It is used to sterilize or dry glass and metal material used in examinations or tests, which is converted to the laboratory and comes from the washing section, where it is sent after being used in a procedure. Sterilization carried out in the oven is called dry heat and is carried out at 180 ° C for 2 hours; Glassware, when heated by high temperature air, absorbs moisture and eliminates the possibility of maintaining any biological activity due to high temperatures and times used.

Quality control on stoves is a bit difficult to achieve because the dry heat sterilization technique has the critical temperature and time setting. In general, the spores of Bacillus Subtilis, the Niger variety, which must be incubated for several hours after the use of the sterilization process as biological indicators. The initial spore load of the biological indicator varies between 5 x 105 and 1 x 106. Its effectiveness depends on the diffusion of heat, the amount of heat available and the loss of heat. The action of the microbicide is conditioned by the presence of organic matter or dirt in the article. Dry heat sterilization should be limited to materials that cannot be autoclaved.

Types of Laboratory ovens a Laboratory May Need

Vacuum Ovens

  • Vacuum environment greatly reduces the need to get rid of the liquid boiling point, so the vacuum
  • Drying heat-sensitive material can be easily applied for is not easy to Drying the sample, such as powder or other granular samples using a vacuum Drying can effectively shorten the Drying time.
  • Safety-under the conditions of vacuum and inertness, completely avoid exploding if oxidizing material in a very high temperature.
  • Compare with the ordinary drying way depend on air circulating to drying, powder sample is not easy to be blew away by flowing air.
  • Interior chamber use streamlines arc design, the outer is made of cold-rolled steel plate, the surface uses the electrostatic spray.
  • Liner is made of stainless steel or cold rolled material, easy to clean because of corners semicircular.

Industrial Oven

  • According to the box size single door or double door design. Large diameter centrifugal wind wheel. Uniform heat circulation.
  • The shell is made of high quality cold-rolled steel with metallic paint spray. Nice overall color design. suitable for all workshop production.
  • Digital display intelligent temperature controller with microcomputer intelligent PID control and timing function.
  • Large diameter centrifugal wind wheel. uniform heat circulation.
  • Two models material inner chamber: mirror stainless steel and zinc-plating.
  • This series product with the feature of large storage and temperature rising is fast.
  • YR05256 for the smaller product baking such as baked paint for toys hardware part.
