Everything about the lab industry

To meet the ever-growing demand for the lipids and fatty acids, Alfa Chemistry established a subsidiary to specially supply such chemicals. Earlier this month, the company is pleased to announce the release of its fatty acid and ester product line. By now there are hundreds of fatty acid and ester homologs and derivatives readily available for scientists and researchers worldwide. Fatty acid esters (FAEs) are made by dehydrating fatty acids and alkyl alcohol. When the alcohol component is glycerol, the fatty acid esters produced can be monoglycerides, diglycerides, or triglycerides. Dietary fats are chemically triglycerides. “Fatty acids and their derivatives have a wide range of commercial applications. They are a sustainable alternative to petrochemical-based materials and can be used in the formulation of a wide range of consumer and industrial systems. Due to their conditioning effect of softening the skin, FAEs can be added to cosmetics to dissolve high-polarity active ingredients and UV absorbers,” says a spokesman from Alfa Chemistry. In addition, FAEs can also serve as emollients, emulsifiers, plasticizers, mold-release agents, foaming agents for cosmetics, effective wetting agents, pigment dispersants and stabilizers, pearlizing and opacifying agents, moisturizers for winterized and sun-dried skin, waxes, and chemical intermediates. At Alfa Chemistry, a wide range of fatty acid ester homologs and their derivatives are available and can be easily obtained to serve different research and manufacturing purposes. Some of the fatty acids and ester homologs provided are: Pentadecanoic acid, Methyl trans-9-palmitoleate, cis-11,14-Eicosadienoic acid ethyl ester, Methyl 15(Z)-Octadecenoate, 7(Z),10(Z),13(Z)-Nonadecatrienoic acid, Ethyl decanoate, Nonanoic acid, Ethyl tetradecanoate, Methyl 13(Z)-Octadecenoate, Ethyl heptadecanoate, cis-8,11,14-Eicosatrienoic acid methyl ester and more.

For an optimal, homogeneous grinding of the cannabis plant the ideal instrument is the FRITSCH PULVERISETTE 19 – an Universal Cutting Mill for fine grinding and for precise comminution. Cannabis has been used as a medicine in various cultures for thousands of years, for example as marijuana (dried leaves and flowers) or as hashish (the resin of the female plant). Today Tetrahydrocannabinol (THC) and Cannabidiol (CBD) are particularly isolated and researched from the multitude of active substances contained in the plant (in addition to other cannabinoids and terpenes) as pharmacologically effective components. The cannabis active ingredients are used therapeutically in particular • as pain reliever • for appetite stimulation • anti-inflammatory • antispasmodic Supercritical CO2 Extraction The most common method to extract the active ingredients from the cannabis plant is supercritical CO2 extraction. At above 31°C and with high pressure the CO2 gets into the "supercritical" state. It now acts as a solvent. It is passed through a chamber containing the plant material. The CO2 has still the density of a liquid, but can fill the entire chamber like a gas. This is ideal for extraction as it does not cause denaturation or damage to the product. The CO2 extracts the cannabinoids and terpenes from the plant. The result is a safe, high-quality, pure oil, which can now be processed for various therapeutic applications. The producers of these cannabis oils naturally want to make the extraction process as efficient as possible. That means: the highest possible yield of the ingredients in the shortest possible time. Homogeneous grinding of cannabis The requirement for this is an optimal, homogeneous grinding of the cannabis plant. The ideal instrument for this is the FRITSCH PULVERISETTE 19 – an Universal Cutting Mill for fine grinding and for precise comminution. Perfect grinding chamber geometry In cutting mills, the sample is shredded between the knives of the rotor and the counter knives in the grinding chamber using the principle of a pair of scissors to produce the desired final fineness. The unique grinding chamber geometry of the FRITSCH Universal Cutting Mill PULVERISETTE 19 ensures minimal dead space. The progressive cutting geometry between the rotor and stator knives actively transports the sample material. It cannot get stuck anywhere. The special air flow is the basis for quick, clog-free work and quick residue-free cleaning. In addition, the use of the stainless-steel high-performance Cyclone separator ensures high throughput. With the help of an industrial vacuum cleaner and the high-performance Cyclone separator, a negative pressure is generated in the grinding chamber. The material is fed into the FRITSCH PULVERISETTE 19 via a funnel. Different sieve cassettes define the final fineness of the cannabis sample. Unmilled cannabis plant material has a bulk density of 100-125 g/litre, while ground material has a bulk density of 225-250 g/litre. The sample is optimally homogenised by the grinding and significantly more material can be filled into the extraction column. Of course, this also significantly increases the yield per extraction. In cooperation with OutCo, a cannabis producer in California, USA, we examined which degree of grinding means the optimum for the most efficient extraction. The best results are achieved with the 2 mm sieve. Other screens can also be used for different fractions. More PULVERISETTE 19 facts The FRITSCH Universal Cutting Mill PULVERISETTE 19 is also used to grind samples for the potency testing or to examine the material for pesticide residues. In order to optimally adapt the cutting performance to the sample, the speed of the rotor can be regulated between 300 rpm to 3000 rpm. As with all mills used in analytical laboratories, simple cleaning is desirable. The concept of the Clean Design was used for the FRITSCH PULVERISETTE 19: the grinding chamber can be opened completely, all grinding parts can be removed without tools for easy and fast cleaning. Cross contamination can be effectively avoided. The FRITSCH PULVERISETTE 19 is also available in a 316L stainless steel version for use in the pharmaceutical sector.

