In liquid cultures, redox reaction indicator dyes such as resazurin are added in order to determine the oxygen concentration in the broth, because it turns pink in the presence of oxygen. Also, all preparation and manipulation of samples for anaerobes are done in completely anoxic conditions therefore needing special anaerobic chambers. ...
Still, plant staff have responsibilities beyond process control sampling and would be overwhelmed if required to conduct multiple process control sampling events during each shift. While operators conduct sampling events as frequently as possible, this still leaves an eight-hour interval between manual sampling. ...

Accuracy and traceability are key The Smart Dilutor W offers an advanced automation solution to both gravimetric dilutions and liquid dispensing. Adapted to dilute samples both within 400 ml and 80 ml bags, the device can process samples up to 5 g with an accuracy > 99%. ...

It was the first time Flores’s and her fellow researchers used the device, and the measuring procedure resulted to be very successful: “With the FTIR methodology many mistakes in the results due to sample transportation to the laboratory and sample manipulation can be avoided. ...
Upon removal from the oven, the sample was manipulated by the IKA LR 1000—a 20” wide, 30” tall, and 20” deep unit. ...
EPA Toxicity Identification Evaluation (TIE) procedures were modified to account for the tolerance of T.gratilla gametes to various sample manipulations. Microtox rapid toxicity screening was applied in some aspects of the study after verifying a correlation between the pattern of toxic responses of T.gratilla gametes and that of the bioluminescent bacteria ...
In Phase I of a TIE, effluent is subjected to manipulations (see table below) before being retested for residual toxicity. The data are interpreted by comparing the results of the manipulated sample tests to the results of the baseline test, conducted with unaltered effluent. ...

SAMPLE HANDLING OPERATIONS A typical soil sample experiences a number of physical manipulations at the sampling site and in the laboratory. ...
