From Lab Bench to Production Line

Scaling up your biotech or agri-input product can be exciting — but it’s also a critical phase where early decisions can make or break future success. Moving from lab bench to factory floor means translating precise, small-batch methods into repeatable, large-scale manufacturing — without losing what makes your product work.

Here’s a look at what typically changes when you scale up — and just as importantly, what should stay the same.

What Shouldn’t Change

The whole point of scale-up is to make more of what works — not to lose sight of what made your product effective in the first place. Whether it’s a biostimulant, seed coating, or microbial treatment, the product should still perform as intended.

What this means:
Any adjustments during scale-up should preserve the product’s core action. If it changes noticeably, something’s gone wrong in the process.
However, scale-up can introduce new physical variables — like mixing intensity, temperature control, or shear forces — that may affect performance in subtle ways, especially for complex or sensitive formulations. That’s why it’s essential to define clear performance criteria and test the first scaled-up batches thoroughly under realistic use conditions.

No matter who manufactures your product, your formulation should remain yours. IP protection is critical — especially in the competitive biotech space.

What this means:
Choose a toll manufacturer who treats confidentiality as non-negotiable. A partner who doesn’t develop or sell their own products is less likely to have overlapping interests — reducing the risk of unintentional IP conflicts. It’s also good practice to have a clear Non-Disclosure Agreement (NDA) in place before sharing any formulation details, even at the enquiry stage.

Make sure any samples, process tweaks, or raw material substitutions are documented and agreed upon, so ownership of the final product stays with you. A reputable toller will be transparent about their role: manufacturing to your specifications, supporting scale-up where needed, and keeping your formulation confidential at every stage.

Scaling up shouldn’t mean cutting corners. The same level of care, cleanliness, and compliance that you’d expect in the lab should apply in the factory — even if the processes look different.

What this means:
A good manufacturer will have robust quality systems in place — including documented Standard Operating Procedures (SOPs), batch traceability, and rigorous checks throughout production. This might include in-process testing (e.g. pH, viscosity, dispersion), final batch sampling, and retained samples for reference.

Look for signs of a strong quality culture: do they calibrate equipment regularly? Do they have dedicated QA staff? Are they accredited to ISO or similar standards? These are all positive indicators that your product will be handled with the same precision you’d expect in a lab environment.

Ask how safety is managed too. For example, how are allergens or microbial materials handled? What controls are in place to prevent cross-contamination?

Reputable toll manufacturers will be happy to walk you through their systems, answer your technical questions, and demonstrate how they’ll maintain your product’s integrity at scale.

What Does Change

You may use a stirrer and water bath in the lab — but in production, that becomes jacketed vessels, high-shear mixers, and automated filling lines. Equipment behaves differently, and process steps may need adapting.

What this means:
Processes that work on a small scale don’t always behave the same when multiplied by hundreds or thousands of litres. Blending times, shear forces, heating rates, and ingredient addition order may all need to change to suit industrial equipment — and to ensure consistency from batch to batch.

For example, an ingredient that disperses easily with a lab stirrer might clump or separate in a high-volume tank if the addition rate isn’t adjusted. Or a product may be made in the lab using a 2 pot process – this will add significant time and complication to a factory production and would be much more efficient (and cheaper) if a 1-pot method can be used at scale. You don’t have to solve these problems alone. A good toll manufacturer will translate your lab method into a viable production process — testing, tweaking, and validating as needed — while keeping you in the loop. Their job is to preserve what works while adapting how it’s done, using scale-appropriate equipment and techniques.

Lab supplies often come in small, high-purity containers. In manufacturing, your materials might arrive in drums, IBCs, or bulk bags — and how they’re stored, handled, and even poured can affect consistency.

What this means:
Bulk materials behave differently from small lab packs. Powders may settle or compact in storage. Liquids might need stirring before use, or special containment to avoid contamination. These are things your toll manufacturer will consider when designing the process.

It’s also important to know that commercial-grade materials sometimes vary slightly between batches — in colour, particle size, or concentration. Your specification should allow for this, especially if you’re scaling quickly or sourcing at larger volumes. Deionised water may be used in the lab but will use of tap water in larger production volumes affect stability or performance? A good toller will help spot anything that could affect performance and suggest ways to manage it, such as pre-blending, filtering, or tighter incoming QC checks.

Some costs go down at scale (e.g., price per litre), but others go up — like packaging, waste handling, and QA requirements. Unexpected inefficiencies can also creep in if the product is difficult to process.

What this means:
Scale can unlock savings, but it’s rarely a straight line. A slight change in viscosity might slow down filling lines. A granular material might not flow cleanly into bags. Packaging choices can affect everything from output speed to pallet stability.

That’s why early-stage optimisation is so valuable. A small tweak — to a pouring spout, bag liner, or additive ratio — could reduce waste, speed up production, or improve how the product performs for the end user. Your manufacturer should work with you to find practical efficiencies without compromising product integrity.

What’s fine for internal samples or lab trials won’t cut it for products going into distribution. Labels must be accurate and legally compliant, and packaging needs to protect the product throughout its shelf life.

What this means:
Before you move into production, you’ll need to have the full packaging specifications ready — including container size, closure type, labelling layout, and regulatory details. That includes things like CLP hazard symbols, batch codes, and best-before dates where applicable.

Make sure your Safety Data Sheets (SDS) are up to date, and check whether there are any sector-specific labelling requirements (e.g., for biostimulants or microbial products). A good toll manufacturer can advise on packaging compatibility and flag common compliance issues, but the final responsibility for regulatory accuracy lies with you — so it’s worth getting this nailed early.

Lab notebooks are great for experiments — but production needs formal, traceable records. Everything must be documented, verified, and accessible.

What this means:
Expect more structure around record-keeping. Your toll manufacturer should maintain detailed batch records that cover raw material lot numbers, process steps, operator sign-offs, QC results, and any deviations. These aren’t just for traceability — they help ensure consistency and support your own regulatory obligations, especially if your product is subject to audit or registration.

iscuss it upfront so it becomes part of the standard process.

You’ll likely be less hands-on than you were in the lab — but that doesn’t mean you lose control.

What this means:
As you move into outsourced manufacturing, your role shifts from mixing and measuring to reviewing specs, approving changes, and interpreting QC results. A good manufacturing partner will keep you informed and involved — especially when making decisions that could affect performance or compliance.

et the tone early: ask questions, request documentation, and stay part of the conversation. The best outcomes come from collaboration — not from handing everything off and hoping for the best.

Scaling up isn’t just about producing more — it’s about protecting what matters most: your product, your IP, and your reputation. The right toll manufacturer will act as a technical partner, not just a service provider. Ask questions, stay involved, and choose a team that understands both the science behind your product and the practical realities of making it work at scale.
