What is the temperature range for the Polar Bear Plus?
-40°C to +150°C
-
Is the accessories list common to all of the instruments, the Cub and the Plus?
Yes
-
What temperature gradient is achievable with 2 ML standard HPLC vials (25°C to -40°C)?
About 1 °C/min. A graphic is shown in the Performance Section of the Polar Bear Microsite
-
What is temp gradient with 100 mL RBF (25°C to 0°C)?
55 minutes (i.e. 1°C/minute)
-
What is fastest and slowest gradients achievable?
This partly depends on the range. Typically 1°C/min and 0.01°C/min respectively
-
What are the fastest temperature Ramps?
With 4 x 4mL vials. 20°C to 80°C in 5 minutes = 12°C/minute
Holding Polar Bear Plus at -40°C, A temperature crash of about 6°C/min is achievable -
What is slowest temp Ramp?
Temperature ramp of 0.01°C /minute
-
For how long will the Polar Bear hold vials at a given temperature?
Indefinitely or until the set point temperature is changed
-
What happens if the Polar Bear exceeds -40°C or +150°C?
The cooling device will not cool beyond -40°C. The heater temperature is limited to an upper limit of 170°C.
-
Can liquid penetrate electronics?
Unlikely. The top plate is sealed to prevent liquid access.
-
What is the external temperature sensor?
The external temperature sensor is a PT100 resistance thermometer.
-
What size do I need?
You need one 50mm long when working with our vial holders. 300mm long when working with RBFs.
-
Is a PT100 thermocouple supplied with a Polar Bear?
No.
-
Can I have both magnetic and Overhead mechanical stirring?
Each unit may be configured for either overhead or magnetic stirring. However, with the addition of the compatible Smart controller both magnetic and overhead stirring can be achieved from a single Polar Bear Plus.
-
Can I operate the Polar Bear remotely?
Yes
Connect to the Polar Bear Plus using the Ethernet connection or through your Local Area Network. -
