Harvest Right Large Scientific Pro Freeze Dryer

Programmable Benchtop Lyophilization for Labs and Product Development, 6 Trays

Research and product development depend on a freeze-drying process you can control and repeat, which a food freeze dryer's automatic cycle doesn't provide. Harvest Right's Scientific Pro line gives you control over every stage, from how fast material freezes to how shelf temperatures rise during drying. Profiles can power the condensing unit and vacuum pump on and off automatically as the process moves through each step.

The Large size steps up to six trays and a 2.7-gallon holding capacity for labs and producers that run larger batches or more samples per cycle. Confirm its electrical requirements with Harvest Right before installation.

Key Features & Benefits

• Programmable freeze control — set the rate of freeze, the final freeze temperature and how long material holds at that temperature before drying begins.
• Staged shelf temperatures — program up to five shelf temperatures to dry in phases, for example starting at 10°F and finishing at 70°F.
• Recipe customization — build processes with up to 10 thermal treatment steps and 12 drying steps, saved as reusable profiles.
• Cycle logging and live readouts — the system logs pressure and temperature through every stage and shows them in real time on a 4.3 in full-color touchscreen.
• 6 stainless steel trays — each tray measures 9 x 20.5 x 0.75 in, with a 2.7 gal (10.2 L) holding capacity; ships with the XL Premier industrial vacuum pump.

Who Should Use the Scientific Pro

Scientific Pro freeze dryers suit university and research labs, pharmaceutical and nutraceutical developers, and food product developers who need documented, repeatable lyophilization. Growers and producers can also use them for precise drying of herbs and other plant material.

About the Harvest Right Large Scientific Pro

The Large Scientific Pro is part of Harvest Right's Scientific line, offered in Medium, Large and X-Large sizes. It is a bench or tabletop lyophilizer with a stainless steel collector rated to -46°F and a three-year limited warranty.

Frequently Asked Questions

What is lyophilization?

Lyophilization is the laboratory term for freeze drying: a sample is frozen and then its ice is removed under vacuum by sublimation. Because the material is never heated much, its structure and many sensitive compounds are preserved. Scientific freeze dryers add the process control labs need to repeat results.

How does a Scientific model differ from a Harvest Right home freeze dryer?

Home freeze dryers run an automatic cycle designed for food. Scientific models let you control freeze rate, final freeze temperature, hold time and up to five staged shelf temperatures, and they log pressure and temperature for every run. That control suits research, product development and samples that need a documented, repeatable process.

How do I keep the vacuum pump running well?

The included Premier industrial vacuum pump uses oil that should be filtered or changed on a regular schedule, and an oil filter ships with the unit for that purpose. Harvest Right also offers an oil-free pump upgrade for labs that prefer no oil maintenance. Check the oil level and clarity in the sight glass between runs.

Can it be used for food and plant material as well as lab samples?

Yes. The same programmable process works for food product development, herbs and other plant material, and research samples. Saved profiles let you switch between material types without rebuilding the process each time.

What comes with the Large Scientific Pro?

It ships with the freeze dryer, the XL Premier industrial vacuum pump, vacuum pump oil, an oil filter, a set of 6 stainless steel trays and the Guide to Freeze Drying. Wi-Fi monitoring is not included and is sold separately as the Harvest Right Wi-Fi Upgrade Kit.
