How to Safely Use Acetone Cleaner in an Ultrasonic Bath

PubChem, an open chemistry database at the National Institutes of Health (NIH), defines acetone as a colorless, volatile, flammable organic solvent.  It is also called dimethyl ketone, 2-propanone, and beta-ketopropane.  As a low flash point solvent, acetone cleaner is widely used in manufacturing as a highly effective degreaser for residue-free removal of contaminants in an ultrasonic bath. 

Key cautions or “red alerts” for using an acetone cleaner include low flash point, volatility and flammability. This is why special precautions are required to safely use acetone cleaner in an ultrasonic bath to avoid potential fire and an explosion.  Here we describe equipment and procedures to follow when using acetone cleaner in an ultrasonic bath.… Read the rest

Medical Ultrasonic Cleaner Performance Validation


In its “Guideline for Disinfection and Sterilization in Healthcare Facilities” the CDC notes “Ultrasonic cleaning removes soil by cavitation and implosion in which waves of acoustic energy are propagated in aqueous solutions to disrupt the bonds that hold particulate matter to surfaces.”

Sub-par performance of a medical ultrasonic cleaner could lead to trouble.  That’s because a number of factors can compromise the efficiency of these cleaners, leaving contaminants that might not be revealed by visual examination.   This is especially relevant when medical instruments and labware have complex, difficult-to clean configurations.  OK-Sonic™ medical ultrasonic cleaner performance validation strips provide added assurance that your ultrasonic cleaner is doing its job. … Read the rest

Choosing and Using an Ultrasonic Cleaner for Carburetors

Use an Ultrasonic Cleaner to Restore Carburetors

Fuel injection systems have replaced the carburetor but a Gili’s Automotive post states “While carburetors may not have a life in new vehicles today, chances are good that they’ll still be used for many years to come.”  That’s because “Carburetors, unlike fuel injection systems, are relatively straightforward when it comes to repairing them. Fuel injection requires sophisticated computers, but carburetors require only a screwdriver and a willingness to get one’s hands dirty.” Keeping carburetors clean is easy with an ultrasonic cleaner.

This post explains to shade tree and professional mechanics why ultrasonic cleaners for carburetors keep these vital assemblies (which were invented by Karl Benz in 1885) functioning. … Read the rest

At this posting Phase 3 clinical trials are underway for COVID-19 vaccines, some of which call for an ultra-low freezer for storage and transport.  Examples described in a September Wall Street Journal article notes the unusually cold storage temperatures – as low as -80⁰C – required. Covid-19 vaccine candidates are one of many applications for ultra-low freezers.  This post provides you with info on when and how to specify one of these units. 

Unlike “ordinary” freezers, ultra-low freezers are not inexpensive.  The investment is important when the job is to  protect contents of high value and sometimes for long periods of time.  More on this below.

Fortunately there are a number of ultra-low freezers on the market to ease the selection of a model that best suits your needs.

How to Select an Eco-Friendly Ultrasonic Parts Cleaner

How to Develop an Eco-Friendly Metal Parts Cleaning System

Challenges relating to cleaning new or refurbished parts, many of which require subsequent processing such as painting and plating, are increasing due to environmental regulations.  This post shows you why an ultrasonic parts cleaner using eco-friendly biodegradable parts cleaning solutions is a favored alternate to washing and spraying with harsh solvents along with their associated disposal concerns.   

Why Choose an Ultrasonic Parts Cleaner?

Let’s start with why you should consider an ultrasonic parts cleaner.

Cleaning is faster, safer and easier when using an ultrasonic parts cleaner.  Machining oils, grease, residues left from molding or handling, soot and other contamination are difficult and can be dangerous to remove by soaking in harsh and sometimes flammable solvents, manually scrubbing or power washing in solvent parts washers. 

Moreover these methods do not reach difficult-to-access surfaces such as cracks, crevices, small diameter and blind holes where contaminants remain and can cause future problems.… Read the rest

Low-Temperature and Ultra-Low Temperature Freezers for Covid-19 Vaccines

Low-Temperature and Ultra-Low Temperature Freezers for Covid-19 Vaccines

A question posed in the September 5-6, 2020, Wall Street Journal asks “do we have enough freezers?”  This relates to the unusually cold storage temperatures – as low as -80⁰C – recommended by certain producers of Covid-19 vaccine candidates in Phase 3 clinical trials.

Proper vaccine storage temperatures have always been a concern as evidenced by the CDC’s continually updating its Vaccine Storage and Handling Toolkit.  The Toolkit details stringent recommendations relating to critical considerations such as staffing and training for safe handling, storage and temperature monitoring, inventory management, transport, and emergency vaccine and storage handling.

Earlier, MarketWatch identified Moderna, BioNTech and Pfizer as examples of Covid-19 candidates requiring low temperatures (-20⁰C Moderna) and -70⁰C (BioNTech and Pfizer).   Other candidates are J&J Janssen and AstraZenca at between 0⁰ and -10⁰C.  In total, some 9 firms have advanced to Phase 3 trials as reported in a Wall Street Journal September Read the rest

Guide to CDC Recommended Laboratory and Medical Refrigerators and Freezers for Vaccine Storage

Vaccine Storage

CDC Recommendations for Approved Laboratory, Medical, and Biomedical Refrigerators and Freezers for Vaccine Storage

Maintaining a cold chain through-out the entire vaccine supply chain is critical to the safety and security of vaccines. According to the CDC, the cold chain begins with the cold storage unit at the manufacturing plant, extends to the transport and delivery of the vaccine and proper storage at the provider facility, and ends with the  administration of the vaccine to the patient.

Additionally, the CDC stresses in its Vaccine Storage and Handling Pink Book that manufacturers, distributors, public health staff, and health care providers share responsibility to ensure the vaccine cold chain is maintained from the time vaccines are manufactured until they are administered.

To ensure safe vaccine storage, medical grade laboratory, pharmacy, and biomedical refrigerators and freezers must comply with … Read the rest

Sonicator Baths for Sample Prep

How to Use a Sonicator Bath for Sample Prep in Pharmaceutical Research

Sample preparation is defined by the International Union of Pure and Applied Chemistry (IUPAC) as the process used to transform analytes into a measurable form.  Several terms are used to describe the equipment used for sample prep, among which are sonicator baths.

For example, in Sample Preparation of Pharmaceutical Dosage Forms, “sonicators, also referred to as ultrasonic extraction, can be considered both particle size reduction techniques and an agitation technique.  Because of its ability to disperse, mix and dissolve samples, it is widely used in the sample preparation of dosage forms.”

Sonicator baths, sonicators and ultrasonic cleaners are terms describing equipment commonly employed in drug design and development. Because the term “ultrasonic cleaner” is a bit misleading in this context (normally associated with thorough cleaning of parts) we’ll use sonicator bath in this post.

The Purpose of Sonicators
