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. CONTAINS NO PRESERVATIVES

The Fixative for Use in Fixing Cornea
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.
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.

24147 | NeutraTest™ Strips | 100/bottle |
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.
