner Bio-One pipets have proven to be incredibly reliable and durable, considering their disposable nature. I haven’t observed any batch-to-batch variability, ensuring consistent accuracy throughout the case. Maintenance is essentially non-existent as they are disposable.
Compared to reusable glass pipettes that require meticulous cleaning and autoclaving, these Greiner Bio-One pipets have significantly streamlined our workflow. They outperform expectations in terms of consistency and convenience, reducing the overall time and effort involved in liquid handling.
Breaking Down the Features of Greiner Bio-One Disposable Serological Pipets, Polystyrene, Sterile, Greiner Bio-One 768180 Packaged In Individual Paper/Plastic Wrappers, Case of 100
