WELCOME:

Liquid Nitrogen Generator the Elan2digital. Being the latest generation
of award winning Liquid Nitrogen generators offered by MMR, the
Elan2digital boasts increased production rates, a smaller foot print,
quieter operation, and a digital microprocessor.

The Elan2digital offers a new user friendly interface; including self-

management and error checking to improve overall efficiency, uptime, and
production. By minimizing user intervention, and with the provision of intelligent
feedback and control, the Elan2digital will offer years of quiet, clean, on-hand Liquid
Nitrogen produced directly in your office.

INTENDED USE:

Liquid Nitrogen is needed. Because the Liquid Nitrogen generated does not get
handled by complex industrial processes or trucks, it is extremely clean. This makes it
an ideal solution for research applications, clean rooms, tissue biological sample
preservation, or clinical cryosurgical applications.

PRODUCT OVERVIEW:

direct to the user in their office. This is made possible by advanced Nitrogen
separation and closed-cycle Kleemenko cooler technology. When put together a
production rate of 6-8Liters of high purity, clean Liquid Nitrogen is possible. The new
built in self-management system provides peace of mind that the Elan2digital is
always performing at its peak, and Liquid Nitrogen is always available on-demand and
on-time.

Congratulations on your purchase of the world’s smallest office

The Elan2digital systems are intended for indoor use only where clean

The Elan2digital produces Liquid Nitrogen straight from the air

The system is comprised of:

 Air Compressor unit with Dryer (PSA)

 Elan2Digital Liquefier Unit

LIQUID NITROGEN SAFETY:

highest level of user safety in mind. They are also designed to minimize direct handling
of Liquid Nitrogen by the user. However care must be taken to ensure no contact is
made with the cryogenic fluid during Liquid Nitrogen removal from a leak or splash.

HANDLING:

vessels which contain cryogenic fluids. The extremely cold fluid can cause severe burns
if even momentary contact with human skin is made. Always wear adequate eye
protection and gloves when handling cryogens.

Never allow any unprotected part of the body to touch un-insulated pipes or

CONTAINMENT:

Fluids. MMR assumes no liability for injuries caused through improper handling or use
of the provided Cryogen Storage Vessels. MMR have thoroughly tested and approved
the following Cryogenic Storage Vessels for use with this system:

 Brymill CRY-AC® Series for cryosurgery.
 MVE Dewar’s from PrincetonCryo.

Never carry Liquid Nitrogen in a vessel not properly suited for Cryogenic

RISK OF EXPLOSION

NITROGEN THAT DOES NOT HAVE ADEQUATE VENTILATION HOLES OR A PRESSURE RELIEF
DEVICE.

SPECIFICATIONS:

(-198°C). It can cause rapid suffocation when concentrations are sufficient to reduce

oxygen levels below 19.5%. Contact with liquid or cold vapors can cause severe
frostbite. Cold vapors in the air will appear as a white fog due to condensation of
moisture. While this may indicate the presence of the gas it should not be used to
determine its concentration in the atmosphere. Oxygen concentrations must be
monitored in the release area. All cryogenic liquids produce large volumes of gas when
they vaporize. One volume of Liquid Nitrogen will expand to produce 696.5 equivalent
volumes of gas.

Liquid Nitrogen is a colorless, odorless, extremely cold liquid and gas

MSDS-OSHA: Not established.

ACGIH: Simple Asphyxiate.

CAS NUMBER: 7727-37-9.

These liquid nitrogen generators have been designed with the

: NEVER CAP OR SEAL A STORAGE VESSEL FOR LIQUID

CHOOSING A LOCATION: To ensure optimal operation and ongoing performance of the
unit, the following guidelines must be met:

 Room temperature should not exceed 25 C (77 F).
 Well ventilated.
 The room should be free of dust and exhaust from other instrumentation.
 The room should be of low humidity (<70% Rel Humidity).
 A stable dedicated power source (Extension cords should be avoided).

HANDLING:

 Never tilt or tip the unit.
 Never move or JAR the unit when running.
 Never block or obstruct the vents; doing so will overheat the unit and in some

cases cause permanent damage. Temperature recording devices have been
implemented for warranty purposes.
