Using the Grass Compression Gland

Watch this video on YouTube

The Grass Compression Gland can be used to seal samples of bladed grass. If the grass is has a rounded blade, you can use the regular Compression Gland. The Grass Compression Gland can seal samples up to 3/4" wide and a maximum center width of 1/8" wide. The opening is slightly eliptical - it is tapered toward the edges. It can be used on any type of bladed grass that will fit in it. Also will work young corn leaves. The seal is not wide enough for adult corn leaves.

Prepare the sample to be sealed.

Insert the sample from the bottom of the lid.

Push the sample so that it barely protrudes through the top of the lid.

The end of the sample will look something like this.

Tighten the Compression Gland by twisting the Compression Screw clockwise.
