The SP VirTis Ultra 50L carries the largest condenser in the Ultra pilot range — ≥ 50 litres, with 0.93 m² of condenser surface area — for work involving substantial amounts of water or solvent. Despite that, the unit is only 64 cm wide, so it fits where floor space is tight.
Key features
- Compact design for easy installation, with a narrow footprint (cleanroom configuration available)
- Single product chamber design allows for larger batches and product uniformity
- Available with a Merlin or LyoS 2.0 control system
- Optional bottom-up hydraulic stoppering system

Where the pilot freeze dryer is used in Thailand
Based on the specifications above, the Ultra 50L suits laboratories that:
- Need to condense large vapour loads in one run — the condenser holds ≥ 50 L across 0.93 m² of surface and lays down ice at ≥ 0.83 L/hour, reaching ≥ 20 L over 24 hours.
- Work with aqueous or solvent-based formulations that call for deep cold, with shelves down to ≤ -67 °C at 50 Hz and a condenser reaching ≤ -82 °C.
- Want to keep a batch consistent from tray to tray, holding shelf temperature uniformity of ± 1.0 °C anywhere across a control range of -55 to 65 °C.
- Need to place pilot capacity in a tight lab or cleanroom, since the cabinet is 64 cm wide and can be ordered with bottom-up hydraulic stoppering.

Frequently asked questions
How much vapour can the Ultra 50L take in a 24-hour run, and how quickly does it get down to temperature?
The condenser holds ≥ 50 L and deposits ≥ 20 L of ice over 24 hours, cooling from 20 °C to -45 °C in ≤ 35 minutes while the shelves drop to -40 °C in ≤ 40 minutes. Our team can go through your cycle and utility requirements with you before you order.
Why buy SP VirTis Ultra 50L 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.
