The  introduction as follows:

Laboratory test sieves of purchase notice:

Tip 1: the purpose of screening:

If you are purchasing for the laboratory, you must require exquisite appearance and practicality, accurate mesh, and have been tested by professional testing equipment, and meet the national standard GBT6003-1997 or the international standard ISO3310-1:1990 standard sieve.

If you are using the factory for internal testing (the product is not exported) you can purchase our sample sieve. The main difference between the standard sieve and the laboratory test sieve is whether the mesh is in compliance with national standards.

Tip 2:the points to be provided when purchasing:

1. What criteria are required to be met.

(Example: I need a standard laboratory test sieve that meets the national standard GBT6003-1997)

2. Provide mesh size and wire diameter.

The test sieve can be purchased according to the pore size and mesh number, and the experimental sieve used has a different pore diameter depending on the purpose.

3. What materials are tested.

Before screening the laboratory test sieves, the manufacturer will select the appropriate experimental sieve material and related configuration according to the characteristics of the material screened by the user. All the components of Dahan laboratory test sieves are made of high quality SUS304 stainless steel. The sieves above the test sieve 120# in the national standard are woven with copper. If you need stainless steel, please explain.

4.Square hole sieve or round sieve.

For cylindrical particles, the square hole sieve has better pass performance; and for irregular particles, the pass performance of the round hole sieve is better.

Tip 3:look for national standards:

As a kind of laboratory test sieves with the most stringent precision requirements in the screening equipment, the laboratory test sieves must be selected from the national standard when used for purchase. It is used for the vibrating screen under the national uniform specification. This is the factor that should be paid attention to when purchasing the laboratory test sieves. 

 

The above high-quality experiments should be paid attention to in the process of screening and purchasing. The Xinxiang Dahan laboratory test sieves are designed and produced according to the national standards. The quality of the laboratory test sieves are guaranteed and the performance is stable.
