Product Details
Laboratories in fields such as chemical synthesis, material
science, and environmental testing rely on high-purity oxygen for
critical processes—from catalyst activation and aerobic
fermentation to gas chromatography (GC) carrier gas
supplementation. The psa oxygen generator (Pressure Swing Adsorption Oxygen Generator), a specialized pressure swing adsorption oxygen plant, operates on psa technology for oxygen generation to physically separate oxygen from ambient air using high-purity
molecular sieves, delivering 99% pure oxygen without chemical
impurities or contamination risks. Compared with traditional
high-pressure oxygen cylinders, it eliminates the hazards of
transportation and storage, ensures constant purity, and adapts to
the intermittent, high-precision demands of laboratory work. This
25Nm³/h model, optimized for lab environments with compact design
and intelligent control, has become an indispensable piece of
equipment for medium-to-large research laboratories and pilot-scale
test facilities.
Laboratories face unique oxygen supply challenges: strict purity
requirements, intermittent demand, and zero tolerance for safety
risks—all addressed by psa oxygen generator:
- Purity stability vs. cylinders: High-pressure oxygen cylinders often suffer from purity
degradation (down to 97% after repeated use) due to valve
contamination, risking experiment failure. The PSA plant’s 99%±0.5%
purity and trace impurity control (≤100ppm) ensure consistent
results across experiments.
- Safety vs. cylinders: Cylinders pose explosion risks during transportation and storage,
requiring dedicated pressure-resistant rooms (infeasible for small
labs). The PSA plant uses low-pressure adsorption (0.6MPa) and
built-in overpressure protection, eliminating these hazards.
- Convenience vs. cylinders: A 40L oxygen cylinder lasts only 3-4 hours for a 5L fermentation
tank, requiring frequent replacement (increasing researcher
workload). The PSA plant operates 24/7, with a 1Nm³ buffer tank to
meet peak demand during parallel experiments.
Both belong to pressure swing adsorption oxygen plant technology, but their laboratory applicability differs sharply:
- psa oxygen generator: Advantages include compact size (2.0m×1.1m×1.8m), fast start-up
(≤2 minutes), and low maintenance—ideal for medium-scale labs (8-12
experiment stations) with intermittent, variable oxygen demand. The
25Nm³/h model’s frequency conversion design reduces energy use by
30% during overnight experiments (low load).
- vpsa oxygen generator (Vacuum Pressure Swing Adsorption): Uses vacuum regeneration for
lower energy consumption but has a larger size (≥4m×2m×3m), higher
initial investment ($15,000-$20,000), and longer start-up time (≥10
minutes). It is designed for industrial pilot plants (≥50Nm³/h
demand), not standard research laboratories.
- Key decision factor: For 90% of research laboratories, the PSA plant’s balance of
size, cost, and flexibility makes it superior to VPSA.
Laboratory oxygen equipment requires strict quality control—choose psa oxygen generator manufacturers with lab equipment expertise:
- Laboratory certification focus: Prioritize manufacturers with ISO 13485 (medical device) and GLP
compliance, not just industrial oxygen certifications. Their
products meet the strict hygiene and purity requirements of lab
work.
- Customization capability: Ensure the manufacturer can adjust parameters like pressure
(0.1-0.5MPa) and flow rate (15-28Nm³/h) to match specific equipment
(e.g., low pressure for cell culture, high flow for pilot-scale
reactors).
- After-sales support: Require on-site installation and training for researchers, plus a
2-year warranty. Manufacturers should offer technical support
within 24 hours (critical if oxygen supply fails during
time-sensitive experiments).
- Instrument compatibility: Confirm the plant can integrate with laboratory control systems
(e.g., SCADA) to enable automated oxygen supply for continuous
experiments (e.g., 72-hour fermentation).
The 25Nm³/h 99% high-purity PSA Oxygen Gas Plant redefines laboratory oxygen supply by combining oxygen plant psa technology with lab-specific precision and safety design. Its 99% purity,
stable performance, and low long-term cost solve the core pain
points of traditional oxygen cylinders, while its compact size and
quiet operation fit seamlessly into laboratory environments. For
researchers, it eliminates the hassle of cylinder management and
ensures experiment reproducibility; for laboratory managers, it
balances budget constraints with long-term value. As laboratory
research becomes increasingly complex and high-precision, the psa oxygen generator will remain a critical tool for advancing scientific
discovery—proving that reliable, pure oxygen supply is as essential
as state-of-the-art instruments in modern laboratories.
