Spencers Seed Germinator (Model No. : 3330-SSG-001 series)

SPENCERS Seed Germinator provides unmatched consistent reproducible environmental conditions automatically for uninterrupted operation. The “user-friendly” controls in the seed germinator are easy to use and allows the control of almost any combination of temperature, light intensity, humidity parameters, water insertion and time options, with greater accuracy.

The Seed germinators are designed for accommodating high volume seed / test needs, as well as versatile, meeting many test requirements that may require a controlled single set point temperature, alternating temperature patterns, light, dark or alternating light periods. Accurate and reliable controls in the seed germinator are easy to use, making this an excellent choice for running special tests, as well as optional built-in memory to allow repetitive test procedures to be easily stored and retrieved.

SPENCERS Seed germinators are versatile testing chambers and would typically include meeting specific requirements of temperatures, humidity and light level intensity, such as: pre-chiller, seed germination, seed tests and research, plant test and research, plant growth, propagation, accelerated aging, photo stability tests, zoology, botany, tetrazolium, biological research and tissue culture tests.

Seed Germinator Heat / Refrigeration system

Heating system

Level, constant heat is continually maintained through a water media, by specially designed high purity magnesium oxide and helically wound nickel-chrome wire heating elements. Elements are totally enclosed for efficient heat transfer and operator safety. The warm air is evenly distributed throughout the chamber through efficient motor fans ensuring a very good temperature sensitivity.

Refrigeration  system

SPENCERS superior refrigeration system with optional Backup refrigeration system. Uniform refrigeration is maintained through the use of air-cooled, high torque, hermetically sealed condensing unit. High quality cooling system components include: efficient fan circulation evaporator coil with thermal expansion valve, moisture-liquid indicator, filter drier, heat exchanger, and pressure control valve. All refrigerant lines are copper and fully insulated.


Heavy duty Air-cooled compressor. The compressor is distinguished by its excellent performance, low noise level (<60dB) and minimal vibration.


Highly efficient condenser with automatic condensate evaporating system.


Internal evaporator system Forced draught


Non-CFC/HCFC environmental friendly based on compressor capacity.

Air Circulation

Forced air circulation to maintain chamber uniformity.

Seed Germinator Air-Humidity Circulation

Humidity System

Unique forced air circulation design maintains an even, continuous, moist airflow throughout the cabinet. Perforated trays further enhance even humidity distribution to testing samples. Self-contained stainless steel water reservoir in each chamber assures a relative humidity of 90%. Temperature variation between trays is ±0.5° C, top to bottom.

Seed Germinator Control System

Control System Standard

The standard control system consists of Micro-processor based independent temperature controllers for Heat, Cool  & Humidity mode with LED/LCD display. The illumination is controlled through solid state cyclic timer to control the photoperiodic cycle of the chamber. Optional alarm system for various parameters.

Control System Advanced

The advanced control system features robust PID Controllers with process control settings or micro-controller/Micro-processor based Control system. The control system has various optional features such as LED/ LCD Display Printer Report Program, Data Acquisition Program, Timer, Light control, Adjustable alarm limits, and Process cycle settings etc. customized to meet end user requirements.

Power Supply

220 volts,50 Hz / 110 volts,60Hz.
