Enclosed circulation system at ambient temperature
For those who prefer a more refined, closed system, upgrade to the KOOL 440. The KOOL 440 consists of a Koolance EXT-440CU (with the blue led of the reservoir disconnected), the NZL-V06B barb for ID 06mm, 2 ¼ to ⅛ tubing adapters and a length of 1/8-inch diameter tubing. The TC-1 adapter cable provides 12 Volts DC to the Koolance circulator. Use to control your cuvette holder in the range of 0. to 100 degrees Celsius. The KOOL 440 consists of a reservoir, a pump and a heat exchanger and will maintain the circulating fluid at temperatures just above ambient.
