Supplier:  Sigma Aldrich Fine Chemicals Biosciences Z4114931EA

DuoSeal high vacuum pumps are effective for drying using large vacuum manifolds and are ideal for vacuum distillations concentrating drying and degassing applications. The <0.001 torr ultimate pressure results in superior drying performance for the most difficult samples. Belt-drive pumps are known for their durability. Low pump rpm reduces wear and minimizes temperature to reduce oil degradation. The large oil capacity dilutes contaminants for extended service life.Required but not included - exhaust filter catalog number Z412163.Model 1400 specifications Pumping speed 0.9 cfm (25 L/min)Max. vacuum 1 x 10-4 torrOil capacity 0.62 qt (0.59 L)Tubing needed I.D. 7/16 in.Exhaust and intake thread type 3/4 -20Rpm 580Dimensions L x W x H 17.8 x 9 x 12.61 in.
