Ohaus e-E51LD0420 Endeavor 5000 Orbital Shaker

A larger-orbit Endeavor 5000 for general-purpose flask work

The Ohaus e-E51LD0420 is a digital orbital shaker in the Endeavor 5000 line, using a 20 mm orbit rather than the 3 mm orbit of its e-E51LD0403 sibling, for general-purpose flask culture work.

Aside from the orbit size and the corresponding speed range, it shares its programming, connectivity, and construction with the rest of the Endeavor 5000 family.

Triple eccentric drive keeps the tray flat

A triple eccentric drive and maintenance-free brushless DC motor keep the tray flat through the full speed range, with no vertical wobble to cause splashing, even at higher loads.

This is a specific advantage over competitor shakers using a single-eccentric drive, where tray wobble at higher speed is a common cause of sample splashing.

On-board programming and recall

A simple on-board menu sets, stores, and recalls up to 8 separate programs of up to 5 steps each, for reproducible multi-step protocols.

The recall feature retrieves the last 5 recently used settings, and RS232 connectivity (with an optional USB or Ethernet interface kit) supports PC control and data logging.

• Weight capacity of 4 kg at 300 rpm
• Standard tray identical to the e-E51LD0403’s volume capacity
• Speed adjustable in 1 rpm increments for fine mixing control

Incubator and cold room compatibility

The e-E51LD0420 is rated for -10°C to 40°C, 80% RH non-condensing, which covers incubator and cold room use, though it is not rated for the condensing environment inside an active CO2 incubator.

Avoid cold starts: bring the unit into the cold room from room temperature, operate, and remove it once the run is complete.

Included tray and optional Universal Platform

The standard aluminum tray (300 x 222 mm) has 11 mounting points for accessories and a non-slip rubber mat included.

The optional Universal Platform (30770938) expands capacity from 39 x 10 ml up to 3 x 1 L flasks, unlocking the full accessory range for this model.

Ideal Applications

The Ohaus e-E51LD0420 suits the following applications.

• Everyday orbital shaking of Erlenmeyer flask cultures
• General-purpose mixing in incubators and cold rooms
• Budget-conscious labs needing programmable shaking
• Labs replacing a single-eccentric competitor shaker prone to splashing
• General cell culture and extraction work

Choose the e-E51LD0420 when:

• You need a general-purpose 20 mm orbit rather than a micro orbit
• You want a programmable, budget-friendly light duty shaker
• You need to run the shaker in an incubator or cold room
• You want to avoid buying a separate tray before mounting accessories
• You want to store and recall multi-step programs

Ohaus Value Proposition

The e-E51LD0420 combines a triple eccentric drive, on-board programming, and a ready-to-use accessory tray, for dependable general-purpose flask shaking at the Standard Digital price tier.

Ohaus positions the Endeavor 5000 line as the current flagship of its Standard Digital tier, above entry-level analog models and below the Premium Incubating/Cooling range.
