Selection Guide for Laboratory washer

1、 How to select a manufacturer? (The following requests need to be referred to)
Manufacturer qualifications: 1. ISO9001 quality system, ISO14001 environmental system;
Instrument quality: A professional manufacturer of cleaning mechanisms in the laboratory cleaning industry, with widespread use and good reputation in the user's location or industry;
Product certification: 2. EU CE certification, EN ISO 15883 specification;
Technical service: 3. Our own after-sales service team, with after-sales service engineers stationed nationwide; The normal delivery time is one month, and the accessory delivery time is within two weeks;
2、 How to ensure functional durability, can the following functions be achieved?
Function: 1. Stable water supply, ensuring different water pressure and cleaning cleanliness for the same batch;
2. Variable frequency soft start function, pump variable frequency setting, reducing damage caused by sudden water pressure impact;
3. Controlled by microcomputer chips instead of low-end PLCs (elevator control has been phased out and unstable);
4. Integrated machine, without the need for external water heating installation, with a non perforated chamber connected to the laboratory for draining steam;
3、 How to choose instrument specifications?
Cleaning chamber volume: The cleaning chamber volume determines the number of containers to be cleaned in a single operation, as well as the specifications of the instrument;
Control method: The integrated full-color LCD touch screen is superior to the knob button type. Note: Handheld full-color touch screen control terminals on the market have poor applicability and use data cable connections, making operation inconvenient (they are only additional optional accessories added to respond to high-end machine configurations, and their applicability is not significant);Laboratory bottle washing machine

Instrument control: parameters such as cleaning temperature, time, water source, drying (temperature, time), rinsing, etc. can be set freely. What is the number of programs, and whether the program can be called (PLC control has calls). The full-color touch screen method is generally superior, and all parameters of the LCD screen can be freely set, with multiple programs to meet different cleaning needs;
Note: In terms of the number of cleaning layers, the upper and lower layers of the configuration above double layers should simultaneously meet the cleaning requirements for 10-250ml volumetric bottles and 1L sampling bottles. Both upper and lower end machines can be equipped with double-layer or three-layer cleaning racks. Although the number of cleaning layers may be the same for upper and lower end machines, due to the space problem of their cleaning compartments, cleaning size and quantity, low-end machines can only clean small-sized vessels and a small amount of vessels with the same or more layers, resulting in poor cleaning applicability. Should not be misled by sales personnel's biased cleaning layers;
4、 Can it be washed clean?
Word of mouth: 1. Users use word-of-mouth to achieve cleaning effects in the same industry.
Report: 2. Provide a third-party cleaning residue verification report; Research on TOC and conductivity cleaning.
