This instrument adopts microcomputer measurement and control, fully digital circuit, high-precision temperature sensor and unique water bath constant temperature system. It is easy to operate, reliable in performance and accurate in data. Its technical indicators fully meet the relevant standards of the national pharmaceutical industry. It is the best instrument for pharmaceutical factories, schools, research institutions and cosmetics industry to test transdermal drug release rate.
I. Functional Features & YJ-6000 Transdermal Diffusion Apparatus
The transdermal diffusion apparatus consists of three parts: temperature control, motor speed control and time control. When the instrument is turned on, the temperature display shows the actual ambient temperature, the motor speed displays 350 (350 revolutions per minute), and the time displays 00:00 (hour:minute)
II. Technical Parameters:
(1) Number of transdermal cups: 6 units
(2) Volume of receiving chamber: 15ml
(3) Temperature control range: Room temperature — 40℃
(4) Temperature control accuracy: ±0.1℃
(5) Stirring speed adjustment range: 100—800r.p.m
(6) Speed accuracy: ±5%
(7) Power supply and power: 220V±10% 50HZ 360W
III. Working Principle of Vertical Transdermal Diffusion Cell (Standard Configuration): Place the skin between the supply chamber and the diffusion chamber, with the lower part of the skin immersed in the solution, and clamp the upper and lower parts of the diffusion cell with clips. The drug is put in from the upper part and gradually penetrates through the skin into the lower diffusion chamber. The outside is insulated with constant temperature water, and the stirring bar stirs at a constant speed to keep the solution at an isothermal state and the concentration of the permeate uniform. The supply chamber is exposed to air to allow the skin to conduct experiments at room temperature.
IV. Working Principle of Horizontal Diffusion Cell (Optional Accessory)
Place the skin between two horizontal cells, put it into a white fixture, insert a pressure relief sheet between the top screw and the bottom of the bottle, and then tighten it.
During the experiment, administer the drug from one side to allow it to penetrate to the other side. The outside is insulated with constant temperature water, and the stirring bar stirs at a constant speed to keep the solution at a uniform concentration and constant temperature. This device can effectively prevent the generation of air bubbles.
V. Precautions:
(1) Do not put corrosive solutions in the water tank. Regularly check for leaks in the water tank and clean scale in time.
(2) It is strictly prohibited to heat without water. The water level in the water tank must at least exceed the heater.
(3) If any of the six stirring magnetic heads stops rotating after long-term use, drain the water, invert the instrument and open the bottom cover for inspection. If the transmission belt is detached or broken, replace it with the spare transmission belt provided with the instrument.
(4) When the instrument is not in use, drain the water and disconnect the power supply.
