| Question | Answer |
|---|---|
| Facilitate the correct performance of analytic procedures with accurate and precise information | CC |
| Scales of Thermometer - | Celsius, F, Kelvin |
| Types of Thermometer | Thermistor Probe, Liquid in glass |
| Pipettes are used to transfer what ml of liquids? | <20mL |
| Pippetes according to DESIGN- | TC, TD |
| AKA: Rinse-out pipettes Calibration medium: Mercury | TC |
| Designed to drain by gravity Calibration medium: Distilled water | TD |
| In order TO CONTAIN, RINSE-OUT the MERCURY In order TO DELIVER, DRAIN the DISTILLED WATER by GRAVITY | NICE TO KNOW |
| Pippetes, according to DRAINAGE | Blowout, Self-draining |
| With etched rings located near the top Last drop should be blown out to obtain the exact volume of the liquid | Blowout |
| Has no etched rings. Designed to drain liquid by gravity Tip of the pipette should not be in contact with accumulating fluid in the receiving vessel during drainage Ex: Mohr pipette | Self-draining |
| Pippetes according to TYPE | Measuring/Graduated , Transfer |
| Measuring/Graduted Pipettes ex: (SMBB) | RBC pipette, WBC pipette, serological pipette, Mohr pipette, Sahli pipette |
| Transfer Pipettes ex (VOPAM) | Automated pipette, Pasteur pipette, Ostwald & Folin pipette, volumetric pipette |
| Any substance used to produce a chemical reaction | REAGENT |
| Most commonly used REAGENT WATER | Purified Water |
| Water purified by distillation | Distilled Water |
| Water purified by ion exchange | Deionized Water |
| Water purified by reverse osmosis | Ro Water |
| Ultrafiltration, Ultraviolet light, Sterilization or ozone treatment | Other purification methods |
| LEVELS OF WATER PURITY | Type I, II, III |
| Most pure WATER PURITY - For preparation of standard solutions, buffers, and controls | Type I |
| TYPE I WATER ex (TEQH) | Electrophoresis, Toxicology screening tests, Quantitative procedures, High-performance chromatography |
| For qualitative chemistry procedures and most procedures done in hematology, immunology, microbiology, and other clinical test areas - what reagent type | II |
| For some qualitative laboratory tests, such as those done in general urinalysis Used as a water source for preparation of type I or type II - what reagent type | III |
| Used for washing and rinsing laboratory glassware | III |
