Disposable serological pipettes with polyester fiber plugs are ideal for tissue culture applications. Crisp, black, highly legible permanent graduations prevent ambiguity and guarantee precise reading and accurate dispensing within ± 2%. Reverse graduations show volume removed or remaining on all pipettes larger than 1mL. Generous negative graduations provide additional pipetting volume. Yongyue's serological pipettes are made from transparent USP Class VI polystyrene sterilized by gamma irradiation. Each lot is free from pyrogens, DNases, and RNases.Yongyue's plastic serological pipettes are produced under the strictest protocols and offer the highest degree of accuracy.
10, 25 and 50mL pipettes feature three-piece construction

After the face recognition system was formally used at the opening ceremony of the Beijing Olympics, the face recognition technology has received extensive attention in the country and has been promoted in applications such as access control and attendance.
Face Recognition Technology Overview Face recognition is based on human facial features. For the input face image or video stream, first identify the characteristics of each part of the face, the position information of each major facial organ, and based on these information, further extraction Biometrics contained in human faces are compared with stored face templates to identify people.
Facial recognition algorithm is widely used in face recognition technology. It integrates computer image processing technology and biostatistics principles. It uses computer image processing technology to extract portrait feature points from video and uses biometrics. The principle of learning is analyzed to establish a mathematical model, namely a face feature template. Using the established face feature template and the subject's face image for feature analysis, a similar value is given based on the results of the analysis. Through this value, it can be determined whether the same person.
The pipettes are supplied with an aerosol barrier plug that prevents both liquid and aerosols from contaminating the pipettors.
The serological pipettes are produced from crystal clear polystyrene (PS) and are color coded for easy volume identification. Available in 1mL, 2mL, 5mL, 10mL, 25mL and 50mL sizes.
In addition each Pipette now features:
Crisp and bold easy-to-read graduation marks
Reverse graduations on all volumes
Negative graduations on all volumes
1, 2 and 5mL pipettes feature one-piece construction
Face recognition method technology overview
Emerging - Face Recognition Face recognition technology in China is the most gorgeous debut of the 2008 Beijing Olympic Games. The opening and closing ceremonies of the Beijing Olympic Games will be subject to real-name management. Ticket holders are required to submit personal information and identity photographs in advance, and use face recognition technology for real-name authentication when the audience enters the venue to eliminate potential security loopholes. Improving the level of Olympics safety precautions and anti-terrorism technology, this is the first time in the history of the Olympics to use face recognition technology as an intelligent means of personal identification to introduce Olympic security.
