GMP Freeze Dryer

Flexible shelf-count GMP freeze dryer in the Command F series, using 450 x 600 mm shelves for pharmaceutical vial lyophilization, stoppering workflow, matched condenser sizing, and validation documentation support.

Model designation: Command F configurations use SJ-xxxF(T) as the primary public model pattern. The corresponding SJIA-xxxF(T) pattern may appear in factory records, nameplates, quotations, or earlier technical documents; both identify the same SJIALAB equipment configuration.

Command F Flexible Shelf GMP Freeze Dryer

The Command F Flexible Shelf GMP Freeze Dryer is a configurable pharmaceutical lyophilizer built around 450 x 600 mm shelves. It is designed for buyers who compare shelf count and vial loading first, while still requiring real GMP engineering around condenser capacity, total ice load, vapor path, vacuum performance, stoppering workflow, and validation documentation.

450 x 600 mm shelf format: more usable shelf area per shelf than many compact pilot lyophilizer platforms.
Flexible shelf count: fewer shelves for multiple vial formats; more shelves for high small-vial count.
Matched condenser design: final capacity is confirmed by fill volume, total water load, condenser margin, refrigeration package, vapor path, and cycle target.
GMP workflow: stoppering, recipe control, batch report, audit trail, electronic signature, and 21 CFR Part 11-ready SCADA options.

Model Positioning

This product page should help the customer choose a direction before sending an inquiry. The shelf-count language is useful for US buyers, but the final recommendation should still be confirmed by engineering review.

Vial Loading Planning

Many customers ask how many vials can be loaded before they ask about refrigeration theory. The table below uses SJ Scientific's actual 450 x 600 mm shelf layout data for early planning. Final capacity should still be confirmed after reviewing the vial drawing, stopper drawing, fill volume, expected ice load, loading method, condenser margin, and target cycle time.

Example 450 x 600 mm shelf layout for 2R / 3R / 4R vials. Other vial sizes and per-shelf counts are listed below.

Vial Size and Loading Capacity per Shelf

Vial	OD	Glass Vial Height	Vials / Shelf on 450 x 600 mm Shelf
2R	16 mm	35 mm	1,036
3R	16 mm	40 mm	1,036
4R	16 mm	45 mm	1,036
6R	22 mm	40 mm	540
8R	22 mm	45 mm	540
10R	24 mm	45 mm	450
15R	24 mm	60 mm	450
20R	30 mm	55 mm	300
25R	30 mm	65 mm	300
30R	30 mm	75 mm	300
50R	40 mm	73 mm	165
100R	47 mm	100 mm	108

Planning note: OD and height are common vial planning dimensions. Loading capacity is based on SJ Scientific's 450 x 600 mm shelf layout. Actual vial count can change with vial supplier tolerance, tray design, loading method, stopper style, and required edge clearance.

Estimated Total Vial Positions by Shelf Count

This table multiplies the actual per-shelf loading count by shelf count. It is useful for quick buyer conversations, but it is not a clearance approval. Taller vials, lyophilization stoppers, trays, and stoppering travel must be checked before selecting a high shelf-count configuration.

Vial	Glass Height	Vials / Shelf	4 Shelves	6 Shelves	8 Shelves	10 Shelves	13 Shelves
2R	35 mm	1,036	4,144	6,216	8,288	10,360	13,468
3R	40 mm	1,036	4,144	6,216	8,288	10,360	13,468
4R	45 mm	1,036	4,144	6,216	8,288	10,360	13,468
6R	40 mm	540	2,160	3,240	4,320	5,400	7,020
8R	45 mm	540	2,160	3,240	4,320	5,400	7,020
10R	45 mm	450	1,800	2,700	3,600	4,500	5,850
15R	60 mm	450	1,800	2,700	3,600	4,500	5,850
20R	55 mm	300	1,200	1,800	2,400	3,000	3,900
25R	65 mm	300	1,200	1,800	2,400	3,000	3,900
30R	75 mm	300	1,200	1,800	2,400	3,000	3,900
50R	73 mm	165	660	990	1,320	1,650	2,145
100R	100 mm	108	432	648	864	1,080	1,404

Clearance note: vial height is glass body height only. A partially inserted lyophilization stopper, loading tray, and stoppering clearance can add height. For 13-shelf high-density layouts, SJ Scientific should confirm the customer's vial and stopper drawings before quoting the final configuration.

Shelf Count Versus Drying Capacity

Shelf count is not the same as freeze-drying capacity. When shelves are fully loaded, more shelf area normally means more product water and more vapor load. The condenser, refrigeration package, vapor path, and vacuum system must be matched to the actual batch requirement.

Fewer shelves	More vertical clearance and more flexibility for different vial sizes, stoppers, trays, or product formats.
More shelves	More vial positions for small vials when the vial height, stopper height, and loading method are already confirmed.
Final sizing	Confirmed by fill volume, total ice load, condenser capacity, refrigeration package, vapor path, vacuum pump, and target cycle time.

FAQ

Is shelf count the same as freeze dryer capacity?

No. Shelf count affects vial positions and loading density, but true freeze-drying capacity depends on shelf area, fill volume, total ice load, condenser capacity, vapor path, vacuum system, and target cycle time.

Why choose fewer shelves?

Fewer shelves provide more vertical clearance and more flexibility for different vial sizes, stopper heights, trays, or product formats.

Why choose more shelves?

More shelves can increase vial positions for small vials when the vial height, stopper height, loading method, and condenser margin are confirmed.

Can one GMP freeze dryer process different vial formats?

Yes, but the shelf spacing should be selected around the tallest vial and stopper combination expected in routine use.
