Guaranteed to Meet Manufacturer Specs. 90-Day Warranty
AdID: 14281

Availability: In stock


Refurbished and Calibrated VirTis 12EL Freeze
Dryer - Meets Manufacturer Cooling and Vacuum

Thoroughly refurbished with numerous new parts and a 90-day warranty, this Virtis
Freezemobile 12EL freeze dryer is the affordable but reliable solution for equipping
your lab for years of lyophilization. It’s in excellent physical condition with very little
yellowing and a clean look and guaranteed to meet manufacturer specifications.

This freeze dryer is an instrument you can be proud to have in your lab and can be
trusted for reliable service.

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 door and door seal
- 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 - Giving
You Confidence In Your 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: The compressors also show 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.

Check the pictures to see the details for yourself.

In Excellent Cosmetic Condition: Feel proud of the way your
lab looks

This freeze dryer is in excellent shape, lacking any sort of major dings or damages
from being relocated and suffering impact. There is some minor wear on the exterior
and it does have the typical yellowing that we see in freeze dryers from VirTis, but
nothing out of the ordinary.

The only cosmetic complaint is a minor gash out of to the top panel of the instrument
that you can see in the 11th picture of the gallery.

Overall, this freeze dryer was well taken care of and will look great in your lab.

Rebuilt Vacuum Pump with Extended Warranty

This freeze dryer has been outfitted with a rebuilt Adixen 2021i vacuum pump that
is successfully pulling the system down to 11 millitorr. A healthy vacuum pump means
you can can rely on this freeze dryer to produce consistent freeze drying results
without pressure failure ruining your samples.

This pump carries a 1-year extended warranty, providing you confidence that you’ll
be protected in case of breakdown.

This pump also includes an improvement to VirTis’s stock vacuum pump design:
an oil mist eliminator and recycler. Filtering the mist and recycling it right back
into the vacuum pump makes pump maintenance even simpler!

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 -91°C
with no difficulty. 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 valves, you can use the full capacity of the 16-port tree manifold.

- VirTis Freezemobile 12EL Freeze Dryer
- 16-Port Tree Manifold w/ 16 Shut-off valves
- Adixen 2021i Vacuum Pump
- OEM Tools 1.4G Fluid Evacuator and Tubing

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 16-port tree
manifold, but it also comes paired with a fluid evacuator that makes changing the vacuum
pump oil remarkably clean and efficient.

- 16-port tree manifold for large-batch processing
- 1.4 Gallon Fluid Evacuator for clean and efficient oil change
