BIOSTELLAR Programmable Vacuum Drying Oven

Product features

• Heat where the sample sits. Independent heated shelves deliver heat at the loading surface. Select single-layer or double-layer heating to suit the arrangement of the batch.
• One controller for routine and staged methods. The 5.0-inch LCD touchscreen uses multi-stage PID temperature control. Fixed-value and program modes accommodate both repeat runs and methods with changing temperature requirements.
• Plan the heating ramp. In fixed-value mode, the heating rate can be set. Program mode allows the temperature and duration of each step to be defined.
• Choose when timing begins. Fixed-value operation offers timing from start-up, timing at the set temperature or accumulated timing, so the timer can follow the method.
• Follow the temperature history. Real-time temperature curves show how the run develops. Parameter memory after power interruption helps retain entered settings.
• Connect vacuum and inert gas separately. Dedicated evacuation and gas inlet valves support vacuum operation and the introduction of an inert gas for oxidation-sensitive work.
• Keep the chamber visible and sealed. A reinforced tempered-glass window allows visual checks. Adjustable door closure and a one-piece silicone seal support chamber sealing.
• Protect the method settings. An overtemperature alarm, independent temperature limiter, sensor-fault diagnostics and menu or parameter locking help operators manage abnormal conditions and unintended setting changes.

Applications

• Drying heat-sensitive laboratory samples with a sample-specific temperature schedule.
• Processing materials that readily decompose, using a drying temperature selected for the material.
• Drying and heat treatment of oxidation-sensitive materials under reduced pressure or an introduced inert gas.
• Laboratory heating, testing and temporary sample holding where reduced oxygen exposure is required and the process is compatible with the oven.

1. Which chamber sizes are available?

The series offers 24, 53 and 91 L chambers. Select the capacity around the sample containers and batch layout, rather than volume alone.

2. What temperature and vacuum specifications are stated?

The operating temperature range is ambient temperature +10 °C to 250 °C. The stated vacuum specification is <133 Pa; temperature resolution is 0.1 °C and temperature fluctuation is ±1 °C.

3. How are the samples heated?

The oven uses independent heated shelves. Single-layer or double-layer heating can be selected to match the loading arrangement.

4. Can I run a multi-step drying method?

Yes. Program mode lets you define the temperature and duration of each step. Fixed-value mode is available when a constant set temperature is sufficient.

5. Can inert gas be introduced into the chamber?

Yes. The chamber has a gas inlet and a separate evacuation connection. Gas type and operating conditions should be chosen for the sample and the laboratory procedure.

6. Is the vacuum pump included?

The source lists the vacuum pump as an optional item. Confirm the pump and connection configuration when ordering.

7. Can I view curves and connect to external equipment?

Real-time temperature curve recording is included in the described controller functions. An RS485 interface, printer and external or remote communication functions are listed as options and require configuration confirmation.

8. What protection and setting controls are provided?

The oven includes an overtemperature alarm, an independent temperature limiter and sensor-fault diagnostics. Menu or parameter locking helps prevent accidental changes to the method.
