FINGERPRINTS DETECTION APPARATUS

PS 189 Thermostatic Ninhydrin Heater (Portable Type)

This carrying case style unit is designed to accelerate the Ninhydrin reaction when processing latent fingerprints thermostatically. Full development of the Ninhydrin reaction may take more than twenty-four hours, but this unit makes it possible to process within only several minutes (using 20 to 30 sheets of B4 size papers). The source of the heater is an infrared radiation tube lamp which shortens the process, and heats the objects evenly and efficiently. The power can be taken from an ordinary household power source.

PS 185 Thermostatic Heating Chamber (Large Type)

This is a large-sized heater for processing fingerprints with ninhydrin or cyanoacrylate in a laboratory setting. The inner temperature can be adjusted manually, depending on the reagents to process, and the amount of objects. To have effective heating and energy saving, the inside is dividable into a maximum of four rooms by the size of the objects . There are four observation windows on the top, to monitor the development.

PS 81 Infrared Rays Lamp Heater

This is a handy heater for processing fingerprints with ninhydrin, cyanoacrylate and other methods multi-purposely. The source of the heater is an infrared rays lamp which shortens the process, and heats and dries the objects evenly and efficiently. It is able to ventilate without heating, using a fan only.
