The Distek OLERA is a modern dissolution tester for laboratories that want to combine reliable performance with ease of use and a cost-effective configuration. Its patented heating technology enables rapid warm-up and removes the need for an external heater/circulator.

With the OLERA Select, no water bath is required. This means there is no need to replace the water or use an anti-algae agent. The large 10-inch touchscreen, precise temperature control and automatic vessel alignment support consistent test conditions and an efficient daily workflow.

Description

Reliable performance for daily laboratory routines

The OLERA builds on Distek’s 50 years of experience in developing laboratory instruments. The system combines reliable performance with simple operation and a well-organised workspace.

For laboratories familiar with the Distek Model 2500, the OLERA offers a modernised user experience while maintaining the performance they expect from Distek.

Integrated, patented heating technology

Heating and circulation are fully integrated into the system. This removes the need for a separate heater/circulator and helps keep the laboratory bench clear.

The patented technology distinguishes the OLERA from conventional systems and provides rapid, even warm-up. The temperature is controlled with an accuracy of ±0.25 °C. The standard temperature range extends from ambient temperature to 55 °C.

The OLERA Select operates without a water bath. As a result, there is no need to replace the water or use an anti-algae agent, while the system is also ready for use more quickly.

Clear operation via a large touchscreen

The 10-inch colour touchscreen provides a clear and intuitive user interface. The display is easy to read and can also be operated while wearing laboratory gloves.

Up to 500 pre-programmed methods can be stored. The system also supports up to 250 users with different access levels.

View the instrument status at a glance

The HALO status indicator makes the current status of the instrument visible from a distance. Users can quickly check whether a test is running or requires attention.

Repeatable vessel positioning with acculign+

The automatic acculign+ vessel alignment system centres and positions the vessels in a repeatable way. This reduces preparation time and helps minimise the risk of deviations caused by incorrect vessel positioning.

Optional remote monitoring with Pulse

The optional Pulse functionality allows users to view the status of a dissolution test through a web browser, without installing additional software.

Email and text notifications keep users informed about the progress and status of the system. This helps them plan their work more effectively and respond promptly when a test requires attention.

Flexible integration into the laboratory workflow

The OLERA can be operated manually or with pre-set methods. For automated workflows, the system can be connected to Distek Cipher Software, the Eclipse 5300 dissolution autosampler and the Opt-Diss 410 in-situ UV system.

Ethernet and USB-C connections support integration with additional systems and equipment.

Continuous temperature measurement with OLERA Plus

Laboratories that want to continuously measure and record the temperature in each individual vessel can choose the OLERA Plus. This model uses patented temperature sensors integrated into the drive shaft.

The sensors measure the temperature directly in the vessel without affecting the hydrodynamic conditions of the test.

Advice on your configuration

The right configuration depends on your methods, sample volumes, automation requirements and desired temperature range. Our specialists can help you select a solution that fits your laboratory and application.
