Introduction To Laboratory Testing Equipment

Cleanroom Wipes are subject to rigorous testing to meet performance requirements and contamination control standards, generally cleanroom wipes are subject to the following tests:

(1)IC test

Measurement of inorganic anion and cation content according to specific units.

According to the regulations, the quantitative analysis is determined to accurately measure the inorganic anion and cation composition.

Referring to the test specification, in the tape machine manufacturing industry, it is generally stipulated that CL-≤0.03ug/c㎡; SO42-≤0.03ug/c㎡; NO3-≤0.03ugc㎡; Total:<1.0ug/c㎡

(2)NVR test

Non-volatile residues tested per unit area.

The NVR test is performed by soaking a dust-free cloth in a certain amount of organic solvent for a certain amount of time, then removing the cloth and testing the quality of the non-volatile residue in the dissolved organic solvent.

Referring to the test specification: In the tape machine manufacturing industry, the general rule is <3.0ug/c㎡.

(3) LPC test

Test for the number of liquid fine particles per unit area.

According to IEST-RP-CC004.3 Section VI.2.1, the LPC test is carried out on the dust-free cloth and the number of liquid fine particles on the dust-free cloth.

Referring to the test specification: in the tape machine manufacturing industry, the general rule is <30 counts/c㎡.

(4) FTIR test

Test the composition of dust-free cloths, mainly to identify silicone oils, amino digests, plasticizers, etc.

F707 Foam Swab is an excellent swab for cleaning surfaces. The head material construction, which is completely thermally bonded makes it adhesive-free.

Since this swab is processed in cleanroom, it is generally cleaner having low levels of contamination (Ionics and NVR).

Features:

Cleanroom-processed hence with low level of Ions and NVR (non-volatile residues)

a. Excellent chemical resistance but compatible with many solutions

b. Readily absorbs liquids and grabs particulates

c. Rigid head paddle and long, easy grip handle

d. Autoclavable in dry heat and steam

Application:

a. Cleaning with compatible solutions and solvents

b. Applying and removing lubricants and other liquids in a critical clean environment

c. Cleaning of recessed areas and picking up of fine powdered materials

d. Good for use with temperatures less than 350'F
