Profile: Jule, Inc. is a manufacturer of precast gels, gradient formers and electrophoresis products. Our gradient gels provide sharper bands and they separate a broader range of molecular weight sizes on the same gel. Our cassettes are made by molding two cassette halves and ultrasonically welding them together & the leak tight bond is made on 3 sides of the cassette & this enable to pour gel solutions into the cassettes without leakage.
