"Oranges and Lemons...." Test Kits for Fruit from "Results Now

DON'T COMPARE YOUR APPLES WITH ORANGES! (Or Pineapples with Tomatoes).

Acidity in fruit is an important factor in determining maturity. Many fruits have high acidity early in the season, making them unacceptable to consumers, even though they meet minimum Brix (sugar) standards. Several fruits have specific Brix/acidity maturity standard required for domestic or export commerce.

RESULTS NOW Titratable Acidity tests in kits of 10 and 20 tests are available in the following configurations:

% Citric Acid in Cranberries              Range 1.6 - 3.6%

% Tartaric Acid in Table Grapes        Range 0.4 - 0.9%

% Citric Acid in Oranges                   Range 0.8 - 1.4%

% Citric Acid in Tomatoes                Range 0.34 - 1.0%

% Citric Acid in Lemons and Limes    Range 4.0 - 6.2%

% Citric Acid in Grapefruit                Range 1.2 - 2.0%

% Malic Acid in Apples and Pears     Range 0.36 - 0.8%

% Citric Acid in Pineapples              Range 0.70 - 1.60%

In development are specific TA tests for Mangos and Strawberries. If anyone has a need for tests for other fruit, please let us know and we shall endeavour to have specific tests developed.

Looking for an Inexpensive but High-Quality Balance? Look at Acculab!

Novasys have recently been appointed distributors for the Acculab range of precision balances.

Acculab offers a broad spectrum of electronic weighing instruments for virtually all applications, from laboratory analysis to the highest capacity scales for use in industry, trade and commerce.

Whether it's a precision balance used in teaching, a portable balance for sample analysis in environmental sciences, or a counting scale for incoming inspection, every Acculab instrument is tailored to its area of use.

Acculab began marketing weighing instruments in 1986, and by 1989 was already manufacturing its own products. Within just a few years, Acculab had become one of the leading suppliers of weighing instruments in the US.

Since 1997 Acculab has been a member of the Sartorius Group, one of the largest international players in the field of mechatronics. Acculab draws on the expertise, the supplier network and, most importantly, on the pioneering technology of Sartorius.

The new Acculab product portfolio is designed under the direction of the Sartorius Group and is manufactured in the US, Germany and China.

Acculab products are sold worldwide through dedicated authorized dealers. This ensures local support and responsive service, even for products that have been in use for many years.

In 2005, Acculab offers a complete new line of products. From the ALC Series of laboratory balances for professionals to the all-new Pocket-Pro portable balances, Acculab presents high-performance instruments in every product category. Acculab addresses the needs of the customer and develops product features that are as practical as they are unique. One of the featured design examples are the world's first stackable electronic weighing instruments for convenient storage and transport.

Paper Change in Leneta 5DX and 2DX Charts

We have been advised by The Leneta Company that, to get a needed improvement in the quality of the paper used for making forms 5DX and 2DX, they have had to change paper suppliers.

This has resulted in a slightly lower Y-reflectance in the new paper than that in the old paper.

The new batch 3423 using the new paper has an approximate Y-reflectance of 83, whereas the “current” batch 3304 has an approximate Y-reflectance of 87.

For most users, the difference in reflectance should have no effect on paint test results.

However, in cases where the test paint is not applied at full hiding, an effect on hiding power or opacity measurements may be observed due to the increased reflectance of the white area.

It is Leneta’s experience that the more critical hiding power measurements are usually carried out on charts such as 2A, 2C and 3B. However, some customers do use 2DX and 5DX for this purpose.

If you would like to receive some samples of the new batch to test, please let us know, and we will send these to you.
