Leland has developed packaged gas products from 1.0ml to 2.2 liters of water capacity. Our ability to design and deliver is unmatched in this segment of non-refillable cartridges and cylinders.




Steel bodies of all sizes are utilized to safely hold high pressure gases. Our design process often begins with the requirements of the program with respect to the outside diameter.  From there, we work with our customer to develop the most suitable gas package for their program.

Providing gases and their application so as to enrich life and further science

Learning about gases is fundamental in most university science learning labs. Leland believes that starting this process in high school is very important. Leland offers many institutions the opportunity to utilize small gas cartridges for experimentation  and teaching.
