Laboratory and industrial hot air ovens, 50–300 °C, gravity or forced-air convection, 28 L to 200 L+, digital PID control.
Samarth Electronics is an ISO 9001:2015 certified hot air oven manufacturer in India and a direct hot air oven exporter to Bangladesh. Buyers looking for a reliable hot air oven supplier in Bangladesh get factory-direct pricing, a machine built for 220 V / 50 Hz, and complete export documentation, with no trading margin in between.
A hot air oven heats samples and equipment with circulating hot air in an insulated chamber. It is the most versatile heating instrument in labs and plants. Typical uses are drying glassware, dry-heat sterilisation at 160 °C, moisture determination, pharmaceutical stability studies, and curing coatings and adhesives.
In Bangladesh, our hot air oven is used by QC labs of export-oriented pharma companies; pharma plants in Gazipur, Savar, Tongi and Narayanganj; and university labs in Dhaka and Chattogram. Export units for Bangladesh are built for 220 V / 50 Hz and shipped by sea to Chattogram, by air to Dhaka, or by road through the India–Bangladesh land ports, with a commercial invoice, packing list, certificate of origin and technical datasheets.
Samarth Electronics makes two configurations. Gravity convection suits fragile or light samples. Fan-assisted forced-air convection gives ±2 °C uniformity across all shelves for stability testing and component curing. Chambers range from 28 L to 200 L+, all with an SS 304 interior, digital PID control, a timer and an independent over-temperature cut-out.

| Requirement | Recommended | Notes |
|---|---|---|
| Small lab (1–6 items) | 28 L | Gravity or forced-air |
| QC department | 50 L | Forced-air for uniformity |
| Lab group / production batch | 100 L | Multiple shelves |
| Stability testing / large batches | 150–200 L+ | Forced-air, ±2 °C |
Drying glassware (80–110 °C), dry-heat sterilisation (160 °C for 2 hours), moisture determination (100–105 °C), curing adhesives and coatings (80–200 °C), stability testing and annealing metals and plastics.
Gravity convection uses natural air movement and suits fragile or light samples. Forced-air uses a fan to give ±2 °C uniformity across all shelves, which stability testing and component curing need.
Yes. Dry heat at 160 °C for 2 hours sterilises clean metal instruments and glassware that cannot be autoclaved. The oven should be validated for temperature uniformity.
28 L for a small lab, 50 L for a QC department, 100 L for a lab group or production batch, and 150–200 L for stability testing or large industrial batches.
Units are built for 220 V / 50 Hz and shipped by sea to Chattogram, by air to Dhaka, or by road through the India–Bangladesh land ports. Each shipment includes a commercial invoice, packing list, certificate of origin and technical datasheets.
