Manufacturer: Beckman Coulter Model: J-26S XP BioSafe Three-Phase Description: The J-26S X sets the  (more)standard for performance, including high speed, low heat dissipation, imbalance tolerance and low noise level, and its wide range of separation capabilities is extended even further, now including three-phase filtration that further separates airlock material into solids, liquids and gases. The addition of a High Efficiency Particle Arrestance (HEPA) filter set makes the unit bio-safe. The J-26S XP centrifuge features a more impact-resistant lid, full containment barrier and automatic rotor detection. The ergonomic design - with lower unit height and hands-free door operation - remains unchanged. The J-265 XP can process six liters of fermentor output in less than 10 minutes, deliver a subcellular fraction at 82,000 x g, and run 24 microplates simultaneously. The unit automatically detects which rotor is installed and prevents the rotor from exceeding its maximum speed. It enables faster, quieter and more energy-efficient operation with better temperature control. The exclusive, high-torque SR (Switched Reluctance) drive reduces cycle times. Core features: - Processing six liters of digester output in less than 10 minutes. - Deliver a subcellular fraction at 82,000 x g - Run 24 microplates at once - Separate live cell populations with elutriation - Sterile filters prevent the escape of infectious material Specifications: Maximum speed: 26,000 rpm Acceleration: Maximum, slow or timed (1-10 minutes, 0-500 rpm). Deceleration: Maximum, Slow, Timed (1-10 minutes from 500-0 rpm) or Off Maximum capacity volume range: 1 - 6 L Refrigeration system: CFC-free, non-ozone depleting refrigerant Temperature range(s): 10°C - 40°C in 1 degree increments Weight: 290kg Dimensions (W x H x D): 71cm x 86cm x 86cm Power requirements: 220/380 VAC, 50 Hz, 3 phases Humidity restrictions:< 95% (non-condensing) Scope of delivery: - J-26S XP BioSafe Three-Phase without rotor - Instruction manual as PDF via e-mail If you need a suitable rotor, we are happy to help! The unit is in absolute top condition and has been 100% function tested.

Max speed: 6000 rpm Max RCF: 2000 x g Max capacity: 6 x 1.5/2ml Dimensions: (WxHxD): 153 x 128 x 109 (more) mm Weight: 730g

Edwards Silencer for nXDS and XDS5/10 Dry Scroll PumpsFeatures - Compact design combines both filtra (more)tion efficiency and noise reduction - Integrated inlet diffuser optimizes sound attenuation - Multi-stage noise reducing features including final stage sound absorbent insert - Tubular silencing design - tube is positions to maximize attenuation and air flow while minimizing pressure drop - Patented high grade element with built-in butterfly gasket seal which creates positive seal between housing hemispheres and a new seal with each element - Seamless drawn housings - no welds to rust or vibrate apart - Durable carbon steel construction with black powder coated finish - Ability to mount vertically or horizontally The Edwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps has two main functions: to reduce exhaust noise during pump down and gas ballast operation as well as to collect and retain tip seal dust as the pump is operated. Exhaust gases exit the exhaust port when the pump is being used to evacuate a process chamber, or when the gas ballast control is being used, or both. The noise level when pumping down rises as the throughput increases and the silencer is used to reduce this noise level. The outer can is made of pressed steel and is split to allow access to the filter elements. The filter element housing is made from Santoprene thermoplastic elastomer. The element itself is polyester. The foam block is manufactured from filter foam. INCLUDED: The Edwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps includes: - NW25 Clamp - Centring Ring - Manufacturer's Documentation - 1 Year Manufacturer's Warranty
