EGG PICKERS
MariSource has developed a lightweight plastic egg picker. In contrast to the old-fashioned hand-carved wood picker, the MariSource model will save time and eggs—and no splinters!
Design: The screw near the end of the egg picker adjusts to modify the opening. This adjustable opening enables the egg picker to be used with different sized eggs. Tension may also be altered by adding rubber bands to the end. The long narrow tip reaches those awkwardly positioned eggs embedded in expanded plastic substrates with minimal disturbance to live eggs. The length of the tip can be easily shortened with a pocket knife if desired. Overall length of the unit is 12 5/8" (32 cm).
Material: The egg picker is constructed of lightweight plastic, impervious to chemicals and solvents. It will not retain bacteria and is easily disinfected, making it sanitary for repeated use. The lightweight plastic material will not sink, an obvious benefit in working around water.

EGG COUNTER
The MariSource egg counter is equipped with specially designed indentations. Once eggs are scooped onto the paddle-like surface, they settle readily into even rows. A full counter holds 100 eggs. The egg counter is made of nontoxic, impervious and buoyant material.

DISCHARGE CONTROL KITS:
MariSource offers two options for control of treated or contaminated water from individual water trays.
|
|
|
FRONT DISCHARGE KIT
Two specially molded plastic dams are installed, one on each of the two outflow channels. The dams form a positive seal against the sides of the water tray. Plastic tubing forms a tight connection to the front of each dam. Spent water travels through the tubing to be discharged at a safe distance.
|
|
|
REAR DISCHARGE KIT
This specially modified water tray permits rear discharge of spent water. Again, two plastic dams are installed in outflow channels, but these dams are sealed. Spent water is forced backward to be discharged throughout the PVC pipe assembly shown. Plastic tubing is applied to the end of the pipe assembly, and spent water removed to a safe distance.
