VirTis Genesis 25EL Freeze Dryer - Guaranteed to Meet Manufacturer Cooling and Vacuum Specifications

Thoroughly refurbished with numerous new parts and a 90-day warranty, this Virtis Genesis 25EL freeze dryer is the affordable but reliable solution for equipping your lab for years of lyophilization. It’s in excellent physical condition and guaranteed to meet manufacturer specifications.

Refurbished - Brand New Parts & Tested to Specification

Our freeze dryer refurbishment process is more than just returning the instrument to working condition. We install brand new parts, recharge the refrigerant, test for leaks, and make sure everything is performing at or beyond specification so you will get excellent performance on day one.

- New vacuum and drain hoses
- New condenser chamber door seal
- New front evaporator cover
- New pipe and condenser insulation
- Recharged refrigerant
- Leak testing performed

After refurbishment, our technician thoroughly inspected and tested this system to ensure that it would be running perfectly when it enters your lab.

Exceptional Internal Condition with New Insulation

Insulation: Over time, the insulation in freeze dryers will break down and fall apart due to moisture build-up and often needs replaced, so our technician has replaced all old insulation with brand new insulation. This includes:

- Pipe insulation
- Condenser insulation

Refurbished insulation means that you get an instrument with a long life ahead without worrying about heat loss issues.

Compressors: The compressor shows very little paint peeling or wear. The lines coming into the compressor get quite cold, so condensation freezing on the lines breaks down that part of the compressor, but evidence of this is minimal in this freeze dryer.

In Excellent Condition - Will Look Great in Your Lab

This freeze dryer is in excellent shape, lacking any sort of major dings or damages. With many of the parts being entirely new, including the condenser door seal, vacuum hoses, drain hoses, door handle, front evaporator cover, pipe and condenser insulation, this system not only runs flawlessly, but it also looks like a new instrument.

Meeting Refrigeration and Vacuum Specifications

To ensure the refrigeration of this freeze dryer is operating at manufacturer specification, our technician performed a full evacuation of the refrigeration system and refilled the system with new refrigerant.

This freeze dryer is consistently able to reach below -70°C shelf temperature and to the -85°C condenser temperature at 24°C ambient room temperature, both temperatures meeting manufacturer specification.

As for the vacuum system, the manufacturer specification for the lowest system vacuum is ≤15mT and this system performed beyond that with the included vacuum pump.

If you’re curious what our recharge process involves, here are the steps:

- Vent freeze dryer of refrigerant
- Apply 250-micron vacuum to test for leaks, remove debris, and boil off moisture in lines
- Nitrogen purge three times to clear lines for preventative maintenance
- Refill freeze dryer with new refrigerant
- Confirm freeze dryer is operating to specification

Equipped and Ready for Operation

This freeze dryer is a complete system and ready for use. It even comes with a fluid evacuator and fluid pump to make vacuum pump oil changes cleaner and faster, minimizing downtime of your freeze dryer. The following comes with this system:

- VirTis Genesis 25EL Freeze Dryer
- Leybold Trivac D16B Vacuum Pump
- OEM Tools 1.4G Fluid Evacuator and Fluid Pump
- Attached Power Cable

Fully-Featured for High Throughput

Not only is this system capable of processing large sample batches with its 25L condenser and spacious 2 shelf chamber, but it also comes paired with a fluid evacuator that makes changing the vacuum pump oil remarkably clean and efficient.

- Large capacity 25L condenser chamber
- 1.4 Gallon Fluid Evacuator for clean and efficient oil change
- Easy access for vacuum pump maintenance
- Front-facing drainage valve for condenser chamber, simplifying drainage
- Smooth-walled condenser chamber for speedy defrost cycle
