Explain how accuracy may be ensured in the techniques used for titration. Explain why a piece of laboratory tissue or tongs should be used to handle a sample container to be weighed. Why is it important in this experiment to be acc...
The apparatus consists of two arms (A, B) articulated (3) or sliding on each other; one of the arm has at one end a cup (1) for sampling a liquid and the other arm a lid for the cup. The proposed laboratory device enables accurate sampling by pipette while eliminating the causes ...
Uses of Pipette Tip Pipette Tips are attached to micropipettes and used in all fields related to chemistry and biology. Specific uses include laboratory experiments in the field of biochemistry, quality control at pharmaceutical manufacturers, and specimen collection in clinical testing. Micropipettes ar...

laboratory apparatus such as an electronic pipettors and centrifuges. The embodiments are capable of performing an extraction or purification of a variety of compounds. Further, the embodiments provide an extraction or purification method which requires a minimal number of solutions for use, which for...
Air displacement pipetters with disposable pipette tips have been used in the medical and laboratory industries for many years. The main reason for such continual acceptance comes from the fact that after each use the pipette tip has traditionally been disposed of thereby limiting the possibility of...
The invention is an apparatus for organizing and dispensing pipette tips. A hopper receives bulk pipette tips which pass through a diamond shaped apertures in a sieve and drop into the troughs of a se

These criteria are challenging to achieve since, typically laboratory workloads may demand that an automated system generate as many as 120 test results per hour. Although all instrument processes contribute to the instrument's ability to produce such results, perhaps none is more important than the...
