BEING BOV Series Laboratory Vacuum Ovens
BEING Vacuum Oven – BOV Series for Laboratory Applications
The BEING vacuum oven BOV Series is designed for laboratory thermal processes performed in an airtight chamber under reduced pressure or in a controlled atmosphere. Five chamber capacities are available, from 24L to 216L, allowing laboratories to select a model according to sample volume and process requirements.
Key Features and Benefits
- PID temperature control: PT100 temperature sensing and PID control support an operating range of Ambient +10°C to 200°C.
- Vacuum processing: The stated maximum degree of vacuum is 133 Pa when used with a suitably sized pump and correctly configured system.
- Two heating configurations: BOV-20, BOV-50 and BOV-90 use four-sided jacket radiant heating. BOV-120 and BOV-210 use individual shelf heating.
- Inert-gas inlet: An inlet connection supports suitable inert-gas or air purging workflows.
- Sample observation: A double-layer observation window and LED lighting help users view the chamber interior.
- Safety features: The series includes temperature-related protection and electrical protection features.
BEING Vacuum Oven Models and Chamber Capacities
The BOV Series includes five models: BOV-20 (24L), BOV-50 (53L), BOV-90 (91L), BOV-120 (125L) and BOV-210 (216L). The first three models use adjustable shelf heights, while the BOV-120 and BOV-210 have fixed shelf positions with individual shelf heating.

Vacuum Pump Recommendations
The BOV vacuum oven requires an external vacuum pump. BEING’s brochure recommends a dual-stage pump with a KF25 fitting. The listed pump flow rate and estimated evacuation time vary by oven model.
| Pump specification | BOV-20 | BOV-50 | BOV-90 | BOV-120 | BOV-210 |
|---|---|---|---|---|---|
| Recommended pump type | Dual-stage | ||||
| Pump fitting | KF25 flange | ||||
| Recommended pump vacuum, with ballast | 4 × 10⁻³ Torr | 4 × 10⁻³ Torr | 3 × 10⁻³ Torr | 3 × 10⁻³ Torr | 3 × 10⁻³ Torr |
| Recommended pump vacuum, without ballast | 2 × 10⁻² Torr | 2 × 10⁻² Torr | 6 × 10⁻³ Torr | 6 × 10⁻³ Torr | 6 × 10⁻³ Torr |
| Recommended flow rate | 2 L/sec | 2 L/sec | 4 L/sec | 4 L/sec | 6 L/sec |
| Estimated evacuation time | 1 min | 1 min | 2 min | 3 min | 4 min |
These evacuation times are brochure estimates, not guaranteed process times. Actual performance depends on pump selection, chamber loading, connections and operating conditions. BEING also lists V-Series diaphragm pumps as an option; their stated ultimate vacuum is 800 Pa, so they should not be described as achieving the BOV oven’s 133 Pa specification.
The pump power outlet is available on BOV-20 and BOV-50 only and is rated for intermittent use. For continuous pump operation, BEING recommends an external electrical outlet. The brochure states that the oven is supplied with a KF25 seal, hose-barb flange adapter, split-ring clamp and 14 mm ID vacuum hose.
Applications of Laboratory Vacuum Ovens
Vacuum drying can support moisture removal, removal of residual lubricants and outgassing from suitable samples. Processing under reduced pressure can also help limit oxidation for compatible materials. The inert-gas inlet supports suitable purging workflows. Always confirm material compatibility, solvent handling, temperature limits and laboratory safety procedures for the intended process.

Does the BOV Series include a vacuum pump?
The oven uses an external vacuum pump. Confirm whether a compatible pump is included in the specific quotation or purchase configuration.
What is the difference between the BOV models?
The models differ in chamber volume, shelf configuration, dimensions and heating type. BOV-20 through BOV-90 use four-sided jacket radiant heating, while BOV-120 and BOV-210 use individual shelf heating.
Can inert gas be introduced into the chamber?
Yes. The series has an inert-gas/air inlet with an 8 mm hose barb. Confirm gas compatibility and the correct operating procedure for your application.
What connection does the vacuum pump use?
The oven uses a KF25 vacuum port. The brochure lists a KF25 pump fitting and connection accessories supplied with the oven.
