Let’s Dive into VWR Signature Single-Channel Pipettors, Fixed Volume P3820-5VWR
The VWR Signature Single-Channel Pipettors, Fixed Volume P3820-5VWR is a vital tool for any lab needing precise and repeatable liquid handling. Designed by VWR, this fixed-volume pipette promises accuracy and ease of use in a compact, autoclavable package. It is ideal for applications where consistency and reliability are paramount.
My work in a high-throughput screening lab demanded accurate and fast pipetting of small volumes. We needed a pipette that could consistently dispense 5 µL, minimizing errors and maximizing throughput. The VWR Signature Single-Channel Pipettors, Fixed Volume P3820-5VWR seemed like it would fit the bill.
Unboxing the VWR pipette, the first thing I noticed was its lightweight and ergonomic design. The pipette felt well-balanced in my hand, and the slender shaft gave me confidence that it would fit into various tube sizes. The build quality seemed solid, and the tip ejector moved smoothly.
Compared to older pipettes we had from Gilson and Eppendorf, the VWR model seemed simpler in design. While those models offered adjustable volumes, the fixed volume of this VWR pipette promised greater consistency for our specific application. Initial impressions were good, with a sense of anticipation that this tool could significantly improve our workflow.
Real-World Testing: Putting VWR Signature Single-Channel Pipettors, Fixed Volume P3820-5VWR to the Test
First Use Experience
My first test involved dispensing a colored dye into microplates for a visual check of accuracy. Using the recommended 200 µL tips, the pipette filled and dispensed the 5 µL volume smoothly and consistently. I tested the pipette by dispensing into multiple microplates for high-throughput drug design.
The lab environment was generally dry and at room temperature. However, when working under the laminar flow hood, the cool air didn’t seem to affect the pipette’s performance. The VWR Signature Single-Channel Pipettors, Fixed Volume P3820-5VWR felt comfortable even after prolonged use, reducing hand fatigue.
No major issues arose during the first use, although I did need to adjust the tip ejector slightly to ensure proper tip release. The smooth plunger action and consistent dispensing were immediately noticeable improvements over some of our older equipment.
Extended Use & Reliability
After a month of daily use, the VWR Signature Single-Channel Pipettors, Fixed Volume P3820-5VWR continued to perform reliably. Regular use of this product involved high-throughput screening of potential drug candidates. There were no signs of significant wear and tear.
We cleaned the pipette regularly with isopropyl alcohol after each use, following the manufacturer’s recommendations. The pipette maintained its accuracy and precision even after repeated autoclaving, which is crucial for maintaining sterility in our lab. Compared to a previous no-name brand fixed-volume pipette, the VWR model maintained its performance over time, showing no signs of volume drift or inconsistencies.
