Description
Product Overview
The Lichen Aluminum Cooling Block is engineered to meet the demanding needs of modern molecular biology laboratories. Constructed from high‑conductivity aluminum, the block rapidly transfers heat away from PCR tubes, ensuring that reaction mixtures remain at the optimal low temperature throughout the procedure. The surface is treated with a durable oxygen‑rich coating that resists abrasion and maintains a sleek appearance even after repeated use. The block includes a silicone rubber cover that fits snugly over the wells, providing an additional layer of insulation and preventing accidental spills.
Designed with versatility in mind, the cooler offers two distinct well configurations: 24 wells sized for standard 1.5 ml and 2 ml PCR tubes, and an additional 36 wells tailored for 0.2 ml micro‑tubes. This dual‑well system allows researchers to process a wide range of sample volumes without needing multiple devices. The wells are spaced to keep tubes from touching each other, reducing the risk of cross‑contamination and ensuring that each tube can be accessed independently.
Usage
In routine PCR workflows, maintaining a low temperature for reagents such as DNA polymerases, primers, and nucleotides is critical to prevent degradation. The Aluminum Cooling Block fits seamlessly into standard laboratory benches, incubators, or even portable cold‑room setups. Users simply place the block in a pre‑cooled environment (e.g., a -20 °C freezer) for a few minutes, then transfer it to the working area where it retains its chill for up to 30 minutes at room temperature, even at 30 °C ambient conditions.
Beyond PCR, the cooler is equally effective for enzyme assays, protein crystallization setups, and any protocol that benefits from a stable, low‑temperature platform. Its compact dimensions (6.73 × 5.04 × 1.54 in) and lightweight design (1.68 lb) make it easy to transport between workstations, field sites, or teaching labs. The silicone cover can be removed for quick cleaning, and the aluminum body can be wiped with a mild detergent without compromising performance.

FAQ
How long does the block stay cold after removal from a freezer?
When pre‑chilled at –20 °C, the block can retain a usable temperature range for approximately 30 minutes at room temperature (up to 30 °C), which is sufficient for most PCR setup procedures.
Can the silicone cover be sterilized?
Yes, the silicone cover can be autoclaved at 121 °C for up to 15 minutes without loss of elasticity or sealing performance.
Is the block compatible with standard PCR thermocyclers?
The block is intended for pre‑cooling and holding tubes; it is not designed to be placed inside a thermocycler. However, it can be used alongside any standard thermocycler for reagent preparation.
What is the recommended cleaning method?
Wipe the aluminum surface with a soft cloth dampened with mild detergent, then rinse with distilled water and dry. Avoid abrasive cleaners that could damage the protective coating.
Do you offer replacement silicone covers?
Yes, replacement silicone covers are available as part of our spare‑parts catalog and can be ordered directly through our support portal.
