Product Description

The Heidolph Tuttnauer 2340E autoclave (model HEI- 023210207) is a 19 L/5 gallon electric sterilizer with a 9 x 18” (diameter x depth) chamber, and a 120 V power source for use with standard outlets. It has four adjustable programs with temperature selections from 105 to 137 degrees C (221 to 279 F) with sterilization times up to 59 minutes for simplified and reproducible operations. The autoclave comes with three stainless steel trays for maximizing space in the chamber by holding instruments, liquids, laboratory equipment and other items to be sterilized.

A digital display continuously shows temperature, pressure, and running time. Every stage of the cycle is automatic and micro-processor controlled from water-fill, to sterilization, exhaust, and drying. The autoclave has a low water alarm for notifying users when the reservoir needs to be refilled, an in-line particle filter to protect valves, and standby heating to keep the chamber warm in between cycles. The autoclave also has a combination pressure and temperature gauge, and an automatic low water shut off to prevent damage to the heating elements if there is insufficient water for sterilization. A heat-insulated, double-locking door helps protect users from accidental burns and prevents the chamber from being opened during the sterilization cycle. The autoclave has a fast or slow exhaust selection, with the fast exhaust for drying solids, and the slow exhaust for preventing media and liquid boil-over. A closed-door drying cycle maintains sterility and removes extra moisture after sterilization. A continuous pressure purge removes air pockets and ensures even sterilization, and the 3 L reservoir has a drain located on top for simplified cleaning. The autoclave also has an automatic shut-off for conserving energy, and a battery backup ensures retention of settings and controls in the event of a power failure.

The chamber capacity is 19 L/5 gallons and its dimensions are 22.9 x 45.7 cm (9 x 18 inches) (diameter x depth); tray dimensions are 17 x 41.5 x 2 cm (6.7 x 16.3 x 0.8 inches); exterior dimensions are 38.1 x 50.8 x 50.8 cm (15 x 20 x 20 inches) (H x W x D ), and it weighs 36 kg (79 lb). (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) Electrical: 120 V, 1,400W;current: 12A.

Autoclaves are ovens that sterilize laboratory instruments and can kill bacteria, viruses or both. They are often used in laboratories to sterilize lab equipment, media and liquids, and can be designed to meet different health, safety, and environmental standards.

Top Customer Reviews

We purchased a new 2340EA several years ago for use in a veterinary practice. Our records shows 132 cycles; of these, about 100 were actual complete sterilization cycles. The rest were either cleaning cycles or misfires. We had service performed several months ago due to cycles failing. The technician found nothing wrong and the autoclave performed without flaws for him. Last week, the unit failed entirely. The same company sent another technician. The finding: The circuit board had completely failed and the power switch was also bad. The technician advised that the Tuttenauers are prone to circuit board failure. In the case of ours, we found that the spade clips that connect the wiring to the power switch were very loose. The resulting poor connection caused poor voltage to be provided to the circuit board, which is the most likely cause of the failure. The total cost of repair will be just under $1,000. For a machine that cost around $4,000, our expectations were that it would last for many more cycles than it did and that there would be no sloppiness in the assembly of the parts. We can not recommend the 2340EA as a dependable machine.
