Analysis of Aqueous Mobile Phase Sample Preparation and Filtration Steps in Cannabis Analytical Testing

The two-fold objective of this study was to 1) demonstrate that aqueous mobile phase preparations from purchased lab grade bottled water yielded comparable results to in-house prepared water (Sartorius Arium purified water Type 1 and Type 3) and that 2) using filters (Sartorius Minisart RC, SRP, NY & NY Plus, all 0.2 µm) yielded comparable results to unfiltered specimens under the same mobile phase conditions.

Practical Selection Guide: Practical Tips for Choosing the Bottle-top Dispenser for Your Lab

Bottle-top dispensers are common tools found in various laboratories. They are used to safely dispense a set amount of liquid, ususally between 1 and 60 ml, from a  bottle or a container to a receiving container. There are differences to consider, between makes and models, when chossing the most suitable one. Keep in mind: If your Cannabis testing procedure requires you to repeatedly portion out exact volumes of liquids involved, our bottle-top dispensers will give you a steady hand to ensure accurate and consistent results. Get to kow the points to consider for a bottle-top dispenser here.

Cannabis Testing: In-House Prepared Water as an Alternative to Bottled HPLC-Grade Water

In many testing laboratories, bottled HPLC-grade water is the standard when performing quantitative potency analysis for cannabinoids like THC (Tetrahydrocannabinol) or CBD (Cannabidiol). In-house produced water, on the other hand, may be qualitatively equivalent and also a more cost-effective alternative.

Chemical Resistance Chart of Pipette Tips

The chemical resistance is based on information provided by the manufacturer of the raw material. This table os for a general guidace amd does not guarantee the performance. The chemical resistance can be affected by concentration, temperature and lenght of exposure. The polyproylene (PP) products, including trays, racks and non-filtered tips are resistant to conditions used in standard autoclaving procedure: 121°C, 20 min, 1 bar/100 kPa.

Claristep Filtration System App Note 

We tested the novel filter device Claristep® for the preparation of protein samples containing one of four different target molecules: an anti-malaria vaccine candidate, aviscuminum, interferon alfa-2B, or monoclonal antibody (mAb) P2G12. In comparison to the standard protocols for sample preparation prior to analysis by either reversed-phase or SEC HPLC, the Claristep® filter did not exhibit a significant difference in protein concentration if the target molecules were present with at least 1.0 g L-1. A significantly reduced product concentration was observed in the Claristep® filtered samples compared to the standard protocol for mAb P2G12 if the concentrations were lower. The protein adsorption to the filter material was well described by a Langmuir adsorption isotherm. Additionally, the Claristep® filters facilitated a rapid sample preparation with minimal volume losses.

Practical Selection Guide: How to Select a Mechanical Pipette

Widely used in laboratories of all kind, mechanical pipettes are long-lasting tools. Because they are used several hours a day, ergonomics and personal references - such as handling comfort - are important selection criteria.  Other factors such as the applications, the laboratory workflow, required volume ranges, physical properties of the sample, and requirements for accuracy and precision also need to be considered when searching for the right pipette for the job.

Performance Comparison of Low Retention Pipette Tips From Various Manufacturers

Pipetting accuracy and precision are the key factors for successful experiments in the laboratory. The best pipetting performance is achieved, when the pipette and tip match perfectly with each other, and the tip being used is optimal for the liquid being transferred. This application note describes the comparison of various manufacturers' low retention tips, when handling liquids that can contain detergents. The results show that Sartorius Low Retention Tips ensure near complete recovery of the sample, when pipetting liquids of low surface tension. They secured also the best sample recovery amd the best chemical resistance.

How to Avoid Contamination in Pipetting

Preventing contamination in pipetting is paramount to achieving reliable results. It requires identification of the potential contamination mechanism in order that they can all be addressed. This paper addresses the three contamination types that originate from pipetting: Pipette-to-sample contamination, sample-to-pipette contamination, and sample-to-sample contamination. Keep in  mind: If your testing procedure in your Cannabis environment  requires you to repeatedly portion out exact volumes of liquids involved, our bottle-top dispensers will give you a steady hand to ensure accurate and consistent results.

How to ensure your lab has the highest quality water for your experiments - More than just H20 - Water Quality in the Laboratory

Water is essential to life-sciences research, but for many scientists, the most thought given to this ubiquitious reagent is "how much of it do I need?" Because water is capable of acting as a solvent to many substances and capable of sustaining life, it can be easily contaminated. Even within a single laboratory, the water used in one experiment can differ from that used in another.
