introduction：sz03-ii uv cross-linker is a multi-purpose 254nm uv radiation system, mainly used for cross-linking and fixing nucleic acids on the membrane.
product description:
sz03-ii uv cross-linker is a multi-purpose 254nm uv radiation system, mainly used for cross-linking and fixing nucleic acids on the membrane. it can also be used for dna cutting in agarose gel, reca mutation screening, partial restriction endonuclease digestion of pyrimidine dimer, uv sterilization to eliminate pcr pollution, etc. it also has application value in uv sterilization and polymer uv treatment.
features:
①in order to fix the nucleotides on the hybrid membrane, the traditional method is to bake the membrane in a vacuum oven at 80°c for 2 hours, and the uv crosslinker only needs to irradiate it under 254nm ultraviolet light for a few seconds.
②ultraviolet irradiation can increase the hybridization signal by 5-10 times compared with the traditional baking method.
③because the uv crosslinker is equipped with a uv energy programming system (joules/cm2), that is, the time integrator continuously detects the irradiation of uv light. when the energy absorption value reaches the set value, the irradiation will automatically stop. therefore, regardless of the intensity of the ultraviolet light source and the time difference, the irradiation cycle has good repeatability.
④the shutdown information is not lost, and the chinese lcd screen displays.
⑤the keyboard can be touched, and the window is blocked by uv.
⑥stainless steel uv exposure room.
⑦drawer-type ultraviolet irradiation system, convenient for users to operate, ultraviolet safety window and safety door lock design, can protect the safety of use.
can be irradiated area (88 cm2) and energy can reach 120mj/cm2, fast and efficient experiment.
