Stable Performance Low Temperature Incubator – ToronCubator™ SPLT
The ToronCubator™ SPLT is a programmable laboratory incubator built for biochemical research and controlled-temperature studies that demand both precision and flexibility. Spanning five chamber sizes from 100 L to 800 L, this series of laboratory incubators operates across a 4–70 °C range and delivers tight temperature fluctuation of ±0.5 °C during heating — making it a dependable workhorse for high-throughput research labs, pharmaceutical quality control, and advanced environmental testing environments across North America.
The ToronCubator™ SPLT is a full-featured biochemical incubator engineered to meet the demands of laboratory environments that require multi-segment programmability, access-controlled operation, and long-duration incubation scheduling. The series is available in five chamber volumes — 100 L, 150 L, 250 L, 400 L, and 800 L — giving procurement teams the flexibility to match instrument capacity to laboratory throughput without oversizing or undersizing the installation.
The outer housing is constructed from cold-rolled steel with a static spray-plastic surface treatment, while the interior working chamber uses mirror-finished stainless steel for corrosion resistance and ease of cleaning. Shelving is adjustable to accommodate samples of varying heights, and each shelf supports up to 15 kg. An inner observation glass door and a transparent glass view window allow users to inspect samples without opening the main door, preserving the internal thermal environment during sensitive runs.
Built-in test ports on both sides of the chamber — 30 mm internal diameter — provide convenient pass-through access for data cables, probes, or tubing without compromising internal conditions. The integrated 220V power socket adds further versatility for peripheral instruments placed inside the chamber. A mechanical door lock combined with a screen lock and password-protected screen saver prevent unintended parameter changes in shared laboratory settings, an important feature where multiple users access the same incubators throughout the workday.
Power recovery functionality ensures that all programmed settings and run-state data are retained after any power interruption, protecting both long-cycle biochemical incubation protocols and complex multi-segment programs from data loss.

Theory and Method
PMMA II Microprocessor Control
The ToronCubator™ SPLT operates on a PMMA II control platform that continuously samples the internal temperature sensor and modulates heating and cooling output to maintain the programmed set-point. Temperature resolution is 0.1 °C, with fluctuation held to ±0.5 °C during heating and ±0.7 °C during active cooling cycles. An over-temperature alarm and built-in self-diagnosis function alert operators to out-of-range conditions before they affect sample integrity. The color LCD backlight display provides a clear, real-time readout of all operational parameters.
Multi-Segment Programmable Profiles
The SPLT supports up to 30 programmable segments arranged across 99 repeatable cycles, allowing researchers to design complex thermal profiles — including ramp-and-soak sequences, step gradients, and multi-phase incubation — without manual intervention. A reservation function (0–9999 min) allows delayed start scheduling, and a timer function (0–9999 min/h) governs total run duration. This programmability is particularly useful for protocols in biochemical and pharmaceutical research that require tightly defined temperature histories.
Centrifugal Fan Air Circulation
A centrifugal fan with 6-stage speed regulation circulates conditioned air uniformly throughout the working chamber. This forced-convection approach achieves a temperature uniformity of ±1.0 °C at 37 °C for models up to 400 L, and ±1.5 °C for the 800 L model. Users can adjust fan speed to match the airflow sensitivity of their samples — lower speeds for fragile cultures, higher speeds for rapid temperature equilibration after door opening. The imported compressor unit operates with low acoustic output and consistent thermal performance across the full duty cycle.
Access Control and Data Protection
A screen lock timer and password-protected screen saver prevent unauthorized or accidental parameter changes during active runs — a practical safeguard in multi-user laboratory environments. A mechanical door lock provides physical security for the working chamber. The power recovery function retains all programmed data and run-state information when power is interrupted, ensuring that no incubation data or program configurations are lost during electrical events.
