Problems solved by technology

Unfortunately, due to the lack of corresponding equipment, the vacuum fusion sealing of such glass containers in the laboratory can only be done manually, and skilled glass workers are required to operate, but it is still difficult to achieve a high fusion sealing pass rate ( That is, the airtightness is good, and the vacuum degree can be kept unchanged for a long time), and the efficiency is low
Although Chinese utility model patents 00214173.6 and 200720065143.6 respectively describe the ampoule fusion sealing machines they designed, neither of these two fusion sealing machines can perform vacuum fusion sealing operations

Abstract

The invention provides a vacuum ampoule sealing machine, and relates to the technical field of biochemical experiment equipment. The vacuum ampoule sealing machine mainly comprises a rotary type vacuum connector, a rotary drawing ampoule or a test tube clamp, a lifting bracket and a sealing and heating device. The vacuum ampoule sealing machine has the advantages that the vacuum ampoule sealing machine overcomes the defects of the prior art, has the characteristics of simple structure, convenient operation, high efficiency, good sealing quality and high qualification rate (as high as 100 percent), is particularly suitable for long-term oxygen isolation sealing preservation of little biochemical products or samples which are easily oxidized, decomposed, denatured and inactivated in air and frozen and dried in an ampoule or a test tube, such as microbe strains, animal and plant cells or tissues, vaccine, viable bacteria preparation, enzyme preparation, active protein, blood products, flavor food, health-care food and biochemical drugs, and suitable for vacuum sealing preservation of all oxygen-sensitive biological and chemical substances.

Description

Technical field [0001] The invention relates to the technical field of biochemical experimental equipment, and is suitable for vacuum-sealing ampoules or glass test tubes for packaging unstable biological and chemical samples, especially freeze-dried biological and chemical samples, so as to preserve the samples for a long time. Background technique [0002] Many biological and chemical samples used in scientific research need to be stored under vacuum drying due to their instability, such as microbial strains, animal and plant cells or tissues, vaccines, live bacteria preparations, enzyme preparations, active proteins, blood products, flavored foods, health care Foods, medicines, etc. usually need to be stored in an oxygen-proof seal after drying, or stored at ultra-low temperature or even liquid nitrogen temperature. Although the storage of liquid nitrogen does not require vacuum, the rapid drop of liquid nitrogen causes the fluctuation of storage temperature and the storage qu...
