Reducing pipette tip waste requires looking beyond the tip itself.

A conventional rack of 96 pipette tips includes several plastic components: the tips, the support tray, the outer box and, in many designs, a plastic lid. Although the exact weight varies by manufacturer and tip format, a standard rack and box can contain roughly 50 to 100 grams of plastic packaging, separate from the tips themselves. In some automated tip products, the rack, carrier and packaging account for more than half of the total product weight.

That means cleaning and reusing pipette tips can eliminate a significant portion of a lab’s consumable waste, but the rack holding those tips remains another opportunity for improvement.

IonField Systems’ partnership with PulpFixin brings those two opportunities together.

Combining Reusable Tips with Recyclable Racks

IonField Systems develops plasma-based systems that allow laboratories to clean pipette tips for reuse. Our PureTIP One system uses a continuous flow of plasma up and through each tip, including filtered and conductive tips, destroying residual contaminants without producing liquid cleaning waste or requiring a drying cycle.

Once the tips have been cleaned, however, they still need somewhere clean and practical to go.

Through our partnership with PulpFixin, laboratories can place cleaned pipette tips into new, plastic-free racks designed to replace conventional polypropylene tip boxes. PulpFixin’s pipette tip racks are manufactured from paper-based materials and can be recycled with standard paper and cardboard streams. They are also re-pulpable and compatible with industrial composting systems.

In addition to providing standard solutions, we offer the capability to design and produce a specific product tailored to your needs. Whether your workflow requires a customized rack format, specialized handling requirements or integration with existing laboratory processes, our teams can work with you to develop a solution that supports your sustainability and operational goals.

The result is a more complete approach to pipette tip sustainability: reuse the component that must maintain precise liquid-handling performance and replace disposable plastic packaging with a recyclable alternative.

Why a New Rack Can Be Valuable

In some workflows, cleaned tips can be returned to their original rack. That may be the simplest option when the rack remains clean, undamaged and suitable for continued use.

In other situations, placing cleaned tips into a new rack offers important operational benefits.

A new rack provides a clearly defined starting point for the next use cycle. It can make it easier to distinguish cleaned tips in PulpFixin racks from new tips in their original plastic packaging, maintain orderly inventory and prevent damaged or visibly soiled packaging from returning to the workflow.

This separation can be particularly valuable in centralized cleaning operations. A laboratory may collect used tips in their original racks, clean the tips in batches and then transfer them into new racks before sending them back to individual work areas. The new rack becomes a simple visual indicator that the tips have completed the cleaning process and are ready for reuse.

Instead of asking laboratory staff to inspect and manage aging plastic boxes indefinitely, the tips can begin each reuse cycle in clean, uniform packaging.

Reducing More Than Tip Waste

Pipette tip reuse changes the waste equation significantly. If a rack of 96 tips is used ten times, the laboratory avoids purchasing and disposing of nine additional sets of tips.

But if every reuse cycle still requires another conventional plastic rack, part of the waste reduction is lost.

PulpFixin’s racks address that remaining packaging burden. Their paper-based construction directly replaces conventional plastic rack components while retaining the durability and handling characteristics required for laboratory workflows. PulpFixin has also developed automation-ready racks designed to integrate into existing liquid-handling environments without requiring equipment modifications.

This allows laboratories to reduce waste on two levels:

The pipette tips are cleaned instead of discarded, while the replacement rack can enter a more accessible paper and cardboard recycling stream rather than becoming another piece of laboratory plastic waste.

Making Reuse Easier to Manage

For reuse to work at scale, it cannot depend on complicated sorting systems or constant intervention from laboratory staff. It must fit into the workflow as naturally as opening a new box of tips.

PureTIP One was designed with that goal in mind. The standalone, automation-ready system can clean up to 70 racks per hour, and because plasma cleaning does not leave tips saturated with cleaning fluid, there is no drying stage before they can be returned to service.

PulpFixin’s racks complement that process by providing a practical destination for the cleaned tips. A lab can collect used tips, clean them, place them into new recyclable racks and return them to the workflow in a familiar format.

The process does not ask scientists to change how they pipette. It changes what happens around the pipette tip.

A More Complete Consumables Strategy

Laboratory plastic reduction is sometimes approached one item at a time: lighter packaging, recyclable boxes, refill systems or lower-plastic consumables. Each can help, but the greatest impact comes from considering the entire consumable lifecycle.

The partnership between IonField Systems and PulpFixin connects two complementary strategies.

IonField extends the useful life of the pipette tip through plasma cleaning. PulpFixin provides an alternative to the disposable and bulky plastic infrastructure traditionally used to hold and transport those tips.

Together, the technologies allow laboratories to move beyond simply purchasing a slightly less wasteful disposable product. They create a workflow in which the high-performance consumable is reused and its supporting packaging is designed for a more responsible end of life.

With the ability to design and produce solutions customized to individual laboratory requirements, IonField Systems and PulpFixin can help organizations develop reuse workflows that fit their specific applications rather than forcing laboratories to adapt to a one-size-fits-all approach.

That is what practical laboratory sustainability should look like: less plastic entering the lab, less material leaving as waste and no need to compromise the workflow in between.
