KOLAMOON Agate Mortar And Pestle Set, 50mm Lab Style
Made from high quality natural Brazilian agate, this set emphasizes pressure and heat resistance along with chemical stability. Its hardness range of 7.0–7.2 on the Mohs scale supports durable grinding of dense samples. The internal diameter is 50 mm (1.97″), with an external diameter of 62 mm (2.4″) and an inner depth of 15 mm (0.6″). Full-volume capacity is about 15 ml when filled with water. Suitable for lab grinding, labware, and standard-form mortars and pestles, it provides a reliable, non-porous surface for consistent sample preparation.
LAB4US Agate Mortar And Pestle Set, 80mm Natural Agate
This octagonal mortar is crafted from naturally hard agate stone, designed for grinding a matrix of solid samples in preparation for infrared analysis. Pure agate is non-absorbing in infrared spectrophotometry, reducing background interference. Key dimensions include an internal diameter of 80 mm (3.15″), external diameter of 100 mm (3.94″), inner depth of 24 mm (0.94″), and overall height of 34 mm (1.34”). The pestle measures 12 x 20 x 75 mm, with a tolerance of ±3 mm. Aimed at lab use, the specimen favors precise, repeatable grinding with minimal sample loss.
LAB4US Agate Mortar And Pestle Set, 50mm Grey
This compact 50 mm agate mortar and pestle emphasizes precision grinding with a 2″ (50 mm) internal diameter and a 60 mm external diameter. Its inner depth is 12 mm, and overall height is 24 mm. The octagonal form leverages the natural hardness of Brazilian agate to deliver consistent particle sizes, while the non-absorbing surface minimizes infrared interference during spectroscopic analysis. The product is well-suited to lab grinding tasks where space is at a premium and repeatable results matter.
KOLAMOON Agate Mortar And Pestle Set, 70mm Lab Size
This 70 mm agate mortar and pestle is built from high-quality natural Brazilian agate, offering strong pressure and heat resistance along with chemical durability. Its internal diameter is 70 mm (2.75″), external diameter 82 mm (3.22″), and inner depth 20 mm (0.78″). The full-volume water capacity is around 30 ml. It is designed for lab grinding tasks requiring a larger grinding surface while maintaining the non-porous, non-absorbing properties of agate for clean sample prep and minimal cross-contamination.
United Scientific MPA020 Agate Mortar And Pestle Set
This United Scientific model uses premium agate stone and features a 2″ (approximately 50.8 mm) outside diameter with a capacity of about 8 ml. The octagonal mortar is crafted from naturally hard agate stone, with a Mohs hardness around 6.5. Tolerances are stated at ±3 mm, ensuring consistent dimensions for routine lab use and straightforward sample preparation. Ideal for classrooms, laboratories, and compact kitchen experiments where precise, non-absorbing grinding is desired.
Buying Guide: Key Purchase Considerations
When selecting an agate mortar and pestle, consider your primary use case, material quality, and maintenance needs. Pure agate surfaces provide chemical resistance and non-absorption, which is essential for accurate spectroscopic analysis and clean grinding. For laboratory applications, match internal diameter and depth to the expected sample volume to avoid spillover and ensure efficient grinding.
Size and capacity: Larger sets offer more grinding surface and higher capacity, but require more desk space and may be heavier to handle. Smaller, handheld options are convenient for quick prep and small sample work. Durability depends on the stone’s hardness and finish; natural Brazilian agate with a polished or octagonal form tends to resist chipping and abrasion better over time.
Surface finish and porosity: Non-porous agate reduces absorption of sample residues, crucial for infrared and other spectroscopic methods. Some sets emphasize infrared non-absorption; verify this if your workflow depends on spectroscopy.
Compatibility with lab workflows: If you work with very fine powders or require regimented particle size distribution, look for precise tolerances and consistent dimensions. For culinary uses, consider ease of cleaning and any accessories, such as anti-scratch protectors, that preserve the surface when grinding sticky or oily ingredients.
Maintenance: Clean promptly after use to prevent staining or residue buildup. Use mild soap and water, and dry completely to prevent moisture-related issues. Avoid harsh solvents that could dull the surface over time.
Cost and availability: Compare similar models across different brands to weigh price against durability and precision. Availability may vary by region, and some models are more widely stocked in lab suppliers than kitchen retailers.
