Introduction

Introduction

Not every laboratory workflow requires filter pipette tips.

For routine liquid handling, a high-quality universal pipette tip may be entirely appropriate. For workflows where aerosol contamination or sample carryover is a significant concern, filter tips can provide an additional barrier between the sample and the pipette.

So how do you know which one your lab needs?

The answer depends on what you’re pipetting, how sensitive your workflow is to contamination, and what level of protection your application requires.

In this guide, we’ll explain the difference between universal and filter pipette tips, when each type makes sense, and what to consider before choosing one for your lab.

What Is the Difference Between Universal and Filter Pipette Tips?

What Is the Difference Between Universal and Filter Pipette Tips?

The main difference is simple:

Universal pipette tips do not contain an aerosol barrier, while filter pipette tips contain a filter designed to reduce the movement of aerosols and contaminants into the pipette.

Both types can be available in different volumes, materials, sterility levels, and compatibility configurations.

The important distinction is the level of contamination protection required by the workflow.

During pipetting, aerosols and small droplets can potentially travel into the pipette cone. If contaminants enter the pipette, they can potentially be carried into subsequent samples. Filter tips are designed to help reduce this type of contamination.

Universal Pipette Tips: What Are They?

Universal Pipette Tips: What Are They?

Universal pipette tips are designed to fit a range of commonly used pipettes rather than being manufactured exclusively for one pipette model or brand.

They are widely used for routine laboratory liquid handling.

Depending on the product, universal tips may be available as:

• Standard tips
• Low-retention tips
• Sterile tips
• Non-sterile tips
• Racked tips
• Bulk tips
• Automation-compatible tips

Sequence BioTech offers a range of laboratory consumables and pipette tips, including Sorenson One-Touch, LTS-compatible, Vertex, and MultiMax options.

When are universal pipette tips appropriate?

When are universal pipette tips appropriate?

Universal tips can be suitable for workflows where aerosol contamination is not a primary concern and where the tip’s fit, quality, and cleanliness specifications meet the requirements of the application.

Examples may include certain:

• Routine liquid transfers
• Buffer preparation
• Reagent handling
• General laboratory workflows
• Non-sensitive liquid handling applications

The key is not simply whether a tip is labeled “universal.” The tip still needs to provide a reliable fit and meet the requirements of the specific pipette and application.

Filter Pipette Tips: What Are They?

Filter Pipette Tips: What Are They?

Filter pipette tips contain a porous filter positioned inside the tip.

The filter acts as a barrier intended to reduce the movement of aerosols and contaminants into the pipette cone.

Different filter-tip designs are available, so “filter tip” does not necessarily mean every product provides exactly the same level of protection.

The filter material, design, and manufacturing quality can all matter.

Sequence BioTech currently offers sterile filter tip options across several consumable lines, including Sorenson One-Touch, Vertex, Chanshow, and MultiMax.

When Should You Use Filter Pipette Tips?

When Should You Use Filter Pipette Tips?

Filter tips are particularly relevant when your workflow has a higher risk of aerosol contamination or when cross-contamination could compromise results.

They are commonly considered for applications such as:

PCR and Molecular Biology

PCR workflows are particularly sensitive to contamination.

Thermo Fisher Scientific recommends aerosol-resistant filtered pipette tips as part of contamination-control practices for PCR workflows.

Sequence BioTech also offers [PCR laboratory consumables] as part of its broader laboratory consumables selection.

Handling Samples Where Contamination Is a Concern

If your workflow involves samples that could contaminate the pipette or subsequent samples, filter tips provide an additional barrier.

Sensitive Molecular Workflows

Workflows involving nucleic acids or other contamination-sensitive assays may benefit from the additional protection provided by filter tips.

Workflows With Repeated Pipetting

Repeated aspiration and dispensing can create opportunities for aerosols to enter the pipette. Using an appropriate filter tip can help reduce that risk.

Do You Need Filter Tips for PCR?

Do You Need Filter Tips for PCR?

In many PCR workflows, filter tips are recommended because they can help reduce the risk of aerosol-based cross-contamination.

PCR is particularly sensitive to contamination because even small amounts of unwanted nucleic acid can affect downstream results.

However, filter tips are only one part of contamination control.

Good laboratory practices also include:

• Separating pre-PCR and post-PCR areas
• Keeping samples and reactions covered
• Using appropriate pipetting technique
• Changing gloves when necessary
• Cleaning equipment and work surfaces
• Using appropriate pipette and consumable configurations

Thermo Fisher specifically identifies filtered pipette tips as one component of good contamination-control practice for PCR.

Do Filter Tips Improve Pipetting Accuracy?

Do Filter Tips Improve Pipetting Accuracy?

Not necessarily.

A filter does not automatically make a pipette more accurate.

Pipetting performance depends on multiple factors, including:

• Pipette condition
• Pipette calibration
• Tip fit
• Tip geometry
• Liquid properties
• Pipetting technique
• Temperature
• Tip material
• Retention characteristics

Filter tips are primarily used for contamination protection, rather than as a direct accuracy upgrade.

This distinction is important when choosing consumables.

If contamination is not a significant concern for your application, paying more for a filter may not provide a meaningful benefit.

Are Universal Pipette Tips Less Reliable Than Filter Tips?

Are Universal Pipette Tips Less Reliable Than Filter Tips?

No.

Universal and filter describe different characteristics.

