title: [Simple technic for multiple small sample lyophilization].
abstract: This simple and easily reproducible technique does not pretend to be new in principle but is still very convenient for drying numerous samples. The advantage of the technique is based on preliminary sample freezing just before dessication. The tubes must be sealed with needle punctured cellophane to avoid the samples squeezing out by ice-entraped air bubbles. This approach is especially convenient for protein structure investigations when it is necessary to dry and accumulate peptides from the maps on high-voltage electrophoresis and chromatography. In a 1.5-litre dessicator some 20 ml of sample can be dried out without reloading.
