Filtech Testing Division - Vibration Test

Ensuring a Steady Workspace

At Filtech, our Vibration Test is an optional evaluation available upon request to determine the amount of vibration in your biosafety cabinet. We understand the importance of a stable workspace, and our test ensures your cabinet meets the required standards.

Test Purpose

The Vibration Test serves the following purpose:

Determines the amount of vibration in the operating cabinet.
Ensures the cabinet operates within the specified tolerances of ±3 ft/min (± 0.015 m/s) of the nominal set point velocities.

Apparatus Used

We employ advanced equipment for the Vibration Test:

Vibration analyzer with an accuracy of 5% of full scale.
Minimum reliable reading of 1 x 10-4 inch (2.5 x 10-6 m) RMS amplitude or the ability to detect differences of this magnitude.
Capable of measuring vibration in displacement mode within the 10 to 1,000 Hz frequency range.

Test Method

Our expert technicians perform the Vibration Test with precision:

Affix the sensing element of the vibration pickup unit firmly onto the geometric center of the work surface(s) using appropriate methods such as clamping, bolting, integral magnet with petroleum jelly film, or double-faced adhesive tape.
Determine the gross vibration amplitude with the cabinet operating.
Determine the background vibration amplitude with the cabinet blower(s) off and, if applicable, the exhaust blower on.
Subtract the background from the gross vibration amplitude to determine the net vibration amplitude attributable to the cabinet.

Acceptance Criteria

We adhere to strict standards to ensure a steady workspace:

Net displacement shall not exceed 2 x 10-4 inch (5 µm) RMS amplitude at frequencies ranging from 10 to 1,000 Hz in the center of the work surface(s).
