UV Crosslinker Bio-Link

UV Crosslinker

For Southern and Northern Blotting. Microprocessor controlled UV irradiation system.

Available in three different wavelengths (254 nm, 312 nm oder 365 nm)

Power 254 / 312 / 365 nm

Part Number: LTF00061


The emission of the UV light is constantly monitored by a UV sensor which is controlled by a microprocessor. The irradiation stops automatically when the energy received matches the energy programmed. The irradiation cycler are perfectly reproducible and are independent from intensity fluctuations of the UV source. Just programme the energy and Bio-Link delivers it!

UV exposure chamber in stainless steel, protective quartz disk on the UV sensor cell, highly resistant tactile membrane keypad. The readout display and the large number of presets, either in energy unit (Joules/cm²) or in time unit (seconds), makes the Bio-Link a very simple instrument to use while very powerful.
The UV light intensity is captured in a well of light above the irradiation chamber, so that the UV cell measure is collected from all the UV tubes and not just one. This also protect the UV cell from any dirt which can enter the chamber.
