Cell volume lab

Method and Materials:We calibrated the conduction sensor by mensuration the conductivity when distilled weewee and 1.1% NaCl (338mOsm/kg) is added. We made accredited that the conductivity see powerful inclined to the right insert on the SW500 porthole which is committed to the computer. We took sm solely beaker to the movement of the room and we alter it ¾ full with the disposed(p) solution. We subject ?Lab Group? folder. We and so opened ? testing ground 2? folder. We clicked on the sensor. We accordingly(prenominal) opened the standardization segment of the program. We place the conductivity probe first into distilled piss and because we press ?take entering?. We inserted the submerging of distilled water in the table as 0mosm. We opened the program for research laboratory 2. We placed the probe in unrivalled of the 12 solutions. We started save by activating the start button. We continued recording until the take aimings argon durable then we clicked th e ?stop? button. We habitd the ?smart tool? to read the condutivity nurture 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 equilibrium 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 piping-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 use 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 quietl y. We placed the circular test tube rack hol! ding the 12 tubes into the provided water bath at 37OC for 30 transactions. 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 up one of the cuvettes with distilled water to manage as fictitious character.

We pressed the ?Select? and ? bugger off/Stop? buttons at the same time. We inserted the refer 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 the 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 sore 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.
