SYJ-T01 TEM Sample Sampling Machine: Precise Preparation of Burr-Free Circular Samples

Difficult sample preparation for transmission electron microscopy (TEM)? Easily deformed sample edges?

The Shenyang Kejing SYJ-T01 TEM sample sampling machine is specifically designed for preparing ductile metal and alloy thin sheets with a thickness ≤50μm. It allows for precise manual punching of standard φ3mm samples, resulting in burr-free and indentation-free edges. Compact in size and with customizable molds, it is an essential piece of equipment for high-quality TEM sample preparation in the laboratory.

In materials science, the TEM sample sampling machine is an indispensable top-level observation tool. However, "three parts observation, seven parts sample preparation"—preparing a qualified TEM sample is often extremely tedious. Obtaining a standard circular sample from thin film materials is the most basic yet error-prone step—even tiny edge burrs or punching deformation can severely affect subsequent thinning processes and the final imaging quality.

To address this, Shenyang Kejing specifically developed the SYJ-T01 TEM sample sampling machine. This fully manually controlled precision desktop instrument, with its extremely high punching accuracy, has become standard equipment in many electron microscopy laboratories.

Why do TEM labs need a SYJ-T01?

The SYJ-T01's design eliminates complex and redundant structures, focusing entirely on "punching quality" and "operational experience."

1. Punching Quality: Burr-free, Indentation-free.

The upper and lower dies are precisely machined and fitted. It can easily handle thin sheets of metals, alloys, and various tough materials with a thickness ≤50μm. The punched Φ3mm round sheets are precisely sized with smooth edges, truly achieving burr-free, indentation-free, and perfectly protecting the original microstructure of the material (customizable, selectable sizes from φ3 mm to φ24 mm).

2. Automated Retraction and Sample Collection.

The SYJ-T01 sampling device also boasts many details in terms of operational experience. The punch head features a unique elastic clamp design, automatically springing back after the user completes the punching action, saving time and effort. Simultaneously, the punched standard sample falls directly into a dedicated sample box at the bottom, completely eliminating the risk of losing small samples on the lab bench.

3. Compact Size, Customizable Dimensions.

Weighing only 10kg, the machine is compact (200×120×280 mm), taking up minimal valuable lab bench space. While the standard configuration includes two sets of Φ3mm dies, Shenyang Kejing offers flexible customization services, customizing punching dies with diameters ranging from Φ3mm to Φ24mm to meet specific experimental needs.

Professional Maintenance Recommendations for Extending Die Life (H2) As a high-precision mechanical stamping device, proper operation and maintenance are crucial for ensuring sampling quality: Precise Alignment: Never attempt to use the machine if the punch and punch hole are not properly aligned. When adjusting the die, ensure the upper die core enters the lower die smoothly and unobstructed to protect the extremely delicate cutting surface.

Daily Cleaning: After each use, wipe the die and all parts of the machine body clean with a clean cloth dampened with alcohol.

Rust Prevention: If the machine will not be used for the next day, it is strongly recommended to apply rust-preventive oil to the die and exposed metal parts to prevent oxidation from affecting cutting accuracy.
