ATM Pneumatic Sample Leveling Press (1 min 30 sec)
Take a look at the Pneumatic Sample Leveling Press by ATM. This device helps with that tricky problem of getting all your samples level in a sample holder by using 90 psi pressure to keep that sample in place! Level samples means less grinding time, saving you time and consumables.
Optional Automatic Dosing
The external Topas Eco dosing unit can be added to the grinder/polisher at any time and is automatically controlled by the color touch screen panel.
- Four 500 ml glass bottles with screw caps can hold either 3 x suspension and 1x lubricant or 4 x all-in-one suspension
- Suspension can be replenished during operation if needed
- The bottles are easily removed for cleaning
- A backflush function keeps the dosing lines clean
- An optional magnetic stirrer helps keep your diamond suspended
The grinding/polishing head has a recessed grip on each side for 1 and 2 handed operation:
- 2 hands needed to raise or lower the head into position
- 1 hand needed to swivel head left or right
When the head is fully raised, there is ample space for easy sample holder removal.
