Let’s Dive into BrandTech BRAND Transferpettor Single-Channel Positive Displacement Pipettors, Variable Volume, BrandTech 2702912
The BrandTech BRAND Transferpettor Single-Channel Positive Displacement Pipettors, Variable Volume, BrandTech 2702912 offers a unique solution for handling challenging liquids in laboratory settings. Specifically designed for viscous, volatile, and foaming substances, this pipettor promises accuracy and reliability where traditional air displacement methods fall short. The BrandTech Transferpettor intrigued me with its claim of eliminating cross-contamination and the need for calibration.
My work often involves transferring glycerol solutions and various essential oils. These are substances that wreak havoc on standard pipettes. Air displacement pipettes consistently deliver inconsistent volumes due to the liquid’s properties. I hoped the BrandTech Transferpettor would solve this problem and bring precision to my often frustrating tasks.
Upon unboxing, the Transferpettor felt robust and well-made. The PVC construction felt durable, while the variable volume adjustment mechanism turned smoothly. The overall design was clean and functional, giving the impression of a tool built for purpose. I immediately noted its weight, heavier than standard pipettes, likely due to its positive displacement mechanism.
I considered other options like positive displacement pipettes from Eppendorf and Hamilton. However, the BrandTech Transferpettor’s variable volume range of 2-10 mL and its specific design for volatile liquids swayed my decision. The lower price point compared to some competitors was also a factor. My initial impression was one of cautious optimism; I was eager to see if it lived up to its claims.
Real-World Testing: Putting BrandTech BRAND Transferpettor Single-Channel Positive Displacement Pipettors, Variable Volume, BrandTech 2702912 to the Test
First Use Experience
My first test involved transferring a highly viscous silicone oil. I used it within a controlled lab setting. The traditional air displacement pipette struggled mightily, delivering inconsistent volumes and exhibiting significant “drool” after dispensing. The BrandTech Transferpettor, however, performed admirably.
It aspirated and dispensed the viscous oil smoothly and accurately. There was no noticeable dripping or residual liquid clinging to the tip. The positive displacement mechanism provided a noticeable improvement in control and precision.
The only adjustment I needed was adapting to the increased force required to depress the plunger. This is due to the direct displacement of the liquid. Overall, my first use was a resounding success.
Extended Use & Reliability
After several weeks of consistent use, the BrandTech Transferpettor continues to impress. It maintains its accuracy and reliability across a range of liquids, from volatile solvents like acetone to thick resins. The PVC construction shows no signs of degradation or chemical attack, even with frequent exposure to harsh chemicals. Cleaning the exterior is simple.
Maintenance primarily involves replacing the disposable tips. So far, no other maintenance has been needed. Compared to my previous experiences with air displacement pipettes struggling with similar tasks, the BrandTech Transferpettor is a clear winner. It provides consistent, reliable performance and has significantly reduced errors in my experiments.

The specifications highlight the BrandTech Transferpettor’s suitability for handling volumes in the 2-10 mL range. The fine 10 µL increments allow for precise dispensing. Its design specifically for viscous and volatile liquids is crucial for reliable performance with those materials.
Performance & Functionality
The BrandTech BRAND Transferpettor Single-Channel Positive Displacement Pipettors, Variable Volume, BrandTech 2702912 excels in its primary function: accurately and reliably transferring difficult liquids. Its positive displacement mechanism ensures consistent volumes, regardless of the liquid’s viscosity, volatility, or tendency to foam. This is a significant advantage over air displacement pipettes.
The one-way positive displacement with one-way transfer tips design is also a key strength, minimizing cross-contamination. The ability to set up for continuous flow or trickle adds versatility to its functionality. However, the lack of sterilization options (other than autoclaving the tip) could be a limitation in some applications.
Overall, the Transferpettor meets and often exceeds expectations for handling challenging liquids.
Design & Ergonomics
The BrandTech Transferpettor’s PVC construction feels durable and chemically resistant. However, the instrument’s weight can become noticeable during extended use. The variable volume adjustment is smooth and easy to use.
The ergonomics are generally good. However, the increased force required to depress the plunger can cause fatigue during repetitive pipetting. There is a slight learning curve associated with adapting to the positive displacement mechanism.
Durability & Maintenance
The BrandTech Transferpettor appears to be built for long-term use. The PVC construction is resistant to chemical degradation and mechanical wear. The instrument is easy to clean and maintain.
The primary maintenance requirement is replacing the disposable tips, which are readily available. With proper care, this pipettor should provide years of reliable service.
Accessories and Customization Options
The BrandTech BRAND Transferpettor Single-Channel Positive Displacement Pipettors, Variable Volume, BrandTech 2702912 comes with limited accessories beyond the disposable tips. There are no specified customization options for the body of the pipettor itself. However, the compatibility with standard pipette tips from BrandTech and other manufacturers provides some flexibility.
