Spectrometers

Micro-spectrophotometer can quickly and accurately detect nucleic acid, protein and cell solution and it has become a routine instrument in many laboratories.

Many advantages in using micro-spectrophotometer such as a clear and simple interface, allows the user to use less sample quantity during testing, no preheating necessary, quick and easy to clean after testing the sample, no cuvettes or other sample positioning devices required, samples do not need to be diluted.

During testing process, users can directly add the sample point to the sample plate. After the test the sample can be directly erased or recovered.
