Insert one end of the red straw into the lubricant spray nozzle. Lubricate the dispenser by inserting the other end of the red straw into the tip of the dispenser and apply a quick squirt of aerosol CRC-56. Only a small amount is required. Wipe excess lubricant from the LeadCare II Blood Lead Test Kit NOT - UNIQUEmix the blood before filling the capillary tube. Make sure the blood sample does not contain clots Blood clots can lead to erroneous blood lead results. Use the capillary tube and plunger provided with the test kit to remove 50 µl of blood from the collection tube and dispense it into the treatment RECAUTIONS Mel-Temp Apparatus1 Make sure a thermometer is inserted into the Mel-Temp. If not, place the bulb end of a thermometer (with an upper temperature of at least 250 oC) in the opening. 2. Turn on the apparatus using the on/off switch 3. Insert melting point capillary tube into the holder 4.

Melting Point Apparatus - Chemistry/Biochem Technology

Most elements and compounds have a specific temperature at which it melts. Small amounts of whatever is tested is inserted into small, thin tubes and inserted into the machine. A magnification tool is attached to the machine to closely observe the material in the tubes. The machine can then heat the tube and material at a predetermined temperature.

Capillary Tubes . We use 1.0mm and 1.7mm O.D. tubes from Wilmad. The capillary action (with a little help) is always sufficient to draw the solution into the tube. Normally, aliquot ~30uL of solution into a small Eppendorf tube, dip the capillary in, and tip or invert the whole setup if the solution does not completely go into the capillary. ORGANIC LABORATORY TECHNIQUES 4 - Chemistryabove). Insert the thermometer into the thermometer well and the capillary into the channels located on the front of the thermometer tube (there are slots for three capillaries). Turn the green LED power switch on (the "1" position) and turn the black heating control knob in order to set the power level to Recrystallization IntroductionFirst a finely powered compound is packed into a melting point capillary tube to a depth of 1-2 mm. Then the capillary tube containing the sample compound is inserted into one of several devices used to measure melting points. Figure 3(a) shows the Thiele tube apparatus, filled to the base of the neck with silicone oil or mineral oil.

tube. The thermometer and capillary tube must not touch the Thiele tube (see Fig. 1). (If your clamp will not hold your thermometer, you can attach the thermometer adapter and clamp to the rubber piece of that. Safety tip Be sure to lubricate the top of the thermometer with a small amount of stopcock grease before attempting to slide the inserted small amount of product into 1 capillary tube by i-STAT Crea Cartridge - zoetisUS(capillary tube, pipette, or dispensing tip) into the sample well of the cartridge. 4. Slowly dispense sample into the sample well unt il the sample reaches the fill mark indicated on the cartridge. Cartridge is properly filled when the sample reac hes the fill to mark and a small amount preproom - The Workshop - Basic ThermometerFig 3 shows the capillary tube which has been inserted into the lid hole. Adjust this so that when the lid is placed on the can, the bottom of the tube sits about half way into the can. Use a glue gun to attach the tube to the lid, ensuring there are no gaps where air could get in. Glue each side and allow to cool.
