Durability
- Exterior cabinet is 18 gauge cold-rolled steel, powder coated for durability and a high quality appearance that resists scratches and chipping
- 51mm (2.0 in.) thick, non-CFC, foamed-in-place polyurethane cabinet insulation provides maximum product thermal protection and increased rigidity for reliable daily use
- Phenolic-coated evaporator protects against corrosive by-products or agents in the chamber atmosphere (e.g., secretions from insects such as flies), ensuring long life
- Solid, stainless steel interior is more durable and corrosion-resistant than plastic or painted metal, ensuring long life and minimizing equipment costs
- Heavy-duty, solid, stainless steel shelves are easy-to-clean, saving time and effort; more corrosion-resistant than coated wire shelves for long life; and adjustable for convenience
- 821L models include 6 shelves that are adjustable on 76mm (3 in.) centers
- 311L model includes 3 shelves that are adjustable on 51mm (2 in.) centers
- Reinforced floor/shelf components for 821L models are available so you can use shakers, cell rollers, or other heavy equipment or product loads inside the chamber to meet a variety of applications
- Swivel, locking casters ensure easy mobility during installation and cleaning. Leveling feet provide stability and added safety in the lab.
- Directed airflow system promotes ideal growth environment by distributing airflow uniformly throughout the chamber; versus a horizontal airflow system which does not evenly distribute throughout the shelves of the chamber.
- Choice of access ports for inserting data logging sensors or cables
- Convenience receptacles to run electrical devices in chamber
- Choice of chart recorders for data logging
- Choice of data outputs for monitoring/alarm (3962 model only)
