Analysis furnace LV 3/11

preheatingheatinglaboratory

Product overview
Ashing furnace series LV / LVT (models 3/11–15/11) is engineered for laboratory ashing up to 1050 °C (design Tmax 1100 °C). Typical uses include loss on ignition, ashing of food and plastics and other standardized laboratory ashing methods (ISO, ASTM, EN, DIN). A dedicated fresh‑air and exhaust system provides more than 6 air exchanges per minute; incoming air is preheated along the furnace heating to improve temperature uniformity.

Standard equipment

• Tmax 1100 °C
• Dual‑sided heating with ceramic heating plates (integral heating element, protected and replaceable)
• Air exchange >6 times/min
• Preheated incoming air for improved temperature uniformity (DIN 17052‑1: ±10 °C from 550 °C)
• Dual‑shell stainless steel housing with additional fan cooling for low external surface temperature
• Insulation materials without CLP classification (EC Reg. 1272/2008)
• Controller B510 with touch operation (5 programs × 4 segments)
• Solid state relays for low‑noise operation
• NTLog Basic for process data recording via USB
• Variants: front hinge door (LV) or lift door (LVT)

Additional equipment

• Adjustable over‑temperature limiter for protection of furnace and load
• Thermocouple port in rear wall or furnace door
• Charging racks with closed or perforated trays for two‑level loading; tray holder for insertion/removal up to 800 °C (max. load per layer: e.g. 2 kg for LV(T) 9/11, 3 kg for LV(T) 15/11)
• VCD software package for process control, monitoring and documentation
