The Micro TouchPick Pen is the world’s first tool for securely handling and picking up smallest samples without damaging them.

This tool is especially helpful for handling small samples, such as thin films and samples difficult to pick up with tweezers. The unique technique makes the Micro TouchPick pen effective in capturing smaller–sized, fragile particles and samples of all sorts, including biological, archaeological and mineralogical samples.

Accurate sample retrieving and positioning
-    Ideal for fragile & statically charged samples
-    Easy to use for everybody with reduced risk of sample damage
-    Two different sized adhesive tips (0.62 mm and 0.17 mm)
-    Ergonomic pen design with excellent tip visibility
-    Enduring adhesive strengths for long-term usability

Handle all your tiny micro samples with easy with the MICRO TOUCH PICK PEN

Easily adjust & hold all kind of samples with the Micro Vice for analysis with FTIR- and Raman microscopes, stereoscopes & microscopes.

The Micro Vice sample holder provides a unique solution for placing and holding your samples in the desired position under your microscope.
Individually shaped samples, such as minerals, tablets and pills, but also multilayer films, fibers, hair samples can be easily positioned and analyzed in the required position under your microscope.

- Holds round & unevenly shaped samples
-  Holds & stretches fibers, multi-layer films, hairs by user defined increments
-  Permits tilting of oblique samples
-  Facilitates positioning of samples for examination with Microscopes, Stereoscopes, FTIR- and Raman Microscopes
-   Various models available - Fit on most microscope stages

The only sample holder you need for your microscope - the MICRO VICE!

In this short video, Kaziya Lee, Applications Specialist, demonstrates the importance of using an appropriate test solution when optimizing a liquid handler to dispense master mix.

The Artel MVS Multichannel Verification System, PCRMix solution, and a Hamilton STARlet automated liquid handler (ALH) were used for this experiment.

Analytical Cannabis 

Speaking at the Analytical Cannabis Expo East Online 2020 in October, Mike Esposito, Scientist I at MCR Labs presented his talk on microbiological testing of cannabis.

Humans have been enumerating microorganisms since 1878, and in the nearly 150 year history of enumeration, incredible new techniques and technologies have been implemented to both simplify and increase the accuracy of our microbial counting methods. While these techniques range in complexity from counting cells under a microscope to quantifying DNA extracted from a microbe, they all have their own distinct advantages and challenges. In this talk we will take a look at historical strategies, contemporary approaches, and up and coming technologies that we can look forward to. We will discuss shortcomings of traditional methods, like the difficulties of counting dense colonies on a plate and the slow turn-around of test results due to incubations, as well as describing the advantages of these techniques, such as robust validation and decades of implementation that make these techniques the “golden standard”. Additionally, we will look at new technologies like micro-arrays and qPCR that aim to eliminate issues with turnaround time and off-target ennumeration, but come with their own host of issues such as highly variable extraction efficiencies and the rarely discussed topic of copy number variation in some gene targets. Lastly, we will look at adaptations to culture-based and PCR based methods, such as the widely used most probable number technique, and the up and coming droplet digital PCR technology that will look to combine the speed of qPCR with the accuracy of most probable number testing.

Challenges to Microbiological Enumeration

Speaking at the Analytical Cannabis Expo East Online 2020 in October, Josh Smith, CEO & Chief Scientist at Premium CBD Labs, presented his talk on microbial testing of cannabis.

Microbial Testing requirements vary in the US from state to state and the type of cannabis your crop or product is derived from. From overly generic such as “total aerobic” to using DNA based methods to test for E. coli O157:H7 and even all the way to …. nothing at all. Why do these tests matter, what do they actually tell you and how did the states decide on them? In the end, do they make sense? When a major problem with the cannabis industry is a resurgence of the black market and compliance costs for legal products, it’s worth reviewing these kinds of requirements and asking if we have picked the right monitoring tests to make these products safe for consumption.

CRISPR is revolutionizing the field of genetic editing. By providing scientists with powerful tools to change any gene in any cells in a highly targeted manner without introducing foreign DNA, it has the potential to alter the process of biomedicine research and drug discovery. Compared with traditional methods, CRISPR is easy to implement and performing balletic genetic modification more efficiently. Using CRISPR/Cas9 technology, we can disable target genes by introducing frameshift mutations or removing large fragments of the gene.
