BOXUN BXK-100S Vacuum Drying Oven

Overview

The BOXUN BXK-100S Vacuum Drying Oven is an engineered solution for controlled, low-temperature dehydration of thermolabile, oxidation-sensitive, or structurally complex samples. Operating on the principle of reduced-pressure drying—where ambient pressure is lowered to depress the boiling point of volatile solvents—the BXK-100S enables efficient moisture removal without thermal degradation. Unlike conventional convection ovens, this system eliminates convective air currents that may displace fine powders or disturb delicate specimens, while simultaneously suppressing oxidative reactions by maintaining an inert or near-vacuum environment (≤133 Pa). Designed for reproducible performance in regulated laboratory environments, the BXK-100S complies with foundational operational requirements aligned with ISO 17025 calibration traceability frameworks and supports GLP-compliant documentation when integrated with validated data management protocols.

Key Features

• Heated stainless steel shelves with distributed under-shelf heating elements—improves thermal transfer efficiency by >50% compared to jacketed heating, especially under high vacuum where gas-phase conduction is negligible.
• Independent temperature control per shelf (dual-zone capability), with real-time digital display of each zone’s setpoint and actual temperature—enabling synchronized drying of heterogeneous sample batches or energy-optimized operation with partial shelf activation.
• Integrated vacuum pump housed within a sound-dampened cabinet—reduces operational noise by up to 40 dB(A) versus external pump configurations and preserves benchtop spatial integrity.
• Digital microprocessor controller with LCD interface, featuring programmable timer (0–9999 min), over-temperature cut-off, auto-recovery after power interruption, and vacuum-level monitoring with closed-loop compensation logic.
• Double-layer tempered glass door with compression-molded silicone gasket ensures vacuum integrity and optical clarity for non-invasive process observation.
• Chamber constructed from electropolished AISI 304 stainless steel with radius-corner geometry—facilitates cleaning validation and minimizes residue retention in compliance with pharmaceutical cleaning SOPs.

Sample Compatibility & Compliance

The BXK-100S accommodates diverse sample formats including lyophilized biological matrices, ceramic precursors, polymer composites, botanical extracts, and precision-engineered components requiring solvent-free final drying. Its 100 L working volume and dual independently controlled shelves support parallel processing of multiple sample types under differentiated thermal profiles. The system meets mechanical and electrical safety standards per IEC 61010-1 and is compatible with laboratory quality systems adhering to FDA 21 CFR Part 11 when paired with audit-trail-enabled software (e.g., optional BOXUN LabLink™). Vacuum stability at ≤133 Pa satisfies ASTM E145–22 criteria for gravimetric moisture determination in pharmaceutical excipients and conforms to USP guidelines for residual solvent analysis preparation.

Software & Data Management

While the BXK-100S operates as a standalone instrument with embedded firmware, it supports RS-485 serial communication for integration into centralized lab automation platforms. Optional BOXUN LabLink™ software provides time-stamped logging of chamber temperature, vacuum level, elapsed time, and alarm events—with configurable export to CSV or PDF for inclusion in electronic lab notebooks (ELN). All parameter changes are recorded with user ID and timestamp, satisfying basic audit trail requirements for GLP/GMP-aligned workflows. Firmware updates are delivered via secure USB interface and include cryptographic signature verification to ensure integrity.

Applications

• Pharmaceutical R&D: Final drying of active pharmaceutical ingredients (APIs) and amorphous solid dispersions without polymorphic transition.
• Materials Science: Solvent removal from MOFs, aerogels, and battery electrode slurries prior to characterization.
• Environmental Testing: Gravimetric determination of total suspended solids (TSS) and moisture content in soil/sediment per EPA Method 1669.
• Food & Agriculture: Dehydration of heat-sensitive nutraceuticals and botanical concentrates while preserving volatile terpenes and phenolic compounds.
• Electronics Manufacturing: Residual solvent evacuation from conformal coatings and encapsulants prior to hermetic sealing.
• Academic Research: Controlled desolvation of coordination polymers and crystallographic sample preparation under inert conditions.

FAQ

What vacuum level can the BXK-100S achieve, and how is it maintained?
The system achieves and sustains ≤133 Pa using its integrated 2 L/s rotary vane pump; vacuum stability is actively monitored and compensated via proportional feedback control.
Is the chamber temperature uniform across the full 100 L volume?
Yes—temperature uniformity is maintained within ±0.5°C at setpoint across the working volume, verified per internal qualification protocol IQ/OQ-VD-2023.
Can the BXK-100S be used for sterilization or depyrogenation?
No—it is not designed or validated for microbial kill or endotoxin reduction; it is intended solely for drying, dehydration, and solvent removal applications.
Does the unit support external data acquisition or SCADA integration?
Yes—RS-485 Modbus RTU interface enables connection to industrial PLCs or building management systems for remote status monitoring and alarm relay outputs.
Are replacement shelves or custom-sized trays available?
Standard 2-piece stainless steel shelves are included; OEM-compatible accessories—including perforated trays, quartz sample boats, and PTFE-coated inserts—are available through BOXUN’s global distribution network.
