title: [Method of purifying glutaraldehyde for microscopic research on biological objects].
abstract: A simple and reliable method of purification and determination of glutaraldehyde concentration for histochemical fixation is proposed. Purification of glutaraldehyde is provided by vacuum distillation with a rotational-filmy evaporator, and its concentration is determined using refractometer.
