The VWR Pipet Filler, Synthetic Rubber K200-VWR Vwr Pipet Filler Red 2-50ML: A Review After Real Use
The VWR Pipet Filler, Synthetic Rubber K200-VWR Vwr Pipet Filler Red 2-50ML is a seemingly simple piece of lab equipment, but for anyone who’s spent countless hours manually pipetting, the allure of a reliable and easy-to-use filler is strong. Manufactured by VWR, this red synthetic rubber filler promises effortless liquid aspiration and dispensing for volumes ranging from 2-50mL. For me, the promise of reduced hand strain and increased accuracy in my own experimental testing spurred me toward finally giving this device a try.
My own experiences in my early research years were marked by repetitive strain injuries sustained while manually drawing reagents. I was searching for a solution that would let me do my work efficiently, without risking my hands and wrists, while also keeping in mind accuracy of aspiration. The VWR Pipet Filler seemed to fit the bill, especially with its reported non-skid properties and easy connection to pipettes.
Upon unboxing, the bright red color was immediately striking. The rubber felt pliable and appeared well-constructed. My initial impression was that it felt solid, but not overly heavy, and was clearly designed for repetitive use, without being too clunky.
I had previously used the classic, green rubber bulb pipet fillers common in teaching labs, and a more sophisticated electronic pipet aid. Compared to the rubber bulb, the VWR Pipet Filler felt significantly more robust and offered finer control. I chose it over the electronic pipet aid because of its simplicity and lower cost, as well as not requiring any electrical components.
My first impression was cautiously optimistic. It appeared like a potentially great solution. My concerns were centered around whether the synthetic rubber would stand up to repeated exposure to solvents and reagents, and how comfortable it would be to use for extended periods.
Real-World Testing: Putting VWR Pipet Filler, Synthetic Rubber K200-VWR Vwr Pipet Filler Red 2-50ML to the Test
First Use Experience
I tested the VWR Pipet Filler in my research lab while preparing serial dilutions of stock solutions for antimicrobial susceptibility testing. The lab environment involves constant use of aqueous and organic solvents, as well as exposure to fluctuating temperatures. I aimed to test how well the VWR Pipet Filler handled these varied conditions.
The VWR Pipet Filler performed admirably even with varying conditions. Even with damp hands or while wearing gloves, it remained easy to grip. The non-skid filler joint was a huge help in allowing for smooth and precise liquid aspiration, even in wet environments.
The initial use was intuitive and easy. I was quickly able to control the rate of liquid aspiration and dispensing, far better than I could with the basic bulb fillers. There was no need for much of a learning curve.
My only initial concern was that the rubber smell was noticeable upon first unpacking. But this quickly dissipated after a few uses.
Extended Use & Reliability
After several months of regular use, the VWR Pipet Filler has become an indispensable tool in my lab. It has held up very well to repeated use and exposure to common lab solvents like ethanol and isopropanol. The synthetic rubber has shown no signs of cracking or degradation.
Despite heavy daily use, there are no significant signs of wear and tear. The red color has remained vibrant. The non-skid filler joint still performs as reliably as it did on day one.
Cleaning and maintenance have been a breeze. A quick wipe down with a damp cloth is usually all that’s needed. I occasionally use a mild detergent to remove any stubborn residue.
Compared to the frustrating inconsistency of bulb fillers and the electrical dependency of pipet aids, the VWR Pipet Filler has exceeded my expectations. It offers a fantastic balance of control, reliability, and ease of use.
