Eppendorf 5402 Manual Updated -
The Eppendorf Centrifuge 5402 is a legacy refrigerated benchtop microcentrifuge known for its reliability in molecular biology applications. While newer models like the Centrifuge 5420 have succeeded it, maintaining the 5402 requires adhering to original technical specifications and updated maintenance standards. Core Technical Specifications Maximum Speed: 14,000 RPM (approx. 16,000 x g). Temperature Range: -4∘Cnegative 4 raised to the composed with power C 40∘C40 raised to the composed with power C , providing stable cooling for sensitive samples.
Capacity: Typically holds 18 tubes (1.5 mL or 2.0 mL) using the standard fixed-angle rotor.
Timer Control: Digital adjustment from 1 to 99 minutes, plus a "momentary" button for short spins. Updated Maintenance & Safety Guidelines
Eppendorf has updated general centrifuge care protocols that apply to legacy models like the 5402 to ensure operational safety: Centrifuge 5420 - Eppendorf eppendorf 5402 manual updated
