Ohaus e-E51LD0403 Endeavor 5000 Orbital Shaker

A budget-friendly, programmable everyday shaker

The Ohaus e-E51LD0403 is a digital orbital shaker in the Endeavor 5000 line, positioned as a budget-friendly, programmable option for everyday shaking in incubators, cold rooms, and general lab use.

Unlike some competitor light duty shakers, it ships ready to mount accessories directly on its included tray, without requiring a separate tray purchase first.

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 high speed.

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 400 rpm, down to 1 kg at 800 rpm
• Standard tray holds 7×10 ml, 6×125 ml, 6×250 ml, or 4×250 ml vessels
• Speed adjustable in 1 rpm increments for fine mixing control

Incubator and cold room compatibility

The e-E51LD0403 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.

• Everyday orbital shaking in incubators and cold rooms
