VWR浓缩离心机

For use with all CentriVap® centrifugal concentration systems, except DNA system.
 

CentriZap® strobe light enables user to shine a strobe light into the chamber to easily view samples while the rotor is spinning. Samples appear to be standing still. Includes a holster bracket (with mounting hardware) that attaches to the right side of the unit. Glass lid provides additional protection from solvents and corrosives that attack acrylic. Vacuum controller provides manual control and monitoring of vacuum levels. Analog gauge shows vacuum from 0–762mm Hg (0–30" Hg). Three-way valve is polypropylene and has an O.D. of 1.3cm (¹/₂"). Bleed valve bleeds vacuum manually when using cold trap with other laboratory equipment. Vacuum tubing kit includes two 1.3cm (¹/₂") I.D. vacuum tubing pieces, 121.9cm (48") in length, and four tubing clamps. Two-port manifold allows freeze drying of small volume samples in freeze dry flasks, serum bottles, or ampules using a CentriVap® system. Glass trap insert protects cold trap reservoir and lid from corrosives. Clear polypropylene canister with mounting bracket attaches to the side of the cold trap. Includes 43.2cm (17") PVC tubing and two clamps. Canister with stand recommended when more than one chemical trap is required.
 

Rotary vane direct drive vacuum pump is two-stage, oil-sealed and sliding-vane with cast aluminum casing. Its displacement capacity at 60Hz is 117L per minute. A 1L bottle of vacuum pump oil and two inlet adapters, 1.3cm (¹/₂") O.D. and 1.9cm (³/₄") O.D., are provided with the rotary vane vacuum pumps. They are recommended for use with aqueous and high boiling point solvents. Diaphragm vacuum pumps are fluoropolymer resin-coated and corrosion-resistant. Vacuum outlet is 1.3cm (¹/₂") O.D. They are recommended for use with volatile and low boiling point solvents.
 

Accessory rotors are constructed of anodized aluminum and hold tubes at an angle to maximize surface area. Rotors are available standard, or with a fluoropolymer resin coating that ensures resistance to acids. Hexagonal rotor holds one hundred thirty-two 1.5–2.0mL microcentrifuge tubes. The 12–17mm rotor holds a maximum of 76 tubes: up to fifty-two 12–13mm tubes and up to twenty-four 16–17mm tubes. The 12–13mm rotor holds a maximum of 148 tubes: forty 1.5–2.0mL microcentrifuge tubes and up to one hundred eight 12–13mm tubes. The 28mm rotor holds 44 tubes: thirty-two 1.5–2.0mL microcentrifuge tubes and twelve 28mm tubes. Microtiter plate rotor holds four standard or two deep well plates. The DNA rotor holds a maximum of 132 tubes: up to seventy-two 0.5mL and up to sixty 1.5–2.0mL microcentrifuge tubes.
