GE healthcare Streamline 25 Column-cover
GE healthcare Streamline 25 Column

Expanded bed adsorption (EBA) is a single pass operation to recover target molecules such as protein (more)s from crude stock feedstock without prior clarification. In extracellular processes, EBA is effective in capturing molecules from fermentation or cell culture. In intercellular processes with soluble molecules, it is suitable for use with broth from cell lysis or homogenization. Streamline columns are specially designed for use with Streamline adsorbents. Column design incorporates spacial flow distributors and a moveable adaptor. The distributor at the bottom of the column creates the stable fluidized bed required for the technique. The moveable adaptor allows the bed height to be adjusted for elution in sedimented bed mode. Diameter: 25 mm Column cross section: 491 mm2 Tube height: 1000 mm Stand foot print: 430 x 430 mm Sedimented bed height: 150 – 300 mm Sedimented adsorbent volume: 75 – 150 mL Max pressure: 1 bar Operating temperature: 4°C to 40°C Feed application: 200 – 400 cm/h Elution sedimented bed: 50 – 150 cm/h Elution expanded bed: 100 – 300 cm/h Chemicals used with Streamline 100 column: Acetic acid: Concentration – 25%, pH = 1.8; Time/cycle – 3 h Acetone: Concentration – 2%; Time/cycle – 15 min Ammonium sulphate: Concentration – 2 M; Time/cycle – 5 h Ethanol: Concentration – 20%; Time/cycle – 24 months Ethanol: Concentration – 70%; Time/cycle – 1 h Ethanol/Acetic acid: Concentration – 20%/10%; Time/cycle – 3 h Ethylene glycol: Concentration – 50%; Time/cycle – 3h Guanidine-Hydrochloric acid: Concentration – 6 M; Time/cycle – 5 h Glycerol: Concentration – 10%; Time/cycle – 3 h Hydrocloric acid: Concentration – 0.1 M, pH = 1; Time/cycle – 1 h Isopropanol: Concentration – 30%; Time/cycle – 3 h Sodium acetate/Ethanol: Concentration – 0.2 M/20%; Time/cycle – 24 h Sodium chloride: Concentration –  0-3 M; Time/cycle – 3 h Sodium hydroxide: Concentration – 2 M, pH = 14; Time/cycle – 24 h Sodium hydroxide: Concentration – 0.01 M, pH = 12; Time/cycle – 12 months Sodium sulphate: Concentration – 1 M; Time/cycle – 3 h Triton X 100: Concentration – 1%; Time/cycle – 5 h Tween: Concentration – 1%; Time/cycle – 5 h Urea: Concentration – 8 M; Time/cycle – 5 h

Nasco Life/form Advanced Venipuncture and Injection Arm-cover
Nasco Life/form Advanced Venipuncture and Injection Arm

This revolutionary training arm provides complete venous access for IV therapy and phlebotomy, plus  (more)sites for intramuscular and intradermal injections. An extensive 8-line vascular system allows students to practice venipuncture at all primary and secondary locations, including starting IVs and introducing Over the Needle IV Catheters. The venous system simplifies setup with only one external fluid bag supplying artificial blood to all veins simultaneously. The dorsal surface of the hand includes injectable metacarpal, digital, and thumb veins. The antecubital fossa includes the median cephalic, median basilic, and median cubital veins. Venipuncture can also be performed along the basilic, cephalic, accessory cephalic, and median antebrachial veins. Intramuscular injections may be performed in the deltoid muscle and intradermal injection sites are located in the upper arm. Intramuscular injections into the deltoid muscle are enhanced by the soft, lifelike skin and by the natural bony landmarks in the region. Intradermal injections using distilled water will create characteristic skin welts at designated sites on the upper arm. The realism of the Life/form® Advanced Venipuncture and Injection Arm is truly amazing. The soft, flexible fingers are molded separately with extreme attention paid to every detail – right down to the fingerprints! Flexion of the wrist helps students develop manipulation skills. The replaceable skin rolls as the veins are palpated, and a discernible pop is felt when entering the veins. The Life/form® molding process reproduces the fine details of the skin to make the arm look and feel alive. Valves in the veins can be seen and palpated on the skin surface. Simulated veins and skin are completely replaceable to keep this training arm looking and working like new. Under normal use, hundreds of injections may be performed before the veins or skin need to be replaced. Complete replacement kits are available and easy to use. To extend the life of the veins, an aerosol sealant is available to seal punctures and prevent leakage.Includes 2 uarts of simulated blood, 3 cc syringe, 12 cc syringe, needle, two fluid bags, instruction manual, and soft carry case.
