Vito is the earliest semi-automatic biochemical analyzer manufacturer in the world. It used to manufacture biochemical analyzers for companies such as Beckman and Merck.
ISP, vitallab2 1, Micro95, Micro98 and microlab300 were first introduced into China in the afternoon of 1985. At present, it is a China version of Microlab300 semi-automatic biochemical analyzer, with more than 1 10,000 domestic users and 65,438+10,000 global users.
The reason why it has become the leader and leader of the semi-automatic biochemical instrument market and has such a large market share is because it has the following advantages that other instruments do not have. Some of these advantages are controlled by patents, and some are determined by costs, which cannot be achieved by other semi-automatic biochemical instruments.
1. The colorimetric cell is designed as vortex turbulence, and the liquid is washed in and out at an angle of 60 degrees, which can achieve the special effect of reducing pollution and eliminating bubbles, with 400uL cross-contamination.
Second, the vacuum capsule pump (compared with Lusi pump) can keep the liquid absorption speed 10 times higher than the number of peristaltic pumps, and the control accuracy reaches luL.
The advantages of one step in place and long service life are incomparable to other peristaltic pump instruments.
Thirdly, the rapid monitoring and reference analysis of 40 test points per second in the actual measurement process make the anti-interference and accuracy perfect.
Fourthly, stabilizing the high-precision ultraviolet detector can improve the detection efficiency of ultraviolet wavelength and make the kinetic method more accurate and stable.
5. The unique programmable reference amplification system not only improves the measurement accuracy, but also ensures the stability and high reliability of the instrument, and the zero drift is L hours.
Six, the overall control and key components are European military-grade products, and the failure of the instrument is incomparable to other instruments. ISP biochemical instrument has been used in China for 17 years, and many users are still using it.

12. test methods: dynamic method (including linear test and slope blank test), two-point method (including test blank and excluding test blank), end-point method (including sample blank and test blank) and dual-wavelength method.
13. Repeated test: 9 repeated tests can be selected at most, and the mean value, standard deviation and coefficient of variation can be calculated.
14. experimental parameter setting: instrument display, and manually fill in data according to prompts, including experimental name, measurement mode, first/second wavelength, inhalation amount, delay time, measurement time, factor, standard concentration, actual blank (y/n), sample blank (y/n), result unit, normal reference range and curve fitting (.
15. Delay time: 0-999 seconds is optional, which is sufficient.
16. Measurement time: 2-998 seconds for dynamic method and two-point method, and 2 seconds for end-point method, which is sufficient.
17. Calibration point: Factor method, one-point calibration, two-point calibration and multi-point calibration have at most 10 point standard, which can be used for linear test and nonlinear test, and turbidity method can also be applied.
18. quality control: each experiment can bring two kinds of quality control substances, analyze and evaluate 30 quality control points, print or display Levey-Jennings quality control chart, and call the police when the upper and lower limits are out of control.
19. Flow colorimetric cell: 60-degree turbulent colorimetric cell with metal time window, patented product, measuring volume only needs 25ul.
20. Temperature control: Peltier element is adopted, and the temperature control accuracy is 37℃ 0.2℃.
2 1. Suction system: the stepper motor is equipped with a vacuum diaphragm pump, which has high speed and high precision, and has lu 1 step control between 250UL- 1.