A universal tip refers primarily to compatibility, while a filter tip refers to contamination protection.

A universal tip can be manufactured to high quality standards, just as a filter tip can.

When comparing products, look beyond the label and evaluate:

• Fit
• Manufacturing consistency
• Material
• Tip geometry
• Retention
• Cleanliness
• Sterility
• Compatibility
• Intended application

Some manufacturers also offer universal-fit filter tips, combining broad pipette compatibility with aerosol protection.

What About Sterile vs. Filter Tips?

What About Sterile vs. Filter Tips?

These terms are sometimes confused, but they describe different things.

Sterile refers to the microbiological condition of the product.

Filter refers to the presence of a filter designed to reduce aerosol or contamination transfer.

A pipette tip can be:

• Sterile and filtered
• Sterile and non-filtered
• Non-sterile and filtered
• Non-sterile and non-filtered

The right combination depends on the application.

For example, a workflow may require sterile consumables because of microbiological requirements, while another may primarily require aerosol protection.

In some workflows, both requirements may apply.

Sequence BioTech’s current laboratory consumables selection includes both sterile and sterile-with-filter options across several pipette tip product lines.

What Should You Consider When Choosing Pipette Tips?

What Should You Consider When Choosing Pipette Tips?

Before choosing between universal and filter tips, ask these questions.

1. What Are You Pipetting?

Consider the type of sample, reagent, or material being handled.

Some applications are significantly more sensitive to contamination than others.

2. How Important Is Aerosol Contamination Control?

If contamination could compromise results, filter tips may provide an important additional barrier.

3. What Pipette Are You Using?

Always verify tip compatibility.

“Universal” does not mean compatible with every pipette. Compatibility should be confirmed for the specific pipette model and application.

If you’re using a Rainin LTS-compatible workflow, Sequence BioTech’s [LTS Plus Series Benchtop Pipettor] is designed to work with LTS tips and provides 96-channel liquid handling.

4. Do You Need Sterile Tips?

If sterility is required, confirm the supplier’s specifications and packaging.

5. Does Your Application Require Low-Retention Tips?

For certain liquids, low-retention tips can help minimize liquid remaining on the tip surface.

This can be particularly relevant when working with expensive reagents or low-volume samples.

Sequence BioTech’s laboratory consumables selection includes low-binding MultiMax tips.

6. Are You Working With Automation?

Automated liquid handling systems may have more specific requirements around:

• Tip dimensions
• Conductivity
• Rack format
• Tip pickup
• Detection
• Orifice geometry
• Software compatibility

Do not assume that a manually compatible tip is automatically suitable for an automated system.

How Much More Do Filter Tips Cost?

How Much More Do Filter Tips Cost?

Filter tips generally cost more than comparable non-filter tips because they incorporate an additional filter component and may have additional manufacturing or cleanliness requirements.

However, price should be evaluated against the cost of the workflow being protected.

For a contamination-sensitive assay, the cost of failed experiments, repeat testing, lost samples, or delayed results can be much higher than the difference between filtered and non-filtered tips.

For routine workflows where contamination is not a major concern, standard tips may provide a more economical option.

The goal is not to use the most expensive tip.

The goal is to use the right tip for the application.

Can You Use Filter Tips for Routine Liquid Handling?

Can You Use Filter Tips for Routine Liquid Handling?

Yes.

Filter tips can be used for many routine liquid-handling applications.

However, using a filter tip when the workflow does not require additional aerosol protection may increase consumables costs without providing a corresponding benefit.

This is why laboratories should evaluate consumables based on application requirements rather than automatically standardizing on one tip type for every workflow.

Frequently Asked Questions

Frequently Asked Questions

Are filter pipette tips better than universal pipette tips?

Not universally. Filter tips provide an additional barrier against aerosol contamination, while universal tips are primarily designed around broad pipette compatibility. The appropriate choice depends on the workflow.

Are filter tips necessary for PCR?

Filter tips are commonly recommended for PCR workflows because they can help reduce aerosol-based cross-contamination. They should be used alongside other contamination-control practices.

Can universal tips be used with any pipette?

No. “Universal” does not mean compatible with every pipette. Compatibility should be confirmed for the specific pipette model and application.

Do filter tips prevent all contamination?

No. Filter tips can help reduce aerosol-based contamination, but they are not a substitute for proper pipetting technique, cleaning, workspace separation, and other laboratory contamination-control practices.

Are filter pipette tips worth the extra cost?

It depends on the application. For contamination-sensitive workflows, the additional protection may justify the cost. For routine workflows with lower contamination risk, standard tips may be sufficient.

How do I choose the right pipette tip for my lab?

Start with four questions: What are you pipetting? What contamination risks exist? What pipette or automation system are you using? What cleanliness and sterility requirements does the workflow have?

The Right Pipette Tip Depends on the Workflow

The Right Pipette Tip Depends on the Workflow

There is no single pipette tip that is right for every laboratory application.

For routine liquid handling, high-quality universal tips can provide a practical and economical solution.

For contamination-sensitive workflows, filter tips can provide an additional layer of protection against aerosols entering the pipette and potentially affecting subsequent samples.

The best approach is to match the tip to the application, equipment, contamination risk, and required cleanliness level rather than choosing based on brand or price alone.

At Sequence BioTech, we offer laboratory consumables designed to support a range of liquid-handling workflows, including compatible pipette tips and other lab supplies.
