User Guide For Hand Press For Making KBr Pellets

Product Description

General overview of the hand press

The hand press is a tool used for making transparent KBr pellets (discs). It is designed to create pellets using only the pressure of a firm handshake applied steadily to the handle. The kit includes a die set for making 7mm diameter pellets.

Die sets made of hardened nickel-based alloy

The die sets used in the hand press are made of a hardened nickel-based alloy. This material ensures durability and longevity of the die sets, allowing for repeated use without compromising their quality.

Optically polished anvil faces

The anvil faces of the hand press are optically polished to a mirror finish. This polishing process ensures that the anvils are free from scratches or digs, resulting in high-quality pellets with smooth surfaces.

Optional 2 and 4mm die sets and collars

In addition to the standard 7mm die set, the hand press offers optional 2mm and 4mm die sets and collars. These additional options allow for the creation of pellets with different diameters, providing versatility and flexibility in pellet preparation.

The hand press is a versatile tool that allows for the convenient and precise creation of KBr pellets. With die sets made of hardened nickel-based alloy and optically polished anvil faces, this hand press ensures high-quality and consistent results. The optional 2mm and 4mm die sets and collars further enhance the versatility of the hand press, enabling the creation of pellets with different diameters to meet specific requirements. Whether used for research, analysis, or other applications, the hand press provides a reliable and efficient solution for pellet preparation.

KBr Pellet Making Technique

Pouring KBr powder/sample matrix into the SS collar

To make KBr pellets, start by pouring the KBr powder or sample matrix into the hole in the stainless steel collar. Make sure to use dry KBr powder and ensure that the anvils, die set, and powder are all at the same temperature. Heating the anvils and the body of the die set before making the pellet helps to remove any moisture. This step is crucial to ensure the formation of high-quality pellets.

Insertion of the longer second anvil and placement in the press handle

After pouring the KBr powder into the collar, insert the longer second anvil into the collar. Then, place the assembly in the press handle. The anvil supports the die in the KBr Pellet Press and can be raised or lowered to adjust the thickness of the pellets. The ability to adjust the anvil setting allows for the production of pellets of any desired thickness.

Applying pressure to the sample

To form the KBr pellet, apply pressure to the sample by squeezing the handle of the press. The press is equipped with a load knob that allows for the application of the required load for sample preparation. The pressure applied should be sufficient to form a compact and uniform pellet.

Removing the anvils and retention of KBr pellet inside the collar

Once the desired pressure has been applied, remove the anvils from the collar. The KBr pellet will be retained inside the collar. The pellet should be solid and well-formed, indicating successful pellet formation.

Placement of the collar in the optional V-shaped sample holder for analysis

After the pellet has been formed, place the collar containing the pellet in the optional V-shaped sample holder. This sample holder is designed to fit a standard 2 × 3-inch slide mount of any spectrometer. The V-shaped holder allows for easy positioning and analysis of the KBr pellet.

Rinsing or ejection of the pellet post-analysis

After the analysis is complete, the pellet can be rinsed out of the collar with water or ejected and saved for future reference. Rinsing the pellet helps to remove any residue or contaminants that may have accumulated during the analysis. Alternatively, the pellet can be saved for further analysis or reference.

The KBr Pellet Making Technique provides a simple and effective method for preparing high-quality KBr pellets for spectrographic analysis. By following the proper procedure and ensuring the use of dry KBr powder, reproducible and reliable results can be obtained. The KBr Pellet Press is a compact and hand-operated device that offers a convenient and economical solution for laboratories engaged in various scientific operations.
