Frequently Asked Questions
How long does the rack stay cold at 4°C?
After freezing per the manufacturer instructions, the gel core sustains a 4°C working environment for several hours of bench work. The color indicator shifts from green to yellow as it warms, signaling when to re-freeze.
Does it fit both PCR plates and strip tubes?
Yes. The 96-well layout accepts standard PCR plates as well as 8-tube strips, allowing flexible handling of multiple formats in a single rack.
How do I prepare the rack before use?
Place the rack in a -20°C freezer until the indicator reads fully green. It is then ready for benchside use; no ice or external coolant is required.
What does the color change indicate?
Green confirms the rack is at proper cold working temperature, while a transition to yellow shows it is warming and should be returned to the freezer to maintain 4°C performance.
