Rigid design for higher reproducibility

Tegramin has an exceptionally sturdy design to improve reproducibility, increase specimen planeness, and lower noise during preparation. The specimen mover is fixed on a solid construction with a massive cast aluminum base. The up/down movement is based on two strong columns, making the entire systems as solid as possible. This ensures the least possible vibration for higher sample accuracy and reproducibility.

Method database for accurate preparation from day 1

Tegramin includes 10 Struers Metalog Guide methods, covering all major material groups. The methods have been developed for maximum performance on Tegramin and allow you to get started right away, with minimal learning time. The methods also provide an excellent starting point for developing your own methods. These can easily be stored in the database for fast and easy preparation.

Advanced dosing for different preparation tasks

Tegramin can be used with three different dosing modules to cover a wide range of preparation tasks, depending on your needs. • Module with one pump for DP-suspension or lubricant • Module with two pumps for DP-suspensions or lubricants • Module with two pumps for DP-suspensions or lubricants and one pump with a water connection for OP-suspension The modules can be combined in various ways, giving you up to 7 pumps in total and many different combinations.

Bowl flush for fast and easy cleaning

To facilitate fast and easy cleaning, the Tegramin-30 and Tegramin-25 are equipped with a bowl flush function. When the function is activated, disc cooling occurs while the disc is rotating. Any water that is sprayed onto the bottom of the MD-disc is distributed to the walls of the bowl. This washes away loose debris, making cleaning easier.

Transparent cover for safe work environment

An optional transparent cover is available to enclose the entire preparation area. When alcohol-based consumables are used, all the fumes are contained within the cover. The cover can also be connected to an exhaust so that all fumes are removed, making a safer working environment for operators.

MD disc with cone for fast bowl liner change

The easy-to-remove MD disc allows for a fast change of bowl liner. It also has a higher mass than traditional MD discs, so it keeps the temperature of the preparation surface lower and can easily be cooled down using the disc cooling function.

Removable bowl liner for fast cleaning

Tegramin’s bowl liner fits precisely into the bowl and collects all debris that is not washed down the drain. When the machine has to be cleaned, the bowl liner can easily be removed. It can then either be cleaned or discarded.

LED light for easier operation

The LED light illuminates the entire preparation area and makes it easy to follow the preparation process. When not used for 10 minutes, the Tegramin will enter standby mode, which saves electricity and reduces energy consumption.

Emergency stop for greater safety

The emergency stop button immediately stops all moving parts.It is placed so it is easy to reach when working with the machine.

Recirculation cooling system for cost-efficient water use

Cooling water minimizes heat when grinding. One of Struers' recirculation cooling systems can be connected to Tegramin. This ensures cost-efficient water utilization and collects removed abrasives – to lower your water consumption and reduce the amount of classified products spent. The recirculation cooling unit is especially useful to avoid blocking of the draining system in the lab and improves your environmental performance by ensuring waste and debris is collected in the filters and not washed down the drain. It is also very useful when there is no water connection nearby.

Easy operation with multifunction (turn/push) knob

Tegramin is designed with a large color display for easy operation. Navigation within the software is simple and it is very easy to change parameters using the turn/push knob.

Material removal sensor for shorter grinding time

Tegramin’s built-in removal sensor ensures the shortest possible grinding time and saves you time on subsequent fine grinding or polishing steps. When using time to measure material removal, there is a risk of too much material being removed, especially when working with multiple samples. Measuring material removal instead will ensure you only remove the material required, saving you time in the next process step. Tegramin’s material measurement can be set to between 50 - 5,000 μm. This ensures only the necessary amount of material is removed – and guarantees the shortest possible grinding time.

Automatic specimen mover plate lock increases accuracy

When the specimen mover plate has been moved into the correct position over the preparation surface, the coupling can be locked inside the specimen mover using a single screw. This eliminates any small movements in the specimen mover plate, resulting in significantly improved sample planeness.

Prepare single specimens or several specimens in a holder

To increase process flexibility, Tegramin can be used to prepare single or multiple specimens. • Prepare a single specimen or an uneven number of specimens with a specimen mover plate. This is faster as you simply have to place the specimens on the preparation surface. • Prepare multiple specimens by clamping them in a specimen holder. This is ideal when working with multiple specimens, even if they are of different shapes and sizes.
