Micro-PetralabMicro-Petralab
Complete Automatic Thin Sectioning Center


The Micro-Petralab is a complete thin sectioning center incorporated into one compact, precision-built unit. It will simultaneously perform all operation necessary to obtain the highest quality thin sections while saving valuable lab space. For initial slabbing and surfacing, the unique satellite chucks can securely hold four rock specimens of any shape up to approximately 130 cubic centimeters each. The vacuum chuck will hold up to four mounted specimens for trimming and grinding. Surface grinding is performed by two built-in precision grinding heads. For finishing operations, a variable speed diamond lapping plate is included that can be easily interchanged with optional polishing plates. Also included is a handy trim saw for incidental trimming and sizing of specimens.

The Micro-Petralab is heavily constructed of the highest quality noncorroding materials and carries our warranty for two full years. Superior engineering and the finest precision craftsmanship truly make the Micro-Petralab the ultimate in fine thin sectioning equipment.

Features Specifications

Vacuum Chuck

Holds (4) 27 x 46 mm glass slides (standard). Other sizes available are: (3) 1" x 3", (3) 2" x 2", and (2) 2" x 3". Chuck "rapid travels" between saw cuts to save time and has a vacuum on/off valve at each station.

Satellite Chucks Holds 4 rock specimens of odd shapes up to approx. 130 cubic cm ea. Chucks slowly rotate as specimens are fed to the saw blade for even, consistent cutting.
Automatic Feeding System Electronically controlled, variable speed drive. A specially designed adjustable slip clutch maintains constant, even cutting pressure. Eliminates "jam-ups" and prevents damage to machine or specimen.
Grinding Heads

Two included. Automatically surface grinds specimens mounted in the satellite and vacuum chucks. Each head includes a 4" dia. diamond grinding wheel, large dia. micron dial adjustment (graduated in 3 micron increments), and adjustable stop screw.

Lapping Center 8" dia. diamond lapping plate, variable speed control (0 to 400 rpm), and adjustable coolant supply. Lapping plates are easily interchanged with optional polishing plates.
Trim Saw Built-in unit with exclusive tilt-out feature makes changing blades fast and easy. Includes fold-back blade guard and coolant system.
Spindles Precision machined from stainless steel with adjustment to completely eliminated "end-play". Stainless steel ball bearings, pre-lubed, sealed and housed in a precision stainless steel quills.
Spindle Motor 3/4 HP, 2 speed motor. If required, the motor may be easily removed without affecting the machine alignment.
Diamond Blades Main Saw: 8" dia. x .045" thick, 1/8" diamond depth, continuous rim. Trim Saw: 6" dia. x .035" thick, 1/8" diamond depth, highest quality segmented type.
Coolant System Built-in recirculating pump. Pull-out stainless steel coolant tray for easy cleaning. Coolant is supplied to the cutting area with flow control. Provisions for using tap water cooling for ultra-purity and cooling efficiency.
Size 25" (63.5 cm) wide x 23" (58.4 cm) high x 30" (76.2 cm) deep.
Net Weight 325 lbs. (147.2 kg)
Power Requirements 120V 60HZ for Domestic Model or 240V 50HZ for Export Model
