Cell volume lab

Method and Materials:We calibrated the conduction sensor by mensuration the conductivity when distilled peeing and 1.1% NaCl (338mOsm/kg) is added. We made sure enough that the conductivity essay powerful given to the right insert on the SW500 embrasure which is committed to the computer. We took sm solely beaker to the movement of the room and we commute it ¾ full with the disposed(p) solution. We heart-to-heart ?Lab Group? folder. We and so opened ? testing ground 2? folder. We clicked on the sensor. We accordingly(prenominal) opened the standardisation segment of the program. We rigid the conductivity probe first into distilled pissing and consequently we press ?take entering?. We inserted the submerging of distilled water in the table as 0mosm. We opened the program for laboratory 2. We placed the probe in unitary of the 12 solutions. We started written text by activating the start button. We continued recording until the depictings be durable then w e clicked the ?stop? button. We habitd the ?smart tool? to read the condutivity care for and then we entered the data in the table. We removed the conductivity sensor from the beaker and then we shaked the sensor off. We made similar measurements of the relievo 12 NaCl solutions, and then we entered the data into the data table in the row labeled conductivity. We saved the data file in our own group data folder. Next, we determined the osmolality of for each one of the 12 solutionsWe prepared test solutions; we used red smirch pencil to label the 12 test thermionic valves from 1 to 11. We marked the eventually test render-shaped structure with a letter ?C? refers to Control. From the front of the room, we placed 5 ml of 0% NaCl in the influence tube. We then placed 5 ml ranging in concentration from 0.1-1.1% NaCl into the other 11 tubes utilise pipettorWe Used the Eppendorf micropipet provided to add 20 l of blood to the tube. We attached the cap onto each tube and then mixed gently. We placed the circular test t! ube rack holding the 12 tubes into the provided water bath at 37OC for 30 proceeding. We mixed the tubes gently after incubation and then centrifuge the tubes for 5 minutes at 3000 RPM. We turned on the colorimeter; we next fill one of the cuvettes with distilled water to manage as fictitious character.

We pressed the ?Select? and ? conk/Stop? buttons at the same time. We inserted the name cuvette and then pressed ?Select?. We waited until it verbalize ?CAL done?. We then opened the lid and removed the reference cuvette. We pressed ?Start? and began measuringWe transferred the solution gently using pipette from t he top of the ?C into a clean rectangular cuvette so it is filled to within 0.5 cm from the top; we made sure to use a unexampled pipette and a clean cuvette for each test tube measurement . We placed the cuvette into the Colorimeter and unappealing the lid. We read the %T (% Transmittance) value of the ?Control? tube and then recorded the value in the table. We left the Colorimeter lead to measure the %T value for cuvettes 1-10. After completing all measurements, we made sure to turn off the Colorimeter.
