Travenol Laboratories Ultra Flo - II: 1974
This coil (product code 5M1755) was first produced by Travenol Laboratories, Inc., in 1974. It used a single coil of tubular Cuprophan membrane 210 mm wide and had a surface area of 1.4 m2. At a blood flow-rate of 200 mL/min, the dialyzer had clearances of urea of 133 mL/min, creatinine of 115 mL/min, and Vitamin B12 of 30 mL/min. At a venous pressure of 100 mmHg, the ultrafiltration rate was 487 mL/hr.

CF 1200 and CF 1500 capillary flow dialyzers: 1977
These dialyzers first appeared in Dialysis and Transplant in August 1978. The capillaries were made of thin-wall (16 micron) Cuprophan fibers. At a 200 mL/min blood flow-rate, the dialyzer clearances were:
- CF1200: Urea - 160 mL/min, Creatinine - 140 mL/min, Vitamin B12 - 30 mL/min; Kuf = 2.5 mL/hr/mmHg (TMP)
- CF1500: Urea - 170 mL/min, Creatinine - 130 mL/min, Vitamin B12 - 25 mL/min; Kuf = 3.5 mL/hr/mmHg (TMP)

CD 1000 and CD 1400 coil dialyzers: 1978
These dialyzers represented the culmination of 20 years of coil development for Travenol Laboratories, Inc. They used a 210 mm wide Cuprophan membrane. Both had clear cases to make visualization easier during rinsing. Having both dialysate ports on the bottom reduced splashing in the dialyzing compartment. At a blood flow-rate of 200 mL/min, the urea clearance for the CD 1000 was 110 mL/min and for the CD 1400 was 130 mL/min. At a mean coil pressure of 200 mmHg, the CD 1000 had a UFR of 450 mL/hr and the CD 1400 had a UFR of 700 mL/hr.
