Как оценить качество лабораторного стола?

The laboratory bench is the main equipment and furniture for our experiments, and its quality affects the accuracy of the experiment and the life of the lab bench. When we build a new laboratory, we need to choose high-quality equipment. When comparing different configurations, it is helpful to start from our standard modular lab table bench designs. So, how to judge the quality of the laboratory table?

Качество лабораторных столов можно оценивать по следующим аспектам:

1. Материал столешницы

The table top materials of the lab bench mainly include standard board, solid core physical and chemical board, and epoxy resin board. The 25mm standard plate is not resistant to high temperature, strong acid and alkali, and cannot be repaired after the surface is scratched, and it is easy to warp. This kind of countertop cannot be used in the chemical laboratory. Apart from the low price, it has no advantages. The 12.7mm solid core physical and chemical board can resist different degrees of strong acid and alkali, but the countertop will leave different degrees of flaws, it is not resistant to high temperatures (about 80 degrees), easy to deform, and cannot be repaired, and is now slowly being phased out. The 16mm epoxy resin laboratory countertop board is resistant to high temperature of 350 degrees, and there is no problem with the instantaneous temperature of 600 degrees. It is resistant to strong acids and alkalis and is not easy to denature. It is currently the most mainstream board type.

2. Тарелка

The boards of laboratory furniture are mainly melamine boards, but melamine boards are also divided into many types, with different brands, thicknesses, and colors. A good melamine board must be a national E1 board, and the formaldehyde does not exceed the standard. When you cut it, you can see that there is wood inside shaved, not a powdery substance. Moreover, the price of a good three-poly board can be twice of the worst three-poly board.

3. Стальная рама

The steel of the steel frame depends on the place of origin. It must be more than 1.2mm, the thicker the more reliable. The surface is polished, pickled, phosphated, and then sprayed with epoxy resin, which can effectively prevent acid, alkali, and rust. The epoxy resin spray is also thick and thin, so pay attention to careful observation. You can inspect similar heavy-duty frame welding standards in our steel lab furniture for research center project.

4. Ручка

Ручка может быть обычной ручкой из сплава, которая стоит несколько центов каждая, или пластиковой ручкой однообразной формы, которая стоит десятки долларов за метр, или ручкой из алюминиевого сплава с более высокой ценой.

5. Шарнир, направляющая

Hardware accessories account for a small proportion of laboratory furniture, but they are directly related to the quality and service life of the lab furniture. For all-metal benches, you can also consult our guide on how to inspect stainless steel table quality to review joint and sliding hardware specifications. Before purchasing, you must be familiar with related knowledge, or check relevant information online.

6. Лабораторные аксессуары

Laboratory accessories such as sinks, faucets, drip racks, eye washers, etc. also depend on the relevant brands, and try to choose products produced by large manufacturers with better quality.
