Shelf configuration
| Shelves | Shelf area | Shelf clearance |
|---|---|---|
| 1 shelf | 1,394 cm² (1.5 ft²) | 328 mm (12.9 in) |
| 2 shelves | 2,880 cm² (3.1 ft²) | 158 mm (6.2 in) |

Shelf size (W × D): 274.3 mm × 520.7 mm · Optional shelf latching increases clearance — on a 3-shelf unit with two shelves latched, 307 mm.
SP recommends a 61 cm clearance around all sides of the unit for serviceability; if machines are placed side by side, increase the minimum clearance to 121.9 cm.
SP VirTis Genesis 35L is available in Thailand from Thai Unique, with installation, calibration and after-sales service handled by our own team here in the country. For details and a quotation, call 0-2629-0191-6 or email customer.service@thaiunique.com.
All specifications are taken from the manufacturer’s own documentation and are based on units operating at an ambient room temperature of approximately 20 °C; SP recommends an operating range of 15-25 °C. SP VirTis reserves the right to change specifications without notice.
SP VirTis Genesis 35L in Thailand

Where a pilot freeze dryer is used in Thailand
Based on the specifications above, the Genesis 35L suits laboratories that:
- Need to dry high-moisture batches without breaking them into several runs — the condenser capacity (the total amount of ice it can hold) is at least 35 L, and its ice removal rate, a separate figure, is at least 20 L per 24 hours.
- Work with recipes that call for tightly held shelf temperatures, on shelves reaching ≤ -67 °C at 50 Hz and holding any setpoint from -55 to 65 °C within ± 0.5 °C.
- Want to carry a proven research recipe up to larger batches on one machine, adding shelves from one to six to take total shelf area from 1,394 cm² to 8,547 cm², with top-down hydraulic stoppering offered on units of up to five shelves.
- Need to place the unit in a cleanroom or a tight service aisle — a narrower 64 cm-wide build is available, fitted with a 20.3 cm vapor port, which is the opening between the product chamber and the condenser. For servicing, 61 cm of space is recommended around every side.

Frequently asked questions
How many shelves can the Genesis 35L be built with, and how does that change the usable space?
It can be configured with one to six shelves, giving 1,394 cm² up to 8,547 cm² of total area, while clearance between shelves drops from 328 mm down to 46 mm as shelves are added. If you also want the stoppering option, it is offered on units of up to five shelves — our team here can help you settle on the right layout.
Why buy SP VirTis Genesis 35L from Thai Unique rather than direct from the manufacturer?
Because the people who look after it are here. Installation, calibration, scheduled maintenance, repairs with genuine parts and operator training are all handled by our team in Thailand, without routing every request overseas.
Can we test our own samples before deciding?
Yes. Our sample testing and method verification service runs your real samples so you can see the results this pilot freeze dryer gives on your workload before you buy.
How much does it cost, and how do we request a quotation?
Pricing depends on the configuration, accessories and the scope of work in your laboratory. Tell our sales team what you need to analyse and how many samples you run per day, and we will propose a configuration together with lead time and service terms.
