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. It meets the standard of GB T 27818-2021 "Chemicals - Skin Absorption - In Vitro Test Method", and is an excellent instrument for testing transdermal release rate in pharmaceutical factories, schools, scientific research institutions and cosmetics industry.
I. YJZ-6000 Drug Transdermal Diffusion Tester Functional Features:
The transdermal diffusion tester consists of three parts: temperature control, motor speed control and time control. When the instrument is turned on, the temperature displays the actual ambient temperature, the motor speed displays 350 (350 rpm), and the time displays 00:00 (hour: minute).
II. YJZ-6000 Drug Transdermal Diffusion Tester Technical Parameters:
(1) Number of diffusion cells: 6 (vertical type)
(2) Receiver volume: 15ml (other options include 17ml, 10ml, 7ml and horizontal type 5ml)
(3) Temperature control range: Room temperature — 40℃ (4-10℃ when external refrigeration device is optional)
(4) Temperature control accuracy: ±0.3℃
(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, immerse the lower part of the skin 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 isothermal and the concentration of the permeate uniform. The supply chamber is exposed to the air, so that the skin is at room temperature for the experiment.
IV. Working Principle of Horizontal Diffusion Cell (Optional Accessory)
Place the skin between two horizontal cells, put it into the white fixture, place a pressure reducing plate between the top wire and the bottom of the bottle, and then tighten it.
During the experiment, the drug is administered from one side to make it 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 concentration uniform and constant temperature. This device can effectively prevent the generation of bubbles.
V. Notes:
(1) Do not put corrosive solutions in the water tank, check regularly for leaks in the water tank, and clean scale in time.
(2) It is strictly forbidden to heat without water, and the water level in the water tank must at least exceed the heater.
(3) If six stirring magnetic heads do not rotate during long-term use, please drain the water, invert the instrument, open the bottom cover and check. If the transmission belt is detached or broken, please replace it with the spare transmission belt provided with the instrument.
(4) When the instrument is not in use, please drain the water and disconnect the power supply.
