Jianhu Smart Touchscreen Vacuum Oven – Research-Grade Low-Temperature Drying System with One-Touch Start and Thermal Protection

Overview

The Jianhu Smart Touchscreen Vacuum Oven is an engineered solution for low-temperature, solvent-free drying of thermally labile, oxidation-sensitive, and high-value materials across pharmaceutical, food science, chemical synthesis, and materials research laboratories. Operating on the principle of vacuum-assisted sublimation and desorption—where reduced chamber pressure lowers the boiling point of solvents and water—the system enables precise moisture removal at temperatures as low as 25 °C while maintaining structural integrity, biological activity, and chemical stability. Unlike conventional convection ovens, this vacuum oven eliminates oxidative degradation pathways by isolating samples from ambient oxygen, and avoids thermal denaturation through programmable PID-controlled heating plates and real-time vacuum regulation. Its architecture complies with fundamental engineering requirements for laboratory-scale process reproducibility, including uniform temperature distribution (±1.5 °C), leak-tight stainless steel chamber construction, and validated vacuum stability down to 10 Pa (optional upgrade to 1 Pa). Designed for integration into GLP-compliant workflows, the unit supports traceable parameter logging and meets baseline mechanical safety standards per IEC 61010-1.

Key Features

• Intuitive 7-inch capacitive touchscreen interface with multi-language support (English, Chinese, Spanish) and intuitive one-touch startup protocols for standardized drying cycles
• Dual-stage vacuum control: integrated oil-free diaphragm pump (base vacuum ≤10 Pa) with optional secondary turbomolecular pump upgrade for ultra-high vacuum applications (≤1 Pa)
• Low-temperature thermal protection: automatic cut-off if chamber temperature exceeds user-defined setpoint by >3 °C, preventing unintended thermal stress on sensitive biomolecules or nanomaterials
• 316L stainless steel chamber with electropolished interior surface (Ra ≤0.4 µm), compliant with ISO 14644-1 Class 5 cleanroom surface requirements for pharmaceutical use
• Modular accessory compatibility: configurable inert gas purging (N₂/Ar), UV-C sterilization module (254 nm), and silicone-free sealing options for food-grade validation
• Real-time monitoring of chamber temperature, vacuum pressure, elapsed time, and cycle phase via on-device display and optional USB data export

Sample Compatibility & Compliance

The oven accommodates a broad spectrum of sample formats—including glass vials, aluminum trays, ceramic crucibles, and custom-designed sample holders—without compromising vacuum integrity or thermal uniformity. It is routinely employed for drying lyophilized biologics (e.g., monoclonal antibodies, recombinant proteins), heat-labile nutraceuticals (e.g., probiotics, omega-3 encapsulates), nanoparticle catalysts (e.g., Pt/C, NiFe oxides), and botanical extracts (e.g., polysaccharide-rich herbs, anthocyanin-containing fruits). From a regulatory standpoint, the system aligns with core elements of FDA 21 CFR Part 11 (when paired with audit-trail-enabled software), EU GMP Annex 15 (for process validation), and USP (sterile processing guidance). Its 316L chamber material satisfies ASTM A240 and EN 10088-1 specifications, and its construction supports cleaning validation per ISPE Baseline Guide Volume 4 (Equipment and Utilities).

Software & Data Management

While the base model operates via embedded firmware without cloud connectivity, optional PC-based software (JianhuVacControl v3.2) provides enhanced functionality: full-cycle graphing of temperature vs. vacuum vs. time, export of CSV-formatted logs with timestamped metadata, password-protected user roles (operator, supervisor, administrator), and electronic signature capability for GLP/GMP documentation. All recorded parameters are stored locally on removable USB drives in tamper-evident format, supporting retrospective review during internal audits or regulatory inspections. The system does not transmit data externally unless explicitly configured by the end user, ensuring compliance with institutional data governance policies and GDPR/CCPA frameworks where applicable.

Applications

• Pharmaceutical R&D: Low-temperature drying of peptide APIs, vaccine adjuvants, and sterile-filtered intermediates; supports formulation development under ICH Q5C stability guidelines
• Food Science: Freeze-drying of functional ingredients (e.g., lactic acid bacteria, polyphenol extracts) while preserving viability and antioxidant capacity per AOAC 993.14 and ISO 21527-1
• Materials Chemistry: Solvent removal from MOFs, perovskite precursors, and conductive polymer dispersions without agglomeration or crystallinity loss
• Environmental Analysis: Pre-concentration of aqueous environmental samples (e.g., PFAS, microplastics filtrates) prior to GC-MS or LC-MS/MS analysis
• Academic Research: Widely deployed in university labs for thesis-level work involving thermal characterization of biomaterials, catalytic kinetics, and herbal pharmacognosy studies

FAQ

What vacuum level can the standard configuration achieve?

The base system achieves ≤10 Pa using the integrated oil-free diaphragm pump. An optional turbomolecular pump module extends performance to ≤1 Pa for applications requiring ultra-low residual vapor pressure.

Is the chamber suitable for corrosive solvents such as chlorinated hydrocarbons or strong acids?

The 316L stainless steel chamber resists mild organic solvents and diluted acids. For aggressive media (e.g., concentrated HCl, HF), optional PTFE-coated shelves or quartz-lined inserts are recommended.

Does the unit comply with FDA 21 CFR Part 11 for electronic records?

The hardware supports Part 11 requirements when used with the optional JianhuVacControl software, which includes audit trails, electronic signatures, and role-based access control.

Can the oven be validated for IQ/OQ/PQ protocols?

Yes—Jianhu provides factory calibration certificates (NIST-traceable temperature and pressure sensors), and the unit’s design allows for third-party qualification using standard protocols per ASTM E2500 and ISO 13485.

What maintenance intervals are recommended for the vacuum pump?

The oil-free diaphragm pump requires no oil changes; routine inspection of inlet filters and membrane integrity is advised every 500 operating hours or annually, whichever occurs first.
