The E-Prep 4x™ grinding and polishing machine, 
with the PH-4i™ power head, is a simple yet 
powerful system for semiautomatic operation, ideal 
for low to medium volume sample preparation 
requirements. The user-friendly microprocessor-
based system makes it easy to enter parameters 
and operate, and allows quick changes to sample 
force, cycle time, platen speed and sample speed.
Either standard or magnetic 8"/203 mm or 10"/254 
mm platens may be used with any adhesive, non-
adhesive or magnetic system disc.
Durable: Engineered and constructed using 
precision machined, hard-anodized aluminum and 
stainless steel components to provide 
maximum longevity.  
Easy to Use: Straightforward controls and 
user-friendly functions allow quick, easy, 
repeatable operation.
Standard/magnetic platens, sample holders 
and accessories are sold separately.

The PH-4i™ power head offers excellent versatility 
for low to medium volume semiautomatic sample 
preparation, using individual force mode. The 
pneumatic-electric system provides controlled sample 
force and allows between one and four samples up to 
2" (51 mm) diameter to be prepared simultaneously. 
The unique tilt-up design provides easy, unhindered 
access to the sample holder and platen, and eliminates 
the need to reposition the head during the preparation 
procedure.
Simple push-button allows easy attachment and removal of 
sample holders.
Power Head Features:
• Pneumatic system to control sample force
• Unique tilt-up feature for easy access to platen and
  holder
• Individual force sample preparation of up to four (4)
  samples
• Variable individual sample force: 0-12 lb. in 1 lb. 
  increments (0-55 N in 1 N increments)
• 0.33 HP (250 W) motor with durable reduction gearbox 
  for constant high-torque output
• Variable sample rotation speed: 0-150 RPM (10 RPM
  increments) with complementary rotation
• Simple push-button attachment and removal of sample 
  holders
• Quick-lock system to allow sample holder positioning 
  across platen radius
• Compatible with #5-37XX series sample holders
PH-4i™ individual force configuration: four (4) individual pistons 
apply force to each mount (1.5" mounts shown).
Unique tilt-up feature allows easy access to platen and holder.
Retractable coolant nozzle allows quick and easy sample/bowl cleaning.

Individual Force Holders
Single Diameter Mount
Variable Diameter Mount
Individual force holders allow one or more samples to be 
prepared simultaneously. The advantage of individual 
preparation is that it allows removal of any number of samples 
from the grinding/polishing operation without affecting balance 
of the system. It is also ideal for applications where small 
geometry and site-specific cross-section requirements make 
alignment of more than three (3) samples to a common plane 
extremely challenging.

 Aluminum Tray / Shelf
This durable aluminum cabinet accommodates up to 10 
aluminum trays/shelves (reversible) for storage of platens, 
discs or cloths up to 12" (305 mm) diameter. The hinged, 
clear plastic door with magnetic lock prevents dust 
contamination. Five (5) trays are included.
Recirculating System
The recirculating filtration system allows up to 3-stage 
filtering down to 2 microns and is mounted in a durable 
cabinet that supports Allied grinding/polishing machines. 
The environmentally friendly filtration system saves up to 1/2 
gallon of water per minute with quick-change filters. System 
includes cabinet/stand, roll-out reservoir with 7-gallon (26.5 L) 
capacity and pull-out storage drawer.

Magnetic Platens
Standard aluminum platens are precision lapped parallel, 
then hard anodized for maximum wear resistance. They are 
used with adhesive backed discs, double sided adhesive 
discs and paper holding bands, or when converting to a 
magnetic platen using magnetic bases.
Disc holding bands are made of anodized aluminum and 
secure plain back discs to a standard platen. A protrusion 
around the top of the band allows variable sized discs 
(± 3 mm) to be secured.
These reusable ferromagnetic stainless steel discs feature a 
nonslip backing and allow adhesive backed cloths/abrasive 
discs to be changed quickly and easily when using magnetic 
platens.
Double sided adhesive discs are adhered to a standard platen 
and used to secure plain back silicon carbide abrasive discs. 
Each provides 25-75 disc pulls depending on grit size, cycle 
time and force.
Magnetic platens combine a standard aluminum platen with 
a cross-hatched magnetic surface for maximum flatness 
and adherence. Only one platen is needed throughout the 
grinding and polishing process, allowing all magnetic system 
cloths/abrasive discs or ferromagnetic discs to be utilized.
