Special precision tool, surface cleaned and clean-packed in a class 100 environment.
[Features]
· Excellent acid resistance and long service life.
· Entirely non-magnetic and suitable for electronic components.
· Has a ridged handle and slip prevention for better usability.
· Made of chrome steel.
[Applications]
· For moving and picking up things that are difficult for ordinary tweezers to handle.
· Also ideal for picking up or transferring thin and fragile objects such as semiconductor wafers, mica, etc.
Nonmagnetic Long-Life Tweezers Utilizing A Non-Slip Treatment On the Handle Portion
Even objects that are otherwise difficult to grasp with ordinary tweezers and thin easy-to-break objects can be grasped easily.

About The LPC Measurement Of This Product
The purpose of the evaluation is to measure residual particles after washing.
Evaluation Method
- 1.Sample pure water into a beaker, and perform LPC measurement (BG value).
- 2.Load the beaker into the product being measured, and perform LPC measurement (actual measured value).
- 3.Subtract the BG value from the actual measured value to get the determination value.
Measurement Conditions
- 1.For the amount of water to measure, use 10 cc 3 times and take the average value.
- 2.The measurement site conditions must be a Class 100 cleanroom.
Equipment Used In The Evaluation
- 1.In-Liquid Particle: KE-11A1 (Rion)
- 2.Syringe Sampler: KZ-30W (Rion)
- 3.Light-Scattering In-Liquid Particle Detector: KS-42B (Rion)
- 4.3,000-cc beaker × 1 (for BG water sampling)
