BPG-9040A Forced Air Drying Oven — 40L Precision Hot Air Oven with LCD Controller and RS-485 Connectivity up to 250°C

The BPG-9040A's 350 × 320 × 350 mm stainless steel chamber features rounded interior corners — eliminating the right-angle corners where debris, sample residues, and dried material accumulate in standard square-corner oven chambers. Rounded corners facilitate thorough wipe-clean maintenance between sample types and protocols, reducing the risk of cross-contamination from previous sample residues affecting subsequent drying batches. The stainless steel material resists corrosion from the range of chemical vapours and sample types encountered in pharmaceutical, research, and chemical laboratory oven applications.

The BPG-9040A's large LCD controller provides clear real-time display of actual and setpoint temperatures, timer status, and programme settings — with programmable timer capability up to 5999 minutes and multiple programme settings for storing frequently used protocol parameters. The LCD interface provides unambiguous parameter readout for routine laboratory operations and supports multi-programme configuration for laboratories running multiple standardised drying and heating protocols on the same instrument across different working periods.

The BPG-9040A's forced air circulation system provides active convective heat distribution throughout the 40L chamber — ensuring fast, even heating across all sample positions without the temperature gradients characteristic of natural convection ovens. Forced air circulation supports ±1°C temperature accuracy across the chamber and enables the 40L volume to reach operating temperatures rapidly — making the BPG-9040A suitable for time-sensitive laboratory protocols where oven pre-heat time is a workflow constraint.

The BPG-9040A provides 2 adjustable shelves within the 40L stainless steel chamber — configurable for diverse sample vessel heights and loading configurations. The adjustable shelf positions enable optimisation for different sample formats: lower shelf positions for taller containers, higher density configurations for small-format samples across both shelf levels, and single-shelf loading for oversized samples requiring maximum interior height clearance.

The BPG-9040A's over-temperature protection system monitors chamber temperature and activates protective shutdown and alarm if the temperature exceeds the configured safety limit — providing independent backup protection for unattended pharmaceutical drying, biotechnology sterilisation, and chemical laboratory heating protocols. The alarm system provides audible and visual notification of over-temperature and system fault conditions.

The BPG-9040A's optional RS-485/RS-232 interface enables electronic connection to laboratory data monitoring systems, LIMS, and laboratory computers — allowing continuous recording of oven temperature data for process monitoring, batch documentation, and quality management record-keeping. RS-485 connectivity supports multi-instrument network configurations where multiple BPG Series ovens report to a central monitoring system, while RS-232 enables direct connection to a single laboratory computer or data recorder.

The BPG-9040A's side test port provides a sealed access point for inserting temperature probes, sensor leads, and monitoring cables into the chamber without opening the door — enabling independent temperature verification with calibrated reference probes, continuous thermocouple monitoring of sample temperatures, and integration with external data acquisition systems. The side test port is particularly valuable for pharmaceutical stability and food safety applications where independent chamber temperature verification is a quality assurance requirement.
