Description

IKA A11 basic Analytical Grinder: Performance and Precision in Grinding

The IKA A11 basic grinder is an essential tool for laboratories and industries where size reduction of solid samples is critical. With its two grinding methods, impact and cutting, it allows for the adjustment of operational parameters to suit the characteristics of the materials being processed.

Impact grinding is ideal for hard and brittle materials, such as cereals or roots, providing efficient size reduction with minimal loss due to its sealed closure system. This method is particularly useful for fragile or frozen materials. Cutting grinding is suitable for softer, fibrous materials like paper, hay, or certain spices. This system ensures precise cutting without excessive heating, an important factor in preserving the properties of the processed samples.

The A11 basic is designed for ease of use and speed. The integrated universal motor allows for impressive rotation speeds of up to 28,000 rpm when idle and up to 25,000 rpm under load. These speeds are automatically adjusted to prevent clogging or overloading, ensuring stable performance. The grinder is equipped with an overload protection switch to prevent overheating, extending the device's lifespan and providing optimal safety for the user.

The device also features a high-quality ETFE fluoropolymer grinding container, offering excellent chemical resistance and the ability to withstand extreme temperatures ranging from -200°C to +150°C, making it ideal for use with refrigerants such as liquid nitrogen or dry ice. This functionality is especially useful for materials that require cooling before grinding, such as certain viscous or oily substances.

Weighing only 1.5 kg, the IKA A11 Basic is a lightweight, easy-to-handle and portable device. Its compact and robust design allows it to be placed on any laboratory work surface while remaining stable during use.

In terms of maintenance, the A11 Basic requires minimal upkeep. Simple cleaning is sufficient to keep the device in good working condition, and the grinding tools can be easily replaced with a straightforward fastening system.
