Hettich Instruments
Hettich instrument recognized as one of the top clinical & research centrifuge manufacturers in the world, Andreas Hettich GmbH & Co.KG (Hettich Centrifuges) continues to be a leader in centrifugation technology, innovation and safety. For more than 100 years, our centrifuges have served many applications in the blood bank, clinical laboratory and research laboratory in hospitals, universities and government agencies. In addition, Hettich centrifuges are utilized in a variety of applications in the Pharmaceutical, Food & Beverage and Environmental markets.
Centrifuges make use of the centrifugal force that acts on mixtures during rotational movement to separate the constituents. A pre-requirement here is a sufficient difference in density between those constituents. Laboratory centrifuges are sedimentation centrifuges and may take the form of benchtop or floor-standing models. They are used in many fields, such as chemistry, physics, pharmacy, biology, biotechnology and, not least, medicine. Their power is needed in industry for production purposes, in research facilities for scientific applications and in medical laboratories for investigation purposes or to derive blood constituents.
Hettich offers a full range of products from small benchtop centrifuges to large floor standing models including robotic units for easy integration into laboratory automation systems.
Hettich Instruments located in Beverly, Massachusetts, provides full service and support for North America. Family owned and operated, we believe in connecting with our customers to provide application assistance, product knowledge and efficient product delivery.
The powerful, microprocessor-controlled benchtop centrifuges with a wide range of accessories allow you to carry out virtually any centrifuging task. Max. RPM (speed): 15.000 min-1, max. RCF: 21.382. Extreme user-friendliness is provided by the easily comprehensible control panel, select key to choose the parameter, twist knob to enter the values, open lid key, powered lid locking, lid holding, and 10 programmable memories. Temperature in the refrigerated UNIVERSAL 320R is controllable within a range of -20 to +40 °C. The UNIVERSAL 320R also features a Fast Cool function. The stand-by mode maintains the set temperature.

Whatman Nytran™ nylon membranes are available in two formats. The Nytran N is moderately charged and the Nytran SuPerCharge (SPC) has a very high positive charge.
Nytran nylon
The Whatman Nytran nylon membrane is suitable for applications that require a lower charge. It is designed for Southern and Northern blotting as well as colony and plaque lifts and Dot-/Slot-Blots. Nytran N is compatible with isotopic and nonisotopic detection methods.
Nytran N membrane allows for excellent signal-to-noise ratios. The membrane is cast uniformly on both sides of a support matrix, demonstrating excellent symmetry. This gives the membrane the ability to lie flat without curling. Nytran N membrane is a highly consistent membrane with uniform pore size and distribution.It is available in 0.2 µm and 0.45 µm pore sizes for optimal retention of oligos and larger DNA fragments.
Nytran SuPerCharge (SPC)
Nytran SPC nylon membranes have a very high positive charge. Improvements in the manufacturing process result in a membrane with a higher density of nylon per unit area. The increased charge and greater nylon density provide increased binding sites for your samples.
Nytran SPC membranes show a very uniform pore size and pore distribution compared to typical nylon membranes. They are free of surface microvoids which are common in other membranes. These characteristics lead to greater reproducibility of results across a membrane and from blot to blot.
Nytran SPC membrane is cast uniformly on both sides of a support matrix, demonstrating excellent symmetry. This gives the membrane the ability to lie flat without curling.
With typical manufacturing techniques, increasing positive charge tends to increase background. Nytran SPC membranes are manufactured using a process that allows the combination of high positive charge with low background. Whether using radioactive or nonradioactive detection techniques, Nytran SPC consistently gives high signal with extremely low background.
Nytran binding capacity: > 400 µg/cm2; Nytran SuPerCharge: > 600 µg/cm2

Whatman Westran PVDF Membranes
Whatman Westran™ PVDF (Polyvinylidine Fluoride) membranes are available in two formats: the Westran S used for protein sequencing and the Westran Clear Signal used for Western blotting
Westran S
Westran S PVDF is a 0.2 µm pore size hydrophobic membrane designed specifically for protein sequencing applications. The small pore size of this membrane eliminates ‘blow-through’ and increases protein binding over a wide range of molecular weights.
Features and benefits
- Protein binding capacity (over 200 µg/cm2) for easy signal detection
- Chemical resistance needed for N-terminal sequencing
- High protein retention even after harsh wash steps
- Maximum capture of proteins during transfers minimizing sample loss
- 0.2 µm pore size for higher surface area, resulting in better binding of low molecular weight proteins
- Compatible for use with Western blotting applications
- Available in popular precut sizes for your application
Westran clear signal
Westran Clear Signal (CS) PVDF is a 0.45 µm membrane specifically designed for Western blotting and protein dot-blotting applications.
Features and benefits
- Protein binding capacity over 125 µg/cm2
- Extremely low backgrounds with chemiluminescent and colorimetric applications providing you with clear signals and sharp bands
- Excellent results with general protein stains such as Coomassie® Brilliant Blue, Amido Black, and Ponceau S Red
- Increased strength allows for multiple stripping and reprobing, which results in savings
Westran blotting sandwiches
A precut PVDF membrane and 2 sheets of 3MM Chr blotting paper are prepackaged into a sandwich to help save time. Sandwiches are available with either Westran S or CS.
