Applications
The Yamato SK-401-115V is a compact, dependable dry heat sterilizer suited for labs that need consistent sterilization performance without the footprint of larger units. Its 99 L chamber and natural convection heating make it a practical choice for benchtop and smaller-scale sterilization workflows.
Glassware Sterilization & Depyrogenation
Dry heat is the preferred method for sterilizing and depyrogenating borosilicate glassware — flasks, pipettes, petri dishes, and volumetric ware. The SK-401-115V reaches 260°C, sufficient for validated depyrogenation cycles, and natural convection ensures gentle, even heat penetration without disturbing lightweight or open glassware. No residual moisture means instruments are ready to use immediately after the cycle completes.
Metal Instruments & Heat-Stable Supplies
Forceps, scalpels, spatulas, needles, and other metal instruments that cannot tolerate moisture are well-suited for dry heat sterilization. The SK-401-115V's programmable 99-step controller allows validated sterilization protocols to be stored and recalled for consistent, repeatable results — useful for labs running multiple instrument types on different cycle parameters.
Powders, Oils & Moisture-Sensitive Materials
Talc, starch, petroleum jelly, mineral oils, and similar materials degrade under steam sterilization conditions. Dry heat at controlled temperatures is the only validated approach for these substrates. The SK-401-115V's PID control and calibration offset function allow precise cycle conditions to be set and documented, supporting GMP and quality assurance requirements.
Research & Clinical Laboratories
The SK-401-115V is well-suited for smaller research labs, satellite facilities, and clinical settings where a full-size sterilizer isn't needed but validated dry heat performance is still required. Programmable auto start/stop functions support unattended operation, and the compact 99 L footprint fits comfortably in space-constrained lab environments.
