Advanced Cleaning: Relationship Between Conductivity, Surface Tension and pH

Q: I am doing a conductivity study using Alconox detergent. I am seeing that the pH and Surface Tension listed on the COA differs between lots. Do you think these variables affect conductivity enough to alter my results?

A: Here’s the short answer… Surface tension does not have any interactive relationship with conductivity; pH has a very small, essentially negligible interaction with conductivity; and concentration and temperature are much bigger causes of change in conductivity.

Dilution Precision in Concentration Measurements

Q. Do I determine detergent dilution by weight or by volume or both?

A. In a laboratory setting, the most common method is to either make a weight/weight dilution (10-20 g Alconox detergent in 990 g of water), or a weight/volume dilution (10-20 g Alconox in 990 mL of water) for 1-2% solutions.  In manufacturing situations, often directions are written volume/volume or volume/weight.

Cannabis Lab

Cleaning Botanical and Cannabis Residue in the Laboratory

Q: We are working with cannabis resin in our lab and the residue is very tough to remove.  We are currently using isopropyl alcohol and it is just not good enough.  Any advice?

A: It is no secret that waxy, sticky cannabis and other botanical resins are some of the most difficult residues to clean.  But of course, keeping your labware, glassware and other laboratory equipment clean is vital.

Ultrasonic Cleaner for Parts and Towels

Q. I’m looking for a cleaning solution to use in our industrial ultrasonic cleaner that is similar to the old style competitor detergent. We use it occasionally for general cleaning, removal of machining oils, cleaning for high vacuum use, and to lightly etch the oxides off of copper.   Would you recommend Alconox or Liquinox detergent?  How long would a pre-mix of the formulations last before degrading?  Could we also use this for washing microfiber towels and foam sponges that have various waxes, polymer sealants and oils on them?

How To Clean Carbide

Q:I was wondering if you have a product that I can use in an ultrasonic cleaner to clean tungsten carbide that would not leach out cobalt? That also can be disposed of down a drain?

A: Tungsten carbide (WC) cleaning comes with some inherent issues, and the cleaning cycle that accompanies it will depend entirely on the feed stock (components to be cleaned) that the process comes from. This is where Alconox, Inc., as the critical cleaning experts, excel from our experience and vast pool of applications to draw upon.

Cleaning Pipettes in the Laboratory

Q. What are some best practices for lab cleaning of pipettes. We’re having trouble in our lab removing dried on residues.
A. The principal concern for any scientist or technician working in the laboratory is that glassware, like pipettes, be free of interfering residues after they are cleaned. Unseen residues can wreak havoc on analytical results by inhibiting culture growth, causing cross contamination, non-reproducible results and more.
