So, you want to explore pipettes? From Techniques to Trade-Ins: The Guide to Choosing the Right Pipette for Your Application

Laboratory work is pertinent to an exceptionally broad scope of principles and professions. But for all the different research fields, there is a unifying factor – most rely on pipettes to safely and accurately transfer liquid samples and conduct repeatable experiments. Most – if not all – basic laboratory guides feature sections about pipettes and pipetting techniques. Indeed, pipetting is one of the most common tasks performed in lab settings and one of the most important. It is important to remember that pipetting is not a one-size-fits-all process. Everything from liquids to workflow can directly influence the pipettes, accessories and pipetting techniques that should be used. Because pipetting occurs so frequently in lab settings, it stands to reason a user would want to ensure proper equipment and techniques are always used.  

But what constitutes proper equipment and technique?  

There are several factors to consider regarding pipettes and pipetting but making these choices does not have to be a daunting task. Sartorius offers an all-inclusive buyers guide for selecting pipettes and pipetting accessories and a robust library of resources, so there is never a missed step when it comes to technique, maintenance, etc.  

Decisions, Decisions: Choosing the Perfect Pipette

Deciding your laboratory requires pipettes is the easy part. The breakdown of needs and variables will ultimately determine which pipette and accessory choices will make the most sense.

Quick Tip: A good rule of thumb is to remember the highest accuracy levels are achieved by choosing the smallest volume pipettes capable of handling your volumes. Pipettes are most accurate at nominal volume.

Before you purchase your next pipette, consider the following:

  1. For which applications will the pipettes commonly be used?
  2. What type of work is involved (Quality Control, pharmaceutical safety, life sciences)?
  3. What is the typical workflow?
  4. What are the sample materials?

Consider These Top Ten Features When Choosing Your Next Pipette:

  1. Ergonomics and Handling Comfort - The action of pipetting can cause repetitive strain injuries (RSI), which can not only cause pain and discomfort but can also impact the precision and accuracy of results. Consider things like tip ejection force and grip design when choosing a unit. Also, check the weight of the pipette. Lightweight is essential in long pipetting sessions to prevent muscle strain. 
  2. Air vs. Positive Displacement - There are two types of piston-operated pipettes: air displacement and positive displacement. Most lab pipetting is done using air displacement pipettes, which have air columns between the piston and the liquid. With positive displacement pipettes, the piston is in direct contact with the liquid. These are typically used for demanding samples involving viscous, volatile or radioactive liquids. 
  3. Accuracy, Precision Requirements - Accuracy means delivered volume = set volume; precision expresses proximity of multiple pipetting results. These are two of the most critical aspects when choosing a pipette. 
  4. Single vs. Multichannel Pipette - Does your lab work involve pipetting to and from tubes and vessels of various sizes, with no degree of uniformity? Do you engage in large-volume pipetting (1.2 – 10 mL)? For cases such as these, single-channel pipettes are the optimal choice. When working with 96 or 384-well plates, in situations when sample numbers are large, multichannel pipettes are a better option. 
  5. Fixed vs. Variable Volume - Variable volume pipettes are the industry standard, as it makes sense to use equipment that can be adjusted to various needs and measurements. There are, however, times when fixed volume pipettes have advantages, particularly when working with consistent volumes like in clinical testing or patient samples. Fixed volume pipettes remove a source of error, as there is no chance of selecting an improper volume.
  6. Autoclaving - Check whether the pipette is fully autoclavable – meaning it can be autoclaved as is, or whether it requires disassembly as some parts, like electronics, might not tolerate autoclaving. Autoclaving is the most efficient way to decontaminate a pipette. 
  7. Volume Lock - Make sure the pipette has a proper volume lock to avoid accidental volume changes. 
  8. Visible Display - An easy-to-read volume display makes for efficient and reliable working conditions. Check that the volume is displayed in numbers, down to the last decimal.
  9. Light Operation - Avoid unnecessary strain by making sure the pipette plunger is light to press at both maximum and minimum volumes. Also remember to check for light tip ejection as it is the most force demanding action during pipetting.
  10. Easy Maintenance - Check that the pipette is easy to disassemble without tools and has only a few parts to clean.

Exploring Pipetting Needs Through Applications

Understanding the specific needs of your application can help you select the right pipette and improve your results. There is a strong correlation between lab applications and the type of pipetting equipment to get the job done in the best possible way. Everything from sample medium to sterility requirements plays a role in the types of pipettes and accessories used. Knowing which pipettes and accessories most effectively mesh with various applications can keep pipetting tasks safe, accurate and repeatable - regardless of your field. 