Alfa Chemistry Testing Lab announces that now one-stop honey and bee products testing solutions are readily available for beekeepers, honey product manufacturers and marketers. Honey is among many peoples’ favorites. The manufacturing of honey products should adhere to strict food regulations to ensure its safety and authenticity before going into the market. “Nowadays people are pursuing healthy food, which contributes to the growing demand for honey and bee products. But in the case of imperfect regulatory mechanisms, adulterated and fake honey are flooding the consumer market. However, according to statistics, honey is very likely to have the highest risk of food fraud. Moreover, honey products can have risk of harmful antibiotics, which is not allowed in food production by regulations. This is because the antibiotics used to treat bees can result in residues in bee products,” says the Marketing Chief of Alfa Chemistry Testing Lab. “We know that residues of antibiotics could potentially cause increased drug resistance and allergic reaction in humans when taken into the body.

Vaisala, a global leader in weather, environmental, and industrial measurements, has today introduced an easy-to-install wireless carbon dioxide measurement solution to simplify incubator monitoring and enable cost savings for customers. The new life science environmental measurement solution combines Vaisala’s carbon dioxide probe GMP251 with Vaisala wireless RFL100 data logger. The new configuration leverages the superior measurement stability and accuracy of the GMP251 probe, and provides reliable carbon dioxide percentage measurements for incubators used for example in cell culturing, gene therapy, and vaccine research. “Traditional carbon dioxide measurement installations take up a lot of space and can be complicated to install and maintain, not to mention the related cost,“ says Product Manager Anniina Uotila of Industrial Measurements, Vaisala. “The RFL100’s CO2 configuration enables a much simpler, wireless setup that is ideal for incubators in both strictly regulated GxP and less regulated non-GxP applications. Wireless data loggers also eliminate the need for expensive Ethernet connectivity for each data logger. Additionally, our incubator customers can benefit from the RFL100’s local display of carbon dioxide data next to their assets.” The RFL100 can provide several measurements in a single data logger: CO2 percentage, temperature, and humidity. Along with the GMP251 carbon dioxide probe, other RFL100 compatible probes include Vaisala’s TMP115 temperature probe, and the HMP115 and HMP110 temperature and relative humidity probes. Power meets performance All RFL100 data loggers connect to Vaisala’s viewLinc software for monitoring, alarms, and reporting. RFL100-series loggers operate on Vaisala’s proprietary LoRa® based VaiNet wireless radio technology with a signal reach of over 100 meters, even in complex, obstructed indoor environments. VaiNet uses LoRa® modulation that prevents signal interference with WLAN applications. To ensure data integrity, all VaiNet data transmissions are encrypted and verified before being stored in viewLinc’s secure database. Vaisala RFL100 data loggers use an external power supply for carbon dioxide measurement and include a lithium battery backup to secure data logger memory during power or network interruptions. "Our customers appreciate VaiNet’s secure wireless connectivity and ease of deployment. Installing Ethernet access for each individual data logger is unnecessary when you have a reliable signal with significant reach, like the RFL100,” Uotila says. “Combined with the GMP251 probes, which provide a wide operating temperature range and high accuracy, the RFL100 data loggers also make probe calibration information available in the viewLinc monitoring system.” In addition to data integrity and global compliance, Vaisala’s award-winning viewLinc Continuous Monitoring System provides user-friendly software, web-based user access, real-time data, and remote alarm capabilities. Deliveries of the Vaisala RFL100 carbon dioxide data loggers will begin in July 2021.
