When it comes to analyzing samples in the lab, tools are needed for finely grinding and pulverizing them. When we talk about the tools used for this purpose, one has to mention agate mortar. This makes the agate mortar a preferred choice for sample preparation across many laboratory areas, as it has distinct benefits over other types of mortars such as glass or porcelain.
Agate Ball Mill Grinder Balls The SPI Supplies brand agate grinding balls are designed for use in all ball mills for the fine grinding, without contamination, of minerals, plastics + More Agate Grinding Mills - Capital Scientific Their hard and antibacterial nature makes them perfect for this use. Agate mortars, widely used for grinding small amounts of grains into fine powders (50 mm diameter: No. 80): • Agate mortar refers to a cylindrical vessel made with the mineral agata and typically paired with a pestle—a longer rod-segment instrument that helps grind samples into an extremely fine powder as shown in Figure-II exhibits various sizes reaching up-to 100 x150mm diameters than Mortar & Pestles used In Common laboratories.
In your sample preparation using agate mortars, following the below given tricks and tips can greatly increase efficiency of the process resulting in better results. These recommendations include:
Choose the suitable size of agate mortar: choosing a too small one will hinder grinding and cause sample to stick on wall Conversely, opting for a mortar too large will mean both wasted time and poor results.
A small number of abrasives: In the sample introduces a very few abrasive materials into samples accelerate grinding, reduce contamination.
Samplepre grinding:If your sample is very hard or must be ground by a significant amount of force in an agate mortar. The grinding process can be accelerated when the optimal tool, a jaw crusher sees pre-processing and makes such kinds of samples ready for efficient grinding.
Cleaning the mortar completely: The cleanliness of the mortar is very important to avoid contamination of other samples, so a thorough cleaning after use should be done. The best method of cleaning is to wash the mortar well with water and turn on in an oven at temperatures of 110-120 ° C for not less than two hours.

BackAgate Mortar and Pestle Set, 150 mm Diameter: Perfect for pulverizing larger amounts due to this set includes a mortar with a corresponding pestle. The contrastingly beautiful bookend is made from top-grade agate and constructed for use in even the most demanding lab settings.
Agate Mortar & Pestle Set, 200 mm Diameter Heavy-duty laboratory grade agate mortar and pestle set for largest scale of grinding applications. It comes with a closely compatible pestle for the 200 mm diameter mortar made of high quality agate.

In a laboratory setting, the nature of the sample being ground and its size are type determining factors for choosing best mortar. Use Firstly Agate mortars are usually used for hardest and most brittle materials; glass or porcelain aextensivelye employed tforfer samples.
Also, the sample size determine which kind of mortar you needed. The small samples called for the smaller mortars, while the large samples demanded that we use larger said-mortars. Therefore, the relevance regarding choosing best and correct dagger dimensions becomes very important in identifying grinding results.

Agate mortars and pestles operate on the simple principle of compression grinding. Once the sample is placed in the mortar, it is crushed and ground against the walls of a mortar (see Fig.. 2) by means of a pestle. Grinding involves the application of mechanical force to particles in some other ways, better product can be achieved by more than one grinding.
The toughness and durability of agate make it perfect for crushing hard, brittle samples including rocks and minerals. The use of agate mortars for sample preparation in laboratory analyses has a long track-record, and with good reason as it is the most adequate method to prepare samples.
To sum up, using agate mortars for sample preparation in laboratories would offer plenty of advantages that improve productivity as well as reduce the risks for contamination and ambiguities. You can understand from above case that, you need to be very particular during Agate mortar selection & any improper choice of size in Mortar and pestle with the sample size may easily crush it. In addition, and this is another downside but also a grip-up of the compound, to keep the mortar pestle in great condition after use requires very thorough cleaning.
