Binder FD-S 56 Drying and Heating Oven, Solid.Line with forced convection, 55 l, up to 250 °C, 9090-0018

If you need to dry laboratory glassware reliably after cleaning or store samples at a constant temperature, you don’t need a high-tech cabinet – you need a robust workhorse. The Binder FD-S 56 from the Solid.Line range is built precisely for this purpose: a drying and heating cabinet with forced air circulation and a 55-litre usable volume, deliberately stripped back to the essentials. Rather than offering numerous additional functions, the Solid.Line provides BINDER’s tried-and-tested quality and reliability at a more affordable entry-level price than the Avantgarde.Line (FD series): a conscious choice for anyone looking for a solid convection drying oven without any frills.

Solid.Line instead of Avantgarde.Line: reduced but well-thought-out features

The FD-S 56 covers a temperature range from 10 °C above ambient temperature up to 250 °C. Whilst this is lower than the maximum offered by the Avantgarde.Line models (up to 300 °C), it is entirely sufficient for most routine applications in drying and heat treatment. Control is via a controller with a timer function; the APT.line preheating chamber technology ensures even temperature distribution inside the chamber despite its simpler design. The exhaust air flap can be adjusted so that the air exchange can be tailored to the specific drying process.

Heating times and energy consumption in everyday use

At 150 °C, the FD-S 56 achieves a spatial temperature deviation of 2.6 ± K and a temporal deviation of 0.4 ± K. The heating time to 150 °C is approximately 15 minutes; once the door is opened, the set temperature is reached again after about 5 minutes. The air change rate at 100 °C is 4 air changes per hour. Energy consumption at 150 °C is 290 Wh/h: a figure that has a direct impact on running costs when used frequently in day-to-day laboratory work.

Typical applications

A compact, forced-air drying and heating cabinet such as the FD-S 56 is suitable for day-to-day tasks in laboratories and quality assurance, where reliability in continuous use is more important than the highest temperature accuracy.

• Drying of cleaned laboratory glassware and sample vessels
• Warm storage and conditioning of material samples
• Simple heat treatment processes in quality assurance and training
• Routine drying in industrial and testing laboratories with limited space

With external dimensions of 614 x 577 x 625 mm and a weight of 35 kg, the FD-S 56 fits comfortably on smaller laboratory benches or in ancillary rooms, without compromising on its 55-litre capacity for day-to-day drying tasks.

Selection guide within the range

The Solid.Line FD-S series is currently available from BINDER in two sizes. Both share the same temperature range, control concept and features, but differ significantly in terms of usable volume and footprint.

Anyone who regularly dries larger quantities of laboratory glassware or sample material is better served by the FD-S 115. For day-to-day routine operation with smaller quantities, the FD-S 56 described here is generally sufficient.

Differences compared to the Avantgarde.Line, Classic.Line and natural convection

The Solid.Line is one of three equipment ranges in which BINDER offers drying and heating cabinets. It reliably covers the basic functions, but omits some of the features found in Avantgarde.Line models of the same volume, such as the FD 56: The temperature range tops out at 250 °C instead of 300 °C, and control is via a simpler controller with a timer function rather than an LCD display. In return, the Solid.Line has a lower entry-level price than the Avantgarde.Line, as described in the introductory section.

Those who require gentler heat distribution without air movement inside the chamber, rather than forced circulation, will find the ED-S 56 to be the ideal counterpart within the Solid.Line range: the same housing design, but with heat distribution via natural convection rather than via the fan found in the FD-S 56. BINDER also uses the designation Classic.Line for certain smaller models. The current master data does not provide a consistent record of which LT items belong to this third line; therefore, no specific classification is stated here. An overview of the entire Binder range available from LT Laborhandel can be found in the ‘Climate Chambers & Incubators’ category.

Application, Operation and Maintenance

In day-to-day use, the Solid.Line range really comes into its own in terms of cycle times: the heating-up time to 150 °C for the FD-S 56 is around 15 minutes; once the door is opened, the set temperature is reached again after approximately 5 minutes. The spatial temperature deviation of 2.6 ± K and the temporal deviation of 0.4 ± K at 150 °C are sufficient for most routine applications in drying and heat treatment, even though both values exceed the accuracy of comparable Avantgarde.Line models. If the door is opened frequently – for example, when loading sample vessels in stages – the recovery time of around 5 minutes has a direct impact on overall throughput during daily operation.

Practical note: Standard, non-abrasive laboratory cleaners are suitable for cleaning the interior; we advise against the use of abrasive or chlorine-based agents. The built-in Class 2 temperature limiter in accordance with DIN 12880, featuring a visual alarm, provides additional protection against accidental overheating during unattended drying cycles. Calibration is recommended for regular checks of temperature accuracy; LT Laborhandel can arrange suitable calibration certificates via its procurement service.

Investment rationale: When Solid.Line is sufficient, and when Avantgarde.Line is worthwhile

For routine tasks up to 250 °C, where a simple timer controller is sufficient, the Solid.Line meets requirements reliably and at a lower cost than the Avantgarde.Line. If, on the other hand, a higher temperature range up to 300 °C is required, an LCD display with more precise process control is desired, or the process needs to be documented, a model such as the FD 56 from the Avantgarde.Line is the more suitable choice, even if this entails a higher purchase price. For higher throughput within the Solid.Line range itself, the larger FD-S 115 model is available, rather than switching straight to the Avantgarde.Line.

The FD-S 56 comes as standard with a chrome-plated loading rack, including a base support. For higher loading densities, additional loading racks are available as accessories, as are calibration certificates and maintenance contracts of varying scope; both can be obtained via LT Laborhandel’s procurement service.

Frequently asked questions about the Binder FD-S 56

What is the usable volume of the FD-S 56?
55 litres, with external dimensions of 614 x 577 x 625 mm.

What distinguishes the FD-S 56 from the FD-S 115?
With a capacity of 106 litres, the FD-S 115 offers roughly twice the usable volume but takes up more floor space; otherwise, both models are technically identical.

What distinguishes the Solid.Line from the FD 56 model in the Avantgarde.Line?
The FD-S 56 covers a temperature range up to 250 °C, whilst the FD 56 covers a range up to 300 °C. The Avantgarde.Line is also controlled via an LCD display rather than a simple timer controller.

Is the FD-S 56 also available with a 120 V connection?
Yes, in addition to the 230 V version, the appliance is also available as a 120 V variant.

How do I clean the interior?
A mild, non-abrasive laboratory cleaner is sufficient. It is best to avoid using abrasive or chlorine-based cleaners (practical advice).

Can I have the FD-S 56 calibrated?
Yes, LT Laborhandel can arrange the relevant calibration certificates via its procurement service.

What is included in the scope of delivery?
The FD-S 56 (9090-0018), a chrome-plated insert rack including a base support, and the user manual.
