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

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.

M970-D8UGI CoreDish™ Upper GI Biopsy Container

Half Prefilled with 10% Formalin

For upper GI track biopsies. Eight compratments. Leakproof seal with O-ring lid. An area for patient information is provided. Seven labeled compartments: Gastric Card, Gastric Body, GE Junction, Gastric ATR, Distal Esophage, Pylorus, Duodeum.

M970-D8LGI CoreDish™ Lower Gi Biopsy Container

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.
