Harvest Right Pharmaceutical Small Freeze Dryer

The Pharmaceutical line is engineered specifically for preserving delicate botanical and pharmaceutical compounds. Where home Pro models are optimized for food preservation, the Pharmaceutical unit uses precise vacuum pressure and temperature control to protect heat-sensitive materials — enzymes, terpenes, and active compounds — that would be degraded by the temperatures used in conventional drying methods.

A complete freeze-dry cycle typically finishes within 20–24 hours, depending on the material and its moisture content. Once started, the process is fully automated — load your trays, press start, and the unit handles the rest.

The Small model processes 3.75–5 lbs of wet material per cycle across its five stainless steel trays. After drying, this yields approximately 0.9–1.25 lbs of finished dry product. Actual yield varies based on the initial moisture content of your material.

The included Premier pump is reliable and well-suited for regular use — oil changes take about two minutes every 20–25 batches. If you're running frequent back-to-back cycles or simply want completely hands-off operation, the oil-free upgrade eliminates all pump maintenance. For high-frequency use, the time savings alone make the upgrade worthwhile.

No — the Small Pharmaceutical runs on standard 110V household power with no special circuit or installation required. It's accessible for most home lab, small commercial, and professional settings right out of the box.

The Small is ideal for those starting out, working with smaller batch sizes, or running specialized runs where processing 3.75–5 lbs per cycle is sufficient. If you're regularly hitting the capacity ceiling and need to run multiple back-to-back cycles, the Medium (7–9 lbs) or Large (12–14 lbs) will deliver better throughput with the same level of precision.

With the Premier pump, change the oil every 20–25 batches using the included vacuum pump oil and filter — about two minutes per change. Wipe down the stainless steel chamber between batches and inspect the door seals periodically. If you upgrade to the oil-free pump, maintenance is essentially eliminated beyond keeping the unit clean.
