The Oxford Laboratones sampler has allowed a tremendous improvement in the ACCURACY PRECISION AND SAFETY of pipatting in thousanrls of laboratories throughout the world. With the addition of the DUAL and TRIPLE range instruments it is now economically possible for every laboratory to put an end to mouth plpetting. DUALRANGESAMPLER 2 different volumes can be selected. TRIPLE RANGE SAMPLER 3 different volumes can be selected. Like the Mono-Sampler the Dual and Triple range will pick up and dispense serum or aqueous solution with a precision of 1%.
6 Meniscus reactings and the errors they cause are eliminated. The sample material is drawn into a disposable polypropylene tip. It never enters the instrument, and as a fresh tip is used for each sample there is no possibility of cross-contamination. The disposable tips are non-wetting. This eliminates the need to rinse the tip of any residual sample, and provides the advantag~ of a rapid "to deliver" technique with the precision of a "to contain" method. Many different sizes are available up to please write for details j I 1.
