1. General requirements

1.1 The spraying of cleaning water and the dissolution and stripping of cleaning solution can assist in cleaning the inorganic residues (such as lead, mercury, cadmium, arsenic, etc.) and organic residues (such as industrial dyes, hormones, grease, dust, etc.) of laboratory glassware or plastics.

1.2 The organic residue after cleaning is less than 0.1mg/L, and the metal ion residue is less than 0.02mg/L. The provincial authoritative experimental report or certification on the cleaning effect must be provided. In order to ensure the accuracy of the experimental results of trace analysis, the equipment has passed ISO9001, CE and other relevant international authoritative certifications.

1.3 The power supply voltage is 220V.

2. Structural design

2.1 Double-layer detachable heat insulation and sound insulation shell, the inner cavity is made of 316L stainless steel, and the outer shell is made of 304 stainless steel.There are no exposed screws and rivets on the outside.

2.2 The height of the equipment is 110cm, which can be embedded in the test bench, the length and width are less than 75cm, and it occupies a small area.

2.3 There are two layers of cleaning racks in the cleaning cabin, which can clean 420 liquid phase autosampler vials or test tubes, colorimetric tubes or 72 volumetric flasks, beakers, conical flasks, etc. at a time.

2.4 Internal foaming double-layer metal door is adopted to effectively insulate and reduce energy consumption.

2.5 It has two water inlets, which can be connected to tap water and pure water at the same time, and which water needs to be entered can be selected through the operation of the control panel.

3. Control system

3.1 Microcomputer control system and color LCD screen are adopted. The tilt angle design of the operation screen conforms to the principle of ergonomics. It is easy to operate and has better user experience.

3.2 The control screen has a full Chinese operation interface, and both operations and alarms are prompted in Chinese.

3.3 The control system has 12 standard cleaning procedures and 99 custom cleaning procedures, which can be set and adjusted for different utensils and requirements.

3.4 “Black box” function, built-in data memory, the whole process of recording the cleaning status of each step, the system has self-diagnosis function, fault information prompt function;

4. Cleaning system

4.1 The cleaning water pump is a professional European original imported circulating pump. Its water output is 800L/min, the water output is large, and the scouring force is large. The circulating pump fan blades have been treated with high temperature resistance and can work normally under the disinfection water temperature (above 93 ℃).

4.2  The cleaning cabin adopts the water supply structure of parallel water supply and water inlet at the back, instead of the structure of water inlet at the top and one-way water supply at the center. Water inlet from the side, and there is no need to find the water receiving port, convenient access, and the joint is not easy to be damaged.

4.3 The cleaning rack adopts the structure of water inlet in the back and water distribution in the central part. The central part divides water, and the cleaning rack connects the water to the middle part and distributes the water evenly to each spray column to ensure that each spray column discharges water evenly and cleans the utensils uniformly.

4.4 The spray columns of the cleaning rack shall be distributed in parallel rather than around the center, so as to ensure the consistent distance between each spray column and facilitate the placement and estimation of utensils while increasing the cleaning amount.

4.5 The cleaning rack does not have a tall central water inlet pipe, which saves space and is convenient to place; the upper and lower floors of the cleaning rack can be interchanged to facilitate the arrangement of utensils.

4.6 The cleaning cabin has a built-in double-layer 360-degree rotating spray arm, and the nozzle adopts a fan-shaped nozzle design, which sprays a fan-shaped water curtain with large scouring force and no dead ends. No simple small hole nozzle is used to reduce the dead angle of external spraying.

4.7 The glassware washer adopts an automatic heating system during cleaning, and the heating temperature is adjustable. The maximum temperature can reach 93°C, reaching the disinfection level.

4.8 The cleaning solution and neutralization solution are automatically added by two peristaltic pumps, and the added dosage can be set.

5. Safety protection

5.1 Safe door lock design, the door body is locked and cannot be opened during the cleaning process, preventing water spraying and scalding caused by misoperation; It has the function of emergency door opening, which can quickly open the door and take out the utensils after power failure.

5.2 It has a complete protection function, with a lack of cleaning agent alarm, the main washing pump over-temperature protection function, heating and anti-dry function, the main washing pump idling protection function, water level sensor detection function, cleaning chamber over-temperature protection function, all have Chinese prompt and alarm reminder.

5.3 It has the function of program self-checking and equipment self-cleaning, which can perform self-checking on the set program. After cleaning, the equipment can also be automatically cleaned to reduce residues.
