Benchkote ® and Benchkote Plus ™
20% off until 31st Oct 2007

Benchkote
Benchkote is an absorbent, impermeable material designed to protect laboratory surfaces against hazardous spills.

The material features a high quality, smooth, absorbent Whatman paper which quickly absorbs liquid spills and a laminated polyethylene layer that prevents flow through to the working surface.

After use the sheet is incinerated or disposed of according to local regulations.

This makes both Benchkote and Benchkote Plus excellent products that comply with OSHA Regulation 29CFR 1910.1030 for Occupational Exposure to Bloodborne Pathogens.

Benchkote Plus
Benchkote Plus is a thicker, more absorbent material for more demanding applications and can absorb in excess of 0.75 litres of water per square meter.

Features and Benefits
-       Material is very strong, making it tear resistant, wet or dry
-       Smooth white surface can be written on with ink or pencil and lies flat
-       Suitable for saturation with disinfectant to protect benches where pathogens and other       bacteria are present
-       Use polyethylene side up to collect deposits without absorption
-       Paper side quickly absorbs liquids preventing liquids from going through to the working       surface
-       Spillages are trapped in the absorbent paper
-       Benchkote can be picked up and burnt very easily after use; the polyethylene layer does       not melt or drip but is rapidly consumed in the flames

Applications
-       Containing radiochemical spillage and avoiding contamination
-       Recovering spillage of expensive materials
-       Protecting hard surfaces to lessen impact
-       Water or solvent wick for humidity chambers
-       Lining of chemical cabinets, laboratory bench drawers and laboratory hoods

Whatman Mini-UniPrep™ Syringeless Filters

Simple, Innovative, Convenient
The Whatman Mini-UniPrep Syringeless Filters, now with a new durable plastic cap, provide a faster, easier way to remove particulates from samples being prepared for High Performance Liquid Chromatography (HPLC) analysis. In fact, Mini-UniPrep lets you prepare samples in one third the time required by other methods. Add up the time savings, plus the money saved from cutting multiple consumables out of the sample preparation process and you'll see huge benefits for your lab.

Mini-UniPrep Automated

Mini-UniPrep is a pre-assembled filtration device consisting of a 0.4ml capacity chamber and a plunger. The plunger contains a filtration membrane at one end and a pre-attached cap/septum at the other. The plunger is pressed through the sample in the outer chamber and positive pressure forces the filtrate into the reservoir of the plunger. Air escapes through the vent hole until the locking ring is engaged providing an air-tight seal. Within seconds the Mini-Uniprep can be placed into any approved autosampler for injection into your instrument.

Six Position Compressor

The device can be used either manually or with one of the compressor units available. The new multi compressor can process up to 6 samples at one time, further improving sample processing time and reducing the risk of hand stress. The Mini-UniPrep device is designed to fit into any autosampler designed to accommodate 12 x 32mm vials. Alternatively the septum can be pierced with a needle and the sample drawn off for manual injection into an analyzer.

Features and Benefits
-       All-in-one filtration process allows to process sample loads in one-third the time
-       Wide range of membrane choices from 0.2 and 0.45µm pore sizes to meet specific sample       application requirements
-       Compatible with most major autosamplers. Allows for speeding processes
-       Fewer consumables required. Lower costs by up to 40 percent.

Applications
-       Routine analysis
-       Composite assays
-       Content uniformity
-       Protein precipitation
-       Solubility testing
-       Dissolution testing
-       Sample filtration

Whatman GD/X Syringe Filters

Whatman GD/X disposable syringe filters are the ideal choice for the preparation of hard-to-filter samples. The syringe filters have a pigment-free polypropylene housing to eliminate sample contamination and contain a unique prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfibre media, which allows you to filter even the most difficult samples with less hand pressure. Compared to an unprotected membrane, GD/X syringe filters can process three to seven times more sample volume.

GMF 150 (graded density) and GF/F are produced from 100% borosilicate glass microfibre. The unique, graded density GMF 150 medium has a coarse top layer meshed with a fine layer beneath that retains particles to 1.0 µm. A GF/F filter then retains particles down to 0.7 µm. Below the prefilter stack is the final membrane.

This provides exceptionally good loading capacity with fast flow rates and avoids the build up of back pressure often experienced through "blocking" of an unprotected membrane.

Features and Benefits
-       13 mm and 25 mm diameter syringe filters
-       13 mm device for samples up to 10 mL and 25 mm device for samples larger than 10 mL
-       Sterile options available

Applications
-       Hard-to-filter heavily particulate laden samples
-       Dissolution testing
-       Content uniformity
-       Concentration analysis
-       Routine sample preparation
-       Food analysis
-       Environmental samples
-       Composite assay

Safety
High pressures can be obtained when using syringes. The smaller the syringe the higher the pressure that can be generated. As a general guide, the following pressures can be obtained by hand with the syringes indicated: 20mL- 30 psi; 10mL- 50 psi; 5mL- 75 psi; 3mL- 100 psi; 1m- 150 psi. Each user should determine the pressure they can generate by hand with a specific size syringe and take appropriate safety precautions not to exceed the recommended rating for the device used. If these limitations are exceeded, bursting of the device may occur.

Rota-Filler 3000® 

  
Reagecon Price €150

Patented, adjustable nozzle rotates to three positions for maximum comfort and convenience.

Contoured grip allows for relaxed hold to reduce hand strain.

Three speed control options—high, low, and gravity.

The Rota-Filler 3000 combines a powerful motor with a lightweight, ergonomic design, a reflection of our commitment to the comfort of the end user. Features such as textured grip, hand-neutral design for right- and left-handed users, concave triggers, and convenient controls ensure the filler fits comfortably in your hand for many hours of filling and dispensing.

Pipetting speed is easily set. Slide the speed switch between two operating modes—blow-out or gravity. Select the low or high range in blow-out mode to dispense the remaining liquid in the pipette. Flip to gravity mode for use with “to contain” pipettes and dispense the liquid without the motor.

Filler accommodates glass and plastic pipettes ranging in volume from 1 to 100 mL. The hydrophobic 0.45µm filter in the autoclavable polypropylene nozzle prevents contamination. A red low-battery indicator signals when the batteries need to be recharged. Use filler during recharging, or place it in the included stand or holder. Includes two replacement 0.45µm filters, a dual-position charging stand, and a magnetic/wall-mountable holder. Filler measures 170 x 47 x 143mm.