Four common applications that involve pipetting include:

  1. Cell-based Assays - Cells are typically sensitive and require careful handling in laboratory settings. To ensure optimal success in cell-based experiments, it is recommended that electronic pipettes be used with filter tips, using good pipetting techniques that eliminate foaming and bubble formation during cell seeding. 
  2. Cell Culture Work - A common hazard in cell culture work is contamination. The invasion of mold, bacteria and mycoplasma (to name a few) is detrimental to the sample and poses a risk to the entire laboratory. Additionally, cells should only be away from incubators for a minimal amount of time to preserve their integrity. These conditions call for multichannel pipettes (to expedite workflow) that are equipped with filter tips and fully autoclavable (to prevent contamination). (Learn more about the best practices for pipetting 3D cell culture hydrogels.)
  3. Microbiology - When studying bacteria, viruses, algae and other micro-organisms, contamination prevention is paramount. Mixing populations or introducing unwanted strains should be avoided. Best practices dictate aseptic working methods using sterilized lab equipment. Fully autoclavable pipettes with pre-sterilized tips and pipette controllers – fitted with sterile filters – are the optimal choice to achieve this ideal working environment.
  4. Chemicals - In chemical industry labs, it can be tricky to continuously achieve reliable results due to the aggressive nature of chemicals. Pipettes engineered for reliability (such as Proline® Plus) and paired with chemical-resistant pipette tips can make the job much easier. Chemical-resistant bottle top dispensers can also reduce spillage risks. (Explore on-demand webinar on best practices for pipetting in chemical labs.)

Working Smarter: Pipette Accessories and Consumables

Top Five Pipette Tips:

  1. Standard Pipette Tips – As indicated, standard tips are the most used in laboratories and are suitable for most applications. 
  2. Filtered Pipette Tips – If the prevention of cross-contamination is a critical element of your workflow – or if handling dangerous liquids is common – filtered tips are recommended for maximum safety.
  3. Low binding or Low Retention Pipette Tips – Low retention pipette tips are the most useful when transferring viscous and sticky liquids. (Learn more about performance comparison of low retention pipette tips from various manufacturers)
  4. Extended Length Pipette Tips – Extended length tips allow users to reach samples without putting the shaft of the pipette into the vessel from which the liquid is being retrieved. 
  5. Wide Bore Pipette Tips – These tips are a great choice for handling samples with great care (i.e., cell or DNA-handling, or samples containing particulates). 

Important Pipette Tip Selection Criteria

Additionally, when selecting pipette tips, the user must evaluate pipette tip compatibility with the pipette, the quality and purity of the tips, and how good the tip packaging is. 

Pipette Compatibility

  • The tip must be compatible with the pipette. The performance you are able to get depends on the system, not the tip or pipette alone. 
  • In most cases, the tips from the pipette manufacturer offer the best fit. 

Tip Quality

  • The tip must be in the correct size and shape.
  • Any deviation, like bent tips, may cause inaccuracy and imprecision in the results.


  • In trays (or boxes), tips are ready to be packed, without the need for the user to touch the tips with hands.
  • When packaged in bulk, the tips usually need to be picked by hand and refilled into a box.

Tip Purity

  • The manufacturing process is critical to the tip purity.
  • Tip purity is typically tested per production lot and a lot-specific certificate is written after confirming purity.

Tip Certification

  • Proof of manufacturing or purity processes and quality.

Keep it Clean: Tips for Effective Pipette Cleaning

Pipettes are used to transfer a multitude of samples and media, including liquids that can be viscous, hazardous, or potential contaminants. Thorough cleaning is a must to keep equipment in working order and maintain sample integrity. 

It is important to always follow the manufacturer's recommendations when it comes to cleaning pipettes and pipette equipment. A good tip to keep in mind when undertaking the following practices: 

  • Daily cleaning - For pipettes employed in day-to-day use, daily cleaning is paramount before hanging up the safety goggles for the night. With Sartorius pipettes, it is recommended that tip cone filters be changed, if applicable, followed by a thorough outer body cleaning with 70% ethanol. During this procedure, it is useful to check for cracks, defects or anything else that might prove detrimental to equipment function.
  • Full cleaning – Follow manufacturer instructions for disassembling your pipette. It is very important to know the chemical compatibilities of your equipment before using cleaning and/or decontamination solutions (to include pure water, detergents, nuclease removal agent, radioactivity cleaning agent and sodium hypochlorite). After a thorough cleaning, you may wish to autoclave your instrument. Autoclaving is an efficient way to sterilize pipettes from biological contaminants like viruses and bacteria. Follow manufacturer instructions for autoclaving, and check which parts are autoclavable (some pipettes are fully autoclavable, but others are not). Always use correct settings. Also, after disassembling a pipette it is always recommended to check the performance.

Keep it Maintained: Pipette Maintenance Influences Equipment Performance
