REFLEX Analytical offers a complete line of compact, hand-operated benchtop presses engineered to produce tablets, pills, pellets, and KBr pellets from powdered materials. These economical laboratory presses provide precision and reliability in a small footprint, eliminating the expense of larger tablet-making machinery while delivering polished, uniform samples with clean ejection and minimal contamination.
Designed for use across pharmaceutical, biological, nutrition, spectrographic, clinical, and research laboratories, the presses are ideal for tasks such as bomb calorimetry, emission spectroscopy, IR spectroscopy, and routine sample preparation. Compact dimensions and a simple lever-driven mechanism make these tools versatile for bench-top workflows.

Standard die sizes range from 2 mm to 13 mm. Custom intermediate sizes are available upon request. Smaller dies (4.5 mm and under) are machined from 17-4PH stainless steel. Larger dies (1/4 inch and up) use T-303 stainless steel. All die components are heat treated for added strength and hardness.
Typical cavity depths:
Each press ships with a universal die holder that locates and aligns die sets precisely. Spare universal die holders are available to increase productivity - as one tablet/pellet is pressed, another can be prepared in a spare holder.
The products formed are typically cylindrical with flat ends. Thickness (height) varies according to the amount of material loaded and the compression force applied. Dies are not permanently fastened - they align with the ram and may be slipped out from under the ram for quick reloading.
Compression is developed by hand pressure on a lever attached to a large steel cam. The cam design provides a steadily increasing mechanical advantage up to approximately 50:1 at the end of the stroke. For example, 20 pounds of force applied to the lever will generate roughly 1000 pounds of pressure on the press ram. This is adequate to form firm tablets, pills, or pellets from most powdered materials, usually without the need for a binder.
The anvil that supports the die is mounted on a heavy screw post allowing it to be raised or lowered. Rotate the anvil to adjust die height - this lets you:
