OptistatDry TLEX model - the new optical cryostat for spectroscopy

An ever growing number of institutes are choosing cryogen free optical cryostats such as the OptistatDry. These decisions are driven by a number of important factors. Use the following online cost calculator to find out the annual saving you can have, simply by switching over to a Cryofree OptistatDry:

Just answer the following question to discover how much you could save by making the switch today:

1. What is your current cost per litre of liquid cryogen?

2. Typically, how many hours of experimentation per week?  HOURS

3. How many weeks in the year will your experiment be running for?  WEEKS

 

Important factors to consider

Cost of liquid cryogens

 

The cost of liquid cryogens continues to rise placing an increasing financial burden on institutes. The OptistatDry uses no liquid cryogen at all, and this could save you a substantial amount of money compared to using a wet cryostat. The calculator above can show you the saving you can have.

Availability of liquid cryogens

 

Scheduling experiments is difficult but having to factor in when you will have liquid cryogen makes it even harder. When the rate at which you can publish papers is limited by the availability of liquid cryogens, it is time to consider a cryogen free OptistatDry. As long as you have electrical power you can run cryogenic experiments 24 hours a day, 365 days a year, dramatically increasing the number of experiments you run and the amount of data you collect.

Increase your efficiency and publish more papers with an OptistatDry. 

Hazards of liquid cryogens

 The hazards of using liquid cryogens are well known and include:

  • Asphyxiation due to the displacement of air
  • Fire risk due to condensation of liquid oxygen
  • Risk of explosion due to blockage of outlets from cryogenic containers
  • Cold burns due to touching cold metal or direct contact with the liquid

These hazards can have fatal consequences, so it is important that all users of liquid cryogens make themselves aware of their local safety regulations. The OptistatDry does not use any liquid cryogens, so the hazards above do not apply to this product.

Costs of providing the facilities and safety training for liquid cryogens

The costs of running large liquefaction plant to provide an institute with liquid cryogens are high. These include the costs of running and maintaining the liquefier, and the costs of the fully trained staff to operate it.  

Less well documented are the costs and inconvenience of using liquid cryogens. Liquid cryogen storage dewars take up a large amount of floor space in the laboratory reducing the amount of space for experiments. Personal protection equipment and oxygen monitors are expensive and can be cumbersome. Ensuring everyone in the lab is trained and aware of all the relevant safety procedures can take up valuable time and limit the number of people who are able to work on these experiments. 

The OptistatDry does not use liquid cryogens so all of these costs and constraints no longer apply.
