The E-Prep 4™ grinding and polishing machine, 
with the PH-4i™ power head, is a simple yet 
powerful system for semiautomatic operation, 
ideal for low to high volume sample 
preparation requirements. The user-friendly 
manual and touchpad interface makes it easy 
to adjust settings and operate. Basic controls 
allow quick changes to parameters such as 
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 
plain/adhesive backed 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 and sample 
holders are sold separately.

The PH-4i™ power head offers excellent versatility for 
low to high volume semiautomatic sample preparation, 
using individual force mode. The pneumatic 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.
PH-4i™ Power Head
Simple push-button allows easy attachment and removal of 
sample holders.
Features:
• Pneumatic system to control sample force
• Individual force sample preparation of up to 4 mounts
• Pneumatically applied (manually adjustable) sample 
  force: 0-12 lb. in 1 lb. increments (0-60 N in ~ 5 N 
  increments)
• Holders available for standard mounts up to 2"/51 mm 
  diameter
• Simple push-button attachment and removal of sample 
  holders
• 0.25 HP (190 W) motor with durable reduction gearbox 
  that provides constant high-torque output
• Unique tilt-up power head for easy access to sample 
  holder and platen
• Three (3) rotation speeds: 50, 100 and 150 RPM
• Quick-lock power head adjustment and easy sample 
  holder positioning across entire platen surface
• Complementary rotation
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.

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.

The AD-5™ fluid dispenser provides automatic, 
unattended application of abrasive polishing 
suspensions and lubricants.  All functions are 
programmed using the touchpad switches on its 
faceplate. Intuitive menu navigation and simple 
logic programming make the dispenser easy to
