This is a must-have set of products for any laboratory, whether it is for general purposes or for more complex and advanced scientific purposes.
Liquid handling is a vital element of any scientific discipline. A pipette or accessory from this category is a great way to revolutionize the way you work.With a wide variety of products, from single-channel pipettes that provide accurate microliter volumes to multichannel pipettes that enable faster and more efficient work, this category is sure to have something for every lab.
What Is Liquid Handling & Why It Matters
Liquid handling instruments are meant to facilitate the control of the movement of fluids, which may be in very small quantities, during the performance of experiments. Such instruments are used for the performance of tasks such as the transfer of solutions, preparation of reaction mixes, plating of assays, and the performance of diagnostic tests. The importance of accuracy in the handling of liquids cannot be overstated, as it not only improves the quality of results but also the reproducibility of results and the maintenance of scientific standards.
For scientists working in environments where even the smallest of changes in the volume of solutions may cause significant changes in the results of experiments, the acquisition of quality liquid handling equipment such as pipettes and other related equipment is not just important but also crucial. Whether it is the preparation of solutions for the performance of the polymerase chain reaction, the preparation of solutions for the performance of a spectrophotometric assay, or the preparation of solutions for the performance of other experiments, liquid handling equipment is crucial for the performance of experiments with speed and accuracy.
Pipettes: The Heart of Liquid Handling
The core of the liquid handling category is the pipettes, which are accurate devices used to measure and transfer specific volumes of liquids. There are diverse styles, functions, and technologies of pipettes, ranging from basic manual and air-displacement types to electronic and digital ones.
Single-Channel Pipettes
Single channel pipettes are the most popular choice among laboratories that need direct and controlled volume transfer one sample at a time. Single channel pipettes are used for a variety of applications, ranging from basic solution preparation to sensitive genetic analysis. Laboratories prefer single channel pipettes that need precision and ergonomics, especially for applications that need meticulous handling of small volumes.
Single channel pipettes usually have adjustable volume ranges, such as from fractions of a microliter to several milliliters. This makes the device versatile for different applications. Some high-precision single channel pipettes come with ergonomic designs that help prevent fatigue during repetitive operations.
Multichannel Pipettes
In the handling of multiple samples at once, such as filling wells of a microplate that contains 96 wells, a multichannel pipette greatly helps in increasing efficiency and accuracy. These are also available in different numbers of channels, such as 8 or 12 channels. This helps in the simultaneous transfer of liquids in a single operation.
Multichannel pipettes are highly beneficial in those environments where speed and standardization are of most importance. This helps in the streamlining of processes and increasing the throughput of the lab.
Electronic & Digital Pipettes
Electronic and digital pipettes combine technology and comfort. These types of pipettes use software and/or motors to provide programmable volume adjustment, repeat mode, and reduce the physical demands on the operator. Electronic pipettes can be used for repetitive work and provide customizable settings, reducing operator-induced variations in many challenging assays.
Modern pipettes, including electronic and digital types, provide a variety of features such as a digital interface, programmable volume selection, and ergonomic design to reduce operator fatigue, making them suitable for prolonged use and/or high-throughput work.
Pipette Tips & Accessories
Pipettes' performance is directly related to the quality of pipette tips and other accessory devices. There are a variety of pipette tips available, including universal, low retention, and filtered tips.
-
Universal Tips: These types of tips are compatible with a variety of pipettes, including those from other manufacturers. They are also cost-effective, making them suitable for general-purpose liquids handling.
-
Low-Retention Tips: These types of tips are designed to minimize sample adhesion, making them suitable when one needs to save samples.
-
Filtered Tips: Filtered tips ensure that there is no aerosol contamination that enters the pipette shaft, thus maintaining sterility.
Pipette tip racks and storage boxes ensure a smooth workflow, allowing users to access the appropriate tip when needed.
Pipettes' performance is also enhanced by spacers, adapters, and controllers such as pipette pumps, which ensure that users are comfortable when using the device, especially when handling large quantities of liquids, including those that are thick and volatile.
Liquid Handling Controllers & Dispensers
Although the pipettes themselves have the capabilities of handling volume measurements and transfers, the controllers and dispensers help to make the processes of aspiration as well as dispensing smooth. They make the processes more convenient.
Pipette Controllers
Controllers can be manual or battery-powered devices that can be attached to serological or volumetric pipettes. The controllers enable the controlled aspiration and dispensing of liquids using adjustable speeds and ergonomic triggers. This makes the process easier, thereby requiring less labor in the handling of liquids.
The features that make the controllers useful include the ability to adjust the aspiration speed, the ability to switch the mode of the controller, and the ergonomic grip.
Liquid Dispensers & Repeaters
Liquid dispensers and repeater pipettes are used for the rapid and repeated dispensing of the same volume of liquid over a large number of samples. These devices are particularly useful for experiments like ELISAs or for experimental protocols where the distribution of the liquid is of primary importance. They could be particularly useful in speeding up experiments that would otherwise require repeated single-pipetting steps.
Selecting the Right Pipette for Your Application
Selecting the appropriate liquid handling instruments involves several considerations, such as:
-
Volume Range: Decide whether fixed-volume or adjustable-volume pipettes are more appropriate for your protocol requirements.
-
Application Type: Employ single-channel pipettes for single sample analysis and multi-channel pipettes for plate-based analysis or high-throughput analysis.
-
Ergonomics: Choose pipettes with ergonomic features for extended pipetting applications to minimize operator fatigue.
-
Contamination Control: Utilize filtered tips and storage accessories to minimize cross-contamination, particularly for sensitive biological samples.
-
Automation Needs: For high accuracy and reduced operator interaction, electronic pipettes and controllers can provide productivity benefits.
Evaluating these considerations relative to your lab’s workflows will help optimize your liquid handling strategy for accuracy, comfort, and efficiency.
Applications Across Lab Workflows
Liquid handling equipment plays a vital role in every scientific field or laboratory process:
-
Molecular Biology & PCR Setup: Accurate microliter volume dispensing plays a critical role in nucleic acid amplification reactions.
-
Clinical Diagnostics: Reproducible pipetting ensures reliable diagnostic results, as well as compatibility with automation.
-
Cell Culture & Microbiology: Repeatable liquid handling reduces variability in media preparation or plating.
