Do you have an old C-series centrifugal pump and are not sure what size it is for replacement or parts? Just measure the backplate!
• 4″ backplate is a C114.
• 6″ is a C216.
• 8″ is a C218/328.
• 10″ is a 4410.
The frame size and horsepower of the motor will be the other information that you will need if you want a replacement pump quoted.

Recently, many production facilities and states are banning the use of mercury thermometers within their labs making the spirit-filled units more popular. Many times when these thermometers are shipped they do separate within transit.
The most commonly used method to re-join the liquid is to gently tap the thermometer above the separation point in an upright position.
Should this not work here is another little trick. Boil water and place the thermometer in the boiling water, flip it upside down to remove any air bubbles that may have formed, then reinsert it vertically into the boiling water and your organic material should be rejoined.
Lastly, to avoid separation always store your spirit-filled thermometers in an upright position.

Many pH electrodes are shipped with the electrodes moist. Prior to using your electrode for the first time it needs to be conditioned. While it is always best to refer to the manufacturer instructions for proper electrode conditioning, below are three common recommended steps for conditioning your electrode:
1. Remove the protective cap or bottle from the bottom of the sensor and rinse the electrode with distilled or deionized water and blot with a Kimwipe.
2. Place the electrode in a beaker containing one of the liquids listed below (in order of ionic ability to condition the electrode.) Soak for 20 minutes.
• 3.0 M KCI
• 4.0 pH buffer
• 7.0 pH buffer
Note: Never condition or store a pH electrode in water – long term exposure to purified water will damage the special glass membrane.
3. After conditioning the sensor for 20 minutes, rinse the electrode with distilled or deionized water and blot with a Kimwipe. The electrode is now ready for calibration and to measure pH.

Every day, employees are subjected to loud noises at their workplace. It is up to the employer to supply appropriate hearing protection and implement a hearing protection program if noise levels exceed 85 decibels measured with a Time Weighted Average (TWA.)
The hearing protection used will vary greatly depending on the environment, noise levels and personal preference. It is necessary to offer options that all meet your company’s program requirements.
Basic hearing protection can be broken down into three choices: earplugs, semi-aural, and earmuffs.
Earplugs are placed inside the ear canal, and there are two options: Disposable or reusable, and both come in either corded or uncorded versions.
Semi-aural protection is a banded product that can easily be taken off and on. It caps off the ear canal and typically offers a lower protection level than plugs.
Ear muffs are available in many options that involve cushions that fit over the entire ear.
When it comes down to it, it is the employer’s responsibility to supply the hearing protection and your employee’s responsibility to wear it. For more information on Noise Reduction Ratings, see our Learning Center. To view our selection of hearing protection, visit our website.
There are many options when looking at the bristles in your brooms – material, stiffness, color, etc. One option is a flagged or unflagged bristle.
The ends of flagged bristles look like split hairs – these bristles are ideal for sweeping up fine powders or debris in dry areas. When used in wet applications it is common for these bristles to become “matted-up” and dirty.
Unflagged bristles are commonly used in wet applications, and are ideal for larger debris. They will not, however, sweep up the fine debris as effectively as a flagged bristle will.
Both flagged and unflagged brooms have their applications within many facilities. Choosing the correct one can make your clean-up job easier.
