No, the material is free of any nutrients or chemicals. It is completely inert.
No the ink is made of inert material and will not affect the results of any experiment.
No. The pouch is designed to be used only once. Re-using the pouch will contaminate the media and alter the results.
Yes, the pouch can be autoclaved. The pouch is designed to withstand that process. However, the polypap stand will not withstand autoclave temperatures.
Yes, the trough can be refolded at the second set of perforations to form a larger trough.
By the moistening the trough prior to placing the smaller seeds in the trough, they should remain in place.
By capillarity. The trough has small perforations that allow the root to pass through, making the root development visible. The seeds are placed in the trough located at the top of the pouch and the water is deposited at the bottom of the pouch. The water moves upwards via the germination paper. Once it reaches the trough, it will moisten the seed.
Around two weeks. Usually by the second week the germination paper will start to break down and mold may appear.
The stand has 11 slots and we recommend no more than 2 to 3 pouches per slot.
In most cases, 17 to 20 ml should suffice.
It varies. Some seeds will consume the water faster than other seeds. The best criteria is to keep the wick moist at all times. When the wick starts to dry up, add 10 ml. of water.
Yes, It is.
No, but it should not carry any contaminants.
The regular pouch is 7 inches high (18 cm) by 6 1/2 inches wide ( 16.5 cm). The longer (large seed) pouch is 14 inches high (36 cm) by 6 1/2 inches wide (16.5 cm).
