Guaranteed to Meet Manufacturer Specs. 90-Day Warranty.
AdID: 15235

Availability: In stock


Refurbished & Calibrated VirTis 35EL Freeze Dryer
Meets Manufacturer Cooling & Vacuum Spec.

Thoroughly refurbished with numerous new parts and a 90-day warranty, this Virtis
Freezemobile 35EL 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, & Calibrated

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 calibrate the system so you will get excellent performance on day one.

- New condenser chamber glass door and door seal
- New compressor and evacuated both compressors
- New vacuum and drain hoses
- New side panels and evaporator cover
- New pipe and condenser insulation
- Recharged refrigerant
- Leak testing performed

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

Exceptional Internal Condition with New Insulation 
Expect Long-Usage out of a Healthy Looking Instrument

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: One of the compressors is brand new and the low stage 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 side panels, evaporator
cover, insulation, compressor, and chamber door, this system not only runs flawlessly,
but it also looks like a new instrument.

Rebuilt Vacuum Pump with Extended Warranty

This freeze dryer has been outfitted with a rebuilt 2015 Adixen 2021i vacuum pump
and oil mist eliminator that is successfully pulling the system down to 11 millitorr.
This pump carries a 1-year extended warranty, providing you the confidence that
you’ll be protected in case of breakdown.

Meeting Refrigeration and Vacuum Specifications

To ensure the refrigeration of this freeze dryer is operating at manufacturer specification
of -85°C, our technician performed a full evacuation of the refrigeration system and
refilled the system with new refrigerant.

The recharge process involved the following:

- 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

During testing and calibration this freeze dryer was consistently able to reach -85°C
with no difficulty at 20°C ambient room temperature. As for the vacuum system, the
manufacturer specification for the lowest system vacuum is ≤15mT and this system
achieved 11mT with the included pump.

Equipped and Ready for Operation

As long as you have compatible freeze drying vessels, you will be able to immediately
start freeze drying with this system. With the included 16 shut-off valves, you can use
16 ports of the 48-port tree manifold, but you will need to purchase 32 more valves
in order to utilize the full capacity of the manifold.

- VirTis Freezemobile 35EL Freeze Dryer
- 48-Port Tree Manifold w/ 16 shut-off valves
- 2015 Adixen 2021i Vacuum Pump w/ oil mist eliminator
- OEM Tools 1.4G fluid evacuator and tubing
- Attached power cable

90-Day Warranty for your Peace-of-Mind

We realize that buying pre-owned can be unnerving, so we include a 90-day warranty
on our equipment to protect you against any equipment failure or defects. If anything
goes wrong, our in-house support is only a phone call away.

Fully-Featured for High Throughput

Not only is this system capable of processing large sample batches with its 35L
condenser chamber and 48-port tree manifold, but it also comes paired with a fluid
evacuator that makes changing the vacuum pump oil remarkably clean and efficient.

- Large capacity 35L condenser chamber
- 48-port tree manifold for large-batch processing
- 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
