Microfiltered with a 0.45 micron membrane; suitable as an EM fixative when a methanol free solution is not necessary.

 

Formaldehyde Aqueous Solution (Paraformaldehyde Aqueous Solution) EM Grade

Paraformaldehyde – methanol free solution. A more efficient and rapid penetrant fixative used in combination with Glutaraldehyde and Acrolein fixatives. Easy to break, prescored, 10 ml ampoules sealed under inert gas, or 100 ml bottles.

CONTAINS NO PRESERVATIVES

In addition to our complete line of Formaldehyde solutions shown above we have now added to the line.

Since the DOT (Department of Transportation) has changed the definition of what a non dangerous solution of formaldehyde is to under 10%, we are now offering an 8% and a 4% solution. This will allow us to ship overnight as well as overseas without any hazardous charges saving our customers a good deal of money.

The quality of our 8% and 4% aqueous Paraformaldehyde solution is as good as all of the other concentrations that we offer.

Formaldehyde/Zinc Fixative

Prepared: Ready-to-use.

Features:

• Preserves fine nuclear details
• Good for immunostaining
• Contains no mercury
• Can be used with automated tissue processors
• Works well with standard and special stains because zinc is a stain enhancing mordant

For a complete procedure and protocol for the use of these washes and fixatives please see the following site: www.neuroscienceassociates.com/perf-solution1 or 2 or 3.htm.

If you want a custom wash or fixative made please just let us know and we will be happy to make you whatever you require.

Technical Tip:

The Fixative for Use in Fixing Cornea

CoreDish™ Multiple Biopsy Containers Half Prefilled with 10% Formalin

Few recommendations concerning how the biopsies should be handled have been published. Performing a large number of biopsies means an increase in the number of containers handled and consequently a technical overload of the transmission network, which occurs without any financial counterpart. A new approach had to be developed in order to increase productivity.

We are proud to offer a multi-compartment container in the shape of a dish and half prefilled with 10% Neutral buffered Formalin, for holding and transporting biopsies. It is supplied with a leak-proof closure with O-ring ensuring total protection of contents. It conforms to OSHA directives. These CoreDisn™ measure only 15mm H x 95 mm Diameter. Each compartment is clearly identified to allow proper placement and visualization of the biopsy being inserted. Thanks to CoreDish™ it is no more necessary to use a multiple of individual containers, thereby reducing cost and risks of confusion.

CoreDish™ available in many configurations to serve in different biopsy, such as prostate, upper GI tract and lower GI tract. A label allows recording the related information, patient ID, doctor, date and time.

M970-D5B-2 CoreDish™ Breast Biopsy Container

Half Prefilled with 10% Formalin

This multi-compartment container (out of five compartments, four are labeled: LUQ, RUQ, LLQ, RLQ) in the shape of a dish and half prefilled with 10% Neutral Buffered Formalin, for holding and transporting biopsies. It is supplied with a leak-proof screw closure with O-ring ensuring total protection of contents. It conforms to OSHA directives. The dish measures only 15 x 95 mm in diameter. Each compartment is clearly identified to allow proper placement and visualization of the breast biopsy being inserted. A writing area for patient information is provided.

M970-D8P CoreDish™ Prostate Biopsy Container

Half Prefilled with 10% Formalin

For prostate biopsies. Eight compratments. Leakproof seal with O-ring lid. An area for patient information is provided. Seven labeled compartments: Base, Lateral Base, Medium, Lateral Medium, Apex, Lateral Apex.

Form-Zero™ Formaldehyde Reducing Agent

From Formalin to Drain in 20 Minutes

Form-Zero ia a unique formaldehyde reducing agent that safely and quickly neutralizes 10% NBF (4% Formalin)(4% Formaldehyde) and as well 4% gluteraldehyde. No pH adjustments required and this will not clog drains.

NeutraGreen™ Neutralizer

Transforms waste formalin into an odorless, 100% nonhazardous material. Comes in liquid form with no powders to mix or dissolve. One of the fastest neutralizers available with a reaction time of only 2-3 hours. Third-party environmental data confirms NeutraGreen™ will neutralize waste formalin to a material that is non-toxic as well as non-hazardous.

NeutraTest™ Strips

Residual Low Range Formaldehyde Test Strips

Test Strips optimized for the NeutraGreen™ liquid neutralizer. Immerse strip in treated waste solution and results will be rendered in 90 seconds. Much more efficient and less costly than conventional test kits.

Formalin Spill Control; F-gard- ER

For the handling and disposing of formaldehyde containing solutions. It immobilizes, cools, and contains spills. As well, it reduces the escape of formaldehyde gas and significantly reduces formalin concentration. F-gard- ER aids in reducing exposure to formaldehyde gases by immobilizing the formalin and transforming it to an easily removed semi-solid mass. The mass cools rapidly minimizing formaldehyde off-gassing.
