Fischer Technical’s new PILOT series Diaphragm Chemical-Resistant Vacuum Pumps

For quite some time we have been selling Fischer Technical’s excellent High-Vacuum Pumps , an excellent line that is incredibly durable – able to handle operating 24/7. But these pumps are oil based and do require oil-changes.

Now Fischer has added a new line of Diaphgram vacuum pumps to fill the needs where a pump is required, but not the endurance of the high vacuum pumps, but still providing decent vacuum production as well as being chemically-resistant for use in the lab.

Enter the PILOT3000 and PILOT5000, both excellent choices for for a laboratory’s filtration, dessication and other mid-range needs. The PILOT series include features such as an inlet trap & vacuum regulator and all contact surfaces are PTFE (teflon) coated for chemical resistance, making them virtually maintenance-free.

Both the PILOT3000 & PILOT5000 are 20psi continuous-duty pump, both operate at a low-volume ~54dB range, are small (both models under 9″ in their longest dimension), lightweight (7.5 and 13 lbs respectively) and durably built in the USA. Both units can use an optional Vacuum Regulator Assembly, to keep the level of pressure you require.  The chemical-resistance is able to handle acetone vapors and bleach, allowing them to be used with cell-culture decontamination protocols.

The PILOT3000 and PILOT5000 are economically priced, costing $414.24 and $669.22 respectively. The PILOT5000 also has the available option of operating on 230V (opposed to the standard 115V) in both European and Amercian versions.

Bother of these models are excellent options for multiple markets. Get yours today!

The New AAS T-heater Slim PCR Cycler

In Biotechnology there is a process known as PCR. PCR, or Polumerase Chain Reaction is widely performed through a series of heating cycles that pull apart, duplicate, and fuse back together the two strands of a DNA double helix, PCR creates new copies of DNA that are identical to the original.

Traditional PCR requires the material be heated to about 95C, wherupon the DNA strands seperate, or ‘denature’. The sample is then cooled a bit  so the strands will anneal to ‘primers’, which are short DNA strands designed to bond to specific sections of the DNA strand. The sample is heated slightly more (72C) and  activates an enzyme called polymerase that attaches itself to the end of the primer. The polymerase “extends” the primer’s length based on the original DNA, thus recreating the desired sequence.

During this “extension” step, the polymerase reacts with the original copy to produce a new chain of DNA, thus the name Polymerase Chain Reaction. Since this process happens for both of the original DNA strands, the amount of DNA is doubled after one PCR cycle. Over many cycles, PCR exponentially expands the amount of DNA you were started with.


Accuris Instruments Aspire Laboratory Aspirator

Accuris Instruments is a new company – mind you it is actually a division of Benchmark Instruments but it is entering the market with a bang – new measuring instruments will be introduced over the next month. First up from from them is the Aspire Laboratory Aspirator:
