Let’s Dive into Biohit mLINE Multichannel Mechanical Pipettors, Variable Volume, Biohit 725230 12-Channel
The Biohit mLINE Multichannel Mechanical Pipettor from Sartorius is a tool designed for precision and efficiency in laboratory settings, particularly when dealing with repetitive liquid handling tasks. This 12-channel pipette, model 725230, promises to streamline workflows with its variable volume range of 5-100 µL. It’s a significant investment, but the potential gains in speed and accuracy are undeniable for labs that require consistent, multi-sample processing.
My journey to the Biohit mLINE began when I was consulting for a high-throughput screening lab needing to increase efficiency without sacrificing accuracy. They were experiencing bottlenecks in their ELISA assays, where inconsistent reagent dispensing was leading to data variability. We needed a reliable solution for quickly and accurately distributing reagents across 96-well plates.
Unboxing the Biohit mLINE revealed a well-engineered instrument. The weight felt balanced, and the construction appeared robust, suggesting a focus on durability and long-term use. The multichannel head looked meticulously crafted, and the volume adjustment dial moved smoothly and precisely.
I considered the Eppendorf Research plus 12-channel and the Rainin Pipet-Lite XLS+ 12-channel before settling on the Biohit mLINE. The Biohit mLINE offered a slightly wider volume range and a reputation for ergonomic design, which was critical for reducing user fatigue during extended use. Initial impressions were positive; the pipette felt like a serious piece of equipment designed to deliver on its promise of precision and efficiency.
Real-World Testing: Putting Biohit mLINE Multichannel Mechanical Pipettors, Variable Volume, Biohit 725230 12-Channel to the Test
First Use Experience
I tested the Biohit mLINE in the high-throughput screening lab during a series of ELISA assays. The main goal was to assess its speed, accuracy, and user-friendliness in a demanding environment. The conditions were typical for a lab, with controlled temperature and humidity, but high levels of activity and potential for spills.
The Biohit mLINE performed admirably in these conditions. Dispensing reagents into 96-well plates was significantly faster than using a single-channel pipette. The ergonomic design of the Biohit mLINE became apparent quickly. I noticed a marked reduction in hand strain compared to using single-channel pipettes for similar tasks.
The only initial challenge was familiarizing myself with the volume adjustment mechanism. However, the clear display and tactile feedback made it easy to dial in the desired volume after a few practice runs. There were no immediate issues, and the initial performance was promising.
Extended Use & Reliability
After several weeks of daily use, the Biohit mLINE has proven to be a reliable workhorse. Its accuracy and precision have remained consistent. We saw a noticeable decrease in inter-assay variability as compared to the single-channel pipettes they were previously using.
The Biohit mLINE’s durability is also noteworthy. Despite being used extensively throughout the day, there are no signs of wear or tear. Cleaning the pipette is straightforward, and the autoclavable parts make it easy to maintain sterility.
Compared to previous experiences with other multichannel pipettes, the Biohit mLINE stands out for its consistent performance and ergonomic design. It has significantly improved the efficiency and reliability of the lab’s high-throughput screening process. It is a tool that has enhanced their daily work and reduced the stress on the technicians.
