very standard laboratory thermometer

It is conventional,standard yet versatile.It's no other than this spirit laboratory thermometer. Here is a spirt filled, red alcohol glass laboratory thermometer, which suits your general laboratory use, experiment and testing. This is a 76 mm partial immersion laboratory thermometer and it is designed to be immersed up to the inscribed immersion line.

The markings are black on a white background to make you easy to read the measurements. Laboratory thermometer comes completely with an anti-roll triangle and a case.

VWR* Refrigerator/Freezer Thermometers

With this excellent laboratory thermometer, all students, researcher can monitor temperatures in freezers,refrigerators and other place with its the enclosed “temperature buffered” sensor.The risk of mercury contamination has been reduced by using the Probe which is sealed in a small container with nontoxic glycol liquid that gives accurate readings when doors are opened.


The good abotu this laboratory thermometer is also that you can read the readout simultaneously that shows current, high, and low temperatures. Minimum/maximum display monitors conditions all the time. Refrigerator/freezer laboratory thermometer 61161-364 includes an alarm, which makes sounds if temperature rises above or falls below certain temperature. It is programmable in 1° increments. Visual and audible alarms signal for 12 hours even if temperature returns to non-alarm range.

With a a serial numbered certificate provided by ISO 17025 calibration laboratory accredited by A2LA to indicate instrument traceability to standards provided by the National Institute of Standards and Technology, this will make a good laboratory thermometer for you

safety's first (how to safely use your laboratory thermometer)

Mercury laboratory thermometers, used in some science laboratory, requirer special safety precautions. Alcohol laboratory thermometers, despite of its less dangerous nature, should still be handled carefully to any damage.

Thermometer Safety
You have to twist gently the laboratory thermometer and press it firmly, but don't use brute force when inserting a laboratory thermometer to a rubber stopper. If you could, put a drop of glycerin or other lubricant to make the laboratory thermometer slide more easily.

Considerations
You have to hold your hand with distance of less than 1 inch from the stopper to avoid exerting torque on the thermometer.

Types
Laboratory thermometer safety depends on the type of laboratory thermometer: broken alcohol thermometers and other non-mercurylaboratory thermometers only needs the same cleanup as any other broken glass. A broken mercury thermometer requires special cleaning procedures.

Warning
High school and college students should never try to clean up a mercury spill from a broken mercury laboratory thermometer; instead, tell your laboratory instructor, turn off any heat sources. Trained department staff will come to clean up the spill.

Mercury Spill Cleanup
Personnel responsible for cleaning up a mercury spill, according to Princeton, should wear protective clothing, gloves and goggles, and use index cards to sweep the contaminated material into a sealable jar. Never use a vacuum cleaner or sink. Label the jar, and deliver it to a hazardous waste facility.

how to properly use you laboratory thermometer

Your Laboratory thermometer is capable of doing a highly accurate measurements of temperature variations in a variety of mediums. Since laboratory thermometer has a fragile construction and the price you pay for your laboratory thermometer, you need to get a sense of how to properly use a laboratory thermometer and avoid any damage. With some unworldly equipment and information, you can use a laboratory thermometer without making a costly accident to you and your laboratory thermometer.



1. 


Congeal up the laboratory stand. Most of the laboratory stands are made up of simple design, with a thick metal as its material. You may keep to alter where your stand is positioned, depending upon your experiment. For example, if you are using a Bunsen burner, you may obtain the legs of the stand straddling the burner, but if you are weighing a material as it undergoes temperature change, the stand ' s base can guise away from the scale.


 2


If your laboratory stand has a separated clamp, you'll have to attach the clamp to the stand. The clamp itself has two ends: The top is a rubberized closing that consign hold the laboratory thermometer, and the rest is a C - shaped second with a bar through it. Unscrew the clamp and unite the clamp onto the stand. Tighten the clamp before moving on.


 3


 Put your laboratory thermometer on it. Link the thermometer into the rubberized hindmost of the laboratory stand's clamp. Tighten the screw to secure the laboratory thermometer.


 4
 Place the pole of the thermometer with the tarn of liquor in the testing medium. For example, if you are testing the temperature of harden bedew, place the pool in the wet, unbefitting the refrigerate, but not touching the craft of the flask or cup the soak is held in. This commit garner a additional accurate temperature.


 5
 Interpret the readings. Etched into the thing of the laboratory thermometer are markings indicating degrees in Fahrenheit and / or Celsius. Relevant cyclical markings of degree units leave moreover be present on the thermometer. For instance, if you are measuring in degrees Celsius, every 10 degrees entrust be glaring on the scale, with smaller lines indicating single degrees. Thus, solidify dampen bequeath show up as 0 degrees Cesius, room temperature wet might be 20 or so degrees and spicy freeze irrigate may be as cold as minus - 10 degrees or other.
