Create as many freezers in the application as you have physical storage locations. Customize the storage layout, or hierarchy, within each digital freezer to match the physical storage options available to your users. This topic describes how to define a new freezer from scratch. Once you have created a freezer, you may copy it to create additional similar freezers.

Create a Freezer

When creating your first freezer, select Create a freezer under Storage on the main menu.

To create additional freezers, you'll click Create New Freezer from the Storage Dashboard or you may copy an existing freezer.

Freezer Properties

Under General Properties define the following:

  • Name: Any string name that will clearly identify the physical freezer; it must be unique in the system.
  • Description: Optional text description.
  • Manufacturer: Optional string for the company name or maker of this freezer.
  • Freezer Model: Optional string for the manufacturer-assigned model number or name.
  • Temperature: Optionally include the set-point or consistent operating temperature of this freezer when in use. When giving a temperature, specify Celsius or Fahrenheit.

Continue to define additional properties if needed and describe the structure of this freezer in the Freezer Hierarchy section before clicking Finish Creating Freezer. You can also return to edit this freezer after saving if you need to make changes to the properties later.

Advanced Freezer Settings

Click Advanced Settings to set the following properties for this freezer. Click Apply to save any changes.

  • Serial Number: Unique identifier for this unit that can be useful for troubleshooting with the manufacturer.
  • Sensor Name: If this freezer is using an alarm or monitor, you can provide the name here.
  • Loss Rate: Indicates the time needed or rate at which the unit will return to an ambient temperature from its set-point.
  • Status: Used to indicate if the unit is storing samples, available as a backup, or defrosting as part of a maintenance routine. Options:
    • Active
    • Backup
    • Defrosting

Freezer Hierarchy

Click the Freezer Hierarchy section to open it. Add the specific Storage Units available in your physical freezer to the panel on the right by dragging them to the proper location in the hierarchy.

There are two categories of storage unit available:

  • Non-Terminal Storage Units : These units can be contained within each other in any combination, but cannot directly contain samples. For example, a shelf can have a rack which has 2 shelves, but there must be a bag, box, or plate on those inner shelves to contain the samples themselves.
    • Shelf
    • Rack
    • Canister
  • Terminal Storage Units: These units can directly contain samples and cannot contain other units. Note that these units will only appear in the hierarchy interface when one or more types or sizes have been defined.
    • Bag
    • Box
    • Cane
    • Plate
    • Tube Rack

The system includes several built-in types (sizes/layouts), of each kind of terminal storage unit. You can customize the selections or add new ones by clicking Manage storage unit types. Note that your work in progress creating this freezer will be lost if you click away now. Consider saving your work and returning to edit the freezer definition when you have refined the options available.

Start with the "large" containment in your freezer, then drop structure within that container directly on top in the panel to place it "within" the container. For example, in this image there are three shelves, and to describe that one shelf has several racks, we drop the first rack directly "on" the shelf. If we put it "next to" the shelf, it would be added as a separate rack not associated with that shelf. Once a storage unit "contains" other units, you can directly drag new storage units "into" it.

Drag to add all the storage units that are used in your freezer, then drag and drop to rearrange them to match how they are physically arranged. Clicking the icon to clone a unit, adding another copy of it at the same hierarchical level (including any nested storage units it contains).

Use the icon to collapse the display of any nested units - it will become a you can use to expand the display again.

Continue to add the structures and terminal storage units that will contain your samples. For each terminal storage unit, you also specify the type (size/layout) of the unit.

  • Bag: Select bag type from the dropdown.
  • Box: Select box type from the dropdown.
  • Cane: Select cane type from the dropdown.
  • Plate: Select plate type from the dropdown.
  • Tube Rack: Select the type of tube rack from the dropdown.

Naming Units

By default, all the storage units you add will be named in a sequential numbering scheme, including the type of storage unit in this name. You can edit these names in any way will help your users find the correct locations, such as position/color/identifying labels you have applied. Unit names must be unique at any given level in the hierarchy. It is good practice to use unique names throughout the freezer to avoid confusion, particularly where there are many similar structures within your freezer.

Cloning

If you click , you can clone a unit that contains other nested units. The entire structure will be cloned at the same level as the parent. This can speed the process of describing a repetitive freezer hierarchy.

Finish Describing Hierarchy

Continue to add elements and rearrange them to describe your storage. Here, there are three shelves. One of the shelves has 2 bags, another shelf has two racks, each with 2 boxes of different sizes.

  • Once you have completed your storage hierarchy, click Finish Creating Freezer.
    • Note that you can return to edit your freezer hierarchy later, such as after defining new storage units.
    • If any storage names are duplicates within a given hierarchy, an error will be raised highlighting both of the matching names so that you can edit one or both to be unique. No error is raised for duplicate names in different parts of the hierarchy.
After saving, you will see the Overview page for your freezer. It summarizes the details, capacity, and will later show the contents. Learn more about the overview page in the topic: View Freezer Details

As long as you have included some terminal storage units such as bags or boxes, you will see a capacity and can now store samples in it. If not, you will see the message "This freezer has no terminal storage units configured", with a quick link to edit the freezer to add some.

Next Steps

Once you have added at least one freezer that includes some terminal storage locations, you can proceed to store samples in freezers.
