Description

The YR06698 Seed Germinator is a 600 L growth chamber designed for agricultural research, quality control, and germination tests under reproducible environmental conditions. It offers a temperature range of 10–65 °C with illumination and 5–65 °C without illumination, controlled humidity of 40–95 %RH (±5 %RH), thermal uniformity of ±1.5 °C, and accuracy of ±0.1 °C. It incorporates adjustable lighting from 0–15,000 lx in 5 levels (20/40/60/80/100 %), a 0–99 h timer, and a gentle airflow circulation system that ensures uniform temperature throughout the chamber. The mirror-finish stainless-steel interior and height-adjustable shelves facilitate cleaning and the configuration of different cultivation heights.

The unit integrates PID control with a programmable microprocessor and LCD screen, over-temperature alarms, balanced refrigeration with programmable automatic defrost, and multiple protections for continuous operation. Its international-brand compressor features time-delay protection for stable operation. The double-door design with a tempered-glass viewing window allows you to observe samples without disturbing the microclimate. Built with an eco-friendly design philosophy, it uses low-impact R-290 (propane) refrigerant.

Frequently Asked Questions (FAQ)

Is the illumination range sufficient for germination and early growth?
Yes. The 0–15,000 lx range covers germination and seedling stages in multiple species. If your protocol requires a specific PPFD or LED spectra, modules and diffusers can be configured.

How does it maintain temperature and humidity uniformity?
Through optimized air circulation and PID control, achieving ±1.5 °C uniformity and ±0.1 °C accuracy, together with programmable defrost to prevent thermal spikes.

Can it operate 24/7?
Yes. It is designed for continuous operation, with compressor protections and integrated alarms. Preventive maintenance is recommended.

What maintenance is required?
Periodic cleaning of the stainless-steel interior, filter checks, sensor verification, and annual temperature/humidity calibration.

Advantages and Disadvantages

Advantages
• Broad environmental control: 5–65 °C (no light), 10–65 °C (with light), 40–95 %RH, 0–15,000 lx.
• Uniformity and accuracy: ±1.5 °C / ±0.1 °C with PID and air circulation.
• Professional construction: stainless-steel interior, adjustable shelves, double door with viewing window.
• Sustainability: low-impact R-290 refrigerant.

Possible disadvantages
• Infrastructure requirements: 3.8 kW power draw and space consistent with a 600 L chamber.
• Higher initial investment compared to units without humidity control or of smaller volume.

Usage in the Field:

In agronomy and seed laboratories, the YR06698 standardizes germination (viability, vigor, and accelerated aging tests) under programmable temperature/humidity/lighting protocols. In plant research centers, it enables photomorphogenesis and abiotic stress assays with high repeatability. In industrial quality control, it ensures comparable lots via time-based profiles (e.g., 12/12 h light–dark cycles and thermal ramps), with records useful for internal audits.

Recommendations:

• Plan the setup: define the lux range by species, shelf height, and thermal load (number of trays).
• Calibration and verification: validate temperature and humidity with traceable standards at least once a year or per internal policy.
• Good practices: avoid prolonged door openings; use containers that do not block airflow; schedule defrost cycles outside critical periods.
• Safety: comply with regulations for R-290 equipment (adequate ventilation; no open flames).
